Lake Houston, Crosby and Dayton, Texas

Septic Service and Plumbing Around Lake Houston, TX

One call reaches an independent licensed pro who pumps the tank, finds what is wrong with the drain field, sets a new system, or sends a camera down the sewer line. The county permit rules are laid out here too, because the county you live in decides what has to happen before a shovel moves.

Serving Huffman, Crosby, Dayton, New Caney, Porter, Atascocita, Humble and Kingwood. The work is the pro’s, under his own license.

Two trades, one phone line

Septic First, Plumbing When the Pipe Is the Problem

Septic. Acreage and older-subdivision lots around Huffman, Crosby, Dayton, New Caney and Porter run their own wastewater. The jobs are pumping, finding out why a field is soggy, replacing a broken distribution box or baffle, installing a new system on a lot with no sewer, and the scheduled visits an aerobic unit needs.

Start at the septic page, or go straight to pumping, repair, a new system or aerobic service.

Plumbing. Houses on a district’s sewer, in Atascocita, Humble and Kingwood and plenty of newer streets farther out, still have drains that back up, water heaters in the garage and supply lines under the slab. A plumber who also handles septic is the same phone call whichever pipe it turns out to be.

Start at the plumbing page, or go to sewer line and drains, water heaters or slab and pipe leaks.

Septic or sewer

Find Out Which One You Have Before You Call Anyone

A surprising number of people in this area are not sure. The tell is usually a lid in the yard, a monthly sewer line on a utility bill, or a notice from the district that supplies water. The county’s permit records can show a system on file. Texas does not require a seller to have a septic system inspected before closing, so a buyer may be the first person to ask.

The septic-or-sewer page sets out the checks in the order that costs least.

Common questions

Before You Call

Who does the actual work?

An independent pro who holds the license the job calls for: a plumber under a Texas State Board of Plumbing Examiners license for plumbing, and for septic work an installer or maintenance provider licensed or registered with the Texas Commission on Environmental Quality. This site answers the phone and the form and passes the details to him. The inspection, the price, the permit and the work are his, and the contract is between you and him.

Do I have a septic system or city sewer?

Look for a round or rectangular lid in the yard, check whether you pay a monthly sewer charge on a utility bill, and ask the district or city that supplies your water. Around Lake Houston some streets are on a district's sewer and others, especially the acreage lots toward Huffman, Crosby, Dayton, New Caney and Porter, are on septic. The septic-or-sewer page walks through how to tell.

Who permits a septic system here?

The county, and the county depends on where the lot sits. Harris County's Office of the County Engineer permits systems on unincorporated Harris County property outside public sewer; Montgomery County Environmental Health Services in Conroe covers New Caney and Porter; Dayton is in Liberty County, whose rules this site has not read. The permits page sets out what each county's own pages say.

How often should a septic tank be pumped?

The sources disagree a little, which is honest. Harris County's page says every two to three years; the Texas Commission on Environmental Quality says every three to five years for a conventional tank and, for aerobic units, by sludge depth and the manufacturer's advice. Household size, tank size and a garbage disposal all push the interval, and the pro who opens the lid can tell you.

Does an aerobic system need a maintenance contract?

TCEQ's maintenance page says aerobic treatment systems are maintained by a licensed maintenance provider, with a report at least once every four months, or every six months if the unit has an electronic monitor. The aerobic service page explains what the visits cover and what is left to the owner.

All questions

Soggy yard, gurgling drains, or a lid you have never opened?

Call and describe it. The pro looks first and quotes after, and nothing obliges you to hire.
