1. What is Recycled Water?

Recycled water starts out as wastewater. After arriving at the wastewater treatment plants, the water is then purified so it is suitable for landscape irrigation and other non-drinking purposes. Wastewater is processed through biological treatment, filtration, and a disinfection system before it becomes recycled water for landscape irrigation. A dedicated system of pipelines is constructed for recycled water, which is completely separate from drinking water pipelines. These pipes are colored purple to distinguish them from drinking water pipes.

2. Is Recycled Water safe?

Yes; recycled water goes through a series of purification steps that clean the water to make it safe for virtually all non-potable uses, including landscape irrigation, agricultural farming and industrial applications. Recycled water originates from wastewater; therefore its use is strictly regulated and monitored by the State Water Resources Control Board Division of Drinking Water (DDW). These guidelines are precautionary measures intended to protect the public from any potential risk associated with recycled water. The water delivered through the City’s system will meet DDW standards suitable for body contact recreation.

3. Why is the City of Chino Hills planning for Recycled Water?

Water supplies in California are being stretched to the limit of our available supply because of population increases, environmental restrictions and periodic droughts. To ensure an adequate supply of potable water for a growing community, recycled water adds a new source of irrigation water that is locally produced, is drought-proof, and offsets potable water use.

5. What are the benefits of using recycled water?

Using recycled water conserves drinking water supplies. Recycled water, produced at Inland Empire Utilities Agency (IEAU) from sewage water collected from the surrounding communities, conserves drinking water. Recycled water has nutrients that can reduce the use of chemical fertilizers and will cost less to use than drinking water. It is drought-proof, which helps protect local investments in parks, golf courses and other landscaped areas. Additionally, it benefits the environment – it is reusing a scarce resource for today and future generations. See Inland Empire Utilities Agency for More...
