ABSTRACT
A deep well system consists of an array of bored wells pumped by submersible pumps. The wells act in concert: the interaction between the cone of drawdown created by each well results in groundwater lowering over a wide area. Because the technique does not operate on a suction principle, greater drawdowns can be achieved than with a single-stage wellpoint system. This chapter addresses the temporary works deep well groundwater lowering system and describes good practices to be used during installation and operation.
