water treatment related question-about HDPE pipe
(OP)
I have got two questions
1.How do we connect HDPE(high density poly-ethylene)pipe to brick masonry inspection chambers having masonry thickness 8.5" or 210mm-the joint should be leak-proof
2.An ordinary connection with out flange-joints filled with cement mortar(1:2 ratio) and also concreted (1:1.5:3) was found to have leak.How to rectify this problem?.

RE: water treatment related question-about HDPE pipe
I have used a HDPE liner which is cast into the inside surface of the manhole. This enables you to weld the incoming pipe, to the liner, while still retaining the structural attributes of the manhole. A bit more costly but waste liquid manholes are things you do not want to have trouble with.
Another plan is to use a large diameter HDPE pipe as a manhole. In this way welding again becomes easy and the chemical integrity of the mahole is excellent
