Spectacular effort Herman!

PS: It looks to me like you didn't quite finish the "bottom" end of the painting?

Thanks @El Sid much appreciated. Yeah, every painting must have something not completed and you need to complete it in your mind or imagination.

The past week I really had minimal time to work on this project. The last bit of work on the sand filter tank was when I installed the new bulkheads.

Friday I had some spare hours in the afternoon so I motivated myself to dress up like a spaceman with a full dust protection suit, eye protection shield and full ventilator and sand down the white flowcoat all along the new bulkhead joints. Man, that was a bloody mission. Cramped space, hot and almost zero viz due to the dust. But in the end after 2,5 torturous hours, it was done.  After vacuuming for another 30 minutes I could see my handiwork.







Yesterday, I got up early and ripped two meranti planks to make the 45° bevel planks to go into the corners.

All ready to be installed.





Alas, yesterday was one of those days when something will go wrong if it has the slightest chance of seeing a gap to do so. It took me the whole day to install all the beveled corner pieces. I finished at 17h30 just in time to pack up, shower and drive to a mate of mine's house for a braai. I was wasted and it was an early night braai for us.

All done and ready for the fibreglass overlay.





This little section took a long time to do with all the mitres to work out and cut.





This morning, I woke up and looked at the weather forecast. The predicted rain has vaporised like my little savings pig ... so I had to grab the opportunity to do the fibreglass work. Something I did not look forward to as there is nothing worse than fibreglassing in a confined space. OK, maybe sanding in the same space ...

Fortunately the Boss took pity on my and helped me by tearing the matting to size and handing these down for me to stick to the first coat of resin painted onto the surfaces.

Five hours later and all done. Looking pretty neat even if I say so myself.






It was so hot today that I almost had to add no catalyst to the resin ... I was really chased in this section, but a smaller sized mix each time was the secret to success.





Tomorrow I will have buy some white poolcote and roll the tank out with it. Then onto making the ribs to support the polycarb ...

Early this morning I dragged the compressor out to the sand filter and sanded the inside surfaces of the tank. Once again looking like a spaceman ... after 1h I was drenched in sweat and decided to call it a day. I will clean tomorrow early while it is cool and then go to town and get the poolcoat.

Yes, you are the second person requesting info on the greywater system. I will need to get myself in order and write that up as there is basically only one correct and lasting way to handle greywater without you going grey in the process.

While the sand filter tank is drying (and blowing full of sand again) I finished the transformer.

This is what I started off with.





This is the final product ready to be mounted on the control panel's backboard.

The slow sand filter is finished on the inside. Now onto installing the ribs supporting the polycarb window, the pipework and then the sand in the filter.






The camera got confused with whiteout ... now imagine you are a bee or some other flying insect and the whiteout hits you...

The last of the pipes to go into the project arrived yesterday morning.

I made some time yesterday afternoon to do the draft layout of the two control panel boards. It will work great!

Now I need to save to buy three more pump controllers.  :help:

Very impressive Herman. But it does show what a serious undertaking a proper recycling system is, and beyond the means and/or abilities of the average schmo. A commercial system with these capabilities would cost tens of thousands if not far off R100k? Something to aspire to.

PS: did you hook the transformer out an old valve amp?  :ROFLMAO:

Yes @El Sid it is costing a bit. I need to go and do the sums, but materials cost so far is not far off R35k. However if you want something that works and requires almost no maintenance then you must design and build it to do so. Too many systems you can buy today to recover greywater and clean water is simply designed to make money out of the unknowing consumer. Sad but true.

The transformer is actually from an old HO train set my Dad had when I was one digit old. I found it in his garage when we cleared the cupboards...

Finally ... I have finished upgrading (and renovating the underground water tank). What was supposed to be a simple installation job to install a float level switch and a new inlet pipe to the underground tank, turned into a real project.

When I opened the concrete manhole cover, I found that one of the trees have managed to get its roots into the tank and that is a big no no  :nono:

So I had to clean the tank, allow it to dry, dress up like a spaceman with full face mask and ventilation and sand down the fibreglass joint where the two fibreglass rings that forms the tank were joined about 10 years ago. My son did the tank installation when he was still at school and he did a very good job for it to last for so long with no maintenance.

Man what a task it was to sand everything clean, and then apply new fibreglass matting and resin. To do this in a confined space can quickly lead to respiratory issues so I had to take all precautions.

After two weeks of working on the tank, I could finally close the lid today.

Here is a peek down the manhole with all the services installed on the left hand tank wall.





The repaired joint with three new layers of woven and stranded matting.






The submersible pump that has been going strong for ten years with no complaints.





The new float level switch on the right hand side of the picture with the new inlet from the other two tanks on the left hand side. So FLTR you can see, inlet from tanks 1 and 2, pump feed pipe to tank 1, rainwater pipe from the roof, 230VAC sleeve with cable to the pump, sleeve with cable from the float level switch that runs to the controller cabinet on the skid.

I had the following reply on the duplicate thread on 4x4community.

This is an amazing project.

Can you prevent the tree thing happening again?

Or is this something you will do each time there is maintenance?

My answer is as follows:
I cut the roots back and then coated the whole area with a very strong copper sulfate solution. This should prevent the roots from growing again in this area. With roots you never know where they will grow to!

Root clearance is basically a normal maintenance issue on any underground water related infrastructure. Just ask any plumber many sewerage lines are blocked by roots...

This morning no wind was blowing so I grabbed the chance to locate all the through hole fittings in the slow sand filter and drill the holes.

Why do you always need so many tools to do even the simplest of jobs?
