About a week or so ago I told you about our septic system problem (that here), i.e. that we discovered that we had no drainfield (leach field). Fortunately, the septic folks were able to get on it quickly.
They came with their heavy duty equipment one day, and within a couple of hours had dug a massive trench.
In constructing a leach field, the number, length, and depth of trenches are determined by several factors. These are spelled out in local building codes, but basically take in to consideration the type of soil, how quickly it absorbs water (known as soil percolation), and the depth of the water table. Because we had the land, ours is a huge long trench, starting at the septic tank near the back corner of the house and carport, and curving around to near the goat shed. If you take a look at field #1 on our master plan, you can probably visualize what I'm trying to describe.
The next day perforated drainage pipe was installed and embedded in 3/4" stone. Then the trench was filled back in and packed down.
It left a huge part of goat field bare. I reckon it's just as well I've only got two goats to start, because there's a whole lot less to browse on now.
Of course, bare soil never stays bare for long and it won't take long before we won't even remember what this looked like. It's really too bad we aren't ready to sow something here. Someday perhaps.
