Not necessitating discarding rainwater by usage of drains also ensures that significantly less electric power is required (extra pumping is or else essential from the h2o-distribution method), and no rainwater gets polluted since it now not mixes with polluted drinking water. Rather, it is instantly absorbed by the bottom.[citation necessary]
