CIPP Lining Project Cured-in-Place-Pipe Lining (CIPP) involves inserting a flexible liner inside the existing pipe, inflating the liner, and exposing it to heat or ultraviolet light to dry and harden the liner inside the pipe. The liner forms a smooth surface inside the existing pipe, restoring it to near-new condition. The City’s total sewer system is 49.6 miles and consists of various pipe materials. Currently, 16 miles of pipe have been lined by CIPP, with 15.5 miles that are candidates for lining in the future. The remaining 18.1 miles are made of plastic (PVC), so the lining is unnecessary. The City is planning a CIPP lining project within the Arden View Drive neighborhood off Hamline Avenue. The lining of the existing 8-inch VCP pipe is expected to be roughly 5,700 feet. This process is a much more efficient and cost- effective way of rehabilitating the sanitary sewer mains underneath the streets without major impacts or trenching operations. Before any work occurs in the sanitary mains that your home may be connected to, the contractor will place door hangers a couple of days ahead of the work with more information. Some of the information it will include are the dates that the work will be performed, coordination with the building residents with their sanitary sewer service traps (which you will need to be sure have sufficient water), an explanation of their process, plus more useful information to review. The pipe lining process includes an epoxy resin that adheres the new liner to the existing sanitary main. The new liner will emit a glue-like smell while it is being installed, so it is important to follow all of their instructions when filling up water into your sanitary sewer service trap. Otherwise, the smell can inject itself into your home through your sanitary service. Impacts outside your home typically last 1-2 days. Some large trucks will be parked in the middle of the streets to access manholes for cleaning, prep work, and lining, but for the most part, this will be fairly unimpactful. Contact information for the project will be shared as we get closer to the start of the project.
