A 72,600 sq. yard man-made lake, called Blue Heart, is being developed at By the Waters, a 100-acre residential estate about 35 km from Ahmedabad, Gujarat.
The lake uses a closed-loop system involving groundwater, rainwater harvesting, groundwater recharge and seasonal monsoon water capture.
Witteveen+Bos, a Dutch engineering firm, designed the lake’s hydrology, with automated water movement and sensor-based monitoring planned.
The project includes a 1.5-km lakeside promenade and 2-km kayak trail; native plants are planned to help absorb nutrients and support biodiversity.
The lake is near Thol Lake, a Ramsar-designated wetland, so ecological monitoring is being established to assess water, biodiversity and hydrological impacts.
