The county’s sewage plant is set for repairs after the Arlington County Board approved a five-year contract at its meeting on Saturday.

The Water Pollution Control Plant’s concrete tanks at 3402 S. Glebe Road, near the Aurora Highlands and Arlington Ridge neighborhoods, are struggling with structural deterioration. They will be repaired with grouting, coating, crack injection, or by other means by an on-call contractor during the five-year contract.

The plant has 60 concrete sewage channels and tanks that help treat the county’s wastewater, and — despite recent upgrades — some of the tanks are over 65 years old.

The contract has a set cost of $1.25 million, with an additional $125,000 set aside as a contingency. In recommending the plan, county staff said scheduling repairs ahead of time rather than doing them on an emergency basis will reduce costs and risk to construction workers.

The County Board approved the contract as part of its consent agenda at its meeting Saturday (July 15).
