The Colorado River meets 90 percent of Southern Nevada’s water demands. 90% 10% Colorado River Resources Southern Nevada Groundwater 9

The Colorado River is shared among seven Basin States and the country of Mexico. 10

Nevada receives 370 million m 3 of Colorado River water annually. River Allocations (in billion m 3) Colorado 0. 37 1. 85 4. 8 Wyoming New Mexico 3. 5 Utah 1. 2 1. 05 5. 4 2. 1 California Arizona Nevada Mexico 11

The Colorado River Basin is facing one of the worst droughts in recorded history. 12

Lake Mead’s water levels have fallen nearly 43 meters. Drought impacts: - Availability of supplies - Resource allocations - Water quality in the lake - Infrastructure operations 2000 Today 13

WATER RESOURCES The SNWA relies upon a mix of permanent, temporary and future water resources to meet Southern Nevada’s water demands. TEMPORARY PERMANENT FUTURE 14

PLANNING FOR THE FUTURE The SNWA maintains a 50 -year Water Resource Plan that outlines projected demands and resources over a 50 -year planning horizon. • 493 million m 3 in permanent water resources • More than 2. 2 billion m 3 is banked for future use 15

WORKING WITH MEXICO Extension of main terms of Minute 319: • Shortage, surplus, Intentionally Created Mexican Allocation • New projects and more conservation • Includes an environmental component • Supports ongoing studies (desalination) • Bridging to Drought Contingency Planning Laguna Grande Restoration Site 16

CONSERVATION Southern Nevada’s conservation program promotes the efficient use of water resources and relies on four key tenets: REGULATIONS PROGRAMS PRICING EDUCATION Development codes, watering restrictions and other local ordinances help keep the use of water efficient. Incentive programs offer rebates for water-saving technologies and practices, such as car washes, landscape removal and pool covers. Local purveyors establish water rates that send conservation signals, but remain competitive among similarly-sized western cities. Tools such as the Speakers Bureau program, Youth Advisory Council, websites, publications, social media and public access TV show help reinforce messaging. 17

More than 99% of water used indoors is captured, treated and reused. Only water used outdoors is lost. Southern Nevada can reuse water used indoors indefinitely. 18

CONSERVATION EDUCATION AND OUTREACH • Community outreach • How-to collateral (finding leaks, landscaping planning, pool and spa maintenance) • H 2 O University teacher training • Youth Advisory Council • Desert demonstration gardens and plant sales • Water Smart Innovations Conference • Springs Preserve • Mass media and marketing 19

CONSERVATION REGULATION AND INCENTIVES MANDATORY • • Landscape development codes Golf course water budgets Mandatory watering restrictions Water-waste prohibition VOLUNTARY • Smart Irrigation equipment rebates • Pool cover rebates • Water Efficient Technologies (W. E. T. ) for industrial/institutional clients • Indoor Retrofit program for older homes and apartments • Water Smart Landscape (WSL) program 20

CONSERVATION The SNWA’s Water Smart Landscapes Program has yielded remarkable water savings for Southern Nevada. 21

COMMITMENT TO WATER QUALITY The SNWA monitors water quality 24 hours a day, 365 days a year. Each year, the SNWA laboratory staff: • Collects more than 33, 000 water samples • Conducts more than 333, 000 analyses • Tests for more than 140 regulated and unregulated contaminants • Ensures that Southern Nevada’s water meets or surpasses federal Safe Drinking Water Act standards 23

SECURING A FUTURE: Intake No. 3 ensures system capacity and protects customers from water quality issues. Operations began September 2015. Project details: ‒ ‒ 4 km tunnel underneath Lake Mead Approximately 2, 400 concrete rings—each weighing 30 metric tons—used to line tunnel Hydrostatic pressure of 15 bar $817 million (€ 751 million) Intake Tunnel 24

SECURING A FUTURE: Low Lake Level Pump Station Construction has begun on a new Low Lake Level Pumping Station near Lake Mead. When completed, the pump station will ensure water deliveries down to elevation 266 meters. Estimated cost: $650 million (€ 597. 8 million) 25
