You may, or may not, know that we are so off grid that we only have the supply of municipal water. And, not the best water at that. But, it is drinkable, so mustn't complain... :) And that, together with our rain water tanks should stand us in good stead for our human requirements.
The ramifications though, are that our "waste water" is our responsibility. The black water goes into a large septic tank, and, providing that I feed the tank with "good bacteria" every month, all should be well.
But we didn't want our grey water (water from our shower, bathroom basin and kitchen sink) unnecessarily filling our septic tank.
So, we have installed plumbing to take the grey water to a "pond" ( in inverted comma's as it's a work in progress...:) )
The "pond" in the foreground - not such a pleasant view or experience |
Initially, with the chaos of builders, building, mess and confusion, the water just ran to the "pond". But the "pond" wasn't looking so good - in fact it was not pleasing at all. Distinctly unappealing even to the bird life. A direct result of all the inevitable kitchen grease and minute scraps of food which were being flushed down the drain. So I put on my thinking cap and came up with this solution...
The higher hole was inserted on the side of the kitchen sink pipe, and the lower hole is for the pipe to the pond |
Vermin proof lid on the grey water filter box |
Larger filter stones layer the base of the black box |
Smaller filter stones were laid on top of the larger stone |
A couple of layers of shade cloth to hold the sand |
A layer of clean sand |
Test run... |
HA!
I had another plan. We all know that washing machines like to chew just one of a pair of socks. And that one invariably has the odd-sock-out lingering in the hopes that it's mate will surface somewhere.
Leftover socks that the washing machine didn't fancy... |
Yup - they were put to good use as an additional filter |
It works a treat :) |
But, most importantly, the water that is heading for the pond is clean (er), and it doesn't smell anymore, and that result is worth a couple of minutes every 7 - 10 days in order to complete the unpleasant task of cleaning the sock...
Clean water - it works :) |
The plants are loving it :) |
