Water Main Replacement Program

Water main replacement planning is a necessary, preventative approach that saves money on repairs, reduces the loss of water that occurs as a result of the main breaks, and minimizes disruption to customers.  Des Moines Water Works budgets for water main replacement to maintain and upgrade the distribution system by replacing water mains that have a history of breaks, to improve the fire flow, relocating to accommodate city, county, or state construction projects, and upgrading water mains to meet the needs of customers.

Several factors impact which water mains are replaced and the approach to planning for 2018 was different than in years past.  Des Moines Water Works’ Long Range Plan through 2040 included the analysis of water main break data occurring within the system.  Through this analysis, a relative risk score was created based on the assessment of consequence of  failure, likelihood of failure, and a capacity factor.  Pipe segments consisting of risk scores in the highest range are highly recommended for replacement.  Staff from various departments provided input while creating the priority list of streets for water main replacement.  Des Moines Water Works’ 5-year Capital Improvement Plan (CIP) includes approximately $7 million of water main replacement each year.  The City of Des Moines also has a 5-year CIP for city streets and sewers.  Des Moines Water Works and the City of Des Moines work collaboratively to choose the streets to be the most cost effective and cause the least disruption to customers.

After each project is designed, Des Moines Water Works will receive bids from contractors and the construction contract will be awarded to the contractor that will be performing the work.  If the bids received allow Des Moines Water Works to complete all the streets within budget, construction will take place in 2018.  Construction not completed in 2018 will take place in future years.  Des Moines Water Works is currently contacting customers directly in the neighborhoods throughout Des Moines and Polk County that have been scheduled for water main replacement in 2018.  Additional customer letters and public meetings will be forthcoming.  Des Moines Water Works appreciates the cooperation and understanding from customers during construction and will work with contractors to minimize the inconvenience to customers impacted by the following projects:

Who Owns What?

Des Moines Water Works (DMWW) provides water to its customers and maintains the water mains required to deliver water to homes and businesses.  DMWW also owns the water meter used to measure consumption.

Property owners are responsible for the connection (tap) to the water main and the piping (service line) that carries water from the main to the meter.  The property owner is also responsible for protecting and providing access to the water meter.

When a problem occurs, DMWW staff will assist the property owner in determining the cause of the problem and the appropriate course of action.

Stop Boxes

What is a stop box?  The stop box houses the valve used to turn the water service on and off to a property.  It is usually located in the public right of way.  DMWW requires that the stop box be operable at all times.

Who owns the stop box?  The property owner owns the stop box and is responsible for its repair.

How does the stop box operate?  To operate the stop box, a long key is placed inside the housing and lowered onto the valve to turn the water service on or off.  Sometimes, due to age or damage, the stop box does not operate, requiring repair.

Why is the stop box operated?  DMWW will operate the stop box:

  • To terminate service at the owner’s request when a property is sold.
  • To cut water service for internal plumbing repairs.
  • At a rental property to discontinue water service when the tenant is moving.
  • When a customer fails to make timely payment on their water bill.

Repairs

What are the reasons for repair?

  • When the stop box is too high or too low.  The top of the stop box should be level with the ground.
  • If the stop box is located under concrete or asphalt, a repair must be made so that the stop box is accessible.
  • If the housing for the stop box becomes bent and the key cannot be lowered into the housing.
  • If the rod is loose in the stop box and does not connect to the valve.
  • When the valve does not operate.

Who will make the repairs?  DMWW is not licensed to make plumbing repairs and we recommend that you contract the services of a licensed plumber.  If you do not make repair arrangements, DMWW will contract the services of a plumber and bill the charges to your account.

How much will it cost for repairs?  Stop box repairs range in cost, depending on several factors, such as which part of the box needs repaired, whether the box is in concrete, etc.  Repairs can range in cost between $600 and $2,000. While boxes can become inoperable over time for many reasons, the best way to protect your box is to prevent it from unnecessary operation by keeping your account current.

Other Questions

What if my service line starts to leak?  Please notify DMWW at (515) 283-8700 if you notice water leaking and our representative will assist in determining the location of the leak.  Sometimes it is difficult to determine the source of the leaking water as it follows the path of least resistance and does not always come to the surface right near the leak.  Once located, the property owner will be notified to contact a licensed plumber to make repairs to the leaking service line.

What if my service line starts to leak and water is not coming to the surface of the ground?  During our routine leak survey of the distribution system, using electronic leak detection equipment, leaks are sometimes located that don’t come to the surface.  Our leak detection personnel will attempt to determine the source of leaking water and inform you of its general location.

Who is responsible for the water meter?  The water meter is usually located in the basement or in a meter pit outside the building.  The property owner is responsible for protecting the meter from freezing temperatures and providing access to the meter and meter reading equipment.  The water meter is owned by DMWW.

If you need additional assistance, please call (515) 283-8771.
