Lining Project

The relining of the existing sanitary and storm sewers is getting done as a part of another project; the general contractor is Insituform Technologies. This work might commence this week with the cleaning of the sewers. While the actual lining process is taking place, Insituform will ask residents to limit their water usage by limiting the use of the toilet and refraining from doing laundry. Insituform will notify residents when this needs to be done.

The sewer lines are rehabilitated by a resin-saturated felt tube that hardens into a strong "pipe within a pipe". A chemical called styrene is used in the resin and can emit a strong odor that smells like new plastic. It is possible that residents may notice this odor as work is being done. Insituform first suggests that residents close all toilet lids. If the odor is present in a resident's house, Insituform suggests ventilating the house by opening windows and doors. The release of styrene during the typical sewer rehabilitation process does not pose a significant risk to human health or the surrounding environment. However, exposure to high concentrations of styrene should be avoided.
