Protection & Lining of Rain Water Harvest Reservoir with Geosynthetic Products at Gummudipoondi, Tamil Nadu

Suryadev Alloys and Power Pvt. Ltd. planned to develop and harvest the rain water by creating a raw water reservoir at Gummudipoondi, Tamilnadu. The project aimed to prevent water loss due to seepage and to protect the slopes of the reservoir. To achieve this objective, a impermeable lining system with protective layers to the impermeable layer was designed and implemented on the entire surface area of the reservoir. The protection layer to the HDPE geomembrane impermeable lining system was sandwiched layers of non-woven geotextile layer, followed by a cement mortar layer, and a geocell layer filled with concrete. The anchoring mechanism for the lining system was also designed, which included an anchor trench and J-Hook made of MS bars. The lining system provided effective protection against seepage and ensured the durability of the reservoir.
