1 Investing In Water: Business Opportunities in Water Efficiency Rob Zimmerman, LEED-AP Sr. Channel Manager Sustainability Kohler Co. Doug Bennett Water Conservation Manager Southern Nevada Water Authority

2 Perspective on Water Conservation Water conservation is one of the critical issues facing our society today and continues to grow in importance. - Human Health & Recreation - Habitat Preservation - Economic Development - Cost Savings

3 Perspective on Water Conservation Benefit: Economic Growth & Cost Savings - Water rates continue to rise (+9.4% in 2012) - Energy and material costs continue to rise - > 90% public water utilities expenses = infrastructure - AWWA: $200 billion - $1 trillion in next 20 years on water systems

4 Water Supply & Demand Water Conservation Hot Spots Seattle San Francisco Bay Southern Nevada Southern California Arizona New Mexico South Texas Denver area Boston area New York City Washington DC area Chicago area Atlanta area Coastal Carolinas South Florida Caribbean islands

5 Demand: We Don t See Most of the Water We Use

6 Water Demand Although plumbing products only use 3.7% of all available water in the US, it uses the most expensive water potable or treated. US Total Water = 408 bgpd Potable Water = 47 bgpd Residential = 13.7 bgpd Indoor Plumbing = 15 bgpd Commercial = 1.4 bgpd

7 Water Demand: Residential U.S. Potable Water Consumption Average Residential Indoor Water Use: 69.3 gpcd Average Residential Outdoor Water Use: gpcd, depending on region

8 Opportunities for Plumbing Contractors Opportunity Fixture Retrofits Water Reuse Leak Detection and Repair Rainwater Storage and Transfer Smart Meters Estimated Value $7.5 bn (labor only) $4 bn/year (US only) $20 bn/year (worldwide) $1 bn/yr (2016 est.) $400 mil/yr Repairs >> New Construction Pipe fitters, engineers, mechanical contractors, product manufacturers

9 Opportunity: Fixture Retrofits Retrofits - Make physical changes that don t require consumer behavior change Replace Old Toilet or Urinal with Water Efficient Model Install Low-Flow Aerator on a Faucet Repair Leaks Install Water Efficient Landscaping - Proven long-term water savings - Savings are predictable & measurable

13 Water Efficiency Codes & Programs Drainline Carry Considerations - Drain sizing and slope - Cumulative effects of less water - Plumbing code changes - Retrofit recommendations

14 Opportunity: Water Reuse Water Reuse: Reclaimed Water - Municipal wastewater is further treated, then used again - Not drinking water - Major uses are: Irrigation Groundwater recharge Cooling towers Process water Toilets and urinals

15 Opportunity: Water Reuse Showers Toilets Baths Kitchen Sinks Bathroom Sinks Dishwashers Clothes Washer Graywater = wastewater that has a low bacteria, chemical, or solids loading Blackwater = wastewater that has high bacteria or high organic content

16 Opportunity: Water Reuse Graywater Factors to Consider Single-Family Home System Commercial System - Water must be pumped to point of use - Separate drain lines and storage - Minimal indoor use (toilet/urinal flushing) - NSF 350 water quality standard now finalized - Not allowed in all areas - Poor ROI - Requires maintenance

20 Colorado River Serves about 30 million people in 7 states and Mexico Irrigates 3 million acres of farmland (over 70% of water use) Allocations exceed average flow by 15-20% Climate change may reduce flows by 5-15% Current storage about 50% of capacity Provides 90% of Southern Nevada s Water

21 The Colorado River: Imperiled? Southern Nevada uses just 1.8 percent of the water allocated from the Colorado River, but it constitutes 90 percent of our supply.

22 Indoor vs. Outdoor Water Use 10% groundwater TREAT 90% Surface water All water used indoors is recovered for direct or indirect reuse. 70% of Las Vegas structures were built with water efficient fixtures

23 Demand Management Tools EDUCATION WATER PRICING REGULATION INCENTIVES The SNWA and its member agencies utilize a variety of tools to promote conservation and reduce overall water use.

24 2012 Municipal Metered Water Consumption Use By Customer Type Common Areas HOAs, 5.7% Other, 1.7% Schools/Govt/Parks, 5.8% Golf Courses, 6.5% Residential (SF), 44.5% Resorts, 7.7% Commercial / Industrial, 12.4% Residential (MF), 15.7% Notes: (a) Municipal metered water consumption billed to customers from all sources (potable and non-potable). (b) Potable includes ground water and Colorado River water (c) Non-Potable includes raw Colorado River water, reclaimed and reused water (d) Reflects the service areas of all SNWA agencies providing potable and/or reclaimed water.

25 Regulation: Landscape Development Codes Lawns are prohibited in new residential front yards and limited to 50 percent of the landscape area in new backyards. Clark County Operations Building

26 Regulation: Landscape Development Codes Lawn is prohibited in new non-residential developments. Clark County Operations Building

27 Regulation Golf Courses Existing golf courses are subject to water budgets based on irrigated acreage. Surcharges apply to overuse. Siena Golf Course Golf courses have converted more than 35 million square feet of grass to water-smart landscaping.

49 Energy, Water & Carbon Las Vegas pumps a ton of water per person per day. 1,000 gallons requires 6.5 kwh to treat and deliver. One kwh requires 0.5 gallons of water. One kwh discharges almost one pound of CO2. Without water efficiency, an additional 500 million pounds of CO2 would be discharged annually.
