A shoring system for controlling liquid on a site comprising a plurality of slide rails and a plurality of lateral plates. The plurality of slide rails comprise at least one liquid-controlling slide rail comprising a hollow body and lateral openings permeable to liquid when the at least one liquid-controlling slide rail is positioned into the ground. The openings are positioned on at least a portion of the liquid-controlling slide rail directed outside of the excavation. Each of the plurality of slide rails comprises at least two plate rails. Each of the plurality of lateral plates can be slid into the plate rails of two adjacent slide rails of the plurality of slide rails.
