CITY OF BANNING
STAFF REPORT
TO: CITY COUNCIL
FROM: Arturo Vela, Acting City Manager
PREPARED BY: Shah Nawaz, Deputy Water/Wastewater Director Art Vela, Acting City Manager
MEETING DATE: August 26, 2025
SUBJECT: Consideration of Resolution 2025-118, Approving Amendment No.1 to the Professional Services Agreement with Kimley Horn in the Amount of $112,928.00 for Additional Environmental Services for the Wastewater Treatment Plant Upgrades Project.
RECOMMENDATION:
Adopt Resolution 2025-118.
BACKGROUND:
The City of Banning Wastewater Treatment Plant (WWTP), also known as the Water Reclamation Facility, is responsible for the collection, treatment, and disposal of municipal sewage. The City has determined that the WWTP requires both capacity and treatment process improvements to accommodate community growth, produce recycled water to strengthen the City’s water supply portfolio, and comply with upcoming wastewater effluent discharge quality permit requirements.
To advance the project, the City must comply with the California Environmental Quality Act (CEQA).
Because the project may also receive federal funding, staff recommends preparing an environmental clearance document that satisfies both State requirements under CEQA and Federal requirements under the National Environmental Policy Act (NEPA).
On February 22, 2024, staff issued a Request for Proposals to firms on the City’s approved On-Call Environmental and Engineering Consultant Services list. One proposal was received from Kimley-Horn.
Following evaluation, staff recommended, and the City Council approved via Resolution 2024-70 on May 14, 2024, the award of a Professional Services Agreement to Kimley-Horn in the amount of $192,892.
Subsequently, on February 25, 2025, the City Council approved Resolution 2025-30, awarding a Progressive Design-Build Agreement to AECOM/W.M. Lyles, A Joint Venture, for Phase I (design) of the WWTP and Recycled Water Upgrades. To produce Title 22 compliant tertiary-treated recycled water for landscape and irrigation use within the City, the treated wastewater effluent must undergo an additional process called Reverse Osmosis (RO) to reduce total dissolved solids (TDS, as in salts and nutrients) concentrations. This process generates a by-product known as RO reject (brine), a highly concentrated salt solution, which must be further dried and disposed of at designated waste facilities.
Initially, the City anticipated discharging brine to the neighboring City of Beaumont’s wastewater collection system, which conveys brine to the Inland Empire Brine Line under the jurisdiction of the Santa Ana Regional Water Quality Control Board (RWQCB), ultimately discharging to the Pacific Ocean.
However, because the City of Banning is primarily within the jurisdiction of the Colorado River Basin 1000
RWQCB, the Santa Ana RWQCB did not approve the proposed interconnection and discharge.
As a result, the City must construct approximately 20 acres of lined brine drying ponds. The existing CEQA professional services agreement with Kimley-Horn did not include environmental clearance for these brine drying ponds, making an amendment to the current scope necessary.
JUSTIFICATION:
The planned upgrades at the WWTP are classified as a “Project” under the California Environmental Quality Act (CEQA) and must comply with all applicable CEQA requirements. In addition, compliance with the National Environmental Policy Act (NEPA) will position the City to receive potential federal funding.
Kimley-Horn has submitted a proposal (Amendment No. 1) in response to the City’s request for additional CEQA/NEPA services to address the newly identified requirement for approximately 20 acres of brine drying ponds. The proposed amendment, in the amount of $112,928, was evaluated by staff and determined to be acceptable, with the fee consistent with projects of similar scope and complexity.
Kimley-Horn is a highly reputable firm, currently under contract to provide CEQA/NEPA services for the remainder of the WWTP upgrades, and has the necessary expertise and resources to complete the additional scope of work in a timely and thorough manner.
FISCAL IMPACT:
The Amendment No. 1 proposal in the amount of $112,928 to the existing Professional Services Agreement will be funded by Account No. 681-8000-454.90-78.
ALTERNATIVES:
Do not approve Resolution 2025- 118. The WWTP upgrade and improvement project will not be able to move forward without compliance with CEQA and NEPA.
BUDGETED?:
Yes
CONTRACT/AGREEMENT:
Yes

Executive Summary
The City of Banning { City or Banning) owns and operates the Banning Wastewater Treatment Plant { WWTP). The objective of the Banning WWTP and Recycled Water Upgrades Project { Project) is to enhance the WWTP to comply with impending Regional Water Quality Control Board Order { Board Order) requirements and Title 22 standards for recycled water.
The scope of this report Includes defining the following:
Reclaimed Water Demand
Anticipated Regulatory Approvals
Description of Existing Unit Processes
Influent Characteristics
Effluent Limits
Furthermore, the following critical items are included in the proposed Improvements:
Overview
Design Flows
Process Modeling, Evaluation, and Selection
Description of New Unit Processes

o SCADA
o Miscellaneous
The existing treatment plant includes primary and secondary treatment processes, with chlorine disinfection prior to disposal into on~site percolation ponds. The primary treatment involves a mechanical bar screen, with a manual bypass screen, followed by a vortex grit chamber and primary clarifiers. Screenings are processed through a washer compactor before being collected in a bin for disposal. Grit is processed in a hydrocyclone and classifier before being dropped into a bin for disposal. The screened and degritted effluent is settled in two primary clarifiers.
Secondary treatment consists of trickling fillers and secondary clarifiers. Secondary sludge is pumped to the headworks for co-thickening with the primary sludge. The sludge can be thickened before being conveyed to the digesters, but the gravity sludge thickener is currently bypassed. Digested sludge is applied to the drying beds.
After investigating some options for upgrading the trickling filter system, it was determined that the option that would best meet the City's objectives was decommissioning the trickling filter system and replacing it with a membrane bioreactor { MBR) system. MBR produces the best water quality, positioning the City to supply WWTP effluent to recycled water customers. The Sun Lakes Country Club will be !he City's primary recycled water customer, with an expected demand of 0.76 Million Gallon per Day { MG ).
Design Criteria Report
City of Banning Wastewater Trealment Plant and Recycled Waler Upgrades A preliminary BioWin model was created for the proposed facilities. The effluent limits aim to achieve Board Order and Title 22 requirements. Two different activated sludge process configurations were modeled. One is a conventional modified Ludzack- Etlinger ( MLE) process configuration, where the return of activated sludge { RAS) and mixed liquor return ( MLR) from the aerobic zone are both delivered to the anoxic zone. In an effort to avoid the recycling of high dissolved oxygen loads to the anoxic zone resulting from an elevated RAS flow and DO concentrations, which would inhibit denitrification, an alternate MLE configuration was considered. This alternative configuration involves rerouting the RAS to the aerobic zone and relying on the MLR to introduce both nitrate and biomass to the anoxic zone.
The proposed upgrades to the existing Banning WWTP include:
Enhancements to the ferric sulfate storage and dosing system Addition of one primary clarifier, if needed.
Construction of a new MBR system, which includes
o Installation of new fine screens ( 2 mm)
o Construction of new aeration basins
o Installation of new aeration blowers, each with new aeration diffusers and an internal mixed liquor return pump
o Installation of new membrane tanks
o Installation of new mixed liquor pumps
o Installation of new scour blowers
o Installation of waste activated sludge pumps
Construction of a new chlorine contact basin with new effluent pumps Installation of rotary drum thickeners
Conversion of the existing secondary digester into a primary digester, including the installation of mixing pumps and a heat exchanger.
Installation of a new RO facility, either at the WWTP or at Sun Lakes Country Club o Construction of salt evaporation ponds or a brine line, depending on which RO facility location is selected

City of Banning Wastewater Treatment Plant and Recyded Water Upgrades VII
1. Introduction
The City of Banning ( City ) owns and operates the Banning Wastewater Treatment Plant ( WWTP). The City engaged N2W Engineering to complete the preliminary design of the WWTP upgrades at the current rated capacity of
3.6 MGD.
The WWTP effluent is currently in compliance with discharge requirements, but it requires significant upgrades to comply with impending total nitrogen ( TN) discharge limits by the Regional Water Quality Co ntrol Board ( RWQCB).
In addition , the existing Trickling Filters ( TFs}, which perform secondary treatment, have reached their end of life.
By replacing existing equipment with new faciliUes that can treat the water to Title 22 standards for recycled water , this will allow the City to meet the impending RWQCB requirements as weU as use the WWTP effluent to serve existing and future non-potable water customers.
Sev era l upgrade options were in ~ially considered in consuttation wtth the City, including options for upgrading the TFs by replacing the plastic media , followed by denitrificaUon fitters to achieve the required TN limits. This effort included assessing the condition of the TFs. Preliminary cost estimates confirmed that it would serve the City better to construct a new membrane bioreactor ( MBR) facility and decommission the existing TFs. The new MBR system would nol only prov ide better results but would also allow for reuse by produc ing an effluent suitable for direct use in a reverse osmosis (RO ) desalination facility .
This design criteria report (OCR) documents the upgrades required to meet the new limits .
1.1 Assumpt ions
This OCR has been prepared based the following assumptions :
1. The planned rehabilitation and upgrades for the Project will be designed and constructed via a Progressive Design Build ( PDB) delivery.
2. The City has a limited budget for the Project, and the progressive design process would be conducted to maximize benefits for the City within the available budget.
1.2 Reclaimed Water Demand
The City has an exist ing non- potable water system that delivers water from a non-potable groundwater well, Well M7, to Sun Lakes Country Club for irrigation use. The Ctty has begun constructing a 24-inch diameter pipeline to connect the existing non-J)Olable waler pipe to the WWTP. The backbo ne pipeline is expected to be complet ed , tested, and accepted by mid- 2024 . Once reclaimed wa ler becomes available from the upgraded WWTP, ! he WWTP will replace Well M7 to serve Sun Lakes Country Club as part of !his Project. Typica l annual demand for the Sun Lakes Country Club is 850 AFY ( 0. 76 MGD).
Since the Sun Lakes Country Club is located on the wester1y end of the City, other potential customers listed in Table 1 will be within proximity to receive recycled water . Figure 1 on the following page shows the planned backbone pipeline and laterals to the potential recycled water customers.

Constructing the latera ls to the other customers will be a future development. More information regarding the City' s reclaimed water needs can be found in the 2024 Feasibility Study ( attached to the RFP).
1.3 Anticipated Regu lato ry Approva ls
Permit review and issuance , as well as compliance and verification , are essential parts of this Project, involving close coordination with regulatory agencies. The Project must be evaluated under the California Environmental Quality Act ( CEQA), and the City of Banning will have to provide discretionary approval for the Project as the CEQA Lead Agency.

2. Description of Existing Unit Processes
2.1 Plant Overview
The Banning WWTP has a capacity of 3.6 million gallons per day ( MGD) and is designed to treat wastewater to secondary standards . The WWTP consists of primary treatment, secondary treatment, solids handling, disinfection Design Cri teria Report
City of Banrvng Wastewater Treatment Plant and Recycied Wate, Upgrades Pagel 1030
currently not in use), and evaporation/ percolation ponds. The primary treatment system consists of a mechanical bar screen, compactor, grit removal system, and cyclone separator. Effluent from headwor1< is gravity fed to two primary clarifiers. Primary effluent is pumped to two Trickling Filters, each rated for 1.8 MGD. The Trickling Filter effluent is sent to two secondary clarifiers .
Secondary effluent flows through a chlorine contact chamber and is then discharged to 10 unlined evaporation/ percolation ponds which recharges the Cabazon Groundwater Basin . This recharge is provided only through surface percolation , and no injection wells are used by the City.
Primary and secondary sludge is processed via two primary anaerobic digesters. A second- stage digester is currently used as a sludge holding tank before thickened sludge is sent to the sludge drying beds. Sludge is allowed to dry and then is hau~ d offsite for final disposal. A gravity thickener was used to thicken secondary sludge but is currently not in service.
The quantities of wastewater generated are proportional to the City' s population and the water used by its residents .
The average flow of wastewaler collected in the City in 2022 was 2.06 MGD.
An overall process schematic of the existing WWTP is shown in Figure 2 .

2.2 Headworks
The existing headworks consist of a chemical feed system , bar screens, screening compactor, grit tank, and grit washer and cyclone. The chemical feed system includes a ferric sulfate feed tank and dosing pump skid ; this system is in operation for~ months of the year. There are two bar screens: one 0.25-inch opening multi rake mechanical bar screen ( in operation) and one 1.5-inch manual screen ( not in operation). The 0.25-inch bar screen is designed to handle 3.6 MGD average daily now and maximum design flow of 5 MGO. The screening shaffless conveyor compactor has a maximum solid loading rate equal to the solids generated by the rated plant flow of 3.6 MGD. The Oe5' gr, Crileria Repo, 1
City o( Banning Wasi. water Treatm• nt Plant and R8cycled Water Upgrades Page 4 18-foot diameter vortex grit basin is designed to handle up to 30 MGD , assuming an HRT of 2 min, and the grit washer and cyclone have maximum flow rates of 3.6 MGD .
2.3 Primary Clarifiers
There are two existing circular primary settling clarifiers that can accommodate an average flow of up to 3.6 MGO.
The dimensions of the ex isting units are summarized in Table 2.

2.4 Equalization Basin and Pump Station
Currently, the City is in the process of designing an Equalization { EQ) Basin and Primary Effluent Pump Station . The EQ basin will be located in the existing stormwater detention pond and will have a capacity of 3.5 million gallons.
The pump station will have three submers ible pumps, each rated at 3.6 MGD. Since primary clarifier effluent will be directed to the new EQ basin, this EQ pump station will replace the existing primary effluent pump station.
2.5 Chlorine Contact Tank
An existing chlorlne contact tank is located at the W'WTP , but the use of a disinfectant has been discontinued . The existing tank is sized for 2.4 MGD and 60 minutes of contact time. The dimensions of the existing tank are summarized in Table 3.

2.6 Effluent Pump Station and Percolation Ponds
The final effluent pump station consists of two ( 2) 15 HP final effluent pumps located on a reinforced concrete chamber adjacent to the chlorine contact tank.
The final effluent is pumped to 10 unlined evaporation/ percolation ponds which recharge to the Cabazon Groundwater Basin. The total surface area of these ponds is 26.5 acres with an operating depth of 2 feet.
2. 7 Solids Hand ling
Sludge generated at the WWTP is anaerobically digested. The existing digestion system includes two primary digesters and one secondary digester. Currentty, only the primary digesters are mixed , heated , and used for digestion. while the secondary digester is unmixed and unheated and is only used for sludge holding and some thicken ing . Assum ing 20 days SRT and 4% solids concentration , the existing primary digesters can accommodate sludge generated from a wastewater flow ol 2.3 MGD under the currenl trickling filter treatment system. A summary Design Criteria Report

of the dimens ions of the existing three digesters is shown in Table 4. A gravity sludge thickener is onsite but is not operated based on past operating experience. Treated sludge is gravity fed to the facility' s drying beds where it remains until approximately 85% of the moisture is removed. Dried sludge is then hau led off for beneficial reuse as a ferti lizer and soil amendment.

4. Effluent Limits
4.1 RWQCB Board Order
On June 30 , 2016 , the RWQCB adopted Board Order R7-20 16-00 15 (Board Order), which describes the Waste Discharge Requ iremen ts (WDRs) and other terms and conditions of operation for the WWTP. The Boa rd Order
09. sign Critena Repoc1
City of Banning Wastewater Treatment Plant and Recycled Water Upgrades Pag117 1032
requires the WWTP to remove constituents that present the greatest risk to groundwater quality such as nitrogen, colforms , and total dissolved solid ( TDS). According to the United States Environmental Protection Agency ( US EPA), the maximum contaminant level ( MCL) for Nitrate as Nitrogen is 10 mg/L. Per the Board Order, it is assumed all nitrogen available converts to nitrate/nitrite so Total Nitrogen (TN) is used as the measurement of concern. The wastewater effluent limitations per the Board Order are outlined in Table 9 .

The WDRs identified TN and TDS as constituents of concern. The WDRs state that effl uent TDS is not to exceed a level of 300 mg/L above the potable water supply ~reasonably protects present and anticipated beneficial uses of groundwater in the area / (typical incremental addition of dissolved salts from domestic water usage is 150 to 380 mg/l.) The level of TDS in Banning 's potable water supply is approximately 200 mg/L, which would result in an effluent TDS limit of approximately 500 mg/L. The new TN limit is therefore the primary parameter of interest to the design of the new membrane bioreactor ( MBR) plant.
Currently, there is no set timeframe for the City to comply with the Board Order.
4.2 Title 22
The City plans to serve recycled water from the 1/1/WTP to the Sun Lakes Country Club (and other irrigation customers in the future ). The WWTP effluent must therefore meet the State Water Resources Control Board , Division of Drinking Water ( DOW) water recycling criteria outlined in the California Code of Regu lations Trt le 22 requirements . These criteria are summarized in Table 10 below.

5.1 Overview
The Banning WWTP will be upgraded to meet the Tille 22 regu lations and the Board Order' s future TN lim it. The MBR system would faci litate reuse by producing an effluent that is suitable to be fed directly to the reverse osmosis RO) desalination facility , which will be necessary to comply with the Beaumont Basin Maximum Benefit Objectives ofTDS and TN.
5.2 Design Flows and Loads
The average dry weather flow for the new faci lily will be 3.6 MGD. The average influent characteristics are assumed to be similar to that indicated by the available data and presented in Table 5 in Section 3.
The average influent characteristics used for design are summarized in Table 12.

Process Modeling, Evaluation , and Selection
Approac h
The main goal of the process modeling was to determine the volumes of the aeration basins required to meet the new effluent limits, in particular, a total nitrogen concentration of 10 mg/L. Due to the limited influent and plant operating data , a more conservative design approach was used than what would be used for a plant where more data is available so that the design could be optimized. The specific design goals and limits are summarized in Table 13.

8 Due to the limited data ava ilable , the BloW in model settings were left as default as much as possible. One change was to revise the membrane tank aeration settings from the default coarse bubble aeration to fine bubble aeration .
This resulted in reasonable model-estimated DO concentrations ( 2 .0 - 4.0 mg/L, depending on the conditions modeled and the loads used ). Another change was to adjust the ha~ saturation DO concentration ( KDO) for nitrite ox idizing bacteria ( NOBs). The default KDO sett ing in the model is 0.50 mg/ l , which is double the Koo for AOBs.
The Koo for NOBs was reduced to match the Koo for AOBs ( 0.25 mg/L).
5.3.2 Process Con figuration s
Two different activated sludge process configurations were modeled. A conventional modified Ludzack-Ettinger MLE) process configuration where the return activated sludge ( RAS) and mixed liquor return ( MLR) from the aerobic zone are both delivered to the anoxic zone, as shown in Figure 3. rT~ MBR Etluent
WAS
Figure 3 Modified Ludzack -Ettinger process configuration In MBR systems , the concern with the MLE configuration is that the combination of the high 00 concentration in the membrane tank and the high RAS ratio of 4.0 can result in excessive DO loads returned to the anoxic zone. Since the heterotrophic bacteria that perform denitriflcation would consume oxygen rather than nitrate , excessive DO may limit denitrification in the anoxic zone. An alternative process MLE configuration often used in MBR systems routes the RAS to the aerobic zone and relies on the MLR to return both nitrate and biomass to the anoxic zone , as shown in Figure 4 .

DeslgnCriteriaReporl
City ol Banning Wasi- ater Treatment Plant and Recyellld Water Upgrades Page 10 Figure4 Alternative Modified Ludzack- Ettinger process configuration Both process configurations were shown to be successfu l for this Project. However, the alternative configuration required excessive MLR ratios ( more than 10 times the influent flow). In addition, the alternative configuration requires splitting the RAS flow equally between all aeration basi ns in service mid-basin. on top of the equa l split of primary effluent required at the inlet of the aeration basins. SRT calculations for the alternative configuration are also more complex since there are three different mixed liquor suspended solids ( MLSS) concentrations in the system anoxic zone , aeration basin excluding anoxic zone , and membrane tank) as opposed to just two for the MLE configuration.
The model process used for design can be the Modified Ludzack-Ettinger Process Configu ration, Alternative Modified Ludzack-Ettinger Process Configuration, or equal.
5.4 Description of New Unit Processes
The WWTP will be upgraded as described below . Where ap plicable, the new equipment will match existi ng equipment as much as possible .
To ensure sufficient redundancy, all major process units, including primary clarifiers , aeration basins, membrane tanks and chlorine contact basins , should be designed to provide the required treatment with the largest unit out of service during max month flows and loads . Assume a maximum-month flow peak factor of 1.2 and load peak factor of 1.25.
Conceptual design drawings of the proposed WWTP upgrades, including a process flow diag ram ( PFD), plant hydraulic profile , site layou t, and piping and instrumentation diagram ( P&ID) are included in Attachmen t A. All conceptual drawings are subject to change by the Design Bu ild Entity ( DBE). 5 .4.1 Head works
The DBE is to perform a condition assess men t on the existing ferric sulfate system and design improvements as necessary. See Tables 42 through 44 in Section 6.1.3 for design guidelines. 5 .4.2 Primary Cla rifier
The 3.6 MGD capacity of the two existing primary clarifie rs does not allow for peak daily flow or redundancy.
Therefore, a third primary clarifier is recommended for the Project. See Table 45 in Section 6.1.4 for design guidelines.
5.4.3 Secondary Treatment System
The existing trickling filters and secondary clarifiers will be replaced with a new MBR system consisting of aeration basins and membrane tanks . The requirements of the new secondary treatment system process units are summarized in Table 14 and Table 15.

5.4.5 Solids Handling
In order to accommodate the 3. 6 MG O plant capacity , it is recommended that the ex isting digesters be reconfigured .
The existing secondary digester can be converted into a primary digester by adding recirculation pumps and heating elements to the system . This will provide a total capacity of 482 ,000--gallons and 24 ,000 gpd of wasted sludge if the three existing digesters are operated in parallel.
Additionally, it is recommended that a new mechanical sludge thickener , such as a rotary screw or drum thickener, be installed to improve the total solids content in the digester influent.
See Table 48 in Section 6. 1. 7 for design guidelines.
5.4.6 RO Facility
In order to comply with the Beaumont Basin Maximum Benefit Objectives to supply Sun Lakes Country Club with re cycled water, a portion of the MBR permeate wi ll be fed to a re verse- osmosis ( RO) facility. There are two options for the RO facility. Option 1 is to install an RO facil ity at the WWTP. Brine will be disposed of in salt evaporation ponds to be constructed at the WWT P site. Option 2 is to insta ll the RO facility at the point- of-use , the Sun Lakes C ountry Club. Under Option 2, brine can be disposed of into the sewer, which would ultimately return to the WWTP, or through a brine line to be built from the RO facility to the Beaumont Wastewater Treatment Plant.
The minimum requ irements of the new RO facility are summarized in Table 13.

Civil Narrative
The site is located at 2242 Charles Street in an unimproved portion of the parcel. The area of improvement is relatively flat and will require grading and drainage improvements to accommodate the new structures. According to the Riverside County flood map effective 08/28/2008 , the site is characterized as an area of minima l flood hazard and does not lie within a floodplain characterized by a 100-year flood. Although flooding is not anticipated, proper grad ing and drainage of the site are requ ired to min imize foundation settlement and overall building performance.
The proposed structures will be surrounded by hardscape and/or native landscape and shall be designed per the California Building Code . Therefore , site improvements shall be sloped away at a minimum of 2% for impervious areas or a minimum of 5% for pervious areas away from bu~ ding foundations for a minimum of 10 feet in both scenarios. In addition to the grading considerations, these improvements are expected to exceed the 5, 000 square feet impervious improvements threshold and will initiate a Water Quality Management Plan. On- site permanent Best Design Critena Report
City ct Banning WasleWater Treetmenl Plant and Recycled Water Upgrades Page 37 1047
Management Practices ( BMPs } are required to capture and treat the anticipated runoff calculated using the rational method . Geotechnical investigations will identify if infiltration is feas ible.
All uti lity services required for the proposed improvements are expected to be provided through underground services. It is anticipated that existing potable water, wastewater, power, and gas services will be extended to the proposed structures , and additional pennitting or approvals will not be required.

Instrumentation and Controls
Proces s Control Na rrative
Process controls will be set up according to industry standards and be connected to the new SCADA system.
Controls should allow automatic operation to the industry standard and the extent possible. The following section summarizes a conceptual process control narrative for DBE consideration.
Aeration control will allow dissolved oxygen ( DO) concentration control in each aerated zone and swing zone. DO setpoints will be operator adjustable and operators will be able to schedule DO concentrations in 30-minute intervals for a diurnal or weekly schedule. The control system will be able to maintain DO setpoints at concentrations as low as 0.2 mg/ Land as high as 2.5 mg/ L. The DO control system would use cascade control with airflow control for the primary loop and DO control for the secondary loop. Blower control will be based on pressure control , including the option of operating in most- open- valve mode. Minimum airflows to each zone will be operator adjustable and initially set to an airflow equf\/ alent to 0.1 scfm/ sf or the minimum airflow required to meet the minimum diffuser airflow as recommended by the diffuser supplier, whichever is higher. Blower controls will include protections against blower damage due to low airflow and overpressure . lf needed , blower controls can also be based on flow or ammonia control in add ition to DO and pressure control.
MLR pumps will include VFDs which will be set up to operate at an operator adjustable ratio to the primary effluent equa lization pumps divided by the number of Aeration Basins in service , i.e. the feed flow to the aeration basins , per basin. The ratio will be adjustable between 2 .0 and 5 .0.
Solids retention time (SRT) is the most important parameter to be controDed at any activated sludge plant, including MBR plants. Ideally, SRT control shou ld be set up to achieve a steady waste activated sludge ( WAS ) flow rate that is only adjusted when either the SRT setpoint changes ( which may be done seasonally) or when a train or a basin is taken out of serv ice. t is possible to achieve this condition when the return activated sludge RAS) ratio ( RAS flow/ Influent flow , where influent flow to the MBR system is the flow provided by the equa lization pumps) is maintained at a constant value. At the WI/I/TP, the RAS ratio will be controlled by the ratio between the flow provided by the mixed liquor transfer pumps , transferring mixed liquor from the aeration bas ins to the membrane tanks. The target for this flow ratio wi ll be 5.0, meaning the RAS ratio will be 4.0. The required WAS mass flow is equal to the biomass inventory divided by the target SRT. In the MBR system , the MLSS concentration in the aeration basin can be calcu lated as a fraction of the MLSS concentration in the membrane tank, where the fraction is 80% (= R/[R + 11) when the typical RAS ratio of 4.0 is used. The solids inventory is the sum of the solids inventory in the aeration basins and the membrane tanks. If the WAS is taken from the RAS stream , which has a slightly higher MLSS concentration , the WAS flow is :
OwAS = ( 0.8.VAS + VMr)/SRT
Where Qw,s = WAS flow rate , gpd
VAB = Volume of the aeration basin in service , gal
V MT = Volume of the memb rane tank in service, gal
SRT = Target SRT. days
If the ML pumps cannot maintain the target RAS ratio of 4.0 for any reason, the 0.8 factor in the equation can be adj usted as required.
Using a stable WAS flow would help the MBR system to produce a consistent effluent qua lity and maintain the biomass at a stable point for optimal performance.
To minimize the accumulation of scum in the system , the WAS shou ld be drawn from the surface of the RAS channel once scum would have had a chance to float , so that scum is wasted preferentially and the so-called scum SRT is less than the system SRT. This approach is also described as a classifying selector by some consultants.
6.7.2 Level of Automat ion
The Project shall include a high level of automation. The plant operators will manually initiate the wastewater treatment plant' s start-up from the Project' s control system. After operator initiation , the control system will manage the plant startup sequences , normal operation, and shutdown sequence fully automatically.
DeSigo Cntefla Report
City of Banning Wastewater Treatment Plant and Recyded Water Upgrades P~IIO Every skid will have its own PLC contro l system and Human Machine Interface ( HM I) and shall be Supervisory Control and Data Acquisition system ( SCADA) transpa rent, i.e., seam lessly integrated into the site SCADA system .
Plant operations will be monitored and controlled via a local operator station using an owner- and engineer- approved SCADA Platform. A development workstation will have the PLC programming software installed , as we ll as the SCADA platform Integrated Development Envi ronment ( IDE) to develop and maintain the project Human Machine Interfaces ( HMls).
Plant monitoring and control will be predominantty carried out from the Central Control Room on Operator Workstations located in the plant administration building . Further control will be available through HM!s located at critical areas of the plant, k>cations to be confirmed during project design.
The design will enable remote off-site access for operator monitoring, technician diagnostics, and control modifications under agreed security measu res. If requested , allowance will be made for the transfer of historical data from the local historian to a central monitoring location.
The capability will be provided to connect laptop HMI units through a local secure, encrypted wireless network throughou t the site to facilitate commissioning and maintenance activities over the life of the plant.
6.7 .3 Plant Control Architecture
The following section summarizes a conceptual plant control architectural pla n for DBE consideration.
The Plant LAN will be a secure Control Center Network within a single control area. The upper- level supervisory control network connects Control Center servers, application servers, and HMls over Ethernet. The contr~ servers and application object servers are installed in a server rack , and each is configured in redundant pairs with secondary network interfaces. The servers host the Wonderware System Platform. The owner and eng ineer shall approve the number of HMI workstations to be provided for operators and supervisors and at the security gate for monitoring and control.
Supplied Architecture sha ll :
Be scalable, as shown in Figure 10.
Be flexible from a connectivity standpoint, as shown in Figure 11.

OesignCnteria Report
City of Banning Wastewater Treatment Plant and Recyded Water Upgrades Page 90 Equipment safety interlocks specified to shutdown equipment "independent of control mode" or other similar descriptions will be active regardless of PLC ( MANUAUAUTO ) or fie ld control station ( ON, LOCAUREMOTE) operating status.
Other software generated alarms will remain active independen t of operating mode , but only affect specified control actions in AUTO ( PLC) and REMOTE ( field ) operating modes.
For all equipment controlled by the PLC, the equipment will receive and display applicable statuses and alarm signals, suc h as operating mode ( LOCAL, RE MO TE, etc.), operating status ( ON , OPEN , CLOS ED , etc.), and alarm status ( FAIL , LOCKED- OUT, etc.).
For multistate devices where actual digital input is not provided , provide PLC k,gic-based on the status of the other inputs to develop the remaining status. For example , for LOR switches use the status ofthe LOCAL and REMOTE inputs to develop and dis play the status of the OFF position .
For all equipment contro lled by the PLC, our DBE team will provide separate displays and poke points for the selection of AU TO/MANUAL operating modes. In AU TO mode, the device will be controlled by the PLC.
In MANUAL mode. the device wi ll be operated by START/ STOP and OPEN/CLOSE poke points , as appropriate. The workstation will display the current operating status of each device and an alarm if the equipment fails to respond to a command signal after an operator-adjustable time period.
PID con trol fun ctions will be performed at the PLC with controller faceplate displays at the workstation .
Standard PID control operator interface will be provided, includ ing AUTO/ MANUAL mode selection:
6 .8.2
o In AUTO, the controller output will be based on the PIO control function at the PLC. o In MANUAL, the output of the controller will be based on an operator set value. o Transfer between MANUAL and AUTO will be bumpless.
o At the workstation . DBE will provide AUTO/ MANUAL selection poke points for PIO-controlled equipment, with graphic loading displays for manual control.
PID loop tuning parameters shall be available via SCADA but will require engineering login to make adj ustments.
Typical Monitoring and Control
The following are some of the typical 110 signa ls that shall be monitored and used to control equ ipment by SCADA:
All Anak,g Transmitters - Transmitter Fail Alarm

Constant Speed Drive - Drive starVstop command , Drive running indication , Drive in auto or remote indication , Drive faulted, PLC calculated drive run time , Fail to Start/Stop, and Diagnostics (confirm specific parameters )
Variable Speed Drive - Drive start/stop command , Drive running indication , Drive in auto indication , Drive faulted, VFD speed set point, VFD speed feedback, PLC calculated drive run time , and Diagnostics (confirm specific parameters)
Chemical Dosing Feed System - Chemical volume quantity used calculated values.
Control Philosophy
The control system will be fu lly automated so that, as far as practica l, all day-to-day operational adjustments and reporting can be conducted from the SCADA scree ns. The level of automation will be consistent with the staffing requirements for the plant.
Skid vendor screens will be incorporated on the SCADA HM I, such that all parameters can be monitored and controlled except where safety concerns dictate local control only or where controls are related to maintenance tasks that can only be carried out locally anyway.
Design Criteria Report
City of Banning Wastewater Treatment Plant and Recycled Water Upgrade, Page 91 1074
Alarms for control network failures will be incorporated including Ethe rnet switches, PLCs , or any network communication where available .
Local manual override will be accomplished with a hard-wired switch except where personnel , equ ipment , or the process are protected by equipment softwa re interlocks that need to be maintain ed at all times.
The system will not be able to create a safe ty issue for the local operator. For example, remote operation should not be allowed if a local manual override is selected .
Shutdown of the pla nt units will be full y automated.
Recovery after a power outage or shutd own will be mostly automatic but will req uire operato r inte rve ntion for the process to begin and may req uire additional operator intervention through the startu p sequence as determined during the plant des ign in ord er to ensure safely and compliance requirements are met.
Automatic and manual operation of the system will be done from the Opera tor Workstations ( OWS) and from wirele ss tablet devices. Additional remote- control access may be incorporated during the transitional operation period using RD P and VPN access built into the SCADA Virtua l Servers and Virtual Machines systems.
