Council also approved a supplement to the city’s professional services agreement with DCS Engineering, LLC for water treatment plant engineering services, in the amount of just over $253,000. The approved services are affiliated with the city’s High Service Pumping Station expansion project, located near Wolf Pack Drive and Weiss Lane.
As per the scope of services provided by city staff, this project will help extend capacity at the city’s SWTP to roughly 2024, as well as continue to meet requirements set by the Texas Commission on Environmental Quality. The services include both bidding and construction management, as well as outline a May 16, 2021 construction close-out.
In a separate agenda item, council awarded an $85,000 supplemental professional services contract to DCS Engineering for “emergency compliance and rehabilitation work” at Pflugerville’s SWTP. The scope of services include plant flows and flow projections, Lake Pflugerville operations, water membrane trains, chemical systems and TCEQ submittals, among others. The supplement would build off the initial professional services awarded to DCS Engineering that ran from Oct. 25, 2019-Feb. 29, per city documents.
Council also approved a nearly $65,000 supplemental professional services contract to DCS Engineering for compliance and rehabilitation, with the same scope of services mentioned previously.
