Project Overview

The Pecan Creek Water Reclamation Plant was originally built in 1961 and has undergone multiple expansions and repairs while serving the City of Denton, Texas. Sitting in the north of the Dallas-Fort Worth Metroplex, the city’s growth in population has pushed the 21 million gallon per day (MGD) plant to almost 90% capacity. After initial plans called for expanding the existing facility, Sundt helped the City of Denton plan for a long-term solution and build a new 30 MGD membrane bioreactor facility to replace the aging plant.

The new Pecan Creek Water Reclamation Plant sits next to the existing plant. It includes a 75 MGD headworks, a full membrane bioreactor (MBR) system, ultraviolet disinfection, non-potable water storage and reuse capacity, anaerobic digesters, and expanded solids handling. In addition to the construction of these treatment structures and capabilities, the project also includes the construction of a 17,000-square-foot Control Operations Building which includes office space, electrical/I&C/maintenance shops, a laboratory, and the Operations Control Center/SCADA room. The site also includes a total of 30 million gallons of lined pond volume for detention of wastewater.

Biosolids generated by the treatment process are upcycled on-property and beneficially reused in compost, soil blend, and mulch products sold by the City of Denton. Biogas generated by the treatment process will be captured and sent for cleaning, after which it can be used as natural gas for heating and other purposes.
