PROJECT OVERVIEW

In 2014, in response to new discharge permit constraints issued by the Texas Commission on Environmental Quality (TCEQ), the City of League City was informed that the outfall for the effluent line of the Dallas Salmon Wastewater Treatment Plant (DSWWTP) would need to be moved from its existing location. Due to updated copper and zinc discharge limits, the outfall would need to be moved further downstream, requiring the City to build an entirely new effluent line and outfall location.

SERVICE DETAILS

In order to relocate the effluent discharge, the City tasked our team with finding new alignments from the DSWWTP to Clear Creek and to develop the most economical solution. This resulted in the installation of 1,500 linear feet of 9’x6′ and 8’X5’ reinforced concrete boxes from the existing discharge structure at the DSWWTP to a new outfall location at the north end of N. Kansas Avenue at Clear Creek. The new outfall line required the relocation of other existing utilities in the area as well as the diversion of existing overland drainage paths. To address the existing drainage issues, approximately 670 linear feet of 10’x8′ reinforced concrete box storm sewer were placed next to the effluent line from the DSWWTP.  As construction was already necessary, the city was able to use this opportunity to revitalize N. Kansas Avenue as well.

The project required continuous collaboration throughout the design process between our team’s Water, Transportation, Hydrology & Hydraulics, and Survey Practices to successfully complete the final design.
