WEBB worked on the City’s WRF #1 project, which involved a single sludge storage tank that mixed primary and secondary sludges. The combined sludge was high in phosphorus and prone to struvite formation in the dewatering systems, prompting the need to separate the sludges to enhance facility operations. WEBB modified the old abandoned chlorine contact basin (CCB) and repurposed it into a two-cell sludge holding tank, incorporating an aeration/mixing system in the new storage tanks. The team removed the existing strain presses and replaced them with two rotary drum screens to effectively screen the sludge before delivering it to the primary and secondary tanks. Additionally, a new transfer pump station was constructed to convey the stored sludge to the gravity belt thickener and centrifuges for dewatering.

As part of the project, WEBB relocated the existing sludge and dewatering MCCs into a new powerhouse electrical building. This extensive work took place while WRF #1 remained operational, and WEBB collaborated closely with the City’s Operations Staff to develop detailed plans for piping and electrical cutovers, ensuring continuous operation throughout the process.

WEBB is providing design services for Phase 2 of this project which consists of installing a second centrifuge and removing the remaining belt press. In 2018, the City replaced one of its existing belt presses with a centrifuge to improve dewatering. Since that time, the City has seen an improvement in the process performance, especially in light of the dryer being off-line for an extended period of time. The dryer solids coming from the centrifuge has reduced the City’s hauling costs compared to the performance of the old belt presses. WEBB prepared the construction documents for the previous installation. Even though provisions were made during the original design, there are still some unique challenges to this project.

This includes:
• Keeping the facility operational throughout the construction and commissioning
• Verify the structure and foundation against current building codes. • Quick selection and pre-purchase of the new centrifuge prior to finalizing the design, bidding, and construction
• Removal of the roof structure to remove the existing belt press • Temporary facilities to convey dried sludge to trucks for hauling in order to replace the existing screw conveyor with a continuous serpentine belt conveyor
• Construction of a new gravity centrate effluent pipeline from the centrifuge area to the anoxic zone of the oxidation ditch to help control struvite formation

RFP NO. 25-034AT
The City of Corona identified two antiquated motor control centers (MCCs) that needed replacing. These MCCs were critical for plant operation. The first was for the main influent pump station (Sunkist Lift Station), and the second was for the VFD-driven aerators at the Aeration Basin. The City selected WEBB to design the MCC replacements. The design documents were developed, and the project was bid out and awarded to a Contractor. The construction is currently underway and will be finished in 2025.

One of the key objectives for this design was to keep the facility operational during the MCC replacement. To accomplish this, our team determined that the best approach would be constructing electrical houses (E-Houses) for each MCC. This would require re-routing power and controls from the existing MCC locations to the new E-Houses. Then, the existing electrical rooms would have the associated MCCs and gear removed. Our team must also understand and include the City’s standards for the gear and controls. Further, we have assisted the City in purchasing the new MCCs directly so that their lead time would not affect the Contractor’s delivery of the project on time.

The existing Western Riverside County Regional Wastewater Authority (WRCRWA) Treatment Plant was originally placed in operation in March 1998 and was constructed as a design build project. The design capacity is 8.0 million gallons per day (MGD). The service area associated with this treatment facility has continued to grow over the past few years and several of the member agencies associated with the WRCRWA require additional wastewater capacity. As such, WEBB designed the 14- MGD plant expansion.

The expansion project included evaluating alternatives to provide additional flow and biological capacity while reducing the overall cost of treatment. WEBB’s design included primary, secondary, and tertiary treatment along with disinfection and solids handling. Working with the member agencies, cost effective alternatives were selected and refined to make this project affordable to build while reducing the cost of treatment.

The project also included chemical storage and pumping.

CHIEF OPERATIONS OFFICER
Wastewater Treatment Plant Expansion and Salt Mitigation Project, City of Beaumont - Brian served as Principalin-Charge and Project Manager for the City’s project which consists of two major components:

Wastewater Treatment Plant (WWTP) Expansion and Upgrade - Final Design The existing WWTP was in need of expansion as it was treating over 75% of its permitted capacity and was in need of expansion. Per the new Regional Water Quality Control Board’s updated Basin Plan, the City was required to begin reducing TDS being discharged from the plant. The City completed a feasibility study to identify the best way to expand and upgrade the plant. The Plant was converted to an MBR process followed by RO for TDS reduction. The Plant also was equipped with fine screening, EQ basin, sludge dewatering, and drying.

Brine Line - Final Design - Brine disposal was an integral part of this project and was a key driver in the type of treatment selected for this project. Without a safe, reliable, and cost effective way to dispose of the brine, this project could not move forward and compliance with the Basin Plan would be impossible. The brine pipeline connecting to the Inland Empire Brine Line (IEBL) was determined to be the best option during the feasibility study, due to cost and certainty of operation. The brine line was sized at 12-inches and was approximately 23-miles long once completed. The pipeline begins at the City’s WWTP and ends near the City of San Bernardino’s WWTP on Waterman Avenue.

WRCWRA Wastewater Treatment Plant, Western Riverside County Regional Wastewater Authority - Brian served as Project Manager for the WEBB Team that designed the 14-MGD plant expansion. The expansion project included evaluating alternatives to provide additional flow and biological capacity while reducing the overall cost of treatment.

WEBB’s design includes primary, secondary, and tertiary treatment along with disinfection and solids handling. Working with the member agencies, cost effective alternatives are being selected and refined to make this project affordable to build while reducing the cost of treatment. The project also includes chemical storage and pumping.

WRF-1 Centrifuge Replacement Expansion Phase 1, City of Corona Department of Water and Power - Brian served as the Project Manager for this project. The purpose of this project was to improve biosolids dewatering performance at Corona’s WRF #1. This was accomplished by replacing one of the existing belt presses with a new centrifuge. The two existing belt presses discharge dewatered solids at approximately 14% DS into the conveyor system and into the truck loading and dryer facilities. It is anticipated that the new centrifuge will produce 16-18% DS which will reduce hauling costs when the sludge is being moved out of the facility and will reduce operating costs when the dryer is in operation.

Wastewater Treatment Plant Expansion (2.4 MGD), City of Imperial - Brian oversaw the full project lifecycle for the City of Imperial’s wastewater treatment plant expansion. WEBB provided preliminary engineering, CEQA compliance, survey, design, bidding support, construction management, inspection, and NPDES permitting. The project included new headworks screening, an extended aeration basin, MBR treatment system, upgraded UV disinfection, screw press dewatering, flow monitoring, electrical and SCADA upgrades, and all supporting process and yard piping. 16 CITY OF CORONA UTILITIES DEPARTMENT

PROJECT EXPERIENCE
Morogno Waste Water Treatment Plant Headworks Replacement, Morongo Band of Mission Indians - WEBB designed new facilities within an existing Wastewater Treatment Plant (WWTP) for the Morongo Band of Mission Indians. The main challenge for this project was to construct and integrate new facilities without disrupting the ongoing services of the WWTP. The project’s design focused on increasing the flow capacity and the effectiveness of the WWTP’s influent screening process. It addresses maintenance challenges by preventing solids and debris from bypassing the screens, thus improving the overall maintenance landscape. A new primary headworks facility is being added to enhance the WWTP’s reliability, with the existing one being preserved as a backup. This improvement not only ensures uninterrupted operation but also significantly improves the work environment for operators due to the upgraded performance of the headworks.

SHANE BLOOMFIELD, PE
SENIOR ENGINEER | WATER RESOURCES
the Inland Empire Brine Line (IEBL) was determined to be the best option during the feasibility study, due to cost and certainty of operation. The brine line was sized at 12-inches and was approximately 23-miles long once completed. The pipeline begins at the City’s WWTP and ends near the City of San Bernardino’s WWTP on Waterman Avenue.

Beaumont WWTP Expansion/Upgrade Preliminary Design, City of Beaumont - Shane served as WWTP Expansion/ Upgrade Civil Engineer on the WEBB Team that prepared the project feasibility study, which analyzed two different options. The first was the Beaumont option which expands and upgrades treatment at the City’s WWTP. For this option three different WWTP configurations were evaluated. In addition, options were explored to dispose of waste brine from the advanced treatment system. The second option was to consolidate treatment with YVWD and deliver all wastewater flow there. For each option, detailed cost estimates were developed taking into account capital cost and O&M costs.

In the end the City Council selected the Beaumont option. The preliminary design includes the preparation of 20%-30% plans for both the WWTP expansion as well as a 23-mile brine disposal pipeline connecting to the IEBL in San Bernardino.

City of Riverside WQCP Expansion, Camp Dresser & McKee – Shane was the Project Engineer for the civil design of this $220 million wastewater plant expansion project. WEBB’s scope of work included survey, mapping, existing utility identification, utility master plan, site grading, yard piping, demolition, drainage improvements, and landscaping.

The Riverside Regional Water Quality Control Plant (RWQCP) currently serves nearly 300,000 residents in the City of Riverside and several neighboring communities. As part of its Riverside Renaissance Program, the City of Riverside embarked on the Riverside RWQCP Expansion, Upgrade, and Replacement Project in order to meet the projected 2025 flows to accommodate capacity requirements, fulfill regulatory discharge requirements to protect the Santa Ana River, and increase production of reclaimed water to augment Riverside’s non-potable demand with recycled water. The expansion project includes replacing 20 million gallons per day (MGD) of existing capacity with 26 MGD of new capacity.

The improvements also include new solids processing facilities.

Temecula WRF Expansion, Eastern Municipal Water District - Shane served as a design engineer for EMWD’s 23-MGD Expansion Project at the Temecula WRF. As a consulting partner to CH2MHill, WEBB was responsible for all aspects of the civil design including site layouts, grading, yard piping, and utility relocations for the 5-MGD expansion of the plant. New facilities included headworks expansion, primary clarifiers, membrane bioreactor, site improvements, and associated yard piping.

PVRWRF Vactor Truck Dump Station Design, Eastern Municipal Water District - Shane served as the Project Manager for the Districts design of a new Vactor Truck Dump Station at the District’s PVRWRF. The Dump Station will meet regulatory requirements and meet the District’s goals of 1) efficient operations, and 2) exceeding minimum safety standards at this Cal/STAR site for ergonomics, employee safety, safe walking surfaces, safe chemical handling, and appropriate signage and controls for vehicular travel. The project included preliminary and final design of a complete Vactor Truck Dump Station to include a roadway system for safe and easy ingress and egress, maneuvering space, containment berms and slopes, dumping area to accommodate up to six Vactor Trucks simultaneously, a connection to sewer for drainage, accessible wash down water, effective and efficient solids handling area, a storage shed for lime, lighting, and vector control strategies. The design package includes all aspects of a fully functional Vactor Truck Dump Station. When complete, the station will become a model for future Vactor Truck dump stations for the District. 18 CITY OF CORONA UTILITIES DEPARTMENT

Project Manager
Kleinfelder
Christina Nishimoto has 18 years of professional experience including working with steel, concrete, masonry, and timber structures and is knowledgeable in the design considerations of all four materials and their respective governing codes. Her design phase work has included attending meetings, coordinating with other professional trades, structural analysis, and detailing.

Wastewater Treatment Plant Expansion and Salt Mitigation Project, City of Beaumont - Christina serves as Structural Project Engineer for the City’s project which consists of two major components:

Wastewater Treatment Plant (WWTP) Expansion and Upgrade - Final Design (Structural) - The existing WWTP needs to be expanded and upgraded. The WWTP is currently treating over 75% of its permitted capacity and therefore must begin the expansion process. Per the new Regional Water Quality Control Board’s updated Basin Plan, the City must begin reducing TDS being discharged from the plant. The City completed a feasibility study to identify the best way to expand and upgrade the plant. The Plant will be converted to an MBR process followed by RO for TDS reduction. The Plant will also add screening, EQ, sludge dewatering, and drying.

Brine Line - Final Design (Structural) - Brine disposal is an integral part of this project and was a key driver in the selection of this project.

Without a safe, reliable, and cost effective way to dispose of the brine, this project cannot move forward and compliance with the Basin Plan would be impossible. The brine pipeline connecting to the Inland Empire Brine Line (IEBL) was determined to be the best option during the feasibility study, due to cost and certainty of operation. The brine line has been sized at 12-inches and will be approximately 23-miles long. The pipeline begins at the City’s WWTP and ends near the City of San Bernardino’s WWTP on Waterman Avenue.

WRCWRA Wastewater Treatment Plant, Western Riverside County Regional Wastewater Authority - Christina served as Structural Project Engineer for the WEBB Team that designed the 14 MGD plant expansion. The expansion project included evaluating alternatives to provide additional flow and biological capacity while reducing the overall cost of treatment. WEBB’s design includes primary, secondary, and tertiary treatment along with disinfection and solids handling.

The scope of work included a ring foundation for two 500,000 gallon steel tanks for surface water, concrete foundations for an operations building, chemical building, and multiple ion exchange tanks.

Point Loma Sedimentation Basin Rehabilitation, City of San Diego - Christina served as Project Engineer on the Point Loma Wastewater Treatment Plant project that consists of 12 existing sedimentation basins constructed as several different projects starting in 1962 through 1996. The result of the varying projects is non-uniformity within the 12 basins. Christina provided support on structural engineering services provided by KLF|SWE which included site evaluation, design and drafting, and construction administration during the construction process. Additionally, Christina provided the design of a pipe support rack.

Pump Stations 1 and 2, City of San Diego Metropolitan Wastewater Department - Christina provided structural calculations and construction support for this design-build project. KLF/SWE’s scope of work included the design of a two-story concrete masonry building at Pump Station 2 as a sub-consultant to Carollo Engineers. The first floor of the building is an electrical room and the second floor is used for storage.

The structural system of the building consists of long span trusses for the roof framing, composite floor, and a mat foundation.

Twin Oaks Central Basin, Central Basin Municipal Water District - Christina served as Project Engineer providing design calculations for the 50 MGD design/build water treatment plant. The design included pump stations, arc flow treatment barriers, two 14 MGD reservoirs, and an ozone treatment facility and filter basin.

Pala Casino Wastewater Treatment Plant, Pala Band of Mission Indians - Christina served as Project Engineer providing the design calculations for this project, which provided the Pala Band of Mission Indians a new wastewater treatment plant and upgrades to the existing lift station.

Phase I Expansion, Riverside Regional Water Quality Control Plant - Christina served as the Project Engineer and provided construction support services for the Phase I expansion.

4. WORK PLAN Project Approach and
Understanding
Our previous/current work at WRF1 includes the
modifications to the Sludge Storage and Screening System, Digester #2 Cover Replacement, Centrifuge Replacement Project, construction oversight of Plant 1A Aeration Panel Replacement, Blowers and Main MCC Replacement, and Sludge Pumping MCC Replacement. This extensive experience has given our team an in-depth understanding of WRF1 facilities, how the Plant operates, and what it takes to maintain operations during construction, cutovers, and commissioning of new equipment.

The digester process and ancillary equipment at WRF1 requires modifications, improvements and replacement as part of this project. Many modifications and “improvements” have been implemented to the digesters since their original construction. Also, operational changes and approaches have changed during that time period. As such, the improvements to the digester mixing, heating and transfer equipment, along with associated pumps is overdue and needed to restore proper operations of this critical solids handling process.

Some of the current plant issues include the following:
• Thickened solids pumping and piping is a bottleneck, impacting the ability to remove solids from the liquid stream processes and get solids to the digestion process.
• Digester heating is insufficient during colder months resulting in temperature running below desired set point. • Digester #3 mixing is an older system with exterior piping. • Solids transfer between digesters is limited.
• Piping is confusing, limited, and could be improved.
• Other items like electrical gear replacement and other piping modifications are needed. 28 CITY OF CORONA UTILITIES DEPARTMENT
RFP NO. 25-034AT
This list is not all inclusive but represents some of the major issues with the current digestion facility. Our team is excited to work with Staff to address these and other issues as part of this project effort. Working with the City during the initial project stages, all issues will be identified and discussed in order to include them in the overall
design approach and solutions. At this time, we offer the following approaches to addressing the current known
issues. Certainly these ideas can and will be modified
as we work together to finalize solutions as part of the project.

1. Thickened Solids Conveyance – Currently all
primary and secondary solids pass through the
solids screening process and are subsequently
thickened by the gravity belt thickeners (GBTs).

Thickened solids are discharged from the GBTs
into a conveyance system and then pumped to
the digesters. The RFP identifies a need for 3
new thickened solids pumps and new piping to
the digester feed valves. This is a critical step
and will address bottleneck issues in the current
system to allow for design flows to be conveyed
to the digesters without limitations. It may
also be appropriate to consider if the auger
system could be removed from the process
and pumps installed to receive solids directly
from the GBTs. If this option proves viable,
then one mechanical step could be removed
from the process, which reduces equipment
to be maintained. With staff, we would consider
the operational and maintenance benefits and
consequences of these different approaches to
solving the current thickened solids pumping
issues. We are confident the best solution can be
accomplished.

2. Digester Heating – The existing heat exchanger
and pumping systems are inadequate for the
digestion process and are not able to maintain
digester temperatures during colder months.

We will size these heat exchangers and pumps
together, based on current and future loads and
maximum heating requirements to make sure the
system is capable of maintaining the digesters at
the desired 98°F. Each digester heating system will
be sized for its maximum requirement, which would
be if all incoming solids were delivered to a single
digester during the coldest month of the year. This
allows for greatest flexibility in operations without
limiting options in how the digesters are operated.

3. Digester 3 Mixing – The mixing system in Digester
3 will be replaced with a Vaughan Rotomix system,
like Digesters 1 and 2. The mixing system will
include internal piping allowing for the exterior
piping to be removed.

4. Solids Transfer – Currently the digesters are
running with Digester 1 and 2 serving as primary
digesters and Digester 3 is running as a secondary
digester. A single pump is installed to allow for
this transfer of solids from Digesters 1 and 2 to
Digester 3. There is some limitation in the ability to
transfer solids in other ways. It would be beneficial
to have the ability to transfer solids from any
digester to another, allowing digesters to be taken
offline for maintenance or for other operational
changes as needed. In addition, there are two
(2) pumps that transfer solids from Digester 3 to
the dewatering process. One option would be to
include a three (3) pump system that allows for
the transfer of solids from any digester to another
and also allows for transfer of solids to dewatering
from any digester. This pumping system would
provide maximum flexibility and redundancy for the
digestion process.

5. Piping – Working with staff, the piping can be
simplified, provide needed flexibility and cleaned
up to improve the facility. Simple improvements,
like the solids transfer pump modifications, heat
exchanger piping improvements, and general
pipe cleanup improve the ease of operating this
facility and understanding how pumping and piping
systems work, improving the ease of operations.

One of our goals will be to help improve piping as
feasible.

Our team will work with the City to fully understand
the project needs and goals and implement solutions
that make sense for the City. We are confident the
current limitations and challenges can be significantly improved with relatively simple changes to the
pumps, piping, valving and controls. These changes
will improve the overall operability, flexibility and
performance of the digestion system.

Project Management &
Methodology
Project Management Approach
WEBB’s approach to project management is centered
on proactive communication, schedule accountability,
and consistent delivery. Brian Knoll, PE will serve as
Principal in Charge, providing executive oversight and
resource support. Shane Bloomfield, PE will act as
Project Manager, overseeing daily coordination, technical execution, and progress tracking to ensure alignment with City expectations.

Our team’s familiarity with WRF 1 operations and recent MCC, centrifuge, and sludge processing upgrades
allows us to anticipate and manage risks, minimize plant disruption, and accelerate design and implementation.

Communication & Coordination
Shane will be the point of contact, coordinating directly with City staff, subconsultants, and operations teams.

Regular project meetings, prompt issue resolution, and
transparent updates will keep all parties aligned. Brian will provide support on contractual matters and ensure timely decisions when escalated.

Scope, Schedule & Budget Management
We will use a clear Work Breakdown Structure (WBS) to
manage tasks and ensure budget alignment. The project
schedule—developed in Microsoft Project—will be
tracked against milestones, and corrective actions will be implemented for any variances. Budget monitoring will be ongoing, with earned value analysis and scope adherence built into monthly reporting.

Quality Control
WEBB’s QA/QC process is embedded at every project
stage. Senior technical leads conduct peer reviews of all submittals to ensure clarity, accuracy, and constructability.

We incorporate City feedback early and often, validating each phase before moving forward.

Risk & Issue Management
A centralized tracking log will document and monitor
project risks and open issues. Shane will work closely
with City operations staff to resolve field constraints and proactively address schedule impacts, procurement
delays, or system cutovers.

Kickoff & Delivery Plan
At project initiation, we will host a design kickoff
workshop with City staff to confirm priorities, establish communication protocols, and finalize the project delivery plan. Our approach ensures design deliverables are
accurate, review cycles are efficient, and construction can QA/QC PROCESS proceed without disruption to plant operations.
