Summer Irrigation Watering Schedule

Summer Irrigation Watering Schedule
Posted on 08/26/2020


Due to the continued drought and high heat conditions, we are seeing record water use in our community. Des Moines Water Works has also seen water use increase over 30% from last week. To lessen the water demands, and our future water rates, we are asking residents to consider not irrigating their lawns. If you still wish to irrigate, we ask that you follow the irrigation schedule.



Norwalk is part of a Metro-wide water system. One of the most significant costs within our water system is maintaining enough capacity to supply water for irrigation. Irrigation is something that generally happens only five or six months out of the year with heaviest usage in a 30-day period. Imagine the cost of creating a water system that must supply and have capacity for water that is double typical daily usage on a winter day, yet half the revenues to pay for that maintenance.


Norwalk peak day water usage - 1,950,000 gallons

Norwalk typical day usage mid winter - 750,000 gallons


Metro communities continue to see increased costs for system expansion and maintenance. We are looking to our citizens and businesses to help us make a difference. This focus is on those customers that have irrigation systems. We are looking for your help to flatten the curve of water usage. If you can set up, or change, your watering schedule per this flyer, you could help us make a difference. This type of watering schedule would help prevent the City from implementing an irrigation surcharge to help offset costs for system improvements/maintenance. Today metro cities are looking at a 25% increase in irrigation rates to help address these system expenses (i.e. building a new water tower at $6 million).


We love community pride and the look of a well manicured lush lawn. What we love even more are reasonable water rates for all customers.
