Last month, Freese and Nichols attended the annual Water Reuse in Texas conference in Houston. David Jackson, P.E., BCEE, Water/Wastewater Treatment Group Manager, presented an update on the City of Cleburne’s water reuse program. Freese and Nichols has assisted the City with the development of their reuse program since its inception in 1997 and was recently selected to help with expansion of the program to provide additional industrial supply and indirect potable reuse.

Key points from the presentation:

  • The City’s reuse program currently provides reclaimed water from its only wastewater treatment plant to a major industrial customer and a recreational sports complex for irrigation.
  • Population has increased by 30 percent and is projected to triple by 2050. The industrial base has increased its water demand by 1,000 percent and is projected to double due to the City’s relation to the Highway 121 toll road. This higher demand on available water resources has created a need for new water resource facilities and an expanded water reuse system.
  • Current planning for the reuse program includes system capacity and delivery expansion, stakeholder coordination, water quality evaluations, regulatory impacts, reuse treatment facility alternatives, and the reuse distribution model development. Additionally, a reclaimed water storage tank and pump station are planned to increase the flexibility of matching water supply and demand.
  • A new reuse integration plan is being developed to allow the City to determine the cost/benefits, rate impacts, and develop a phased implementation schedule to reduce rate impacts to customers.

The expansion of the reuse system will allow the City to augment their Lake Pat Cleburne raw water supply, which supplies the City’s potable water treatment facility. A key step was the careful consideration of discharging effluent directly to the lake to avoid undesirable long-term changes to the reservoir water quality. This includes not only the management of nutrients for dissolved oxygen levels, taste and odor issues, and other degraded aesthetic water quality, but also understanding the potential impacts of recycling the water on TDS and water quality in the reservoir.

Freese and Nichols is experienced in planning and designing water reuse programs for a number of municipalities and organizations. To discuss how to implement your own program or reuse practices, contact David Jackson at David.Jackson@freese.com.
