Drive north on FM 1774 out of Magnolia and the lots get bigger fast. Southern Grimes County is pasture, horse property and homes on 10 acres or more, nearly all of them on septic, and many of them aerobic.

We service the southern and eastern parts of the county, the areas closest to Magnolia and Montgomery. Call us with your address if you're farther north.

Grimes County questions

Is Plantersville too far out for you?

No. Plantersville and Todd Mission are a short drive up FM 1774 from Magnolia, and they're part of our regular service area.

I have a big spray field on acreage. Does that change maintenance?

The system works the same way, but long spray lines and more spray heads mean more places for a break or clog. We check every head against your county installation drawing during inspections and repairs.
