  1. Prepared for Enterprise Community Partners

  2. What Uses The Most Water? • Understand the value of tracking water usage • Identify 4 significant water usages in buildings • Identify 3 actions property managers can take to conserve water • Understand how to evaluate the cost effectiveness of water conservation strategies Faucets, 11 Gallons Shower, 12 Gallons Leaks, 10 Gallons Clothes Washer, 15 Gallons Toilet, 19 Gallons

  3. Water Is A Precious Resource • The World’s Water by the Numbers 97% = oceans 2% = glaciers 1% = suitable for drinking • 85% of the US population relies on public water supplies Source: NRDC

  4. What Uses the Most Water? 69 Gallons/Person/Day Other, 2 Gallons Other, 2 Gallons Faucets, 11 Gallons Faucets, 11 Gallons Shower, 12 Gallons Clothes Washer, 15 Gallons Leaks, 10 Gallons Baths, 1 Gallons Dishwasher, 1 Gallons Toilet, 19 Gallons Source: American Water Works Association, Drinktap.org 2010 & Handbook of Water Use and Conservation

  5. Water Use Doesn’t Measure Work Order Costs Water repairs are the most common work orders in this Boston MA multi family property. Electrical 9% Appliances 6% Water Related 29% Pest Control 2% CO/Smoke Alarm 6% Painting 7% Other 26% Flooring 15% Source: Urban Edge Boston MA & The National Center for Healthy Housing

  6. 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.

  7. Tracking Water Use Water Consumption Gallons/Bedroom Gallons/Bedroom/Day Source: WegoWise

  8. Tracking Water Expenses Annual Boston Area Water Expenses per ApartmentSometimes usage in gallons is not available, dollars provide clues about extreme use 5 to 1 ratio in expenses from about $1500/apartment to low of $300/apartment

  9. Key Steps to Benchmarking • Gather water bills. • Confirm meters for each building. • Enter data in tracking software or spreadsheet. • Examples of benchmarking software for water and energy: • www.wegowise.com • www.psdconsulting.comBuilding Performance Compass • www.brightpower.biz

  10. 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 2010. • Low flow toilets just don’t work. • Water conservation can yield significant savings.

  11. Daily Water Use Targets Super Water Conserver: <44 gallons/person <66 gallons/bedroom* Good Water Conserver: <55 gallons/person <83 gallons/bedroom* • Poor Water Conserver: • >55 gallons/person • >83 gallons/bedroom* Sources: American Water Works Association (2010) & Steven Winter Associates *Targets assume 1.5 people per bedroom

  12. Water Saving Opportunities for Owners 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. Low Cost Upgrades: Effective actions in most properties: repair toilet flappers; install low flow showerheads and aerators. Rehab Opportunities:Replace toilets (especially 3gpf) with EPA WaterSense, upgrade clothes washers with WaterSense equipment, complete upgrades in #2 above.

  13. 1. 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

  14. 2. Repair or Replace Toilets • New Toilets – Use EPA Water Sense 1.28 gallons/flush (gpf) • Existing Toilets – Fix leaking flapper or replace pre-1993 toilets using > 3 gpf Flapper

  15. Evaluate New Toilet Performance • Consult MAP (Maximum Performance) testing annual study for detailed results: • Water use • Performance in flushing solid matter • Download MAPT results from www.map-testing.com Simulated solid matter for toilet testing

  16. 3. Replace Faucet Aerators • EPA Water Sense Aerators 1.5 gallons/minute (gpm) • Or better in bathroom, try .5 gpm • Water pressure can affect performance, test aerator

  17. 4. Replace Showerheads • EPA Water Sense 2 gpm • Or better: <1.75 gpm

  18. 5. Use ENERGY STAR Clothes Washer • Use ENERGY STAR Washer • Use 30% less energy and over 50% less water than regular washers

  19. EPA WaterSense Program • Labeled products 20 % more water efficient • Products tested & listed on website www.epa.gov/watersense • Products include: • Toilets • Showerheads • Faucet aerators • Urinals

  25. Water Case Study: Retrofit Payback Source: WegoWise

  26. Water Case Study #2: Retrofit Payback • Retrofits in 14 buildings, including: • Fix leaks • Replace toilet flappers • Install low flow showerheads (1.75 gpm) • Install low flow aerators • Payback is under 6 months. Source: WinnResidential

  27. What Would You Do? • Complete Exercise Water Conservation 1 • Review baseline conditions: • Water usage 92 gallons/person/day • Toilet: 5 gpf (leaking) • Showerhead: 4 gpm • Kitchen Sink: 2.5 gpm • Bath Sink: 2.5 gpm • What is the water use & payback for the below actions: (use spreadsheet package #1) • Showerhead: 2 gpm • Kitchen Faucet: 1.5 gpm • Bath Faucet: 1 gpm • Toilet: 3 gpf (assumes flapper repair to 3 gpf existing toilet achieves 3 gpf)

  28. How Does Toilet Replacement Affect Payback? • What is the water use & payback for the below actions: (use spreadsheet package #2): • Showerhead: 2 gpm • Kitchen Faucet: 1.5 gpm • Bath Faucet: 1 gpm • Toilet: 1.28 gpf (WaterSense approved) • How does replacing the toilet versus repairing the existing toilet affect payback? • Note we assume $450 for toilet replacement costs (parts and labor – you can adjust these assumptions) Try a package of your own design.

  29. Property Management Actions • Review baseline data & target high users > 83 gallons/bedroom/day • Repair leaks • Fix running toilets • Install low flow faucets • Install low flow toilets • Install low flow clothes washers • Reduce irrigation • Finance internally or use 3rd party

  30. Together, We Can Make A Difference! Bathroom 11 Gallons Don’t Run Bath Faucet Install Bath Aerator 1 Gallon saved/day Kitchen Sink 24 Gallons Don’t Run Kitchen Faucet Install Sink Aerator Showers 20 Gallons Shorter Showers Install WaterSense Showerhead Toilets 20 Gallons Report Leaks Repair Leaks Resident: 51 Gallons Saved/DAY Management: 40 Gallons Saved/DAY Together: 90+ Gallons Saved/DAY + =

  31. The Checklist Benchmark & target high use buildings> 55 gallons/person/day or 83 gallons/bedroom/day Fix leaks Upgrade water fixtures:showerheads, faucet aerators, repair toilet flappers or replace pre-1994 toilets (or others using > 1.6 gpf) Specify ENERGY STAR clothes washers Minimize water for plantings:Avoid irrigation and use draught tolerant plantings

  32. Review Learning Objectives • Understand the value of tracking water usage • Identify 4 significant water usages in buildings • Identify 3 actions property managers can take to conserve water • Understand how to evaluate the cost effectiveness of water conservation strategies
