Water companies that supply La Crosse

9 public water companies list La Crosse as a place they supply. The biggest is La Crosse Waterworks, with about 53,000 people.

None of the 9 with results was above 15 at its latest test. 4 found too little lead to measure. Small ones like Coulee Manor Trailer Park supply just their own grounds or street; most of La Crosse gets its water from La Crosse Waterworks. 6 are small systems serving fewer than 500 people each, such as a mobile home park, a subdivision or a business with its own well.
