It’s difficult to imagine a future without water. But were it not for continual careful planning, engineering and management of this most vital resource, there would be little of it to speak of in semi-arid Pasadena, much less the thriving economic and cultural center we are fortunate to call the “Rose City.”

With so much concern about current shortfalls in supply, and predictions of long-term drought, PWP has crafted its most comprehensive water resource plan ever. The Water Integrated Resources Plan (WIRP) of 2011 is our city’s blueprint for ensuring reliable, cost-effective, and environmentally responsible water supply for the next twenty-five years. It takes into consideration available and alternative supplies, demand forecasts, climate change and conservation.

UPDATE! WIRP 2011 Approved By City Council

Pasadena City Council approved the Water Integrated Resources Plan on January 31, 2011. (Watch video of Council meeting.)

Pasadena Water and Power THANKS ALL

this critical resource planning document. We hope that you continue to stay involved as we draft the
2010 Urban Water Management Plan.
