Township engineers identify several hundred feet of corrugated pipe needing lining in Aspen Drive area

Public‑works staff told the board on Sept. 18 that video inspections of corrugated metal stormwater pipes in the Marshall Creek/"Aspen Drive" development revealed significant localized deterioration.

The public‑works speaker said staff and foreman Derek Claus ran a camera truck through storm pipes and reviewed the video in the office. Staff reported inspecting between a stated 300 feet and a later corrected estimate of about 1,000 feet of pipe. From that review they identified roughly 400 feet that "is in immediate need of lining," about 450 feet that should be re‑evaluated in two–four years as deterioration progresses, and more than 900 feet judged in excellent condition and scheduled for re‑evaluation in about 10 years. Staff said a scope of work will be developed to obtain quotes for cured‑in‑place pipe lining and that funds are currently budgeted for the project.

Board members asked technical questions about life expectancy and replacement. The public‑works speaker said the lining process, when properly installed and cured, is expected to last about 50 years; full replacement would be more disruptive and costly where pipes are buried deep. Staff noted that in 2015 the township performed pipelining work in the same development at an approximate cost cited in the meeting of about $100 per foot for 500 feet.

Next steps: staff will prepare a scope of work and seek quotes for lining the identified sections and will present contract options at a future board meeting.
