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.

Algonquin is the third story in our series.

Rapid population growth is forcing Algonquin, Illinois, a city of about 30,000 located 40 miles northwest of Chicago, to reevaluate its water use strategy.

The village developed its initial water conservation program in 2003 at a time when the system was significantly strained. It included outside watering restrictions, public outreach, operations improvements, and a seasonal water rate structure. The program was a success, resulting in a water use reduction of roughly 30 gallons per person/day.

Because ongoing population growth in the village is expected to put upward pressure on water demand, Algonquin’s next step was to update the Comprehensive Water System Master Plan to evaluate the potential of further water conservation efforts to meet long-term water demands. The goals were to evaluate overall water system performance, evaluate current patterns of water use, predict future patterns of water use, and determine the infrastructure necessary to use less water resources.

While stewardship and sustainability are the main drivers of water conservation in Algonquin, village leaders also wanted to understand how an effective water conservation program can result in a reduction in capital expenditures through the timing of capital investments.

The Village of Algonquin Comprehensive Water System Master Plan was completed in 2012 by Engineering Enterprises, Inc. As the plan moves forward, the savings will be significant.

When comparing current water use trends and potential less resource intensive scenarios, the planners found a nearly $6,360,000 capital cost difference and showed that water conservation policy can have a huge impact.

“The Master Plan has been a great resource to refer back to,” said Andy Warmus, Algonquin utilities superintendent.

“I use the document in some fashion every day.  Can’t imagine not having the information at our fingertips.”

The Great Lakes, a source of freshwater for millions in American and Canada, will likely see increased stress as the water is needed for a growing population and a changing climate.

From The Toledo Blade:

“The Lakes’ usage has drawn more attention in recent years from politicians and legal scholars, such as those who attend the University of Toledo College of Law’s renowned Great Lakes water-law conference each fall. They have stated on numerous occasions that Great Lakes water-management laws pale in comparison to those of the American Southwest, where political battles over water rights have been fought for decades.

 

Scholars believe this region’s legal framework is evolving into a stronger one as water controversies and more political battles heat up, as evidenced by intense negotiations that resulted in the Great Lakes region’s first binding water-management compact.

 

The Great Lakes region has traditionally been less irrigated than others. But that too is changing.

Large portions of both Illinois and Indiana continue to experience very low rainfall and drought conditions, and many homeowners are wondering what to do about their lawns. With water in high demand, several  communities place watering schedules or restrictions in effect in order to conserve the available water. But what to do about your lawn? 

“’If your lawn is brown, it’s not dead,’ says Richard Hentschel, a University of Illinois Extension horticulture educator based in St. Charles (urbanext.illinois.edu/hort). ‘The grass has just hunkered down into survival mode. The plants have stopped growing and given up on their leaves to conserve water and are concentrating all their resources on keeping their roots and crowns alive.’”

“Lawns are easily replaced, but trees are not. Even large trees need help to survive a drought – and if they die, it can take 20 or 30 years to replace that shade. Stress from the 2005 drought killed trees over the next several years. So put trees at the top of the list for watering.

 

Let the hose trickle for a good long time in several places under the tree’s canopy. Or spiral a soaker hose loosely around a tree trunk. Or buy a soaker bag at the garden center that will slowly ooze water to the roots. Most of a mature tree’s roots are within 6 to 8 inches of the soil surface.”

Conserving water has always been important for a number of reasons, but recent studies are showing that it’s a serious issue. As the need for water grows worldwide, the way that we use water requires some significant consideration, study, and action. 

“Water is reused in two main ways: non-potable reuse, in which treated wastewater is used for agriculture and landscape irrigation, industrial applications (such as cooling processes), toilet flushing and fire protection; and indirect reuse of wastewater to recharge ground water supplies, allowing treated wastewater to percolate down to aquifers and replenish water sources. Overall, non-potable and indirect reuse of water in the U.S. is growing rapidly, with more than 2 billion gallons reused per day, and volume increases at an estimated 15 percent annually.”
