Water, Wastewater, and Stormwater Utilities Building Climate Resilience

Water, wastewater, and stormwater utilities are central to long-term community resilience. They shape how much potable water a community uses, how effectively wastewater is treated and reused, how stormwater is managed, and how utility assets perform during heat, drought, flooding, and sea level rise. The strongest examples in the research file show that leading utilities are pairing customer-facing conservation with major operational change.

On the community side, Austin, Tucson, El Paso, and San Diego demonstrate different versions of a One Water approach. Austin links conservation planning with reclaimed-water and onsite-reuse requirements. Tucson combines a large reclaimed-water network with rebates for turf removal, rainwater harvesting, graywater, and efficient fixtures. El Paso pairs long-standing conservation rules and pricing with advanced water-reuse and supply diversification. San Diego’s Pure Water program shows how treated wastewater can become a major local drinking-water source. Philadelphia and Portland show that stormwater programs are strongest when green infrastructure is treated as core infrastructure rather than decorative landscaping.

The operational examples are equally important. DC Water’s thermal hydrolysis, digestion, and power generation system shows how wastewater solids can become an energy resource. St. Cloud turned its wastewater facility into a nutrient, energy, and water recovery center. San Diego operates major utility facilities with a diversified renewable-energy portfolio. Appleton and Boulder show how targeted plant investments can drive large emissions and cost reductions. Seattle and Santa Barbara are strong adaptation examples because they explicitly plan for hotter conditions, shifting hydrology, flooding, and sea level rise at the utility-asset level.

For a typical utility department, the most transferable package would combine long-range conservation planning, stronger reuse programs, a stormwater strategy that keeps runoff out of sewer systems, treatment-plant energy and resource recovery, and asset-specific climate adaptation planning. Utilities are already managing essential systems. The next step is making those systems lower-emission, more efficient, and more climate ready.
