Top tank overflow: design + implementation

On occasion, our two big water tanks at the very top of Milkwood Farm overflow. What to do with the intermittent extra water? It’s too precious to just drain away. Time to design a water catchment and planting plan to make the most of it.

Since solving this problem is both necessary and interesting, we decided to develop an intern project around it. The brief: design, implement and plant a system that makes use of intermittent excess water, shelters the intern camp and shed, and provides a useful yield. Go, you fabulous interns! Read More »

Re-setting the spillways

Our very full swale snaking past the house and into our very full dam

For the last 2 and a half years we have waited for the big rain which would test the capacity of our water-harvesting earthworks. And waited. We’ve had a bit of rain here and there, but the summers have been hot and dry these last two years, and we had gotten used to life with half-full dams and swales which were good roads, but rarely wet.

And then, when we least expected it, our system filled up. Finally. Read More »

Surveying the site from scratch

Having grand plans is all very fine, but there comes a time when one must make the first, single, decisive gesture towards action.

For us, this meant placing a small wooden peg, painted white, at the southern boundary of Milkwood. And then surveying a contour which continued aaaallllll the way around the hillside at the same height as that first peg, right around to the other boundary of Milkwood on the western side of the ridge. This first contour was important to mark out for a couple of reasons: Read More »

Milkwood – the water design

Standing on a bare hilltop, with the creek below and a small creekflat to the left, it all seemed so easy when we first got here… all we had to do was figure out where to put some structures, avoid the big trees, and build a bridge over the creek to get in. Grow something on the creekflat, put in a vegie garden, and get water from the sky… and the rest of it all, all those complex ideas and fiddly bits, could just wait till we were nicely set up.

Earthworks, water and other fantastic fun

Water is precious. And hard to find, around here. The process of designing hydrology into a site so that whatever water is available is used intelligently and for multiple purposes before it is allowed to seep out of the soil and into the creek is a tricky task. We have spend nigh on a year now, just watching the rainfall and the landscape and thinking and planning how we would best design Milkwood to make the most of our limited rainwater catchment.

How we could harvest that water and divert it across the landscape so that it seeps in gently and slowly, creating places for things to grow, rather than have the water pelting down the cleared gullies on either side of Milkwood, to swell the eroded creek and rush off downstream before the land and the soil has had a chance to benefit from it.
