General Information

Charlotte-Mecklenburg Utility Department (CMUD) is installing a new sewer pipeline along McAlpine Creek from the McAlpine Creek Wastewater Treatment Plant to Lawyers Road. This project will enhance system performance, provide increased sewer capacity for present and future needs, and protect the water quality in McAlpine Creek. Phases 1 and 2 are complete.

What causes sewer spills?  Kitchen leftovers (oil, grease) and tree roots cause more than 70% of sewer spills.

Phase 3 - Under Construction.

Construction Activities to Expect

Surveying – Crews may enter easements to mark trees for protection or removal. Orange fencing will be placed to mark existing gas lines. Erosion control fences may also be put in place.

Clearing – Trees, shrubs, bushes and other vegetation within the construction easement area will be removed. Tree stumps will be removed and holes filled. Some debris will be transported off-site and some shredded into mulch.

Blasting – Crews may encounter rock while installing pipe along the route. If rock cannot be excavated by traditional methods, these sections of rock will need to be broken by blasting with small amounts of dynamite. Controlled blasting occurs underground in holes drilled into the rock. Blasting is a standard construction procedure and will be monitored with seismographs to help minimize earth vibration levels.


Safety Precautions Around Construction Zones

Throughout construction, the safety of residents along the route is of the utmost importance.
 
To limit truck traffic in the surrounding area, trucks delivering pipe and materials to crews will be allowed to access the sewer route only from designated entry points.
 
Regular work hours, except tunneling, will be limited to a 10-hour period between 7 a.m. (sunrise) and 7 p.m. (sunset) Monday-Friday, excluding Charlotte holidays. Crews will follow the City of Charlotte noise ordinance.


Why is this project necessary?
Improvements will increase sanitary sewer capacity to meet current and future needs. These pipes will reduce the risk of sewer overflows and protect water quality in McAlpine Creek.

Will my water or sewer services be disrupted during construction?
Disruptions to water and/or sewer services are not expected. If a service interruption becomes necessary, affected customers will be notified in advance.

How will I know when construction is nearing my property?
Charlotte-Mecklenburg Utility Department will reach residents and property owners through letters, email updates via website "notify me," and public meetings. If you have general questions about our engineering projects, email us or call 704-399-2221.

Will traffic be impacted?
The existing sewer lines are built along McAlpine Creek so the majority of the work will not impact roadways. When the pipe improvements must cross a street, engineers have planned for many of the major thoroughfares to be tunneled so traffic is not disrupted.

How will area be restored?
After the sewer line is activated, contractors will complete final restoration along the route to repair areas disturbed during activation. This includes:

  • Grading the soil
  • Reseeding grass / applying straw mulch
  • Installing permanent fencing that was removed for construction
  • Restoring creek banks
