City of Lubbock
Construction Management & Administration
Plummer supported the City of Lubbock with planning, permitting, design and construction administration of a new wastewater treatment plant to provide additional treatment capacity to support growth. Plummer projected future flows, and a new plant was determined to be the most advantageous alternative, because it eliminated the need for costly conveyance improvements. The new plant would also provide a source for reclaimed water in an area where it was needed. Plummer assisted with site selection, and it was Master Planned for an ultimate capacity of 15 million gallons per day (mgd) with an initial phase 3 mgd facility.
Plummer provided the planning, permitting, design, and construction administration for the initial phase 3 mgd plant designed to use a Carousel treatment process with chemical phosphorus removal and MBR equipment to meet an effluent phosphorus goal of 0.1 mg/L. The treatment process included rotary drum fine screens, headcell multi-tray grit removal, flow equalization, peak flow storage, and UV disinfection. The project design included a first-in-the-US combination of surface aerator aeration basins paired with a Membrane Bioreactor system and is the largest flat sheet membrane bioreactor facility in Texas.
The new treatment facility has related projects bringing wastewater, potable water, and power to the site. Pipelines were designed to take sludge and effluent away from the site. Plummer coordinated design of the related offsite utilities and equipment preselection services included development of P&IDs, preliminary mechanical drawings, specifications, and advertisement and award support.
