What the work involves

  • Digging trenches in the pavement, installing new pipes, refilling the trench and restoring the pavement, etc. in the work area.
  • Meters serving residents and businesses along the new lines will be connected to the new pipes after they are tested and approved for use.

How the work may affect  citizens

Traffic and access: During work on Hillsborough and East Rosemary, we will close the street to through traffic except for buses from 9 AM to about 4 PM on Mondays through Saturdays.

Residents and businesses in the area closed to through traffic will still be able to get to their locations except when a pipe is installed in front of a driveway.

During work on Henderson Street, our contractor typically need to close one lane of the roadway near our work area, but there may be times when both lanes may be closed.

We will maintain access for emergency vehicles throughout the project.

Driveway access: Will be affected when a pipe is installed in front of a driveway. Our contractor will notify affected residents/businesses before driveway access is affected.

Road conditions: After new pipe is installed at a given place, our contractor will install temporary asphalt, which will not be as smooth as the final layer to be added at the end of the project. The road will therefore be bumpy and we recommend driving more slowly than usual. To limit costs, we will restore the pavement in our work area rather than the full width of the street.

We will need to temporarily interrupt our service when we connect the new pipe to our meters and to existing water lines. We will notify customers 1 to 2 days before interrupting service.

If there are unplanned interruptions of utility services, we will work with the utilities involved to restore service as soon as possible.

There will be noise and mud, but our contractor will comply with the Town’s noise ordinance.

Our drinking water may be discolored or have air bubbles (which make water look milky) during our work. If this happens, please run cold water in a bathtub, etc. for 5 to 10 minutes. If this does not clear up the water, please call us at 919-968-4421 (24 hour number).

How to handle the normal expansion or increased pressure of water when it is heated in a plumbing system.

In water line replacement projects, we add devices to prevent water from flowing backward from private plumbing through our meter and into our public water system. These devices are needed to help protect the public water supply from potential contamination.

 

 

 

 

 

 

 

 

 

 

Above: A thermal expansion tank is one way to handle the expansion of water when it is heated

When water cannot flow back through our meter, pressure in your water pipes may increase due to the normal operation of a water heater. When heated, water will expand or its pressure will increase if the water has no room to expand. For more information about devices to handle the expansion of water when heated, please click here.

OWASA does not require you to install a device for thermal expansion, but we want you to be aware of the potential need for one. We recommend getting advice from a plumber about whether to install a device to handle thermal expansion.

Updates: After work begins, we will send updates and post them on our webpage about once a month, but we will e-mail notices about traffic changes, etc. to people in affected areas whenever needed.

Comments or questions? Please feel free to contact Jeremy Fireline, P.E., Project Manager, at 919-537-4249 or jfireline@owasa.org whenever you have any questions or comments.

If you have renters at your property/ies near our project, please ask them to contact us if they have questions or comments or wish to be on our distribution list for future updates.

We ask for and we thank you for your understanding and patience during our work to maintain reliable water service.
