Water & Wastewater

The water service line inventory is part of a national effort to ensure public water systems are reducing lead exposure to their customers. The U.S. EPA requires public water systems to complete a Lead Service Line Inventory (LSL Inventory). The objective of the LSL Inventory is to determine whether there are any lead pipes in the water distribution system, including both the public and customer-owned portions of the service line.

Current Water Service Line Materials

For the following reasons, it is considered highly unlikely that the City will discover any lead service lines or connectors in its distribution system:

• The City’s inventory reported no lead in the utility-owned distribution system.
• The City’s 90th percentile lead sample results have been below 15 parts per billion

A Water Master Plan was prepared for the City of Angels water supply, treatment, distribution, and storage systems to ensure the City has adequate facilities to support future growth as defined in the adopted City of Angels 2020 General Plan. The Master Plan includes an evaluation of existing facilities; an assessment of alternate water supplies; and an identification of recommended improvement projects for the water supply, treatment, distribution, and storage systems. The study area for the Master Plan is based on the current City limits from the General Plan and does not include areas within the sphere of influence beyond the City limits.

The City’s sewer system consists of approximately 22.5 miles of gravity sewer, approximately 4.5 miles of force main, pipe ranging in size from 4 to 18 inches in diameter and five (5) sewage pump lift stations. The City provides sewer service to businesses and residents within the city. The City’s sewer system also receives some flow from one housing development consisting of 64 single family home connections located in the neighboring community of Vallecito.

The City’s water conveyance system dates back to the 1850s when miners constructed ditches to convey water from the North Fork Stanislaus River to Angels Creek. The modern-day WTP, known as the Angels Water System, was originally owned and operated by Pacific Gas and Electric (PG&E). The City acquired the system from PG&E in 1984 and has operated it since. In 2002, the City published its Water Master Plan, a planning document for water needs and infrastructure. This document covered the planning horizon of 2001 through 2015. In 2010, the City recognized that most of the proposed projects in the 2002 Master Plan had been completed or were not currently needed. As such, they issued a request for proposals for a water audit, which is to be the first step in developing the City’s next Water Master Plan.
