Request service Call (832) 530-5945

Northwest Harris County has more aerobic systems than most people expect. Between the big master-planned subdivisions, which are usually on MUD sewer, there are blocks of one- to five-acre lots along Mueschke, Telge, Hufsmith-Kohrville and Katy-Hockley that rely on on-site systems.

Harris County holds residential aerobic systems to a stricter schedule than the rest of the state. Your Greywater contract here includes four inspections a year, one every three months.

Harris County questions

Why does Harris County need four inspections a year instead of three?

The state sets a minimum of one inspection every four months. Harris County sets a stricter rule for residential aerobic systems: one every three months. Our Harris County contracts are built around that quarterly schedule.

My mailing address says Tomball or Spring. Am I in Harris County?

Maybe. Spring Creek is the line between Harris and Montgomery counties, and both the Tomball and Spring ZIP codes cross it. Your OSSF permit shows which county issued it. Send us your address and we'll confirm before we set up your contract.
