Where Colorado's small water systems are
226 community water systems — 146 positioned, 80 awaiting a mapped service area.
- Community water system (estimated position)
- Verified well
135 system positions come from EPA-modeled service areas (estimates); 11 come from service areas on file with EPA (submitted by the system or state, not modeled) — neither is a legal boundary. Verified wells are matched to Colorado DWR well-permit records; plotted locations are approximate — most records place wells by land-survey section, not GPS.
Not yet positioned
These 80 systems have no service-area boundary on file with EPA to draw a position from yet — no guessing at a town center.

Positions are the calculated center of each system's service-area boundary on file with EPA (retrieved 2026-08-06) — a center standing in for the whole area, not a legal boundary or a verified address. 135 of 146 come from an EPA-modeled boundary (a statistical estimate); 11 come from a boundary the system or state itself submitted to EPA (not modeled by EPA, but likewise not a legal boundary). Systems with no boundary on file appear in the list above instead of a guessed pin. Verified well locations come from Colorado Division of Water Resources well-permit records — plotted positions are approximate, since most records place a well by land-survey section rather than GPS — and also appear on each system's own page.
