eHT provided planning, design and construction services for improvements to the City of Breckenridge’s 3.4 MGD surface water treatment plant (WTP). eHT designed and constructed improvements to the raw water piping, pretreatment units, clarifiers, filters, pump stations, chemical feed systems, and electrical and controls systems. The raw water piping improvements included the construction of new raw water metering stations, chemical injection points, flow control valves, and rapid mix basin improvements. Plate settler packs were added to the two clarifiers to increase the efficiency of the units while maintaining the existing sludge disposal systems. The plant utilizes two dual media filters which had recently been rehabilitated with the replacement of filter media. For this project, filter-to-waste piping was installed to increase the operational flexibility of the filters as well as the associated waste piping. Filtered water is pumped from a transfer pump station to the plant clearwell. The transfer pumps and associated discharge piping were also replaced. The existing high service pumps were improved with the installation of variable frequency drives (VFDs) for each of the pumps and one pump which was in disrepair was replaced. The project also included upgrading and expanding the chemical systems including the replacement of the chemical day tanks and chemical feed skids, as well as the replacement of the plant electrical system and supervisory control and data acquisition (SCADA) system.
