Ashburton Tanks Project

Ashburton Tanks Project

Baltimore, MD

The Baltimore City Department of Public Works (DPW) is converting open-air drinking water lakes to buried tanks to help preserve the city’s drinking water system and comply with federal Safe Drinking Water Act regulations. Stiver Engineering provided a custom shoring pit with support frame, plans for pipe supports and pipe hangers for large diameter steel pipe. We also provided the review of pipe plugs and the design of thrust restraint steel frames for large diameter pipe plug testing. Stiver Engineering performed bi-monthly slope stability reviews for the tank executions which were 430 ft. diameter and 50 ft. deep. We also provided excavation plans in rock material at critical locations for the installation of the influent pipes and the tank foundations. We reviewed rock borings and provided a trench safety plan. DPW is investing in safer and more secure drinking water with underground tanks.
