Houston Public Works began a sanitary sewer rehabilitation project in Sherwood Trails March 9. The purpose of the project is to improve flow and maintain community property. A trenchless method is being used to minimize excavation at the construction site.
The rehabilitation of the sanitary sewer lines will be done through sliplining and pipe-bursting methods. Pipe bursting is a trenchless method of replacing buried pipelines (such as sewer, water or natural gas pipes) without the need for a traditional construction trench. An expanding device called an expander head, which may be either pneumatic or hydraulic is introduced into the defective pipeline through a launching pit. As it travels through the pipeline toward the receiving pit, it breaks the pipe into many small pieces, pushing the pieces into the surrounding soil. New pipe is attached to the back of the expander head, replacing the line immediately.
So far, crews have completed approx. 18,398 linear feet of 8-inch pipe bursting on Hermitage Hollow Lane, Tinechester Drive, Shadbury Court, Friarwood Trail, Stagdon Drive, Meandering Trail, Sherwood Hollow Lane, Chanay Lane, Sweet Gum Trail, Longleaf Pines Lane and Foliage Green Lane. Crews have completed all 4,895 linear feet of 21-inch CIPP. The project is 66% complete and is expected to be complete in early 2021.
Construction activities are expected to take place 7 a.m.-7 p.m.; Monday-Thursday. The contractor will be placing door hangers on each door at least 48 hours prior to construction beginning on the respective street. These door hangers contain important information about what to expect when construction does take place on their street. Residents are encouraged to take before and after photos of their property if it is impacted by the project.
As a result of the construction activities, be aware of flagmen and orange traffic cones that will be put in place on site to help with traffic flow through the construction zone as temporary lane closures are expected. Residents may experience an increase in noise levels due to trucks and equipment in the area.
