[ARCHIVED] What's Happening in Willowbrook Park?

What’s Happening in Willowbrook Park?

The City of Burlington is in the process of installing liners in the sanitary sewer pipe system in five locations throughout the City. This “NO-DIG” technology is being used for the rehabilitation of sections of pipe in the following areas: Willowbrook Park, Chandler Avenue, Hawkins Street, Ruffin Street and a continuation of Willowbrook on Church Street. After evaluating these areas it was necessary to undergo this process. The current pipes were deteriorating and water infiltration during heavy rains was becoming an issue. A layered felt liner impregnated with heat-activated resins will be inverted into the existing pipe and filled with water. Lines are then connected to a portable boiler unit which heats the water in the “new pipe” to set the resins and form a cured in place structure within the host pipe. During rehabilitation work on a section of pipe, the normal flow thru the pipe is diverted using by-pass pumping. The original pipe will lose some diameter, but will gain capacity thru improved flow characteristics within the new pipe. The end result will reduce inflow and infiltration into the sanitary sewer system resulting in reduced expenses at the City’s waste treatment plants for the treatment of storm water.
