- Conduct a water use audit to identify conservation opportunities.
- Install water efficient equipment, appliances, and plumbing fixtures.
- Visit WaterSense for information on low-flow plumbing fixtures, aerators, on-demand faucets, dual flush toilets, waterless urinals and other water efficient plumbing fixtures.
- Optimize water use for heating and cooling systems.
- Eliminate single pass or once-through cooling systems.
- Minimize water loss from cooling towers.
- Ensure that boilers and steam-generating systems operate efficiently.
- Eliminate non-critical cleaning processes and maximize dry cleanup where feasible.
- Optimize production sequencing and scheduling to reduce cleaning.
- Where feasible, use dry cleanup processes (sweeping, squeegees, etc.) rather than hosing down floors and other surfaces. Use high-pressure, low-volume water nozzles when you do need to use water for cleanup.
- Wash fleet vehicles only when necessary and use a car wash facility that recycles water.
- Use harvested rain water for non-potable use (e.g. flushing toilets) or landscape irrigation.
- Landscape with native and drought-resistant plants and minimize turf.
7. Optimize irrigation systems.
- Limit irrigation areas.
- Identify and repair leaks.
- Adjust irrigation schedules to account for seasonal rain variation or use rain gauges.
Stormwater Management & Site Design
(Note that for some facilities, stormwater and spill prevention plans and measures are a regulatory requirement.)
- Reduce stormwater runoff through landscape design, reduction of impervious surfaces, and green infrastructure.
- Plant vegetative buffer strips along streams and other bodies of water.
- Keep pollutants out of storm drains and waterways.
- Store equipment and materials indoors or undercover.
- Routinely check paved surfaces for possible oil leaks from company vehicles.
- Educate employees to ensure “Only rain down the drain!”
- Plug floor drains in maintenance shops so that spills don’t discharge to stormwater drains or check with your local government about redirecting drains to the sanitary sewer system.
- Keep spill containment kits on site and accessible. Include them in your fleet vehicles if appropriate.
- Implement Integrated Pest Management (IPM) practices.
- Apply fertilizer only when necessary and at minimum rates.
- Use native plants to minimize use of fertilizer.
- Limit fertilization of grass to once a year (summer for Bermuda and zoysia grasses, fall for all other grass types.)
- Keep fertilizer off of paved surfaces to prevent it from entering a storm drain.

- Bay-Wise Landscape Management
Alternatives to Salt
- Use best management practices to control ice on paved surfaces.
