Evaluation and Design of Odor Abatement Improvements for New WWTP

Hutto, Texas

PECI assisted a larger team of consultants with design of a new, state of the art wastewater treatment facility to serve the City of Hutto. The plant is being built from the ground up and will be operated by the Brazos River Authority when complete.

PECI modeled odor dispersion from the plant’s major process units and assisted with selection of odor control improvements designed to keep detectable off-site odors to a minimum practical level. PECI personnel participated in a public meeting at the site and assisted in developing odor-related language for incorporation into an agreement with nearby landowners, enabling formal permit protests to be withdrawn.

PECI designed an organic media biofilter, ductwork, and a foul air collection system to serve the plant’s headworks structure and dewatering building.

The opinion of probable construction cost for odor control was $400,000. This project was bid in March 2015.
