RECOMMENDATION:
Recommendation
Review and provide input to staff on the proposed project approach for the three new water supply infrastructure implementation projects included in the Fiscal Year (FY) 2021-25 five-year Capital Improvement Program.
Body
SUMMARY:
There are three new water supply infrastructure implementation projects in the current Board-approved Capital Improvement Program (CIP). Staff will review these projects with Valley Water’s Capital Improvement Program Committee (CIP Committee) and receive input on the proposed project approach.
Supervisory Control and Data Acquisition (SCADA) Implementation Project (Project No. 95044002) Valley Water’s process control and SCADA systems, which serve a pivotal role in monitoring and controlling the raw water conveyance system (including reservoirs and pumping plants), treatment plants and distribution systems are aging and in need of coordinated replacement and upgrade. The SCADA Implementation Project will prepare an update to the process control systems/SCADA master plan (2011), produce detailed design and implementation standards for new projects, and recommend a coordinated suite of improvement projects (projects implementation plan).
The project will develop a 15-year SCADA Capital Improvement Program with a suite of capital improvement projects along with a Programmatic Environmental Impact Report (PEIR) for the Board’s consideration and adoption. The estimated cost of the project is $6.8 million which includes $3.3 million in consultant services expenses, along with staff resources for project engineering and key partner and stakeholder participation.
Water Treatment Plant Implementation Project (Project No. 93044001)
The infrastructure needs for the water treatment plants (WTPs) have been developed over the years through a number of planning documents focused on specific process areas, and not through an integrated master implementation plan. As a result, projects are often piecemealed for specific needs, needing frequent rebuilds or upgrades due to adjacent processes or regulatory requirements changes. The WTP Implementation Project will develop a comprehensive implementation plan forecasting over a 30-year period to identify projects to repair, replace, and/or upgrade the infrastructures at Valley Water’s four WTPs; address the increasingly stringent water quality regulations; and integrate with the recently completed Water Supply Master Plan (WSMP).
The project will develop a 30-year WTP Capital Improvement Program with a suite of capital improvement projects along with a PEIR for the Board’s consideration and adoption. The estimated cost of the project is $8.6 million which includes $6 million in consultant services expenses, along with staff resources for dedicated project management and project engineering, and for key partner and stakeholder participation.
Distribution System Implementation Project (Project No. 95044001)
Valley Water has not conducted a comprehensive evaluation of its distribution system (raw and treated water pipelines) in recent history. With the recently completed WSMP, there is a need to develop a comprehensive Distribution Systems Implementation Plan (DSMP) forecasting over a 30-year period to identify improvements to Valley Water’s raw and treated water systems based on current demands, future growth, and emergencies. The DSMP will provide significant insights, analysis tools for Valley Water’s raw and treated water distribution systems to ensure that the distribution system infrastructure is appropriately sized to accommodate new supplies as they are brought online, retailer needs, and recommend direct capital actions needed to protect existing distribution systems.
The project will develop a 30-year Distribution System Capital Improvement Program with a suite of capital improvement projects along with a PEIR for the Board’s consideration and adoption. The estimated cost of the project is $8.2 million which includes $6 million in consultant services expenses, along with staff resources for dedicated modeling analysis and evaluation, project engineering support, and for key partner and stakeholder participation.
Proposed Project Approach
Given the significant nature of these efforts to conduct a comprehensive evaluation of the treatment, distribution and the key support infrastructure, staff will be engaging consultant support to develop these master plans. Over the last several months staff have been collecting key benchmarking information from other agencies on the level of effort and approach for developing infrastructure master plans as well as gathering and cataloguing past Valley Water infrastructure and asset evaluation plans. Staff plans to use this information to develop consultant scope of services for all three projects and proceed with consultant selection during the remainder of this calendar year.
The first and key task for the project team will be to work with key stakeholders and the Board to define project goals (including but not limited to capacity, regulatory and reliability goals) that align with the WSMP. Once the goals have been established, the existing infrastructure will be evaluated against the goals and recommended projects will be identified to meet the goals. Recommended projects from all three implementation projects need to be integrated to ensure the individual implementation plans for each project and the phasing are coordinated. Conceptual designs will also be completed for the recommended projects to assist in the capital improvement program development and cost forecasting. Staff plans to engage internal and external stakeholders in the process as well as provide updates and seek policy guidance from the Board and the CIP Committee.
After the development of the recommended implementation plan, the project scope will include the completion of a comprehensive PEIR so Valley Water can swiftly move to implementing the capital projects as well be poised to seek any available grant funding.
All three implementation projects will start in FY 2021. It is anticipated that the development of the recommended capital improvement projects and the implementation plan as well as the completion of the PEIRs will take approximately three years to complete. Staff is currently preparing the request for proposals for the implementation project consultant services and plans to complete consultant selection and agreements in the spring of 2021.
