JHEC Expansion - Completed

Location:

Harkey and Magnolia

Estimated Completion Date

April 2009

Project Details

Design and construct expansion of the plant capacity from 2 MGD to 6 MGD and equip the plant to expand treatment capacity to 4 MGD (ADF). New components will include expanded lift station, piping, headworks, 4 new SBR basins sized to handle a 4Q peak flow, a new disk filter media system, two new aerobic digesters, a new solids centrifuge and sludge handling system, new blowers and associated electrical and instrumentation. The project also includes additions to administrative areas and a maintenance area, a circumferential fence and obscuring landscaping package.

Project Justification

TCEQ regulations require that cities begin their expansion design programs when plants experience flows in excess of 75% of their existing capacity for three consecutive months. The Southwest Environmental Center experienced flows exceeding 75% of its capacity in summer and fall of 2004. Previously the City had been diverting excess flows to the Barry Rose treatment plant. In accordance with TCEQ regulations and the growth rate for the service area the City determined that construction must begin by the time the facility reaches 90% of its current rated capacity.
