Ocean City Wastewater Treatment Plant Biosolids Treatment Improvements. Ocean City, Maryland.

WRA provided planning, design and construction administration services for improvements to the solids handling facilities at the Town's 14 million gallons per day (MGD) capacity wastewater treatment plant.

WRA conducted a one-year study for the Town of Ocean City, Maryland to evaluate the feasibility and provide recommendations for the addition of a sludge pasteurization process. The Town was faced with difficulties in disposing of the currently produced Class B sludge and was in need of flexibility and reliability for future disposal. WRA conducted evaluations of three sludge pasteurization processes, facilitating Class A sludge production. The Envessel Pasteurization™ process was recommended and WRA prepared designs and provided construction administration services for the new Class A Biosolids Treatment Facility. The new facility eliminated the previous operating problems and produces a beneficial Class A biosolids product, while significantly reducing operating costs.

Project Highlights

Water/Wastewater Facilities

WRA provided engineering services during construction and on-site resident project representation for the entire construction duration.

Biosolids and Residuals Handling

WRA prepared process mechanical designs to integrate the selected Envessel Pasteurization™ process equipment into the design. Other designs included rotary press dewatering equipment, thickened sludge holding tanks, and sludge pumping and conveyance systems.

Architecture

A new building was designed to house all new process equipment. The building featured a truck bay drive through to facilitate loading of the Class A Biosolids.

Structural

The project included design of the concrete structure for the Biosolids Building, including augered pile supported foundations. Structural design included steel, concrete masonry, and cast-in-place concrete.

Civil/Land Development

WRA designed all new underground utilities including utility relocations. A separate site preparation contract was prepared to facilitate the completion of the project.

Geotechnical

A subsurface investigation was performed to determine on-site soil conditions and to provide foundation recommendations.
