A recent government survey showed at least 36 states are anticipating local, regional, or statewide water shortages by 2013. By using water more efficiently, we can help preserve water supplies for future generations, save money, and protect the environment. (Environmental Protection Agency (EPA), 2009)
Obvious places to consider water efficiency in the workplace include kitchens and rest rooms. Select water efficient devices to replace older fittings when feasible. Examples include:
- low flush toilets
- low flow shower heads
- auto sensor or push down auto shutoff taps
- faucet aerators
For landscaping and irrigation projects choose low impact designs integrating native plants that require minimal watering. Consider drip irrigation systems.
Water efficiency can include reducing the amount of storm water runoff that can have a major impact on Portland’s Combined Sewage Overflow system. Consider integrating water control features such as ecoroofs, bioswales and rain water harvesters into building grounds and landscaping projects.
Things to look for:
- Low flow
- Auto-sensors
- Flow restrictors or aerators
- “High efficiency” labels or certifications
Things to avoid:
- No flow regulation
- Non-native plants that require more water than native species.
