Engineering, architecture, construction, environmental and consulting firm Burns & McDonnell was selected to deliver a new $80 million 2-million-gal.-per-day water reclamation facility for the city of San Marcos, Texas.
The facility will help manage increasing wastewater demands from rapid residential development and meet an accelerated timeline driven by continued growth in the region.
"We're proud to help San Marcos meet its critical wastewater infrastructure needs," said Sarah Isbell, leader of the Water Group of Burns & McDonnell in Texas. "Our progressive design-build approach gives us the ability to collaborate early, make informed decisions and accelerate delivery — all while keeping the city's priorities front and center."
Engineering began in July 2025, and completion is expected by the end of 2026, according to sanmarcorecord.com. Construction is anticipated to start in January of 2026 with a substantial completion date of August 2028.
The city has entered into a cost-sharing agreement with several residential developers to provide a centralized wastewater treatment facility to support their planned homebuilding schedule. As part of the agreement, the city has committed to providing wastewater service to developers as new homes are occupied, in advance of the permanent water reclamation facility completion.
To support the city in meeting the commitment, Burns & McDonnell will implement a fast-tracked interim wastewater management system while concurrently designing the permanent facility. The firm's integrated team brings the ability to manage both phases under a single contract, providing continuity, speed and cost efficiency.
"Having a forward-looking project that meets the needs of developers who are participating in a cost-sharing agreement and for the area's high growth potential, it is essential that we have the right team to execute the design and construction of this facility," said Tyler Hjorth, director of utilities for the city of San Marcos. "Burns & McDonnell is the perfect fit for us to meet schedule, budget and the innovation we are looking for. We are truly looking forward to this partnership delivering a world-class project that will meet our immediate and long-range needs."
The new facility is part of the city's broader plan to accommodate population growth while protecting public health and the environment.
"This project exemplifies the value of experience, regional knowledge and integrated delivery," Isbell says. "We're excited to bring the full strength of our team to a community that's shaping the future of Central Texas."
