Sewer renewal east of Manning Drive

In July, a contractor working for OWASA  started work to renew part of our sanitary sewer system as shown in the map below.

This work may last about six weeks, but weather and other conditions may affect the start and completion of work.

The purpose of this project is to prevent wastewater overflows from our sewers by resealing the inside of sewers to keep stormwater and groundwater from getting into and overloading the sewers.


How the work may affect you

  • Some parking spaces near Boshamer Stadium will not be available when work is done in the parking area.
  • There will be noise from construction vehicles and pumps in the work area. Our contractor’s normal work hours and days will be 7 AM to 6 PM, Monday through Friday.
  • There will be temporary sewer piping on the ground in work areas. Pedestrians and drivers should avoid work areas and use alternate routes if needed.
  • When the new lining in a sewer hardens, you may notice odor for a day or so. The fumes are not toxic. To keep the fumes from rising through plumbing drains for your home, please make sure that water is in the “P traps” under toilets, sinks and other drains. You can flush a toilet or pour water into a drain to fill the P trap. Please see additional information about P traps below.
  • No interruptions of utility services are planned. If there are unplanned interruptions, we will work with the utilities involved to restore service as soon as possible.

What is a P Trap?

A P trap is a U-shaped section of piping under a sink, toilet, drain, etc. which normally holds water and keeps gas in plumbing drains and sewers from rising through the drains into a home or other building.

A P trap may get dry in a toilet, sink, etc. if there is a leak in the P trap or if it is not used for a long time and water evaporates from the P trap.

If a P trap is dry and does not leak, you can refill it by pouring water into a drain or flushing the toilet if there is water in the tank.

A leak in a P trap should be repaired so that it will work properly.
