The Matrimandir Lake is rooted in Auroville’s regional commitment to developing an area-wide innovative water management system. In the monsoonal months of rainfall in Tamil Nadu, 90% annual precipitation occurs in just two months and water storage is a crucial challenge. The geomembrane’s installation is a critical process, immediately following the fine grading of the slopes to prevent damage from rain. The lake’s shores will store one billion liters of rainwater over ten months and are carefully designed with a 1:3 slope, reinforced with large concrete blocks. The slopes are meticulously smoothed and compacted before the HDPE waterproofing layer is installed, to ensure zero water loss.
