AIM Action Items: Toilets and Urinals
Equipment/Schedule
Frequency Assess Improve/Maintain
Commercial Flushometer Toilets and Urinals Diaphragm Flush Valve
Annually BEM: Assess if flush valves have long flush cycles of greater than 5 seconds; this can indicate a broken, leaking, or improperly rated valve. Submit a workorder if required.
Remove the cap of the valve and assess if the diaphragm gasket is dirty or brittle. Check the flush rating, which should be marked on gasket.
If gasket is dirty: scrub gasket, check flush cycle length to see if flush cycle returns to normal length; if not, replace the gasket
If gasket is brittle, replace with properly rated gasket.
If gasket is improperly rated, replace valve with correctly rated retrofit kit.
Check the flush volume adjustment screw and set to the manufacturer’s specifications.
Residential Tank Toilets Water Level
Annually BEM: Remove the tank lid and check if the water is flowing over the top of the overflow tube and if the tank water level is set at or below the manufacturer’s specifications. Submit a workorder if required.
Adjust the float to lower the tank water level for either of these cases.
Replace the fill valve if the toilet continues to run after the float is adjusted.
Residential Tank Toilets Flapper Valve
Annually BEM: Conduct a flapper valve leak test by dropping dye or food coloring into the tank water, wait 10 minutes, and see if the dye has seeped into the bowl through the flapper valve. Submit a workorder if required.
If there is dye seepage, first ensure that the flapper valve properly drops after a flush. If the flapper is fully dropping into place and seepage continues, the flapper is leaking and needs to be replaced.
Commercial Flushometer Toilets and Urinals Sensors
Annually BEM: Observe if flush sensor is nor working properly (e.g., double flushing) and needs calibration. Submit a workorder if required.
Determine the current schedule of sensor calibration.
Regularly calibrate automatic sensors every 6 months to ensure they are only activated after the user leaves the stall to reduce “double flushing”.
Non-water Urinals Manufacturer’s specification
Obtain maintenance schedule of non-water urinals and determine if it meets the manufacturer’s recommended maintenance.
Clean and replace the sealant, cartridges or material in accordance with manufacturer’s recommendations.
Education and Outreach
Annually Post a sign in the restrooms that will provide a mechanism for occupants to report long flush cycles, visible leaks, and other maintenance issues.
Note that using feet on toilet handles can damage flushing mechanism and should be avoided.
Leadership. Energy. Execution.UNCLASSIFIED/FOUO 26
AIM Action Items: Faucets and Showerheads
Equipment/ Schedule
Frequency Assess Improve/Maintain
Leak Detection Every 6 months BEM: Check for leaks in faucets and showers. Establish a protocol to fix leaks immediately once they are found.
Faucet and Shower Aerators/Flow Restrictors
Every 6 months BEM: Inspect faucets and showerheads for missing or broken aerators/flow restrictors. Aerators and flow restrictors can often be broken or removed causing the fixture to flow at much higher flow rates. Submit a workorder if required.
BEM: Inspect for failing shower diverter valves.Submit a workorder if required.
Replace if needed and install vandal-proof fixtures that are more difficult to break or remove.
Faucet Sensors Every 6 months Determine the current schedule of sensor calibration.
Regularly calibrate automatic sensors to ensure proper operation and reduce long wash cycles.
System Pressure Annually Test system pressure to make sure it is between 20 and 60 psi. Water pressure can be measured with a pressure gauge connected to a water spigot, typically on the outside of a building. Fixtures will consume more than their rated amount of water and cause wear and tear on the fixture at high pressure.
If the pressure is too high, install a pressure reducing valve. A pressure reducing valve is typically placed at the building water meter.
Education and Outreach
Annually BEM: Post a sign in the restrooms that will provide a mechanism for occupants to report visible leaks and other maintenance issues.
Encourage users to take shorter showers; place clocks or timers in or near showers to allow users to track their timing better.

Equipment Maintenance
Every 6 months BEM: For pressure washers, inspect the sprayer, connecting hoses, and the water storage system for leaks and/or broken or missing components. Submit a workorder if required.
BEM: Make sure that open hoses are not being used to wash vehicles. Submit a workorder to replace open hoses with hoses with spray nozzles.
Make sure the main shut-off valve is functioning correctly.
Check flow rates to ensure they are within manufacturer’s recommendations.
For pressure washers perform the following:
Repair or replace broken or leaking components, hoses, and system connections.
Replace the main shut-off valve if it is not operating properly.
If there is no pressure washer, ensure that spray nozzles are attached to hoses.
For facilities that use detergents, use high quality detergents to shorten the duration required to clean each vehicle.
System Pressure Annually Routinely verify that system pressure is within manufacturer’s specifications.
Minimize pump head pressure or install a pressure reducing valve to maintain system pressure based on manufacturer‘s recommendations.
Education and Outreach
Annually Assign a staff member to be responsible for checking equipment and repairing leaks.
Encourage users to wash with brushes rather than water pressure to remove large debris from vehicles.

Leadership. Energy. Execution.UNCLASSIFIED/FOUO 32
AIM Proposed Action Items:
Equipment/ Schedule
Frequency Assess Improve/Maintain
Scheduling At start of irrigation season and at major changes in weather patterns
Review irrigation schedule to determine the time of day and days per week for each zone.
Verify that the irrigation schedule is appropriate for climate, soil conditions, plant materials, and season.
Irrigate during non-windy and low-sun periods to decrease evaporation; early mornings are typically the least windy.
Change the watering schedule based upon changing weather conditions and as part of regular, periodic maintenance; consider installing a rain gauge that is tied into the irrigation controller to automatically shut off the irrigation system during a rain event (called a “rain delay”).
For flat landscaped areas, water deeply and less frequently rather than lightly and often. A deep, less frequent schedule encourages deep roots resulting in more drought tolerant plants.
Irrigate using a “cycle and soak” schedule for steep slopes where surface runoff is likely.
If irrigation is controlled by an advanced weather-based or soil moisture-based controller, ensure that the system is properly programmed for the location and the specific landscape type.
Irrigation Monitoring
Once a month through the irrigation season
Install an irrigation meter to measure the amount of water applied to the landscape. The meter should be an advanced meter with interval data capability and automatic data logging.
Use this data for system analysis to monitor for system leaks and repair needs and to determine a water budget.
Equipment Maintenance
Once a month through the irrigation season
BEM: Periodically walk the landscape grounds and check for standing water, which may indicate a leak. Submit a workorder if required.
BEM: Ask the grounds manager to check emitter components for broken heads and leaks. Common examples of damaged emitters include broken heads, clogged nozzles, nozzle seal leaks, sunken heads, and tilted and misaligned heads.
Require immediate repair of broken components; adjust as needed so that they efficiently water the landscape and not the hardscape.
Landscape and Irrigation
Leadership. Energy. Execution.UNCLASSIFIED/FOUO 33
AIM Proposed Action Items:
Landscape and IrrigationEquipment/ Schedule
Frequency Assess Improve/Maintain
Landscape Maintenance
Annually Review the current landscape maintenance practices (aeration, mowing, mulching, amendments, and weeding) and timing.
Aerate turf at the beginning of the irrigation season to introduce oxygen into the soil and encourage deep root growth.
Alternate turf mowing height between high and low levels and alternate mowing patterns that encourage deep root growth and drought tolerant turf.
Add mulch to landscaped areas to help reduce evaporation, inhibit weed growth, cool plants’ root zone, and reduce erosion.
Amend the landscape soil with organic matter 4 to 6 inches deep, which will help to capture stormwater and retain moisture.
Keep landscaped areas weed free; weeds can take up valuable water and nutrients that are needed by the landscape.
For new construction and renovations, design landscapes to be native and/or adaptive plantings that have low watering requirement. (Follow the new construction checklist requirements.)
System Pressure Annually Verify that irrigation system pressure is within manufacturer specifications once per irrigation season.
Install a pressure reducing valve if pressure is found to be over the manufacturer’s specification.
Performance Measurement
Annually Review grounds maintenance contracts to determine if water efficiency certification and water use/performance is part of contract requirements.
Require the grounds maintenance staff/contractor to become an U.S. Environmental Protection Agency's (EPA) WaterSense Certified Irrigation Professional.
Incorporate a water budget, which can be used as a performance standard for water consumption. Calculate water needs based on the landscape’s requirement and use that information to plan an irrigation schedule to meet those needs.
Irrigation Audit Every 3 years Contract with a qualified irrigation auditor to perform a system irrigation audit that follows procedures outlined in the Irrigation Association’s Certified Landscape Irrigation Audit Program or equivalent. The result of the audit determines the system’s distribution uniformity.
Based on the results of the audit, make adjustments to the irrigation system to increase the distribution uniformity2.
Education and
Outreach
Annually BEM: Provide a clear mechanism for building occupants to report an irrigation leak, broken and misaligned sprinkler heads, and watering during a rain event.
Encourage grounds maintenance staff to sweep driveways and impervious surfaces rather than spraying them clean.
