The Grimes Brief
The first checklist in a new house is always the same: lights, heat, water, internet. Here is who provides each in Grimes, what the city charges, and how to pay the water bill without a scam scare.
Water, sewer, and trash come from the City of Grimes on one monthly bill, due by the 20th (City Hall, 101 NE Harvey St, 515-986-3036). Electric is MidAmerican Energy (888-427-5632), gas is Black Hills Energy (888-890-5554), and internet comes from Mediacom, CenturyLink, Metronet, or Mi-Fiber, depending on your street.
Internet availability varies by street and by new subdivision, so check two or three providers for your exact address before you commit.
Fill out the city's online Request for Service to start service at an address on a specific date. Accounts are tied to the address, so moving from one Grimes home to another means a new account. Renters are asked to come to City Hall with a valid driver's license and a $100 security deposit. To end service when you move, use the city's end-service form. The utilities email is [email protected]. More on the system is in our water guide.
As a rough illustration, 5,000 gallons of water, with sewer billed on the same gallons, plus the garbage, meter, and stormwater charges comes to about $138 before any other fees. Your sewer charge may be calculated differently, so treat that as a ballpark. Irrigation water is billed at the water rate.
Paperless billing is the default on new accounts. Bills are due by the 20th. After that a 1.5% penalty and a $5 service charge for the disconnect notice apply, and the notice goes out on the first business day after the 20th. A disconnect order adds a $25 fee, and no reconnections happen after 4:30 p.m.
The city has warned that fraudulent bills pretending to be from the City of Grimes are circulating. If a bill looks off, call City Hall at 515-986-3036 before you pay it.
For a broken water main or hydrant, a service line problem between the meter and the street, a sewer backup that may involve city infrastructure, or water gushing from the street, call the city's 24/7 line at 515-985-0667. That line cannot help with billing. For billing questions, call City Hall during business hours. Sign up for text or email alerts at grimesiowa.gov/alerts. Trash questions are covered in our trash and recycling guide.
