Creekside Recycle Water Improvement Project

Given constrained supplies in Southern California, water is a precious commodity that is critical to the City’s ability to achieve its Vision.

There are four sources of water in Ontario:  groundwater, imported water, recycled water and local precipitation.  Ontario’s potable water supply comes predominantly from a combination of groundwater and imported sources.  Recycled water is available for non-potable purposes in portions of the City. 

Some urban run-off is captured and used for recharging the aquifer, but most travels through the City during storm events via natural and man-made systems to Prado Dam.  Protection of ground and surface water quality is important to the continued availability of the resource.  Wholesale recycled water is available through the Inland Empire Utilities Agency (IEUA) for distribution by the City.

The City maintains a wastewater collection system and contracts with the IEUA for wastewater treatment.  IEUA also operates an industrial non-reclaimable wastewater system, which runs through Ontario and is available to our industries.

Ontario recognizes that all water sources are not of equal quality, but all water has value and the water used should match the water quality required for the use.  Recycled water, for example, should be used for landscape irrigation. The City’s approach to water resources is to conserve when possible, reclaim and reuse where feasible, and ensure “the right water for the right use.”

Proposed Uses in Creekside West

  • Common area landscaping
  • Greenbelts

The Color Purple – Know the Signs

Soon, you will began see purple signs popping us throughout Creekside West. These signs will be mostly seen in the common area landscape within the community.

When you see the color purple used in sprinkler systems, it means that the water is being reused and is not fit to drink (non-potable).

The color purple can show up on:

  • The valve boxes which are normally green;
  • The irrigation pipe which are normally white;
  • The nozzles that are placed in the head of a sprinkler or rotor which are normally black.  The sprinkler head may have a purple wrap.
  • The valve covers which are normally black;
  • The quick coupler valve which are normally metallic.

A lot of local, state, and federal governments and schools are implementing recycling the water to help save water, money, and the environment.  Every gallon of recycled water used for these purposes saves a gallon of drinking water.

The use of purple piping has become the international symbol for recycled water.

What about the drinking water?

The recycled water is delivered completely separate from the drinking water infrastructure.  This is to prevent recycled water from getting into the public distribution systems.

Some people ask what the difference is between recycled water and grey water.  Recycled water is wastewater that has been treated for reuse for approved non-potable uses which are primarily landscape irrigation.  Grey water includes untreated wastewater from bathtubs, showers, washing machines, etc.  Grey water normally is only used to irrigate landscapes at the site at which the grey water was generated and the irrigation is an underground system.

Not safe for play!

Even if it is really hot out and your children beg you to run through the sprinklers, take the time to educate them on recycled water and if they were to get the water on them, they would need to wash off with clear water right away.

If you have more questions regarding reclaimed water in your area, please direct questions and comments to the City of Ontario Planning Department.  Please include the relevant component, element and/or section that you have comments or questions on in your email or voicemail.
