Title
Use Of Recharge Wells To Maintain Groundwater Levels During Excavation Of The Milwaukee Deep Tunnels
Author Ilsley, Roger C. ; Powers, J. Patrick ; Hunt, Steven W. 
Society / Organization SME 
Summary / Abstract Artificial groundwater recharge has been used successfully to mitigate water level drawdown in upper alluvial deposits during construction of the Milwaukee deep rock tunnels. Recharge wells in rock as well as soil were used. The effort reduced settlements from consolidation of compressible estuarine deposits, and has minimized damage to existing structures. The paper describes the geology that presented the consolidation problem, and the hydrogeologic conditions that caused the drawdowns. Also presented are the details of recharge well design, construction, operation and performance in an urban environment. The project design calls for grouting and lining of the tunnels to control groundwater in the long term.
