State Mandates New Water Conservation Framework Using Reliability Stress Test
In May 2016, the State Water Resources Control Board (State Water Board) voted to sunset the water conservation standard formula, which required water districts to reduce water use by a certain state-mandated percentage. To replace the mandated percentage reductions, the State Water Board introduced a new requirement for local suppliers, like the City of Pasadena, to apply a prescribed Reliability Stress Test and set water saving targets based on anticipated water shortfalls over the next three years.
Although California is still in an emergency drought situation, State officials recognize that supply conditions have improved and as a result, drought rules were revised effective June 1 2016, ending Pasadena’s 26% conservation target as well as California's 25% overall target. As a result, Pasadena’s Water Savings Gauge has been retired as well.
PWP completed the Reliability Stress Test and submitted the required documents to the State Water Resources Control Board in June 2016. Results of the Reliability Stress Test are used by each agency to create a new local water conservation standard. Under the new regulations, California’s wholesale water agencies are also required to calculate water supplies that they anticipate will be delivered to member agencies. PWP relied on calculations performed by the Metropolitan Water District of Southern California to determine the available supply of imported water for the Reliability Stress Test calculations.
PWP has submitted the following documents to the State Water Board:

Level 2 Shortage Plan
As a reminder, Pasadena is still on a Level 2 Shortage Plan under City Ordinance Chapter 13.10, which became effective on June 1, 2015.
The plan limits outdoor watering to two days per week on Tuesdays and Saturdays from April 1 through Oct 31, and one day per week on Saturdays from Nov. 1 through Mar. 31.
The plan also prohibits watering between the hours of 9 a.m. and 6 p.m., requires water leaks to be fixed within 48 hours, and prohibits the filling of ornamental lakes and ponds. (Please note that the fall/winter watering schedule was also one day per week in 2014 under the previous Level 1 Water Shortage Supply Plan.)

Water Waste Enforcement will still be in effect to ensure Pasadena meets the goal of Senate Bill X7-7, which calls for 20% reduction by 2020.
We want to thank the Pasadena community for making great strides with conservation.
Key Things to Consider - A Sustainable Water Future
If the limited outdoor watering days are creating brown patches on your lawn, consider placing drought-tolerant plants in hard-to-water areas.
- If you plant drought-tolerant landscape, altering your irrigation is key to seeing long term water savings.
- Check out our online landscape designs for ideas
- Consider hardscape options: patios with pavers, hammocks with overhead covering, etc.
- Think about other ways to reduce your outdoor water use:
Yes, outdoor watering makes up 60% of an average household, but there are also ways you can change your indoor water habits to create 20-25% reduction in your overall water use.
REBATES & INCENTIVES
From Pasadena Water & Power and SoCal Water$mart*:
Please note: PWP does not endorse any specific vendor. PWP encourages residents to obtain multiple quotes, check references, and check product reviews. Pasadena residents may select any vendor when participating in any PWP rebate program, including turf removal.
KEY CAPITAL water projectS
PWP is investing in several capital projects that would help to not only replenish our local water levels, but create sustainable alternative water sources
- Arroyo Seco Canyon would stabilize our water levels by bringing in local water to replenish our groundwater
- Recycled Water would help offset the use of drinking water for irrigation and cooling processes at nearby hospitals and commercial/industrial buildings
