Title
Consider and take action on a resolution authorizing an agreement with Alvin Contracting for the repair of Riser No. 6 at the Dallas Salmon Wastewater Treatment Plant (DSWWTP) Lift Station in an amount not to exceed $55,000 (Director of Public Works)
Background:
Approval of this resolution will authorize an agreement with Alvin Contracting for the repair of Riser No. 6 at DSWWTP Lift Station in an amount not to exceed $55,000.
The subject ductile iron pipe riser is one of six risers in the DSWWTP influent lift station that conveys wastewater from the collection system through the treatment plant process. These risers have been in service since 2006 and are subject to a highly corrosive atmosphere. All efforts to control leaks on this riser were exhausted due to extreme corrosion. The riser repair is considered urgent in order to maintain full pumping capacity during extreme weather events. A lift station rehabilitation Capital Improvement Project is scheduled in the near future to address all riser pipes and other wet well related issues. This lift station serves approximately 80 percent of the City’s current wastewater collection service area and must be maintained to optimal service performance to ensure regulatory compliance.
