Getting the tank ready to go down.

Today, it was all about the water system, and probably tomorrow too. This is the tank that's going into the ground, I thought I would give one final cleaning. I think there is 2 leaves still in there that just did not want to come out. I'm afraid I might get stuck if I tried to crawl in there. It's pretty clean now, but was still showing a fair bit of sea weedy type algae or whatever in there when I started this morning.
I fixed the top of it a bit. It is not concave anymore, but who knows, when I start doing my thing in the cistern, it might end up being concave again. Hope not though. I had to build me a special tool to fix the tank. Just an 8 foot 2x4 with a 2 foot peice nailed on the end of it so I could put it in the tank and pry upwards.
Then I thought I better put some water in it and check for leaks. I only put in about 150 gallons, but it did'nt leak at the opening, even when I wriggle the valve around a bunch. The valve will be coming off, and the water line will be getting plumbed on here.
This was a pretty entertaining job, and alot of hard labor. The real soft and sloppy mud I thought should come out of the cistern. I started to pack it in pails. I would pack one up the ladder and then pull the other one up with a rope that I had tied to it. I'm pretty sure that I exceeded the weight limit of the ladder coming up. There was alot flexing going on anyway.
After packing about 8 pails of mud out of there, it was time for a different plan.
I hauled two hoe buckets of mud out. It still don't look the greatest thing for cleanliness down there, but I am now on more solid ground. Tomorrow, if the weather allows, I plan to put some tile rock down there and get it all nice and level. Then I'll put some pressured treated plywood on top the gravel for a nice flat surface. (Just happen to have a sheet and some scraps kicking around). A little plumbing, then down with the tank.

  1. Looks good. We also want to sink a rainwater tank (or two) but our problem (in clay) is that when the clay gets wet it expands, and that can affect / damage the sides of the tank...

    1. Hmmm. I've never thought of that before. Is that all clay, or do you have a different type clay in South Africa? Maybe it's just more rain and hot. I did'nt really have to put the tank in the ground. I Put it into a culvert cistern that I was originally going to pour concrete in. Thought I would just try this as an experiment and to save pouring the concrete.
