map_marker_plain_icon.pngWeather station data is electronically transmitted daily to IRWD and used to calculate evapo-transpiration, also known as ET, which is the amount of water needed by turfgrass to remain healthy in each specific climate zone. IRWD's billing system relies on accurate weather station data to provide landscape and commercial customers like you with site-specific allocations to ensure that your landscaping receives sufficient water.

If your HOA maintains large common landscaped areas, the many links and tips on the page could be helpful in saving you water and money.

Important note: Water budgets for potable water accounts are based on 60% warm season turf and 40% drought tolerant landscape irrigated with a water-efficient system, such as drip. If you maintain your current watering schedule for grass, you will most likely go over your allocation and result in a high water bill. View the latest Prop 218 notices
