All wastewater (grey water) is treated, through a process of filtration, aeration and ionization to be reused for gardens in a way that such water eventually percolates into the open wells and so completing the loop of use and generation. This treated water is also used in the toilets.

Kitchen wastes are segregated into organic /inorganic wastes. Organic waste goes to the vermicomposting pits where they are converted into Vermicompost, a nutrient-rich natural fertilizer and soil conditioner to be used for the garden.

3.6 Energy management through innovative interventions

Intelligent lighting systems blend motion sensors, ambient light sensors and timers to ensure that lights are switched off when not needed. Compact Fluorescent Lamp (CFL) and Light Emitting Diode (LED) based bulbs serve as highly efficient illuminating systems reducing CO2 emissions (1 CFL saves 0.1 tonnes of CO2 per year) and reduces power consumption by up to 80 per cent while protecting lighting efficiency. Nano-technology based solar lighting system (like quantum dots) for dwelling houses is expected to be close to 100% efficiency, energy and economy too.
