DIGESTED SLUDGE DEWATERING FACILITY, DIGESTED SLUDGE DEWATERING

FACILITY SITE AND RELATED PROJECTS DESCRIPTION

1.1 PURPOSE
The purpose of this Appendix is to describe the proposed Digested Sludge Dewatering Facility Project (Dewatering Facility), show the location and boundaries of the Dewatering Facility Site, and identify relevant projects, studies, reports, and other documents.

1.2 BACKGROUND
The San José–Santa Clara Regional Wastewater Facility (RWF) is an advanced wastewater treatment facility jointly owned by the cities of San José and Santa Clara and operated by the City of San José’s (City) Environmental Services Department (ESD). The RWF serves eight South Bay cities and four special districts including: San José, Santa Clara, Milpitas, Cupertino Sanitary District (Cupertino), West Valley Sanitation District (Campbell, Los Gatos, Monte Sereno, and Saratoga), County Sanitation Districts 2-3 (unincorporated), and Burbank Sanitary District (unincorporated). Figure 1-1 shows the RWF site plan with the location of major treatment processes areas.

Sludge generated in the primary and secondary treatment processes is thickened and anaerobically digested. This digested sludge (DS) is then transferred to open-air, sludge stabilization lagoons for approximately three and a half years and then to the open-air drying beds for another six months. The resulting Class A biosolids product is loaded into trucks and hauled to the adjacent Newby Island Landfill for use as alternative daily cover (ADC). A process flow diagram of the current liquids and biosolids treatment operations is provided in Figure 1-

2. The Lagoons and Drying Beds are shown in Figure 1-3.

In 2008, the RWF embarked on a master planning process to rehabilitate and upgrade its facilities and explore potential process changes. The San José/Santa Clara Water Pollution Control Plant Master Plan (PMP) used an extensive community engagement process to develop overarching environmental, economic, social, and operational goals for the RWF. To support these goals, the PMP envisioned a comprehensive Biosolids Management Plan that would transition from the current open lagoons and drying bed process to an enclosed, mechanical treatment system with the resulting dewatered biosolids hauled off-site. This transition was intended to reduce the footprint of the biosolids management facilities to enable other uses of land currently occupied by sludge stabilization lagoons and drying beds, reduce odors in the surrounding community, allow the City to develop multiple and diversified biosolids end-use DRAFT--Contact the Office of the City Clerk at (408) 535-1260 or [email protected] for final document.

options, and create flexibility to respond to future regulations governing the beneficial use of biosolids.

The PMP was adopted by the San José City Council in November 2013 and by Santa Clara City Council in December 2013, allowing staff to begin critical infrastructure improvement at the Regional Wastewater Facility, including the related projects described in Section 1.5 (Related Projects and Background Studies and Information) of this Appendix. The Digested Sludge Dewatering Facility project is one of the major and high priority CIP projects. [REMAINDER OF PAGE INTENTIONALLY LEFT BLANK]

In 2014, a Biosolids Transition Strategy was developed to address certain specific issues regarding implementation of the transition from the existing biosolids management system to the PMP's recommended system, taking into consideration the changes that have occurred since the technical aspects of the PMP were developed. A new mechanical DS dewatering facility is an integral component of this Biosolids Transition Strategy. The implementation of the new Digested Sludge Dewatering Facility project (Project) was approved at the June 2, 2015, City Council meeting.

The Construction Enabling Site is shown in Figure 1-4, at the bottom of the aerial photograph, labeled as “Main Storage and Laydown Area for Main Plant Work.” Additionally, a staging area for material and personnel for the Digested Sludge Storage Site is located above the triangle area shown in green. Similarly, Figure 1-5 designates the construction laydown and trailer/parking area for the main construction area for the Dewatering Facility. Additional areas may be designated by the City for construction staging, storage, trailers and laydown for the Dewatering Facility.

1.3.2 Environmentally Sensitive Areas
Figure 1-6 shows environmentally sensitive areas at the rear of the Dewatering Facility Site.

Work near this area requires setbacks per City Policy and work in this area requires a permit.

It is anticipated that these areas will be cordoned off during construction and that the Project will proceed without access to them. If work is required in this area, full environmental review will be required prior to permit applications.

There is also the potential for burrowing owls to nest or forage at all planned sites at RWF. All work in this area must be in compliance with the Santa Clara Valley Habitat Conservation Plan.

The Design-Builder shall also comply with all Environmental Mitigation Measures in accordance with Section 4.3 (Environmental Review) of this Amended and Restated DesignBuild Contract. [REMAINDER OF PAGE INTENTIONALLY LEFT BLANK]

1.4 PROPOSED DIGESTED SLUDGE DEWATERING FACILITY
The new Dewatering Facility is anticipated to include new dewatering buildings that would house a mechanical DS dewatering system (i.e. centrifuges); polymer blending and dosage facilities; dewatered cake conveyance and storage facilities; truck loading bays with weighing scales; new centrate pumping systems and, a maintenance shop and various support facilities and systems. It will also include a process control room, Motor Control Center, transformers, switchgear, heating/ventilating/air conditioning systems, break room, kitchen, conference room, showers, lockers, bathrooms, and a parts storage area.

Within the fence line of the RWF, the Project includes transfer pumps and pipelines to convey DS from existing digesters to storage facilities; a new DS storage facility with necessary conveying, pumping, and tankage; new DS pumping systems and pipelines to convey DS from DS storage to the new dewatering building; pipelines to convey centrate from the dewatering process to RWF; and, various new and modified ancillary facilities and systems.

Major elements of the Project and their intended functions were initially described in the Digested Sludge Dewatering Facility Project Definition Report, prepared by Brown and Caldwell and issued on October 1, 2018. Changes were made to the preliminary concepts described in that report during the preliminary services phase of the Project. APPENDIX 4, Technical Specifications, describes the major elements of the Project, their intended function, and technical criteria and requirements.

1.4.1 Indicative Design and Design Development during Preliminary Services.

The PDR included two indicative designs. The indicative designs outlined a baseline concept and scope of the Project developed during the planning stages to assist in obtaining environmental permits and cost estimates. The indicative designs was used as guidance, but did not prescribe to the Design-Builder the final design of the Project. The Basis of Design Report (BDR) has been completed and the final design for the Project is being developed by the Design-Builder by advancing or modifying the indicative designs to incorporate the results of the Design-Builder’s preliminary investigations (e.g. condition assessments, geotechnical investigations, etc.) and to address changes made subsequent to the completion of the indicative designs.

Figures 1-4 & 1-5 present the overall site plans developed by the Design-Builder as part of the preliminary services. The design criteria include a mass balance that was derived from the Project flow and load design criteria to establish sizes and numbers of facilities and system used in the detailed design drawings.

 New digested sludge pump station and pipelines to convey digested sludge from digested sludge storage to the new dewatering building
 New centrate pumping systems and pipelines to convey centrate from the dewatering process back to the new headworks facility within the Regional Wastewater Facility  Various new and modified ancillary facilities and systems Further descriptions of these facilities, including assumptions and criteria used to date can be found in the DPS Design Document (Attachment 4B).

4.5 MINIMUM TECHNICAL REQUIREMENTS
This section describes minimum technical requirements for the Project. The Design-Builder shall complete the design and perform the Construction work in conformance with the minimum technical requirements contained herein.

4.5.1 Operating Strategy
The Project as currently conceived has been assumed to operate continuously (i.e., 24 hours per day, 7 days per week, and 365 days per year). The City intends to staff the facility with operators at all times. Maintenance and management staff are expected work day shifts only.

The operating strategy does not assume use of digested sludge storage or dewatered cake storage as part of routine operations. Instead storage is to be used to allow for planned and unplanned suspension of dewatering operations.

4.5.2 Digested Sludge Flows, Loads, and Design Years
Table 4-1 sets forth digested sludge flow and loading values for sizing the Project. The listed values are projections for digested sludge leaving the anaerobic digesters following commissioning of the Digester and Thickener Facilities Upgrade project (DTFU), which is currently being commissioned.

Estimator Division Issue
Shea 3 Max CJ spacing is 60’ instead of 50’ as indicated in the specifications. This was confirmed as acceptable in emails to/from Black & Veatch.

Shea 3 Concrete mix designs do not include air entrainment.

Shea 3 Concrete mix designs include known cost increases at the end of this year.

Shea 3 Concrete mix designs include extra to account for additional admixtures needed to increase slump.

Shea 3 Assumption of 1’ slab thickness where not indicated for misc. site pads from 60% remains the same.

Turner 8 Overhead doors for loadout facility were specified as Rytec "turbo seals" but were not available in required size. Rytec Fast Seals are quoted. Spec will be updated to match.

Shea 26
Where flushing connections were required/shown to flush extremely long runs of piping, these connections were upsized from 1.5” to 3” materials. This will allow for faster flushing of these particularly long runs.

Shea 31 All excess spoils will be kept onsite. Stockpile locations to remain the same as those from 60%.

Shea 31 Recycled AB has been utilized to keep costs down when possible. Virgin AB has been used under structural slabs.

Maidrand 33
Alternative routing to the Directional drilling path and associated piping (TRS, CEN, WTR3, WTR4, SWPS) due to market feedback from Directional drilling subs on the feasibility of the work.

Shea 40 Supports are all hot dip galvanized except for those within the Sludge Storage Tanks.

Shea 40
Specifications allow for the use of grooved fittings. These are used where applicable. Specific guidance from designer and owner included flanged connections around equipment and valves.

Shea 40
Process air piping is only shown on the P&IDs. Lengths and number of fittings were based on the rough linear footage to where the air is needed and anticipated use of adjacent walls as much as possible
Shea 40
The 8”/14” centrate drain line shown under the 2nd Floor of the Dewatering building is labeled as DIP. Per discussions, this pipe was instead quantified as a SCH80 PVC line.

Shea 40
Additional pipe and fittings were included in the estimate to account for comments issued by owner regarding air releases, single points of failure, etc. These may have been included in DPS drawings. Final coordination will occur as part of 100% design.

Shea 40
No supports were shown outside a very select few. Type and number at this point were assumed based off current pipe routing and what was encountered on the active San Jose Digesters Project.

Shea 40 WTR3 source for Transfer Pump area at sludge storage will come from the lines within the utility tunnels.

Shea 40
Wall spools follow B&V standard details provided, Flange x PE with a weep ring. Exception to this and requested by the concrete tank manufacturer was to had a flush mounted flange x flange spool with tapped holes.

Shea 40
No mechanical drawings show the WTR3 feed to either the four centrifuges or the Centrate Wetwell. The mechanical drawings also do not show the level indicator piping arrangement for the Centrate Wetwell. Quantities for these activities were based off distances from connection point to connection point and a quantity of fittings was included based off anticipated routing.

Maidrand 40 Alternative routing of underground piping were given due to owner requests & cost savings Shea 42 Additional 4” line was included in the Dewatering building to serve as a blowoff from the TRS intake piping to the Centrate Wetwell.

Shea 43
No piping was shown for the seal water or service water at the Sludge Storage Area or the Transfer Pump Area. Quantities are based off of general location of final destination and where Walsh plans to tie-in to existing infrastructure.

Hudson 43
Seal Water stations are currently required in the specifications to be provided by the equipment supplier. The cost model shows this work as self perform by Walsh and the costs have been deducted from the equipment bids.

Hudson 46
The costs for the cake bins in the cost model include bolted/flanged/gasketed connections to simplify shipping, coating and minimize field erection labor and costs. The design specification will be modified for final design to reflect this acceptable modification.
