Sudlersville Wastewater Treatment Plant ENR Improvement Project

Queen Anne's County, Maryland is requesting sealed bids for construction of a Post Anoxic Reactor (PAR) tank and associated improvements at the Sudlersville Wastewater Treatment Plant (575 Thunder Road) under Contract No. SAN 26-01, with bids due September 22, 2026.

The scope encompasses rehabilitation of the existing Biolac reactor via removal of accumulated sludge and full replacement of air diffusers, replacement and enhancement of the chemical feed delivery system, cast-in-place concrete PAR tank construction, and installation of associated electrical and system control facilities. The work is essential to improve the plant's Elemental Nitrogen Removal (ENR) capabilities to meet regulatory environmental standards. Bidders must demonstrate experience with similar wastewater treatment facility construction projects, concrete work, electrical systems installation, and HVAC/mechanical systems.

Place of performance is 575 Thunder Road in northern Queen Anne's County. The contractor must coordinate with County engineering and operations staff, maintain safety protocols during active plant operations, and comply with environmental regulations throughout construction. Insurance, bonding, and prevailing wage requirements apply. Work will be performed in phases to minimize disruption to the treatment plant's operational capacity. The project is funded through the County's wastewater treatment infrastructure budget and likely involves state or federal environmental compliance grants.
