Does anyone have a feel for how much superpave is going for? Never had to use it before. I have a wearing course of 1 1/2 inches and the base course of 11 1/2 inches of superpave each. Also anyone heard of cathodic protection on a water main pipe? Thanks for any information you may have.

Thanks David. This is what I came up after getting all the facts correct. The maintenance crew called in a twizzy. Renee

Well, the person who went out to investigate came back and I got a better story of the situation. We are on a very steep hillside. Above this neighborhood they shut off some valves to isolate a section of pipe to put in a check valve. Below this area another neighbor lost water. A few homes...

bimr. It's nice that I'm doing it right. I've taken of everything you mentioned. I have 8 ft between inlet and pump suction bell. My boss would like to see documentation that says this is o.k. I will check the resources you mentioned. I will also repost in on the pump forum as you suggested...

I'm designing a wet well (first time)and am seeking information on the distance from the inlet pipe to the wet well and suction pipe to the pump. To avoid influent vortexing from creating air pockets and thus caviation for the suction pipe, there should be a minimum distance between the two but...
