The Bel Air Board of Town Commissioners unanimously approved several contracts for town sewer system mapping and repair projects Monday.

The contracts will be funded with a total of $551,700 in "tax-exempt financing." Before voting on the individual projects, the commissioners unanimously approved Resolution 1000-13, an obligation bond to provide money for the projects.

The funding is in the town's budget for the 2013 fiscal year, which ends June 30.

The first contract, with Maryland Environmental Service, is for $251,700. The quasi-state agency will be hired to assist the town with developing a capital improvement plan for its sewer system.

Public Works Director Randy Robertson said the town's previous capital improvement plan for its sewer system was developed in 1994.

Robertson said Maryland Environmental Service staff will assist town staff with putting together a "comprehensive GIS [Geographic Information System] database" for the system, as well as a number of other services.

The commissioners then reviewed and unanimously approved two contracts for individual sewer rehabilitation projects.

The first is for sanitary sewer rehab in the Homestead and Shamrock communities. The $247,345 contract was awarded to TRB Specialty Rehabilitation, of Gambrills.

The firm will be hired to repair sewer mains, perform manhole inspections, plus clean and perform video inspections of 20,608 linear feet of sewer lines.

"These repairs will help rehabilitate the aging sewer system in Homestead, and identify what work needs to be performed in Shamrock to rehabilitate, and reduce the amount of groundwater entering the system," Robertson told the commissioners.

The second contract was with Insituform Technologies LLC, of Baltimore, for $52,651, to conduct "manhole-to-manhole" rehabilitation in Homestead.

The manholes are along 1,421 linear feet of sewer line.

ABC chair recognized

Mayor Edward Hopkins honored a local woman for her 30 years of working to beautify the town.

"Everyone agrees wholeheartedly that Bel Air is the way it is because of Dot's attention to detail, and the flowers," Hopkins said as he presented a proclamation to Dorothy "Dot" Maurer.

Maurer is stepping down as chair of the town's Appearance and Beautification Committee, after having served on it since 1983.

Generator contract approved

The commissioners unanimously approved a $112,800 contract with Monocacy Valley Electric, of Littlestown, Pa., to install two diesel emergency backup generators at the Bel Air Armory.

Robertson said the generators are necessary because the Armory is designated as a "secondary operations center" for the town administration and Police Department if an "emergency event renders the town hall and Police Department building unusable."

He said two generators are needed because the Armory has single-phase and three-phase power circuits; one will be powered by a single-phase 125 kilowatt generator, the other by a 150 kilowatt three-phase unit.

Robertson said it will take six to eight weeks for the contractor to have the units manufactured, and then several days to install them in mid-summer or early fall.
