OK Nath - here's the overall plan of the property. Google Earth/Maps was so grainy I thought this would be a better option. There is about a half metre fall from left to right.
We had a landscape architect draw plans back in May 1994 not long after we moved in. It was Winter and I wanted ideas for when Spring came along. Since then the changes have been adding tanks on the left, a pool in the back right and my boat in the front right hand side.
Main tanks have a Grunfos pump which still works well. I'll need to do a flow test - but I'm thinking that the areas I'm watering are quite small so I'm fairly confident it won't be an issue. The secondary tanks have a "cheap & cheerful" pump that has been loyal for over 10 years. This is in line to the tanks also with green-stripe. Both systems have independent power and able to fill in either direction.
To date I've been happy to use timer taps and hoses to oscillator sprinklers but it's time to step it up a level.
My overall idea would be to end up with an automatic system for watering the lawns. With the gardens mature, they are topped up so infrequently that running a timer tap is so easy. Running pipe and wiring around the boundaries will be easy.
