WESTWARD HO TRAILER COURT Water System

Inactive system

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

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026.

System type: Community Water System
Population served: 50
Service connections: 17
Ownership: privately owned
Water source: groundwater (wells)

WESTWARD HO TRAILER COURT is one of 583 community water systems in South Dakota in the 500 or fewer people size category, formerly serving 50 people from groundwater.

EPA's federal records list this system as inactive in 2000; the record below is historical.

As of August 1, 2026, its federal record holds 79 entries between 1993 and 1999, all of which EPA lists as closed. Nothing has been added since 1999.

Of the 79, 67 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 synthetic organic chemicals, volatile organic chemicals, and the Total Coliform Rules.
