Utility Line Maintenance



Effective March 1, 2013, the City of Lewisville will no longer provide cleaning of residential sewer service lines.

If you have a sewer stoppage on or after March 1, 2013, you will need to contact a plumber or other service provider. There are also a number of warranty programs and vendors that provide water and sewer service line warranties. These warranties usually cover maintenance and repair costs on the water and sewer service lines for a small monthly or annual fee. This may be a desirable alternative for you if you want to insure against unexpected repair or cleaning costs.
The Utility Line Maintenance Division is dedicated primarily to the maintenance and repair of water and sewer mains.

Descriptions of common problems and helpful tips

  • Main Breaks: If you notice water coming up from the cracks in the street or sidewalk, there may be a main break. Please call the Utility Line Maintenance Division 972.219.3510 as soon as possible. Your assistance in the early detection of these leaks is greatly appreciated.
  • Low Water Pressure: If you are experiencing low water pressure there are a few things that you can check. First, if you have a water filtration system, check to see if the filters are clean. If you do not have a filtration system, check the faucet screens to be sure that they are not clogged. If the low pressure is only on the hot water, this may indicated a problem with the hot water heater. If the low pressure is only in certain areas of the house, this may indicate an internal problem. Otherwise, there may be a problem with the pressure from the City line. Please call the Public Works Department at 972.219.3510 and a crew will be dispatched.
  • Sanitary Sewer Overflow: The sanitary sewer system transports sewage throughout the service area to the City of Lewisville’s Wastewater Treatment Plant. Sanitary sewer systems that are properly designed, operated and maintained collect and transport all of the sewage and industrial wastewater that flow into them. Sanitary sewer overflows (SSOs) are a type of unauthorized discharge of untreated or partially treated wastewater from the collection system or its components, (such as manholes, lift stations, or cleanouts) before it reaches the Wastewater Treatment Plant. These overflows are potentially harmful to human health, safety and/or to the environment. There are many contributing factors and causes of sanitary sewer overflows, such as the overloading of the collection system due to significant Inflow/Infiltration (I/I) in the collection system. This may be due to undersized or damaged infrastructure such as pipes and lift stations in the collection system which can not keep up with incoming flows due to increased system demand on the sanitary sewer from storm water that infiltrates the sanitary sewer system. Sanitary sewer system overflows may also be caused by inadequate capacity of the collection, storage or treatment system, which if undersized cannot keep up with the incoming flow into the system. Sanitary sewer system overflows may also be caused by operational and maintenance failures. The sanitary sewer system is the collection of all waste that is disposed into it. Frequently, the City of Lewisville’s Utility Line Maintenance Division must work to remove items from the collection system that are harmful or do not belong there. The majority of these sewer problems start as poor practices inside homes, apartments, businesses, such as food establishments, or construction sites. Items such as trashdebris,hazardous chemicals, or grease cause line stoppages or damage to the sanitary sewer system. Sewer stoppages often lead to sewer backups into homes and business and can cause sanitary sewer overflows. Click on the links above to find ways that you can help protect your sewer line.
