Engineers, and Approve Budget Amendment
SUMMARY:

City staff request that City Council create a new Capital Improvement Project ( CIP) WW 25-3 McKinley Avenue Force Main Intertie. This project is needed to establish a connection between the Manteca Wastewater Quality Control Facility ( MWQCF) and the Lathrop Consolidated Treatment Facility ( LCTF) to allow for the efficient transfer of wastewater based on demand and system resiliency.

Staff also requests City Council approve an initial budget allocation for the project engineering design by transferring $ 925, 200 from the Wastewater Connection Fee Fund 6030 to the new CIP WW 25-3 through the approval of a budget amendment.

Furthermore, staff requests the City Council approve the attached Professional Services Agreement ( PSA) with Black Water Consulting Engineers in the amount of 771, 001 for Tasks 1-6 under their proposal to complete the engineering design, permitting and bidding assistance tasks needed to award the construction contract.

This agreement is for professional engineering services to conduct a feasibility assessment, basis of design report and design of the force main intertie between the two wastewater treatment systems.

BACKGROUND:

The City treats its wastewater at two facilities: the MWQCF provides treatment for areas located primarily east of I-5, excluding the Crossroads, Gateway and South Lathrop development areas, and the LCTF provides treatment for Crossroads, Gateway, South Lathrop and areas located west of I-5.

An intertie connecting the two wastewater treatment systems is recommended to provide numerous benefits, including increased system reliability, enhanced operational flexibility and efficiency. The proposed intertie would be located between the existing sanitary sewer force main located at the intersection of Vierra Road and McKinley Avenue and would proceed west on Vierra Road and D' Arcy Parkway to the CITY MANAGER' SREPORT PAGE 2

required capacity.

Rehabilitation of the LCTF headworks.

CITY OF LATHROP I MCKINLEY AVENUE FORCEMAIN INTERTIE PROJECT DESIGN 1 To successfully deliver this project, critical work components are establishing the City' s objectives, concerns, and preferences at or before the kickoff meeting. These criteria will serve as the baseline for the development and evaluation of alternative scenarios. Black Water must also be focused and responsive by promptly developing alternative scenarios and early follow- through with subconsultants and outside agencies.

Key risk factors which should be considered in the development of alternative scenarios and design of the project are anticipated to include:

Cost
Construction sequencing
Connections to existing infrastructure
Electrical service reliability
Construction schedule
Community impacts
Right- of- wayconstraints at McKinley Road and Vierra
Road intersection
Safety ( during construction and during operation and
maintenance of the facility)
Reliability and redundancy for LCTF operation
Environmental requirements
Obtaining permits for governing agencies for
proposed force main ( FM) alignment
Coordination with Union Pacific Railroad
Mitigation of these risk factors will be approached based on the City' sobjectives, concerns, and preferences established at the beginning of the Project. Mitigation measures will be presented by Black Water, discussed with the City, and collaboratively decided together. As the project develops, additional risk factors may emerge and will be discussed, with proposed options for mitigation presented to the City.

At this early stage, we understand that City and operations staff may have additional design suggestions. We look forward to having productive conversations if Black Water is selected for this project.

P: 209. 460. 5042 I E: gjones@hacsj. com I 2575 Grand Canal Boulevard, PROJECT DATES: Apr 2019 - Ongoing CONTRACT VALUE: $968, 200. 0 Black Water completed a project engineering report which evaluated five wastewater treatment and disposal alternatives for the Housing Authority' sdevelopments in Thornton. An alternative was selected to decommission the existing WWTF and construct a new pipeline to convey wastewater to an existing Sacramento Area Sewer District (SASD) booster pump station, where the wastewater is eventually transported to a Sacramento Regional County Sanitation District ( Regional San) interceptor system, which then conveys the wastewater to the Regional San treatment plant. Black Water also provided the design of a new lift station, including a wet well with a duplex submersible pump system, an emergency storage tank, 2. 3 -mile long force main, tie- in to existing SASD pump station and decommission/ demolition of the old Thornton WWTF. Black Water is currently providing engineering services during construction and construction inspection services for the project.

A, Murphys, CA 95247 PROJECT DATES: Mar 2015 - Apr 2021 CONTRACT VALUE: $574, 280 CONSTRUCTION COST: $4, 247, 900 Black Water provided engineering design and construction services to correct wastewater treatment plant deficiencies while keeping user rates and annual operation and maintenance costs as low as feasible. Improvements included relocating the headworks facilities to the WWTP and installing a flex rake bar screen with washer and compactor; replacing the influent pump station; replacing 1 mile of the sewer force main; replacing the emergency generator: replacing the aeration system with a fine bubble aeration system in Ponds 1 and 2; adding solar mixers to Pond 4; removing accumulated biosolids from Pond 1; constructing a new concrete disinfection basin; and adding a reinforced composite geomembrane liner throughout the entire finishing basin to prevent seepage.

The power supply at the WWTP was
improved by transitioning from overhead
to buried service. There was constant
groundwater seepage and intrusion at the
Influent Pump Station (IPS). Despite this
challenge, the contractor managed the
water effectively to keep the construction
on schedule. Additionally, a new, larger
power service was provided by PG& Eat
the IPS.

APPENDIX A

CITY OF LATHROP I MCKINLEY AVENUE FORCEMAIN INTERTIE PROJECT DESIGN A

PROJECT UNDERSTANDING
The construction and operation of the intertie and proposed force main are essential to support Lathrop' songoing growth and the corresponding demand for improved wastewater infrastructure. Currently, the City sends an average of 1. million gallons per day ( MGD) to the MWQCF, approaching its allocated capacity of 1. 45 MGD. This project will establish a diversion system that enables wastewater flows to be redirected between the MWQCF and Lathrop' s own
CTF, enhancing system redundancy and operational flexibility.

The proposed force main intertie is planned at the intersection of McKinley Road and Vierra Road. The new main will extend west along Vierra Road within the City' sright- of- way, requiring a jack and bore crossing beneath the Union
Pacific Railroad and D' Arcy Parkway before ultimately connecting to the header at the LCTF headworks. In addition to this intertie, the existing SSI Lift Station is expected to be connected to the 16 -inch SSFM along McKinley Avenue by extending a 6 -inch SSFM south of Super Store Industries at 2400 W Louise Avenue. Furthermore, a new force main may be extended from the 6 -inch SSFM along Shideler Parkway to the proposed 6 -inch SSFM along Yosemite Avenue to facilitate flow diversion from the LIP Lift Station as needed. The total length of the proposed force main, covering all three connections, is approximately 2, 400 linear feet.

Along with the proposed force mains and connections, a
thorough evaluation of the existing infrastructure, including force mains, pump stations, and connecting to the LCTF, is anticipated. The project will also include installing automated systems to enable remote monitoring and control of intertie operations through the City' s SCADA system.

SCOPE OF WORK
Task 1- Project Management and Administration
This task includes management of our staff and resources, providing and maintaining the project schedule and milestone timelines, reporting and monthly invoicing, ongoing coordination efforts between the design team and the City, meetings, and other work within this scope to ensure a successful project. Meetings budgeted under this task include: Kickoff meeting, Project review meeting to discuss the results of Task 3 - Basis of Design Report, Review meetings to discuss the 30%, 60%, 90% and 100% submittals.

Deliverables: Meeting agendas and minutes, assuming seven meetings, Project Schedule and milestones timeline, Invoices with Progress Reports, and Public Outreach Documents.

Task 2 — Information Collection and Review
Thorough research to obtain all available utility documents within the project area for all applicable agency and utility companies shall be conducted. A field site visit will be conducted to collect visible information of the project site. A list and map of all underground and aboveground utilities and facilities in the project areas will be prepared and utility requests will be initiated and information obtained before any field investigations are done. City data and information regarding site topography and soils will be reviewed. Topographic survey, geotechnical investigations, utility investigations through potholing and Ground Penetrating Radar ( GPR).

Assumptions: The City will obtain necessary rights - of -entry to complete field investigations and will waive or pay required encroachment permit fees.

Task 3 — Basis of Design Report
A Basis of Design Report will be prepared. The report will summarize the findings from preliminary meetings, background research, and field investigations and provide recommendations for the design of the intertie and force mains. The report aims to define the overall project goals, design intent, and the detailed design criteria for all project components, systems, and subsystems. The report will include relevant field collection data, an assessment of the physical attributes of the existing system and infrastructure, provide limitations/ obstacles, existing capacity, design flow rate, surge pressure needs and velocity for design flow, pump and system curves for operating pressures and velocity, potential sources of connection for SSI and Shideler Parkway Development, a site layout determination, an opinion of probable construction cost, and identification of permit requirements for implementing the Project.

Deliverables: Draft Basis of Design Report, Final Basis of Design Report in PDF format.

Task 4 — Plans, Specifications, and Estimates
