Little Fossil Creek Sewer Interceptor Improvements

  • Project typeWater and Wastewater Improvements
  • Project value$10,038,393.00
Water & Sanitary Sewer Imrpovements

Existing sanitary sewer interceptors will be replaced in four project areas that impact Fort Worth Council District 11, Haltom City and Blue Mound.

Map 1 is in Haltom City. 

  • The line parallels Little Fossil Creek from just south of Broadway Avenue in Haltom City to north of East Long Avenue in Fort Worth.
  • The existing cement sewer interceptor is 27-inches in diameter.
  • Construction may impact customers in the Bonnie Brae neighborhood association.

Map 2 is in Blue Mound, north and west of Council District 2. It extends northwesterly from the Blue Mound/Fort Worth city line – just south of Independence Road – to S Blue Mound Road.

  • The existing concrete sewer interceptor is 18-inches in diameter.

Map 3 is in Fort Worth Council District 11 and Haltom City. The sewer interceptor runs through industrial and commercial areas from Thomas Road at Orval Court to Elliott Reeder Road. The interceptor crosses Airport Freeway and the TRE.

  • These concrete sewer interceptor mains range from 36-inches in diameter to 48-inches in diameter.

Map 4 is in Council District 2. It extends from Thomas Road at Lower Birdville Road to Thomas Road at Orval Court.

  • The existing concrete sewer interceptor is 36-inches in diameter.


Also included in this capital improvement project is converting a City of Fort Worth meter station to solar power and updating the structural design of the meter station.

  • The meter station is in Council District 11.
  • Construction could impact customers in the Garden of Eden neighborhood association and Neighborhoods of East Fort Worth neighborhood association.


An interceptor sewer is a major sewer line that receives flows from trunk sewer lines and smaller sewer mains. This combined flow is then directed to a wastewater treatment facility or another interceptor.  

In a typical sewer system, sewage first flows from domestic buildings via relatively small pipelines known as laterals. These pipelines take wastewater from residential/private properties and direct it to government-owned local sewer lines that run under streets and other rights-of-way, or in easements. Local sewer lines then discharge the wastewater via gravity to trunk sewers located at various manhole locations.

Interceptor sewers then take the contents of the trunk sewers, directing them to an appropriate treatment facility. Since interceptor sewers take collective flows from laterals, local lines, and trunk sewers, they are among the largest pipes in a sewer network. Some interceptor sewer lines can be more than eight feet (96-inches) in diameter and convey millions of gallons of wastewater per day. Interceptor sewers are also known as interceptors.
