Phoenix is advancing the 1A rehabilitation at the 91st Avenue Wastewater Treatment Plant, listed under District 7 as part of the Sub-Regional Operating Group. Council members took up two contract changes for the project: one for engineering services and one for construction manager at risk construction services.

Scottsdale would take a grant of up to $377,676 from the Maricopa Association of Governments to buy a new PM-10 certified street sweeper. Phoenix also would retain on-call engineering services for the Water Services Department's computer control systems.

Phoenix also would award contracts for centrifuge equipment maintenance and for membrane diffusers. In Mesa, a council committee heard a plan to raise water and wastewater rates starting January 1, 2027, including a 4% bump to the monthly water service charge and a 7.5% increase for residential wastewater.

Other items filled out the week. Phoenix would accept drainage easements in Districts 1 and 5, and amend a heat-relief contract with UMOM New Day Centers. Scottsdale would fill one open seat on its Environmental Advisory Commission as part of a larger round of board and commission picks. Tempe's council agenda included an update on the Revitalization of Tempe Town Lake Council Subcommittee, and the city's Aviation Commission was set to discuss aircraft fuel dumping incidents. Together, the week was mostly about keeping the region's water and wastewater systems running — the plants, pipes, and money behind them.
