Hi pkumar,
I've used robosand for plinth.I used river sand for sump.Concrete has come out well but I intend to use from a local supplier who claims to have way better quality for 28rs /cft. I'll see it's quality and Procure.
Thanks,

11000 ltrs sump construction
Re: 11000 ltrs sump construction
This is a type of pseudo RCC sump construction that has been adopted by builders and contractors to give the owner the feeling of RCC sump but it technically meets only the functionality of brickwall Sump though there is a RCC retaining wall. elaborated below.
Technically or engineering wise Brickwall sump , suffers high probable fractures mainly at the joint of 2 dissimilar materials , ie sump Base concrete slab and Brick Masonary wall. It can also suffer minute fractures and cracks on the side walls over years, and is worsened by low intensity tectonic activity, the plastering and waterproofing does not mitigate minute fractures and water seeping through it. Overall water seeps continuously (which is not felt by eyeballing the level of water, for ex few mm of water seepage amounts to 100s of liters) and weakens the foundation reducing the life of the building and valuable water is wasted.
To reduce chances of above, we go in for a RCC sump, In your case of pseudo RCC sump, The Brick wall and side RCC retaining wall forms a weak joint with the base slab, through which the seepage occurs minutely over years. but chances of side wall fracture is minimized with retaining wall.
True RCC Sump has to be 1 monolith cast with inside and outside walls being plastered with waterproof grade plaster. We did this for our sump of 15000 liters capacity few months back after reviewing all the possible ways of constructing a sump.

Hi Nivas,
I did not understand your dissimiliar Materials concept.
Actually speaking mine is fully RCC sump caged with cement brick wall. It's totally my idea and nothing to do with labour contractor as all are my materials. If you say that walls of rcc are dissimilar to cement blocks then your rcc sump is caged with soil that's entirely dissimilar. Kindly throw more light on it. I've seen brick sumps lasted more than 50 yrs until house demolition. I believe that proper Workmanship is necessary upon all the quality materials we use. In this same forum I've read that a single Brick was left at the base slab of a RCC sump which was as good as having a Brick sump. No offence meant just curious to know complex details.
Thanks,
Bharath
