At Embassy Galaxy (Towers A, B, C), the reject water from the RO system was earlier being discharged into the stormwater drain instead of being reused. Recognizing the opportunity to reduce water wastage, improve water management efficiency, and promote environmental conservation, it was decided to divert RO wastewater for non-potable use.
Objective
The objective was to redirect RO wastewater from the stormwater drain to the overhead flushing tank, ensuring 100% utilization for toilet flushing purposes. This initiative also aimed to conserve potable water and minimize water wastage.
Steps Taken
Two key steps were taken to achieve this objective. The pipeline and spares used were salvaged from waste materials, requiring no financial outlay.
- Step 1: Pipeline laid to connect the RO discharge point to the flushing tank of the respective tower.
- Step 2: Water meter installed in the new line for regular monitoring of water usage.
Outcome
This initiative has resulted in water savings of 790 kL per year and cost savings of approximately Rs 246.63 per day.
