Newer UV Technology Speeds Project, Reduces Cost and Disruption
In early September, Baltimore County’s Department of Public Works began relining sewer pipes in Richlyn Manor, a Perry Hall community east of Belair Road.
The project, costing approximately $1 million and scheduled to be completed by spring 2016, will employ ultraviolet light technology on more than two miles of deteriorated sanitary line.
“This project will improve the reliability of an aging infrastructure system in Perry Hall,” said 5th District Councilman David Marks.
Process Easier on Residents
The County’s contractor, Pleasants Construction, Inc. will begin by cleaning sewers on Richlyn Drive, Cross Road, Carlyn Road, Gunforge Road and several smaller, adjacent streets. Crews will then insert fiberglass liners into the pipes. The liners are permeated with a light-activated resin which hardens when exposed to specific light spectra. With the liners in position, a series of high-intensity ultraviolet lamps, set on spokes and mounted on wheels, will be fed through the pipes. As the equipment moves along the conduits, ultraviolet rays will cure the resin, hardening it to a durability difficult to obtain by chemical reaction. This UV curing is similar to a current dental procedure which uses UV light to cure a cavity filler.
The new light-cured liner, which is a relatively new addition to the arsenal of techniques for pipeline repair, is corrosion resistant, durable and cheaper than new, replacement pipes which would require excavation. It is also easier on residents who will live through utility work this winter (most of it out-of-sight) while the system is being improved.
10-Month Project Affects Abbie Place Area South of Liberty Road and Milford Mill Academy
The Department of Public Works will replace one mile of sewer line in the Milford Mill area starting this month. Utility crews will begin with the replacement of an obsolete line running through Abbie Place (south of Liberty Road and Milford Mill Academy) on or about the last week of July. They will continue through a service drive along Liberty Road and then progress along parts of Washington Avenue and Lynn Haven Drive. The project should take about ten months and be completed by next summer, with crews finishing at the intersection of Lynn Haven Drive and Ripple Road.
During construction, which includes relocating other utility lines in Abbie Place, parts of the route will be intermittently closed to traffic. Some of the work on Liberty Road and Washington Avenue will be done at night. Detours, when required, will be posted.
The Abbie Place Sewer Relief project is part of Baltimore County’s billion-dollar effort to improve the sanitary sewer system. The new line, costing $2.6 million, will increase capacity and should eliminate sanitary sewer overflows, according to County engineers.
