uPVC Pipe and Precast Manholes for Sewerage Works?

I am interested to know is anyone is aware of manufacturers of uPVC pipes as per IS 15328- uPVC pipes for underground drainage and sewerage works. Enquiry wilth a number of vendors were futile. Instead, uPVC as per IS 4985 has to be used for external sewerage work.

Also, I am eager to know whether there had been any sewerage work carried out in India with precast concrete manholes?

If people agree we can request BIS to frame something in line with ASTM C478 or BS 5911, globally well accepted standards for precast concrete manhole.

Dear Dr Rao

Thanks for your reply.
MAy be my question regarding precast concrete manhole is not clear. What I tried to mean is manhole built up of precast concrete rings/units. This is not precast manhole frame and cover. I am very much aware of precast manhole frame and cover as per IS 12592. That is very common.

Possibly in recent times some ADB project in Karnataka has used precast manholes. But this is not very common. My objective was to know the experiences of using such manhole. Because I feel quality control is a big problem, as these precast units are not available as readily manufactured units like like manhole frame and cover.

Hope the question is clear now.

There was not much helpful answers to my question. However, I could get some solutions. Just like to share if anyone is interested.

IS 15328 grade pipes are manufactured by some companies. One big manufacturer is Supreme. Their website is http://www.supreme.co.in. other manufacturers are there like Jain Pipes.

These pipes are manufactured for both solvent-cement jointed and elastomeric joint.

We do not have any Indian Standard for Precast Concrete Manhole (Please do not confuse it with pre-cast manhole frame and cover). But this type of manholes are recently used in large scale in Karnataka ADB project (KUIDFC) in Mangalore.

May be it will be useful for someone.

We are using Precast Manholes in two UGD projects in Karwar and Mangalore. It is very good system for work in sandy and silty earth conditions and higher depths with high water table.

5. Dear Hemant, please get in touch with us, need details

7. Precast manholes - procedures for laying is very convenient

I have been working in Mauritius for sewer reticulation projects where the manholes used are of precast make. The total manhole is casted in three stages .The base middle rings and slab, number and size of middle rings will vary according to the depth and dimensions of the proposed manhole.

The procedures for laying is very convenient, fast and effective. Quality control is not a problem unlike brick manholes used in India. Its is easy to get relative tests.

I am also willing to relocate in India for sewer reticulation. Can contact me for any prosperous opportunity.
