Wet Well Material
(OP)
On a 130-180 gal wetwell for a sewage grinder pump, from what I have been able to gather (and this is not my field) it seems like Fiberglass Reinforced Polyester has been the material of choice. However, they also come in HDPE. What are their any benefits to choosing one material over the other?





RE: Wet Well Material
The criteria include cost, appearance, durability, leakage, corrosion resistance, owner's standards, and resistance to erosion among others. There are also different grades of FRP and HDPE that are available.
In general, either FRP or HDPE will provide satisfactory service in the application that you describe, a small prefabricated commercial or residential sewage lift station design.
The iink below decribes some of the issues when designing a larger lift station.

But if you're not in a roadway, a lot of these issues go away.
