City of Andrews, TX

Wastewater Collection and Treatment

The City of Andrews owns and operates all of the wastewater collection and treatment systems within the city.  Sanitary sewer collection systems are designed to collect and transport sewage and industrial wastewater to a wastewater treatment facility for appropriate treatment.

Wastewater operators are required to hold treatment certifications from the Texas Commission on Environmental Quality (TCEQ) and maintain high standards for operation and maintenance.

If you suspect a sewer drain clog in your main yard line, stop any usage of your home's plumbing until the clog is removed! 

The most common sign of a sewer clog is the back up of multiple fixtures in your home at the same time. Typically, you will notice it first with your toilets, since they have a direct path to the sewer; however, you may also notice it with your bathtubs and showers since they sit lower than any sink or other fixtures in your home. Other common signs of a sewer stoppage or clog could be water coming up in the tub or shower when you flush your toilet, or when running your washing machine, your toilets will fill and overflow.

If your home has a sewer clean out, remove the cap for a visual inspection. If water is visible, overflowing or standing, you definitely have a problem.   It will be necessary to determine if it is a simple drain clog, your yard line or the City's main line that is the problem.

Reclamation Plant
The Reclamation Plant is located on County Road 1 just east of Andrews. The plant receives up to 1,100,000 gallons per day of wastewater generated from residential and commercial facilities.

The City of Andrews Wastewater Permit contains effluent limits as well as reporting, record keeping, monitoring, testing, and post-treatment requirements.

Wastewater enters the treatment plant through the City's main line, which is designed and built to collect and convey wastewater from homes, businesses and industries.

In order to properly convey wastewater, the collection system is designed for a gravity flow of two feet per second to keep solids suspended in the wastewater.  Lift Stations are used where gravity flow is not possible due to the topography of the land.  Here in Andrews, five (5) lift stations are utilized.


Odor Control
Odors occur is a natural part of the treatment of wastewater. By design, odors are usually contained within the plant site; however, due to a variety of operating and weather conditions, odors will occasionally drift away from the facility.

Most of the odors detected at a wastewater treatment plant have a rotten egg smell that indicates the presence of sulfur and may include hydrogen sulfide and mercaptans. Other odors are characterized as fishy or pungent and may include materials containing ammonia. All of these compounds are naturally occurring and are detectable by the human nose at extremely low concentrations.
