The high per-capita consumption of drinking water, the dwindling resources, the increasing infrastructural development of agricultural land's support for rainwater, and the support of rainwater reservoirs by local governments have led to an increasing demand of rainwater.
Today, up to 50% of domestic consumption of drinking water can be replaced by rainwater.
The main part of the rainwater storage system is a suitable rainwater storage tank.
ROTEX variocistern indoor rainwater tanks have been developed with this in mind and correspond completely with the requirements of such systems.
