Frequently Asked Questions

Q. How do I report a water main break?

If you notice water bubbling out of the street or boulevard contact the Public Works Department at 952-939-1382.

Q. What do I do if I think I have a water leak?

Call 952-939-1382 and schedule a time for someone to check your house for leaks.

Q. What is the hardness of the City's water?

The City's water is 21 grains of hardness. The level of magnesium and calcium in your water determines the hardness.

Q. Why is my water brown?

The City of Hopkins filters iron out of the water before it reaches your home. After the water is filtered the remaining iron content is .03 parts per million. Even though the City filters out the iron, some iron still remains in the water and coats the inside of the water main pipes. Your water turns brown because of the release of these mineral deposits, caused when large amounts of water are pulled off the system either by hydrant flushing, water main breaks, water service leaks, or the Fire Department.

Q. Where can I find out about water quality in Hopkins?

See Water Quality. The City also publishes a water quality report every spring in the Highlights newsletter.

Q. How much water do I use when I flush my toilet?

It depends on your toilet. On average, you use 5 gallons of water when you flush your toilet. New low flush toilets use 1.5 - 2 gallons per flush.

Q. Do I use less water when hand washing dishes or when I use my dishwasher?

A full cycle on a dishwasher uses 15 gallons of water. On the contrary, when you hand wash your dishes and leave the faucet running for rinsing, you use 20 gallons of water.
