Water Conservation

Of all the Earth’s water, 99% is salt water, frozen, or too polluted for human consumption. Only 1% of the Earth’s water is available for drinking.

We think of the Pacific Northwest as a place of abundant rainfall and plentiful water. But, think about this: our population is rapidly growing, urban areas are sprawling, our climate is changing, our summers are becoming warmer and drier, and our water demands continue to grow even though our water supply is limited. During the summer months, our region relies primarily on water stored from precipitation in storage reservoirs, rivers, or groundwater. Since the average household consumes 100-400 gallons of water per day, reducing the demand on our existing water supply will help stretch available water resources.

Weekly Watering Number

Over-watering is one of the most common problems in home and commercial landscapes. To help, the Regional Water Providers Consortium provides a weather forecast and Weekly Watering Number. The Weekly Watering Number is a tool that helps you determine the amount of water that your lawn will need each week in April - September, and can be adjusted for different types of plants. The number changes with local weather conditions and is specific to your area. If you aren’t sure how much water you’re using, try using a tuna can as a 1” measuring gauge, or contact the City Water Conservation Program for a free rain gauge.
