Summer Drinking Water Supply

When summer returns, do your part to use water wisely. It's just the right thing to do.

Below is some information to help you learn more about your drinking water and what you can do to conserve:

  • Water supply, water sources, and water treatment methods are different throughout the region and the state. Find out who your water provider is or if you are affected by a drinking water advisory by using the look-up tool and learn more about your water source here
  • Your local water provider and other state, and federal agencies track water supplies closely throughout the year, especially during the summer months. The Oregon Water Resource Department provides a weekly water conditions report which you can sign up to receive via email.
  • The Consortium’s 20+ water providers have been proactively planning for more than 20 years to ensure that the region’s water needs can be met in the face of drought or other water shortages. Portland metro area water providers are continuing to work closely together throughout the year to track the region’s changing water supplies, and are ready to proactively address any issues that may arise. 
  • Water providers and their customers take conservation seriously. Despite population growth, per capita water use has steadily declined in the region in large part due to water conservation. 


We don’t have water to waste. Here are five ways you can do your part to use water wisely all year:

  1. Sign up for the Weekly Watering Number. Your plant’s water needs will change throughout the summer, and so should the amount you water. The Weekly Watering Number is the amount of water in inches that you will need to water your lawn and other plants each week. It is based on weather in your zip code, and we will send it to you for free by text or email. Sign up and start watering smart today!
  2. Make sure that your watering system is in tip top shape for summer. This includes tightening hose connections and checking that your sprinklers are working correctly and positioned to water plants and not the pavement. 

  3. Water less frequently, but for longer.  Established landscapes and lawns need to be watered two times per week. Newer plantings, vegetables, and potted plants may need more frequent watering. Watering less often will encourage your plants to develop a deeper root system so that they are better equipped to handle warmer, drier weather. 
  4. Prevent run off by applying only the amount of water your soil can absorb. Much of the soil in the Portland metro area is clay which means it holds onto moisture well but takes longer to absorb. You may need to break-up your watering session to give your soil time to soak up the water you are applying (e.g. water for 10 minutes, wait 30 minutes for the water to soak in, water again for 10 minutes). 
  5. Make the switch and save. WaterSense fixtures and appliances like smart irrigation controllers, faucet aerators, showerheads, and toilets use at least 20% less water than standard models. Check to see if your water provider has a rebate program for appliances like automatic sprinkler systems and toilets, and if they give their customers conservation devices like showerheads or faucet aerators.
