Enterprise Community Partners | 6GREEN & HEALTHY LIVING: Water Conservation Why And How To Track Water Usage Why? Helps owners understand how much is used by a building to target retrofits and conservation. Helps owners compare building is normalize data per person or per bedroom. Triggers water conservation actions to save owners money and save water. How? Collect and input water data. Explore benchmarking/tracking software. Review data monthly or quarterly, when new data are entered.

Enterprise Community Partners | 10GREEN & HEALTHY LIVING: Water Conservation Myths Or Realities Of Water Usage Shower use accounts for the greatest amount of water used by most people (excluding irrigation). Toilets installed before 1993 use nearly twice as much water as toilets available in Low flow toilets just don’t work. Water conservation can yield significant savings.

Enterprise Community Partners | 11GREEN & HEALTHY LIVING: Water Conservation Daily Water Use Targets Super Water Conserver: <44 gallons/person <66 gallons/bedroom* Sources: American Water Works Association (2010) & Steven Winter Associates Poor Water Conserver: >55 gallons/person >83 gallons/bedroom* Good Water Conserver: <55 gallons/person <83 gallons/bedroom* *Targets assume 1.5 people per bedroom

Enterprise Community Partners | 12GREEN & HEALTHY LIVING: Water Conservation Water Saving Opportunities for Owners 1.Leaks: Fix problems that are wasting significant water. Check usage data for spikes. Check meters at 3 am, when usage is low to identify leaks. 2.Low Cost Upgrades: Effective actions in most properties: repair toilet flappers; install low flow showerheads and aerators. 3.Rehab Opportunities: Replace toilets (especially 3gpf) with EPA WaterSense, upgrade clothes washers with WaterSense equipment, complete upgrades in #2 above.

Fix Leaks Leaking toilet could waste 100 gallons/day Faucet leak 1 drip/second wastes 5 gallons/day Hot water leaks waste water and energy Leaks account for 14% of household water use Severity of leaks can be found by looking at your water meter at 2am –Water running at that time is typically from leaks
