The septic was pumped yesterday. It didn't need it. The technician said we could have gone a couple more years and it looked healthy. But the water in the drainage field remained. Total cost: $250.
It seems that the problem was that our drainage field was half frozen, due to the time of year. So instead of a 50 foot field we had a 25 foot field that was unable to handle the extra people on the system over the weekend.
But the field may have failed eventually due to the roots around the field, so we now have to dig up the entire drainage area, till out the grass roots and add a few extra feet of soil over the surface to decrease the depth of freeze. It will take several hundred manhours to accomplish and lambing starts in two weeks.
The septic guy also recommended flushing pure nitrogen fertilizer into the drainage pipes to burn out any roots that have gotten into the system. Not exactly an organic solution is it? We'll have to plant a garden over the field to absorb the excess Nitrogen so that it doesn't drift into the aquifer.
And since we have had the tank pumped prematurely, we have about 2 weeks to complete all the work before the tank fills up with water, that has no place to go.
The good news is that there was no effluent in the drainage field. And the problem seems to be with the volume of water that went through the system last weekend.
So we are doing maintenance on the septic field that would have eventually needed to be done -- Maybe. But now we have a deadline which we didn't need at this time of year. Thankfully, we have 3 great WWOOFers here to help with the chore. God sees the end from the beginning and had things in place to help us, before we even asked Him for help.
