Yes, the Rainwater collected through these drains can be used to recharge groundwater instead, and are keen to gather the opinion of citizens on this matter.Now now built construction has provision to collect rain water as well as drain water in a pit and recycled through treatment systemNo doubt, this water will carry along with it large quantity of solid waste, besides fine silt and will pose as a major hurdle in harvesting and hence will have to be handled with care. Rainwater structures that should be constructed should take into account this.The sub-surface reservoirs, located in suitable hydrogeological situations, are environment friendly and economically viable proposition. The sub-surface storages have advantages of being free from the adverse effects like inundation of large surface area, loss of cultivable land, displacement of local population, substantial evaporation losses and sensitivity to earthquakesIn particular, the features, parameters and data to be considered are: geological boundaries; hydraulic boundaries; inflow and outflow of waters; storage capacity; porosity; hydraulic conductivity; transmissivity; natural discharge of springs; water resources available for recharge; natural recharge; water balance; lithology; depth of the aquifer; and tectonic boundaries. The aquifers best suited for artificial recharge are those aquifers which absorb large quantities of water and do not release them too quickly.

An abandoned borewell presents a different geology - whether it is primary or secondary aquifer needs to be confirmed. The fact that it is abandoned is an indication it has touched rock bottom which is impervious. More importantly, the aquifer characteristics are vital in ascertaining the period of usage as well. Bore dia is important as storm drainage could be incompatible. Please verify these basic parameters prior to any decision in the matter. All the best.
