LOCKPORT TOWNSHIP WATER SYSTEM Water System

Inactive system

This water system is marked inactive in EPA’s federal records as of August 15, 2024. It is no longer an operating public water system under this PWSID, and no compliance deadlines — including the 2027 Consumer Confidence Report rule — apply to it.

If you are a resident looking for your current water provider, see water systems in Will County, IL.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Illinois’s official records. Always confirm current status with Illinois before making decisions based on this information.

System facts

System ID (PWSID): IL1978100
System type: Community Water System
Population served: 2,610
Service connections: 901
Ownership: local government
Water source: groundwater (wells)

LOCKPORT TOWNSHIP WATER SYSTEM is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, formerly serving 2,610 people from groundwater.

EPA's federal records list this system as inactive in 2024; the record below is historical.

As of August 1, 2026, its federal record holds 130 entries between 1991 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

Of the 130, 124 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves volatile organic chemicals, synthetic organic chemicals, and the Total Coliform Rules.
