Why is well and septic such a big deal around Conroe?

Conroe is one of the fastest-growing cities in America — the population has more than doubled since 2010, from about 56,000 to roughly 125,000 — and growth in the unincorporated county around it has been just as fast. Subdivisions, acreage tracts, and older neighborhoods outside utility-district boundaries rely on private wells drawing from the Gulf Coast Aquifer System and on septic systems (what Texas regulations call on-site sewage facilities, or OSSFs) permitted through Montgomery County Environmental Health Services.

That means tens of thousands of local households are their own water utility and their own sewer plant. When something goes wrong, it’s on the homeowner — and the difference between a $400 fix and a $15,000 one is often how early you catch it.

Frequently asked questions

How often should a septic tank be pumped in Texas?

For a typical four-person household with a 1,000-gallon tank, TCEQ’s guidance works out to pumping roughly every 2.5–3 years. Bigger households or smaller tanks need it more often. If you can’t remember the last pump-out — or you bought the house and never asked — that’s the sign to schedule one.

Do I need a permit for septic work in Montgomery County?

Yes for anything significant. New systems, tank replacement, and drain field repair or replacement all require a permit from Montgomery County Environmental Health Services (501 N. Thompson, Suite 100, Conroe). Emergency repairs that don’t involve removing the tank are exempt from permitting but must be reported to the county within 72 hours.

Do private water wells in Montgomery County need a permit?

Every well must be registered with the Lone Star Groundwater Conservation District, which manages groundwater for the county. A typical single-family home well is “exempt” — it must be registered but doesn’t need an operating permit. Your licensed driller normally handles registration and the state well report as part of the job.

Why does my well water smell like rotten eggs?

That’s almost always hydrogen sulfide gas — a common, usually harmless nuisance in Gulf Coast groundwater, sometimes made worse by the magnesium rod in your water heater. It’s treatable. Start with a water test to confirm what you’re dealing with; see our well water treatment page for options and honest cost ranges.

How much does a new septic system cost in the Conroe area?

It depends heavily on your soil and system type. Conventional systems cost less; aerobic systems with spray distribution — common here because clayey subsoils often won’t pass a percolation-style soil analysis — typically run in the five figures. National 2026 figures for aerobic systems run roughly $10,000–$20,000 installed. Get local bids; the county-required soil evaluation determines what you can build.

Is my well water safe to drink?

Private wells aren’t tested by anyone unless you do it. Texas A&M’s Texas Well Owner Network and TCEQ recommend testing at least annually for coliform bacteria, nitrate, and total dissolved solids — basic tests start around $20–$30 through certified labs. If you’ve never tested, do it before spending anything on treatment equipment.
