The Wilbarger Creek Regional Wastewater Program is a major infrastructure initiative supporting Pflugerville’s continued growth. Central to the program is a new 6.0 MGD regional wastewater treatment facility (WC RWWTF) and two new interceptors designed to divert flows away from aging lift stations and toward a more efficient, environmentally responsible regional treatment system.
As part of its role as owner’s representative, STV led a comprehensive reclaimed water feasibility study evaluating how the new facility can serve as an additional supply source to expand Pflugerville’s existing reclaimed water network. The study assessed current and future reclaimed water supply, system demands, delivery locations and opportunities for regional collaboration.
What challenges did STV address?
Pflugerville’s expanding population has placed increasing strain on its potable water resources and wastewater infrastructure. The City sought a long‑term strategy to responsibly manage wastewater flows, retire inefficient lift stations and identify sustainable sources of reclaimed water to support irrigation, municipal, and potential indirect reuse applications. This required a forward‑looking assessment of supply, demand, infrastructure needs and inter‑agency coordination.
What solutions did STV deliver?
STV quantified reclaimed water supplies from the City’s existing wastewater treatment plants and the future WC RWWTF. The team analyzed system demand projections, delivery points and distribution requirements to support long‑term reclaimed water expansion. STV also engaged neighboring water providers to evaluate regional reuse opportunities and assess the feasibility of indirect potable reuse via Lake Pflugerville, providing a technically sound, environmentally responsible roadmap for future investment.
How does this project benefit the region?
The feasibility study strengthens Pflugerville’s long‑term water resilience by identifying new reclaimed water sources, reducing reliance on potable water and lowering operational burdens associated with aging lift stations. The work supports sustainable growth, enhances environmental protection and provides the City with a framework to pursue cost‑effective, community‑focused water reuse solutions.
