Update: Water contact advisory continues for Beaver Dam Run and tributary
Update: The September 27 sanitary sewer overflows on Beaver Dam and Ashland Roads were caused by the failure of a temporary sewer pipe employed as part of Baltimore County's ongoing sewer inspection and maintenance program. An estimated 950,000 gallons was intermittently released at both the site of the break and at a manhole south of Ashland Road near Western Run.
Original press release issued on 9/28/16:
At approximately 9:30 a.m. Tuesday, September 27, County utility workers discovered a break in a temporary sewer pipeline just north of Padonia Road. Equipment and construction material were brought to the site and repairs began Tuesday to address the sanitary overflow, which was halted Wednesday morning at approximately 11 a.m. The volume of discharge as a result of the broken line has not yet been determined, but is expected to be significant.
Several intermittent sanitary sewer overflows, resulting from the single pipe failure, occurred at two sites: the site of the break itself on Beaver Dam Road, just north of Padonia and near a tributary to Beaver Dam Run, and a site south of Ashland Road between York Road and Western Run. The overflow near Ashland Road occurred as a necessary part of the process to repair the line at Beaver Dam Road.
The public is advised to avoid contact with the water. The Baltimore County Department of Health is monitoring water quality in Beaver Dam Run and the tributary and has issued a water contact advisory and will update the situation as needed on their website:
Further details on the cause of the overflow and the total volume of discharge will be published as they become available.
105,000 gallons released into stream near commercial area
Yesterday at approximately 2 p.m. Baltimore County Utility crews responded to a sanitary sewage overflow from a sewer manhole near Recycle Way and York Road, controlling the overflow at 3:30 p.m. Approximately 105,000 gallons were released into nearby Parke Run Tributary, a stream running near the commercial area and north of Recycle Way.
The sanitary sewer overflow occurred when utility crews were in the process of cleaning a sanitary sewer line. Crews installed a pump to stop the flow by 3:30 p.m. and then dislodged debris by 4 p.m.
The Baltimore County Department of Health has issued a water contact alert for the stream and will monitor water quality at the site and post further updates on the department’s website:
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.
