Basic Palmdale Watering Information

What Time of Day Should I Water?

In Palmdale, we recommend watering between 2 a.m. and 6 a.m. Watering within this window of time takes advantage of relatively low winds and less loss of water to evaporation.

How Long Should I Water?

Generally, because of our clay soils, running an irrigation system on a lawn for more than five minutes will result in runoff. Precise watering times vary depending on the type of watering device, soil, slope and plants.

How Often Should I Water?

In Palmdale, water in the early morning hours between 2 a.m. and 6 a.m. You can follow the quick method below, but remember PWD provides each customer with a water budget allocation each month. To determine a more accurate irrigation schedule please see Determining your Irrigation Schedule.

Determining your Irrigation Schedule

The Palmdale Water District provides its customers with a water budget allocation each month using ET (evapotranspiration) for outside irrigation. In the winter months the water budget allocation is low and gradually increases as the weather changes and becomes warmer. As the weather becomes cooler again the water budget allocation becomes low again. The outside water budget allocation is determined by the total square footage of the customer’s parcel and the amount of water required to maintain a healthy landscape. The irrigable area is estimated to be 45 percent of the total parcel area and is calculated in units of water (one unit is 748 gallons of water). The graph below shows a historical water budget allocation for a 7000 square foot lot. Fixing leaks inside and outside the home especially irrigation leaks and a watering schedule is extremely important in order to stay within the customer’s water budget allocation each month.

The District also provides an indoor water budget allocation based on a default of 4 people in the home, which is 10 units of water per month. Customers can add the indoor allocation (10 units) and the monthly outdoor allocation together and get a good estimate of their total monthly water budget, also found on their monthly water bill. Customers can use the graph below to adjust their irrigation controllers (timers) to water based on historical ET.

One unit of water equals 748 Gallons of water.
