Water Quality

In 1996, passed under the "Safe Drinking Water Act," was the Consumer Confidence Report (CCR) The intention of the CCR is to keep the public aware of the quality of their water. It is a mandatory report that must be written and made available to the consumers each year. It is your guide to making sure your water is safe. CCR's for the past year are due and will be posted by July 1st of the following year.

Cross Connections & Backflow Testing

The State of Idaho code for Cross Connection requires that all homeowners and businesses have testable backflow devices on sprinkler systems and that all outside hose bibs are anti-siphon. In 2003, EEWA Board of Directors was authorized by the members to manage the annual backflow testing for backflow prevention assemblies connected to the water system.  View details about Backflow Testing

Emergency Water Backup

In September 2016 Emerald Estates Water Association established an emergency backup water connection with Avondale water. The emergency vault between our two systems acts as a safety net for Emerald Estates and allows water to flow only one direction, from Avondale to Emerald Estates.


The pressure monitoring valve in the vault can be set to be activated at any pressure, currently it is set at 45 psi. The valve allows no water to pass through the vault when Emerald pressure is above 45 psi, at any pressure drop below 45 it opens and maintains 45 psi. Although 45 psi is not ideal, it is better than depressurizing and also provides fire flow in an emergency. When Emerald restores its own pressure and gets to a point above 45 psi the valve closes and does not allow flow.


A perfect scenario is when the power goes out. The pumps will not run; therefore, the pressure drops. At the point it hits 45 psi, the valve in the vault allows water to pass through until a point that power is restored at which point the pumps turn back on and restore the pressure. At this point the valve closes. In some instances when the power is restored the Emerald pumps need reset before they will start, which is the reason that pressure remains low after the power comes back on. In the instance there is a planned outage and Emerald Estates knows they are going to be using Avondale's water for a few days, they can request that we turn up the pressure from 45 to full system pressure, which is about 65 psi.

Watering Tips

Help preserve our precious resource and conserve water wherever possible.

Water Efficient Lawn Watering Practices

Summer lawn watering creates large demands on local water utilities. Water supply treatment and storage facilities are often built two, three and even four time larger to supply additional demands created by lawn watering. This extra capacity is not used for most of the year and adds significant costs to the design, construction and operation of a water system. Water customers and communities can save money by using water more efficiently. These water efficient lawn watering practices can help maintain a beautiful yard and conserve valuable water supplies.


General Information

 Adjust sprinklers to water only grass areas and not impervious surfaces such as streets, driveways and walkways. Mow grass to a height of  2 to 3 inches. Taller grass shades the roots and soil surface, which helps reduce the amount of water that is lost to evaporation.  Use sprinklers that spray low large drops vs. high fine ones.  Use hand held soakers for small trees, shrubs and plants.  Use shut off nozzles on hoses and repair leaky hoses and fittings.


When To Water

About one inch of water per week (including precipitation) is adequate for maintaining a healthy lawn. Use a can or rain gauge to help determine the amount of water applied by the sprinkling system and supplied by rainfall.  Don't use a fixed schedule for lawn watering. Apply water only when it is needed. Over watering can promote diseases and affect the health of the lawn.  A simple test for determining if grass needs water is to walk on the lawn and if you leave foot prints, it may be time to water the lawn.  Using a spade or gardening tool to check soil conditions 2 to 6 inches below the surface can provide information on soil moisture and the need to water.  A good soaking once or twice a week is better than watering every day. Allowing the soil to dry between watering will allow the roots to grow to greater depths and help make turf more drought tolerant.


Best Times For Lawn Watering

 Water during the cool part of the day to minimize water lost to evaporation. Early morning hours (4 a.m. to 8 a.m.) are the best, and the peak water consumption hours (4 p.m. to 9 p.m.) should be avoided.  Avoid watering during midday hours when it is hot and sunny to prevent scalding the turf.  Watering at night is not recommended because the lawn stays wet for a long period of time which can promote diseases and affect the health of your lawn.  Avoid watering during rainy or windy weather conditions.


Automatic Lawn Watering Systems

An automatic timer is part of most buried sprinkler systems, but can be added to any sprinkler system for a very low cost. Automatic timers make it easy to set sprinkling systems to apply specified amounts of water during the best times of the day.  Set systems to turn on between 4:00 a.m. and 8:00 a.m. in the morning.  Set the system to turn on for three 10 minute sessions with each session 2 hour apart to improve water infiltration and reduce runoff.  Equip the system with moisture sensors so the system does not turn on when it is raining.  Set the automatic timer to water every 3 or 4 days adjusting the time and frequency, as needed, to accommodate changes in seasonal water demand.


Watering Restrictions

Local watering restrictions are sometimes necessary due to limited treatment capacity or reduced water supplies caused by mechanical problems or drought conditions. Water efficient lawn watering practices can help reduce the need for watering restrictions and expensive expansions to the water system. Here are a few recommendations in the event lawn watering restrictions are needed.  Water less frequently and gradually reduce the amount of water. This will help reduce stress and condition the turf if a total ban on lawn watering becomes necessary.  Reduce the amount of foot traffic allowed on the lawn as much as possible.  Allow the grass to grow longer to reduce moisture loss from the soil.


New Lawns and Landscaping Alternatives

Adding organic matter before seeding will help improve water and nutrient retention.  Reduce water requirements by using drought-tolerant grass seed and sod.  Reduce turf areas by planting drought-tolerant trees, shrubs and plants.
