8.7 Water Pump

Nowadays, private households are increasingly making use
of rainwater alongside the mains domestic water supply.
This saves money and helps protect the environment.
Rainwater can be used for the following, for example:
Washing clothes
Watering the garden
Watering indoor plants
Washing the car
Flushing the toilet
The sketch below illustrates how such a rainwater supply
system works:

collecting tank
The rainwater is collected in a large water butt. From the
water butt it is pumped by a pumping station into a piping
system provided for it. From there it can be drawn off in the
same way as the normal household water supply. If the wa-
ter butt should run dry, it can be topped up with mains wa-
ter.
