In our office work location comprising of about 300 employees, upon rough calculations, nearly 400 Liters of unused drinking water without any contamination is being drained to sewage.
Reasons are:
1) replacement of leftover water in the waterbottles every day
2) Partial consumption of water from fully filled glasses of water by employees and the remaining half is being drained by canteen personnel etc.
I would like to prepare a proposal for redirecting the water to a recharge pit so that the drinking water from above sources can used for ground water recharging. Expert advice in this regard is highly solicited. Do advise me on the feasibility, practical aspects and if any precedence exists for such a plan.
