Recognized as an industry leader in water treatment, Plummer has in-depth experience bringing existing facilities to compliance as well as designing new facilities to meet current and anticipated requirements. We have a thorough understanding of water quality issues including total organic carbon, inorganic constituents (iron, manganese, etc.), disinfection by product precursors, and taste and odor, and we work with our clients to design facilities that address these issues. Whether designing a facility with a total capacity of less than 1 million gallons per day (MGD), or a plant capable of treating over 800 MGD, our engineers and designers collaborate to select processes and technologies that make the most sense.
We have experience with direct, conventional, and membrane facilities. We have designed systems including but not limited to the following: pre-oxidation, including ozone, chlorine dioxide, potassium permanganate, and powder activated carbon; pretreatment, including horizontal and vertical shaft flocculation, circular and rectangular (high rate) sedimentation basins, and solids contact processes; filtration, including dual and multi-media, microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. Our disinfection process experience includes gaseous chlorine, bulk and onsite generation of sodium hypochlorite, and chloramines. Our team also has extensive experience in pre and post-treatment chemical storage and feed system design, backwash treatment and recycle systems, high service pump stations, and potable water storage facilities. No matter what treatment process we are implementing, or technology and equipment type we are selecting, we deliver facilities that transform our clients’ futures.
With a background in civil engineering, Patrick has worked on water projects ranging from conventional design-bid-build to multidiscipline design-build projects serving as principal-in-charge, project manager, project engineer, and construction manager.
His most notable experience includes serving as Principal-in-Charge for the Elbert Creek Water Company Water Treatment Plant which was the first gravity operational mode membrane filtration plant in Colorado; leading successful teams for prominent clients including Denver Water, Upper Trinity Regional Water District, and City of Dallas; and designing approximately 25 water treatment plants across the region.
Phase 1 design capacity is 1.5 MGD with planning and design provisions for a future Phase 2 expansion to 5 MGD.
This project, which received a 2020 American Council of Engineering Companies Colorado Honor Award, included the first gravity operational mode membrane filtration system in the state of Colorado.
Plummer has worked with the City for over 20 years to evaluate, plan, and design facilities that have allowed the WTP to keep ahead of the rapidly increasing water demands.
Plummer designed a new 20 million gallons per day (mgd) microfiltration membrane water treatment plant (WTP) shared by the City of Waxahachie and Rockett Special Utility District.
Plummer conducted an in-depth evaluation of process, mechanical and electrical equipment, and Laboratory and Administrative Building facilities.
We design solutions for the world’s greatest water and telecommunications challenges. We are ready to take on issues you face today so you are better positioned for tomorrow.
