Simsboro Aquifer Water Treatment Plant, Well Field Collection Piping

The deadline to ask questions is 2/16/2023 3:00 PM CST Question Deadline has been extended to 3/2/23 at 3:00 pm The City of Bastrop is in the process of converting its water supply source from shallow alluvial wells primarily fed by the Colorado River to deep wells that draw from the Simsboro Aquifer; which will provide the City with a reliable, resilient, drinking water supply. THIS PACKAGE SPECIFICALLY contains the scope of work needed for the pipeline(s) from the well field to the WTP. The entirety of the project consists of the following: A new well field and production facilities Three additional wells are needed to meet Phase 1 flows, which consist of an average production capacity of 3 MGD and a peak capacity of 6 MGD. Water collection piping and access roads will be installed to each of the new wells. Groundwater treatment facilities Based on water quality sampling, a WTP primarily focusing on iron and manganese removal is needed. It will consist of chemical addition facilities housed in a chemical building and gravity filters housed in a filter building. Low Lift pump station Once treated, water will be pumped from the filter effluent to a 0.5 MG clearwell through the Low Lift pump station Ground Storage Tank (clearwell) Backwash pump station Backwash pumps will pull water from the clearwell and send it through the treatment plant to clean the filters Transmission piping - water will be conveyed through the 24-inch diameter, 21,500 lf transmission pipeline to GSTs at the Willow Site. Lift Station and Force Main A 21,500 lf wastewater forcemain will run along the same route as the transmission pipeline to convey wastewater generated during filter backwash and in the Filter Building to the City's wastewater collection system. Associated services Electrical and instrumentation Site development and access Various site improvements, paving, grading, fencing, landscaping.
