Septic companies in Conroe, TX

Conroe runs a central sewer system in town, so most in-city homes are connected — but the rural edges of the city and the Lake Conroe shoreline rely on septic. Systems within 2,075 feet of Lake Conroe are permitted by the San Jacinto River Authority rather than the county, with stricter design and maintenance rules. On clay-heavy lots outside the sewer network, aerobic spray systems are common.

In and around Conroe, that spans neighborhoods like Grand Central Park, Artavia and The Woodlands Hills, and the areas near Lake Conroe and W.G. Jones State Forest.
