case study

Municipalities throughout Illinois have been making determined efforts to conserve water though policy changes, education, outreach, and water-loss reduction strategies. The Illinois Section of the American Water Works Association (ISAWWA) Water Efficiency Committee and IISG assembled seven case studies from the ISAWWA Water Saver award applications to highlight water efficiency achievements. Evanston is our first story.

Evanston, a city of 74,500 that sits along Lake Michigan north of Chicago, developed a Water Conservation and Efficiency Plan through a grant from the  Chicago Metropolitan Agency for Planning Local Technical Assistance Program.
 
Community water efficiency and conservation plans are recommended in the Water 2050: Northeastern Illinois Water Supply/Demand Plan as a cost-effective strategy to ensure continued water availability in the face of growing regional water demands.
 
As a result of this plan, Evanston began to educate residents on how to reduce wasted water. It distributed  toilet leak detection testing kits, promoted WaterSense-branded bathroom fixtures, and encouraged drinking tap water. Evanston provided 9,300 gallons of tap water at city-sponsored events in 2014, eliminating the use of over 99,000 plastic 12-ounce bottles.
 
In addition, Evanston purchased new leak detection equipment and has completed a survey of the distribution system. The entire 157 mile system will be surveyed each year to minimize water loss due to aging water mains.

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.Watch the 3-part video series at the link in bio.(Photo credit: Liz Spitzer, Illinois State Geological Survey, Coastal Research Group)
Managers and researchers can be faced with a need to classify the risk of new crayfish invaders. Rapid assessment tools, such as the Science-based Tools for Assessing Invasion Risk (STAIR), can assist in this process by providing a streamlined framework for analysis and decision-making.Join us for an ICC webinar with John Bieber from Loyola University Chicago to learn how rapid assessment tools are used to classify invasive species risk and how STAIR can support invasive crayfish management.Learn more at the link in bio.
