To serve you better, we've assembled a list of our customers' most frequently asked questions. If you don't find your answer here, feel free to contact us.

Why do I receive a bill from Missouri American Water Company ?

Missouri American Water Company purchased the City of Arnold's sewer system and they are now your sewer service provider. This is your wastewater (sewer) bill and not your water bill.

What do I do if I am experiencing low pressure?

Check your meter and the surrounding area for possible leaks. Check with neighbors to see if they are experiencing low pressure, check other faucets to see if problem is throughout the whole house or just one faucet, if whole house you may have a bad pressure regulator. If you can't determine problem, call our office and report low pressure for your area.

How could I have used this much water?

You could possibly have a leaky toilet, faucet or service line between the house and meter pit that's difficult to detect. Just call the office and we'll work with you to solve the problem.

Why do I have a previous balance when I know I sent in my payment?

We may have received it after the due date or we may not have received it at all. Call our office and we will help you solve the problem.

Why is my water discolored?

A repair could have been completed recently allowing air to enter the line, causing the milky look.  Let your faucets run for a few minutes to work air out of the lines.

What chemicals does our utility district add to the water?

We do not add any chemicals, our source of water is purchased from Missouri American Water Co. and they use only chemicals that are approved by the National Safety Foundation for treatment of drinking water.

Why does debris come out of the faucet when running hot water?

Most likely your water heater needs to be flushed. CAUTION: Most manufacturers recommend hiring a professional to flush your water heater. If you plan on doing this yourself, read the owner's manual to keep from being hurt and or damaging the water heater.

Why do I need to send a picture of my water service line to slim@pwsd1jeffco.org?

Our public water system is conducting a lead service line inventory. Although we have no reason to believe there is any lead in our system, the inventory is required by the Environmental Protection Agency (EPA) Revised Lead and Copper Rule. In performing the lead service line inventory, we need to know the material composition of both the publicly owned (water system-owned) and privately owned (customer-owned) portions of the service line. We are requesting your help in this identification process. For more information and to complete our survey, click HERE
