Is CCFRP pipe suitable for storm drains?

Is CCFRP pipe suitable for storm drains?

Is CCFRP pipe suitable for storm drains?

(OP)
I am looking at the possibility of using a short section of Centrifugally Cast Fiberglass Reinforced Polymer Mortar (CCFRP) pipe, direct jacked through an intersection.  

This is part of a storm drain trunk line and will be passing stormwater which is mostly runoff from city streets. The area is only partially developed now, but I expect it will build out quickly (within about 10 years).  The amount of sediment and sand in the storm drain should be minimal.  Is this an appropriate usage for this type of pipe?

RE: Is CCFRP pipe suitable for storm drains?

Well, I did a search of this pipe, and could only find one reference to it, applied to natural gas.  I've never seen it used for water, much less for a jacking application.  If I may make a suggestion, why not look into proven materials and construction methods, for example, tunnel liner, jacked concrete pipe, directional drilling with HDPE pipe (caution re: inverts).

RE: Is CCFRP pipe suitable for storm drains?

Are you talking about "Hobas" pipe? or the one that is manufactured in Europe and or Wisconsin? Hobas is a good jacking pipe. I've used it and put 800 tons of force on it. Just make sure you do a good estimate of the jacking forces you need. they can make the piope as strong as you need it to be.

RE: Is CCFRP pipe suitable for storm drains?

LeoSC, your note re. directional drilling is correct. I doubt that this technique is suitable.

I am talking about HOBAS pipe and it is used for both water and sewer and is an excellent material for jacking.  My question is more in reference to it's durability, especially against abrasion.  The manufacture assures me it is very good, but I would like more objective opinions.

RE: Is CCFRP pipe suitable for storm drains?

It is more resistant to abrasion than straight RCP.
