Overview The Technology Campus Initiatives Water Issues Water Reuse

Water: The Lynchpin to University Life Solutions for a Range of End Users

Sustainability Efforts on University Campuses But what about water?? Water use ROSE 9% in 2010 Laundry optimization Low-flow fixtures Motion-sensor toilets Waterless urinals Green infrastructure Rainwater and grey water reuse

Virginia’s Water Apocalypse Risks: Rates, Availability, Infrastructure, Environmental Pressure Only 5-10% of “drinking” water produced will be used for consumption. Only 5-10% of “drinking” water produced will be used for consumption. History of drought in Virginia

Water in Richmond, VA Water is the lifeblood of metro Atlanta. We need it to live. We need it to thrive. But we live in the headwaters at the top of the watershed. Ninety-nine percent of our water comes from small rivers and streams, with only two large reservoirs. And, our water resources are shared by many other users as it makes it w to the coast. That’s why using water wisely is so important. Atlanta Regional Commission. Water Conservation

Environmental Pressure Water problems upstream affect those downstream as well Water is the lifeblood of metro Atlanta. We need it to live. We need it to thrive. But we live in the headwaters at the top of the watershed. Ninety-nine percent of our water comes from small rivers and streams, with only two large reservoirs. And, our water resources are shared by many other users as it makes it way to the coast. That’s why using water wisely is so important. Atlanta Regional Commission. Water Conservation Richmond’s CSO system is the largest in the state Because Richmond is downstream from Lynchburg, our water requires more treatment. James River is an impaired water way.

Richmond Water & Sewer Rates Combined rates are rising by an average 9% annually

Comprehensive Water Management Impactful Water Management Solutions Primary Treatment Stage 1 Stage 2 Reuse System Filter & Disinfectio n Stormwater Management Water Reclamation & Reuse Water Conservation Efficiency Environment Compliance Community Cost

2012 Water Use by Type: Typical University 42% Considered Non-potable Demand Cooling Irrigation Domestic/ Sanitary Domestic/ Sanitary Over 442 Million GPY

A more sustainable water cycle… Decentralized Reclamation and Reuse Before After

Solution: Reuse Water Eliminate Risks, Save Money and Increase Sustainability Cost Savings Discounted water rates Reduced potable water intake Reduced sewer fees Environmental & Social Decreases diversion of water from ecosystems Decreases wastewater discharge Net energy efficiency gains Reclaimed water shows no danger to public health Operational De-risks operations with an alternative water source Protects against mandatory conservation programs

Reclaimed Water in the News Reuse is becoming the norm, not the exception

Risk Mitigation N+1: Reliable and Safe Alternatives to Potable Water Provides Organizations with: Redundant Water Supply –Drought –Municipal infrastructure failures Additional On-Site Storage Flexibility & Resilience Independence Availability in the event of failure Minimum recovery time Insulation from rising water costs Drought Rising Rates Aging Infrastructure

Benefits Lasting benefits to campus and community In addition to providing a guaranteed water supply during the hottest, driest months of the year, reclaiming and reusing water on- site has a positive impact on surrounding communities by: Reducing risk for water shortage and drought. Diminishing demand on community resources. Deferring capital improvements & expansions. Enabling campus growth without increasing water demand. Protecting water quality (less phosphorous & nitrogen discharge). Enhancing utility reliability with alternate sources of water. Providing student engagement, academic & research opportunities.
