We have 4 rainwater tanks for the main house (Linstock), the main
house garden & the main house outside laundry. The same 5000 gallon tank
that feeds the outside laundry also feeds Elm Cottage via a 12 volt pump under
the cottage. Both houses are solar powered.
The lower cement
5000 gallon water tank is fed from the roof of the main house via down pipes
from both the front & the rear of the house. The water from this lower tank
is then pumped up to the higher tank which gravity feeds the main house.
This pump is
also a fire pump, it draws water from the stop cock on the side of the lower
tank & pumps it up to the higher tank via a pipe that runs underground.
This image shows
the two "first flush" pipes on the lower tank. Any dirt on the roof
or in the gutters is washed into these two pipes. When full, a ball float in
the pipe rises to the top closing off these tow pipes & allows the rest of
the water to flow into the tank. Over time, the water in these pipes is
supposed to slowly run out via the hoses at the bottom, but invariably the
small hole blocks with dirt, so every now & then I remove the bottom of the
pipes, drain & wash out the filters.
The garden tank
was placed on higher ground to the level of the garden so it would gravity feed
better, but this meant that it was too far away from the house to use an
overhead down pipe to fill it from the roof at the end of the house. So I run
the down pipe underground then back up into the top of the tank.
This is the new
5000 gallon poly tank that feeds the outside laundry, & Elm Cottage. This
tank is fed from the roof of Elm Cottage, but the ground close to the cottage
was too soft to provide a firm base for the tank, so we placed it on higher
ground. Again this meant that the tank was too far away to use overhead down
pipes, so again the pipe to the tank from the cottage roof was placed
underground then back up & into the top of the tank. The other pipe you can
see is an overflow pipe which I have run into a water butt.
Cattail Pond is actually a dam we had put in to collect & store more water from the header stream in Butterfly Valley. It also enables us to keep fish for food. Cattail Pond feeds the gardens at both houses via another fire pump at the side of the dam.
