Des Moines Water Works has asked customers to voluntarily conserve water as drought and near-record water demand strains supply.
On Monday, the utility asked metro residents to reduce their lawn watering by 25%. The utility has a capacity of 110 million gallons a day however, when demand reaches past 90 million the system risks water pressure problems. On June 9, Water Works pumped 88.6 million gallons, now the second highest peak since 2012 when 96 million gallons were pumped.
In an interview with the Iowa Capital Dispatch, CEO Ted Corrigan noted if it doesn’t rain soon, the utility may need to ask for a 50% lawn watering reduction. This is only the second time during Corrigan’s 31 years at Water Works that the utility has asked customers to voluntarily reduce water usage. The last time a cutback was encouraged was in 2012.
Water Works has had to lower its usage of the Des Moines River due to toxic algae issues which re-emerged a month early this year; making the river unusable. The current main source of tap water, the Raccoon River is running at 7.5% of its median flow.
Over the past decade, Iowa has spent over $40.6 million at six locations to treat and prevent algae toxin outbreaks. Nationwide, this issue has become a $1.1 billion issue according to a study by the Environmental Working Group.
The request impacts Des Moines, West Des Moines, Johnston, Urbandale, Clive, Norwalk, Pleasant Hill and Ankeny city residents.
