Annual water use in Madison drops by a billion gallons in six years
Thursday, January 17, 2019 - 10:01am
After hitting a 50-year low in 2017, water use in Madison was down once again in 2018. Madison Water Utility pumped 9.2 billion gallons of water to homes and businesses across the city last year, about 200 million gallons less than the year before – and more than a billion gallons less than the utility pumped in 2012. It marks the 4th consecutive year water use has been below 10 billion gallons, even though Madison’s population is growing.
“We’re still adding buildings, homes, apartments,” says Madison Water Utility Chief Financial Officer Robin Piper. “People are still getting all the water they need. They’re just using it more efficiently, and thinking a little bit more about that water. Customers are doing their part to help us conserve.”
Per-capita water use for customers living in single-family homes has dropped to the lowest level in at least the last 20 years. Residential customers used 53 gallons per-person per day in 2018. Back in 1988, that number was 80 gallons per person.
The drop in per-capita water use means the City has hit its water conservation and sustainability goal set in 2006 that called for a 20% reduction in per-capita residential water use by 2020, based on a five-year rolling average.
“It’s huge,” says Madison Water Utility supply manager Joe DeMorett. “There were serious doubts we could get down to that level, actually. We were pumping well over 10 billion gallons of water a year. And to be down around 9 billion now, I think is incredible.”
DeMorett says another wet summer in 2018 meant fewer people were out watering lawns and gardens. He also points to more efficient appliances and plumbing fixtures, as well as a sharp decline in industrial water use.
“You’ve got the low-flow toilets, washing machines. And there are certain industries that have been here forever that are just gone, like Oscar Mayer and the dairies. They moved out.”
Industrial water use in Madison is down 73 percent from just seven years ago. Both Oscar Mayer and Bimbo Bakeries, two national food companies, have left Madison in recent years. Madison’s last remaining dairy operation closed its doors in 2009.
Madison Water Utility has also been working hard to encourage conservation through its popular Toilet Rebate Program, which has saved nearly a billion gallons of water since 2009. And more than 12,000 people have signed up to use the utility’s online conservation tool that allows customers to track their weekly, daily and even hourly water use.
So far in 2019, water use in Madison is down 7 percent from this time last year.
