For those single family residential customers who use large volumes of water outdoors, where it does not enter the sanitary sewer system, the utility makes lawn meters available. Customers may purchase these meters for installation in the line that feeds their outside hose tap or irrigation system.
Call Utility Billing at 228-0420 to schedule an inspection of your plumbing to determine the appropriate location for installation and any plumbing charges required. The customer is responsible for plumbing charges. Utility personnel will install the meter. Multifamily and commercial properties may apply for lawn meters, but a variance from City Ordinance 48-118 is required. Lawn meters are the Utility's way of promoting a greener community.
To protect the water system and its customers from chemicals and other contaminants that might inadvertently be introduced into the water through customer plumbing are the responsibility of the Utility Inspector. Certain plumbing devices and configurations are required to keep the contaminants in boilers, irrigation systems, aspirators, chemical and recycle tanks and other water-fed devices from finding their way into the water system.
The city is charged by State law with verifying that appropriate protection is in place and maintained on the customer's premises. If you have any questions concerning backflow protection contact the Utility Inspector at 228-0444. If installing an underground irrigation system, contact the Utility Inspector to schedule an on-site inspection of the backflow protection that must be a part of such systems. Water piping must be protected from freezing. Pipes in garages or crawl spaces should be protected with heat tapes or insulation.
Utility maintenance personnel use hydrants to flush watermains in the City. Flushing helps to clear corrosion and other deposits from the pipes, and keep them delivering at maximum capacity. In unlooped sections of the system it draws fresh water into areas where low usage may allow it to become stagnant. Finally, flushing is one of the best tools for verifying that the pipe network is functioning properly and that an unseen problem has not compromised its performance.
Personnel flush a different section of the system each year between June and September. The large volumes of water that are moved at high velocity can lead to some discoloration of the water that reaches nearby homes. It will usually clear after several minutes of running the tap wide open. If it does not clear, please call 906.228.0444.
Many buildings in the Marquette area are plumbed with galvanized iron pipe. After 15 years of service, the carrying capacity of such pipe may be reduced by up to 50% by internal corrosion. Over longer periods, the capacity is further reduced and the supply may eventually prove inadequate for some appliances or families. Under such circumstances the service line from the main into the building, and sometimes the building's internal plumbing, may require replacement.
If the volume of water available from your service seems inadequate, you may schedule an evaluation of its capacity by calling the city water distribution at 228-0444. Each year, several dozen of the worst service lines are replaced. The city will replace the portion of the line under the street right-of-way but requires property owners to install a new line from the property line to the meter. Type K copper tubing is used for the city's portion of the line with 1" diameter the minimum size installed.
