Reading Summary: Water Management Plans Project Reliable Water Supplies Through 2050

Key Facts

Rowland Water District (RWD) Board unanimously adopted the 2025 Regional Urban Water Management Plan (RUWMP) and companion Water Shortage Contingency Plan (WSCP) following a May 19 public hearing
The RUWMP formally found that the region has adequate and reliable water supplies to meet projected demands through 2050, even under extended drought conditions
The WSCP defines six progressively stricter shortage levels, ranging from up to 10% shortage to greater than 50% shortage, each with specific conservation measures and restrictions
RWD partnered with Three Valleys Municipal Water District and six other retail agencies to develop the plan regionally, splitting costs to reduce ratepayer impact
State law requires urban water management plans every five years, projecting 25 years ahead

Who Is Affected

Rowland Water District customers in Rowland Heights
Three Valleys Municipal Water District and six unnamed retail partner agencies
Residential and business customers relying on the regional water supply portfolio

Policy/Legal Angle

Plan is mandated under California’s Urban Water Management Planning Act (requires updates every five years)
The companion Water Shortage Contingency Plan is a separate state requirement
Plans must account for climate change and regulatory requirements — signaling alignment with broader state climate adaptation mandates

Blog Angles

Regional collaboration as a cost model: RWD split planning costs across eight agencies — is this becoming a best practice statewide, and which districts are still going it alone at higher ratepayer expense?
What’s inside the six shortage tiers?: The WSCP’s graduated response levels (10% to 50%+) are rarely scrutinized publicly — what specific restrictions kick in at each stage, and how do they compare to neighboring districts’ plans?
Testing the “reliable through 2050” claim: The finding of reliability “even under extended drought” deserves examination — what assumptions about imported water, groundwater, and recycled water underpin that projection given accelerating climate uncertainty?

ROWLAND HEIGHTS – Following a public hearing on May 19, the Rowland Water District (RWD) Board of Directors voted unanimously to adopt the 2025 Regional Urban Water Management Plan (RUWMP) and its companion Water Shortage Contingency Plan (WSCP), demonstrating how the District will manage available water sources to meet both current and future customer needs.

State regulators require water providers to develop urban water management plans every five years. The process looks 25 years ahead, weighing climate change, population growth, conservation and infrastructure investments against projected demand under both average conditions and extreme drought. The effort confirms the long-term reliability of RWD’s supplies.

The WSCP, also required by the state, sets out how RWD would respond if a drought, regulatory cutback or other event temporarily reduced available supplies. It defines six progressively stricter shortage levels, from a shortage of up to 10% to a shortage greater than 50%, each with specific conservation measures, water-use restrictions and supply actions. The plans together provide a long-range view of water supplies and a defined response for short-term shortages.

Formally, the 2025 RUWMP reached important findings including that “the region has adequate and reliable water supplies to meet projected demands through 2050, even under extended drought conditions”; and that the region “is well positioned to adapt to future challenges, including climate change and regulatory requirements, while maintaining reliable water service for residents and businesses.”

“Our customers can rest easy, knowing that when they turn on their faucets, water will be there,” said RWD General Manager Tom Coleman. “By diversifying our water portfolio, carefully managing resources and collaborating with our regional partners, we are confident that water will be here to serve local families and businesses for many years to come.”

RWD partnered with Three Valleys Municipal Water District and six other retail agencies to develop the RUWMP. By working together on a regional plan, RWD was able to split costs with the other agencies, thereby reducing the impact on ratepayers.
