Description

The City of Phoenix Water Services Department is soliciting offers for Sanitaire Membrane Diffusers for use at the 23rd Avenue and 91st Avenue Wastewater Treatment Plants.

The contractor will be responsible for providing all necessary equipment, labor, supplies, transportation, and materials for the delivery of the membrane diffusers to the specified City worksites. This includes associated hardware such as mounting brackets, gaskets, grease, seals, and connectors compatible with existing piping.
