City staff urges 50% voluntary irrigation cuts as daily water use spikes above 4 million gallons

Waukee — City staff asked residents to voluntarily cut irrigation by half amid high seasonal water use and elevated nitrates in source supplies, noting recent daily usage spikes that strain treatment capacity.

A staff presenter, Steve, said the city remains in phase two of a regional water conservation plan and clarified the request applies specifically to irrigation, not overall household use. "On average in the city of Walke on a daily basis, we use roughly 1.6 million gallons of water," Steve told the council, and he said that during a hot day last week the city recorded usage above 4 million gallons. He added that irrigation is the primary contributor to large daily spikes and that curbing irrigation should help the utility maintain supply for drinking, bathing and cooking.

Why it matters: Staff framed the irrigation reduction as voluntary but important to prevent escalation to mandatory restrictions. The report noted elevated nitrates in source waters as a complicating factor for treatment capacity.

What staff asked residents to do: Steve asked for a 50% voluntary reduction in irrigation use and said the city hopes that, combined with recent rains, residents will avoid irrigating this week to reduce demand.

Other notes from staff: The presenter also reported on an employee safety luncheon focused on mental health and community events including Walk Palooza and movies in the park. The council adjourned after brief additional announcements.

Next steps: Staff will continue to monitor daily use and offer further guidance if voluntary measures are insufficient.
