Title
Consider and take action on a resolution authorizing a one-year agreement with Republic Services, Inc. for grit screening/sludge transportation and disposal services in an amount not to exceed $439,940 (Director of Public Works)
Background:
Approval of this resolution will award the Invitation to Bid (ITB) #19-PW-019 to Republic Services, Inc. for grit screening/sludge transportation and disposal for all wastewater treatment plants. De-watering biosolids in wastewater treatment is vital in maintaining the correct balance of biomass in the secondary treatment process.
Presently, the City’s two activated sludge wastewater plants produce an annual yield of approximately 1892 dry tons/648 loads of de-watered sludge cake at 17 to 24 percent (%) solids content.
