Service Line Inspections 

The City of Brentwood has completed the initial lead service line inventory required by U.S. EPA’s Lead and Copper Rule Revisions. The deadline for the initial inventories is October 16, 2024.

Through completing a historical records review and field investigations, the City of Brentwood has determined it has no lead service lines, galvanized requiring replacement service lines, or lead status unknown service lines in its distribution system. This includes any privately-owned or customer-owned service lines.

The City of Brentwood reviewed all applicable sources of information, including

• All construction and plumbing codes, permits, and existing records or other documentation which indicates the service line materials;
• All water system records, including distribution system maps and drawings, historical records on each service connection, meter installation records, historical capital improvement or master plans, and standard operating procedures;
• All inspections and records of the distribution system that indicate service line material, including inspections conducted during the course of normal operations (e.g., checking service line materials when replacing water meters or performing maintenance activities);

In addition to reviewing the above sources of information, the City of Brentwood inspected all service lines of its distribution system, regardless of ownership. All service lines were verified non-lead.

Details on Service Line Inspection Project 

The U.S. EPA’s Lead and Copper Rule Revisions (LCRR) require all community water systems (CWS) to develop and submit an inventory of service line materials connected to the distribution system to the Division of Drinking Water (DDW) by October 16, 2024.

The water delivered by the City of Brentwood to customers is lead-free. And for decades, Brentwood has protected its customers from the effects of lead-containing water by installing service lines made of type “K” copper and distribution system consisting of PVC, cast iron and steel. The City of Brentwood has optimized corrosion control treatment techniques to help reduce the corrosivity of the water, which helps protect customers from lead exposure from pipes, fixtures or solder.

Starting in 2023, the City of Brentwood began developing an inventory of service line material which includes both Brentwood-owned and customer-owned portions of the service line. Water Distribution staff physically inspected service lines of homes built before 1986, by utilizing a geographic information system (GIS) to categorize service lines as; lead, galvanized requiring replacement, non-lead, and lead status unknown.
