A little background...
We inherited a slightly annoying water pumping situation when we bought this place. For drinking, washing, laundry and bathing we have two rain-water tanks situation for some reason about 30 metres from the house. We have a small pressure pump that draws from these tanks to the house. A second pressure pump sucks water up from the channel which we use for flushing toilets (I know, we plan to compost as we make renovations) and for feeding the evaporative air-cooler (I know! we are about to put up the northern and western pergolas and we will eventually put a shade house on the south). The water is really too dirty for the cooler anyway but that is what we inherited. This pump is what we currently use for irrigation purposes too.
Both pressure pumps and pressure tanks are under the house and make a good deal of noise when they kick in.
We have a third big tank on the shed which is full and not connected to anything so it just overflows at the moment. We also have a 'dam' that we can fill with our irrigation water 'rights'.
Our aim would be that we sort of future-proof ourselves if the SHTF in a serious way.
So here are my questions and the sorts of things I am contemplating.
1. We put in a new water tank close to the house on a tank stand (I have a used one lined up as a trade for dong some gardening work) to gravity feed us. Although there are issues with the solar hot water system with this option. We could then solar pump (or something?) up to the tank from the rainwater tanks.
2. Replacing the existing pump for the drinking quality water with a solar pump. Can you run a pressure pump on solar? Or is there an alternative?
3. Put in another tank (or using the smaller of the existing rainwater tanks) for settling the creek/tank water and just pumping it directly from the channel/creek with a solar pump. But then we still need some kind of pressure or gravity feed system for that.
I think there is more to consider but I have to go right now, perhaps you already have some suggestions or recommendations?
Cheers in Advance
