> Rainwater collection is more nuanced than this article suggests. Water that runs off a roof of a building isn't "wasted." It typically drains into an aquifer or a river. Doesn't the article address this nuance? "It doesn’t rain often here, but when it does it can rain very hard. And the ground doesn’t soak up water very well. So rainwater harvesting is a way to deal with stormwater runoff." Some kinds of soil are limited in their ability to absorb water (in terms of rate). I believe these are soils with lots of clay in them. So having rainwater collection systems, though it would hurt groundwater recharge, probably on balance is better since it relieves demand on pumping out more groundwater.
