Facilities that use water efficiently can reduce costs through lower water use fees, lower sewage volumes to treat, and lower capacity charges and limits. Using large volumes of water increases maintenance and lifecycle costs for building operations and increases consumer costs for additional municipal supply and treatment facilities. Many water conservation strategies involve either no additional cost or rapid paybacks.
REDUCE WATER CONSUMPTION:
• Replace existing plumbing fixtures with low-flow fixtures
• Replace existing toilets with low-flow dual-flush toilets
• Re-design landscaping to reduce need for irrigation
| Rainwater Re-Use System |
 |
Rainwater systems provide non-potable water suitable for landscape irrigation, flushing toilets and urinals, and process water needs. Rainwater systems have significantly fewer code requirements and are often less expensive than graywater systems. Rainwater from roofs or site can also be collected and harvested to help displace potable water demand. Rainwater collected from impervious surfaces reduces rainwater runoff and controls infrastructure requirements. Rainwater retention or detention systems can be designed with cisterns to hold rainwater runoff for non-potable usage.

| Graywater Re-Use System |
|
Potable water is used for many functions that do not require high-quality water such as toilet and urinal flushing and landscape irrigation. Rainwater and graywater systems can significantly reduce potable water demand. Graywater systems reuse the wastewater collected from sinks, showers, and others sources for the flushing of toilets, landscape irrigation, and other functions that do not require potable water.
