AI Contract Overview

The City of Portola Water Distribution System and Wastewater Collection System Improvements Projects aim to modernize aging infrastructure to resolve critical failures in the city's water and wastewater networks. The wastewater system currently suffers from excessive inflow and infiltration, leading to manhole surcharges, spills, and state discharge violations. Simultaneously, the water distribution system is undersized and prone to leaks and breakages, which limits fire flow capacity and poses health risks due to the proximity of waterlines to sewer pipes. The project will replace aging steel and asbestos cement water mains with approximately 4,780 linear feet of 8-inch PVC and 5,050 linear feet of 6-inch PVC piping, along with 12 new fire hydrants, 107 gate valves, and 160 water service reconnections. Wastewater improvements, which may be completed in two phases based on funding, include replacing approximately 21,370 feet of 8-inch piping, 22,950 feet of 4-inch laterals with two-way cleanouts, and various lengths of 10, 12, and 15-inch piping. The scope also involves replacing 36 manholes and rehabilitating 110 others. Most work will occur within public road rights-of-way and utility easements in Portola, California. The project is categorically exempt under CEQA Guidelines and requires compliance with the State's In-Use Off-Road Diesel-Fueled Fleets Regulation. Contractors must also adhere to strict dust control measures, including speed limits on unpaved roads and regular street sweeping to remove silt and mud.

Full Description

The proposed project addresses improvements to the Citys water and wastewater infrastructure. Due to the age and condition of the Citys wastewater collection system, the City is experiencing excessive amounts of inflow and infiltration (I&I) entering the wastewater system during wet-weather periods. The I&I is causing manholes to surcharge, wastewater spills, and the need for emergency pumping. In turn, the City has received multiple discharge violations from the State Water Resources Control Board. The Citys water distribution system is also old and undersized, causing the City to incur losses due to leaks and frequent breakages. The small size of existing waterlines limits maximum fire flows within parts of the City. In addition, the waterlines are located in close proximity to existing wastewater collection pipelines, potentially creating serious health risks to residents due to potential contamination. Any construction and/or rehabilitation to the Citys sewer infrastructure would most likely damage existing water distribution pipelines. The proposed project would replace aging infrastructure, reduce leaks, and provide improved fire flows for the water system, and replace aging sewer infrastructure to reduce I&I for the wastewater system. Proposed water system improvements include installing ~4,780 linear feet of new 8-inch polyvinyl chloride (PVC) water mains, ~5,050 linear feet of new 6-inch PVC piping, ~12 new fire hydrants, ~107 mainline gate valves, and reconnecting 160 water service connections to the new water mains. The existing pipes would be abandoned in place. Proposed wastewater system improvements include replacing ~1,930 feet of 15-inch piping, ~480 feet of 12-inch piping, ~150 feet of 10-inch piping, ~21,370 feet of 8-inch piping, ~22,950 feet of 4-inch laterals, including two-way cleanouts at property lines, and ~36 manholes and rehabilitate ~110 manholes. Nearly all improvements would occur in existing public road ROWs and public utility easements. Sewer and water laterals would generally be extended to private property lines.
