Creating an accurate irrigation schedule can be difficult, but Valley Water has created a powerful irrigation scheduling tool to help take the guesswork out of how much your landscape should be irrigated.  This free tool, available to landscapes throughout California, will assist you in creating accurate, water-conserving irrigation schedules for either your conventional or smart controller.

The Valley Water Irrigation Scheduler uses historical weather data based on your site location, along with landscape-specific inputs, such as plant type, irrigation equipment, and sun exposure, to calculate a custom irrigation schedule for your California landscape.  The Irrigation Scheduler can also accommodate drought watering restrictions, such as days per week watering limitations.

What is a water-wise plant?

"A term used to describe water- and plant-management practice that emphasizes using plants that have lower supplemental water needs and grouping plants by water needs to encourage more efficient water use." - gardening magazine

Valley Water is seeking experienced Landscape Designers and Architects for our Landscape Design Assistance Program. The Landscape Design Assistance program aims to engage professional landscape designers and architects with customers to help achieve low water, California-friendly, and climate-appropriate landscapes.  

To support customers with their lawn conversion rebate projects, Valley Water will reimburse customers $200 for a 1-2 hour design consultation with a professional Designer. While the consultation will not provide enough time for the designer to draw a detailed landscape plan, Designers are expected to discuss site conditions, and customer needs, and to develop general ideas for landscape layout and plant choices.

Lawns can be the single biggest water user for a typical property; a small lawn can use more than 18,000 gallons a year. That means lawns offer the greatest potential for water savings! Consider eliminating unused lawn and re-landscaping with permeable paving materials and plants appropriate for our local climate.

Maintaining and watering lawn during drought

During a drought or high temperatures, managing the water that you apply to your lawn is essential. Following some simple maintenance best practices can also help it survive the drought.

Tips include: 

• Water less. Reduce the number of watering days per week and/or reduce the minutes of watering per day. The lawn won’t look its best, but it will survive.
   
• "Cycle and soak” method.  Split your watering time into two cycles spaced about an hour apart to allow the water to soak in, reducing runoff and water waste.
   
• Check your sprinkler heads. Repair broke, crooked or sunken heads and clogged nozzles. Adjust the spray pattern to prevent sprinklers from watering pavement.
   
• Adjust mow height. Mow lawns 2½-to-3 inches high once a week. Taller grass blades promote deeper roots and will shade the soil, resulting in less evaporation.

General lawn care tips

• Lawn irrigation, fertilizer-use, and maintenance information from the California Water Efficient Partnership.
   
• Thinking of artificial turf? Although artificial turf is appropriate for some properties and uses less water than natural turf, the district’s artificial turf information sheet may help encourage you to choose low water-using landscapes that can effectively promote biodiversity and help fight climate change instead.

How do I prevent evaporative water loss from my pool?

Evaporation from swimming pools contributes to water and energy waste. Evaporative water loss from uncovered pools can waste 12,000 to 31,000 gallons of water a year (EPA WaterSense). Using a pool cover can prevent up to 95 percent of pool water evaporation. Pool covers also keep debris from contaminating pool water and clogging filtration systems.  

How do I check for leaks in my pool?

Leaks in your pool’s structure or plumbing system can also be the source of significant water waste. Regularly check your pool for leaks to reduce the amount of water needed to refill on a regular basis. To determine if your pool has a leak,

1. place a bucket on the top step of the pool,
2. fill it with water to the water level of the pool.
3. leave the bucket for 24 hours, and if after that time the water loss in the pool is greater than the water loss in the bucket, you likely have a leak.

Also, to prevent water loss, be sure not to overfill your pool and to regularly check the auto-fill valves to assure they are not stuck.

Learn about more water efficiency tips for your pool in the EPA WaterSense Pool Water Efficiency Guide.

Does Valley Water have restrictions on pools?

Restrictions on pools, including refiling, new construction, and pool covers are set by individual water retailers and/or cities and may vary throughout the county. As a water wholesaler, Valley Water does not have land use authority and cannot prohibit the construction of pools. The construction of a pool is permitted and approved by the local jurisdiction’s building and/or planning department(s). Additionally, the local water retailer has the authority to restrict the filling or refilling of swimming pools. Valley Water encourages replacing existing pools with low water use landscape by offering a rebate of $2/square foot through the Landscape Rebate Program.

To address the current drought conditions, Valley Water’s June 9, 2021 resolution (Resolution No. 21-68) declaring a water shortage emergency urges the County, cities, and water retailers to prohibit the use of potable water for the filling or refilling of swimming pools, among other water use prohibitions. Similarly, the regulatory agency overseeing private water retailers encourages comparable water use prohibitions; however, the decision to implement and enforce water use restrictions affecting pools lies with the local water retailer. 

How can I find out if there are pool restrictions in my City?

We recommend residents and businesses contact their individual water retailers for information about restrictions and/or guidelines on pool construction, filling, and maintenance. To find your retailer, visit www.valleywater.org/your-water/find-your-water-retailer.  While some municipalities have requirements already in place for new pools to install pool covers. If the drought worsens, most municipalities will move to restrict pool installation and fillings through their Water Shortage Contingency Plans.
