To know more about wellpoint system, refer Dewatering Method – Wellpoint system for waterlogged sites. Page 10 - It is apparent from figure 4-11 that considerable computation is required to determine the height of the phreatic surface and resulting drawdown in the immediate vicinity of a gravity well (r/h less than 0.3). The drawdown in this zone usually is not of special interest in dewatering systems and seldom needs to be computed. Dewatering Proposals: Vacuum wellpoint system installed at nominal 1.5m centres Around the perimeter of the works to top of Clay using conventional water jetting installation method.
