Program Overview

OCWA—Central New York’s Water Authority— is committed to combating lead in drinking water by identifying the type of materials used to construct all customer water service lines throughout our five-county territory. This effort is being made in conjunction with the U.S. Environmental Protection Agency’s (EPA) revised “Lead and Copper Rule” requiring public water systems nationwide to create an initial service line inventory by October 16, 2024. In addition, under the recently proposed “Lead and Copper Rule Improvements” (LCRI), all water systems would be required to regularly update their inventories, create a publicly available service line replacement plan, and identify the materials of all service lines of unknown material.

Lead in drinking source water is relatively rare, and OCWA continuously takes multiple proactive steps to prevent lead from entering our water system. However, lead can enter tap water when home or business plumbing materials containing lead corrode.

It is important to understand that ownership of water service lines is shared between homeowners and OCWA. OCWA owns the portion of the water service line from the water main to the shutoff valve located at the property line. Customers are responsible for the portion of the service line from the outlet side of the shutoff valve to the water meter or main shutoff valve inside their home, as well as their home’s internal plumbing and fixtures.

Service Line Map


To help OCWA identify all customer service lines, we encourage you to utilize the resources provided below to determine if you have a lead service line. Please take a few moments to identify the service line materials in your home and report the information to OCWA. Your cooperation will help ensure accurate updates to our service line material inventory as we plan future lead service line replacement initiatives throughout our community.

Thank you for your participation!
