ABSTRACT
Water scarcity issue is dominatingly seen in the big cities and continuously increasing in the past years. The proposed system investigates that the standalone solar PV, which is used for the household electric load, can also be used for the grey water recycling with the optimised system design. The paperwork not only saves the recycled grey water but also fulfil the residential electric load. The proposed system further compared with the conventional system. The result obtained shows that the system saves 14,721.5 gallons’ water per year; also the cost of the proposed system is less as compared to the conventional system.
Disclosure Statement
No potential conflict of interest was reported by the authors.
Future scope
The paper proposed a novel idea for utilising rooftop solar PV for grey water recycling. The work can further be extended to the places far from the grid reach and facing the water scarcity issues, also for the microgrid including the residential commercial load can be explored for the proposed work for water recycling.
