Experts lobby govts to adopt laws that promote rainwater harvesting

Even where water is available the cost of production and distribution limits the amount of water that will be supplied in relative demand, partly because utilities do not have enough money for production, thanks to high energy costs.

Also, where water is available, it has been found that utilities are competing with private farmers who want more water for irrigation.

A rainwater harvesting policy at its micro level of implementation should run alongside government schemes of harvesting rainwater at the community scale in places that experience extended rainy seasons and floods, so that these reservoirs can meet their demands for water during drought spells.

Experts reasoned that they should use the rain while it still falls, and at the same time employ strategies of reversing climate change because it is more difficult to stop volumes of water from water bodies and mountains from dwindling, than it is to harvest rainwater.

Besides water from sources other than rain usually requires a lot of energy to pump and clean it, making it expensive.
