The application of precast structures to municipal
waste water treatment plant construction can significantly expedite
the project and save considerable cost for both the contractor
and the owner. PEM, with its specialty casting and heavy-lifting
capabilities, has built many structures for treatment plant applications
with important savings to the municipality.
Lift stations also represent
an ideal application of precast structures. A wide range of vessel
retention volumes and mechanical hook-ups can be accommodated. For
special applications, structures can be built with T-lok liners,
and a variety of rubber or stainless steel pipe connectors.
Structures are typically
built as a monolithic base and wall section, with separate precast
top. Where depth exceeds transportation limitations, or where weight
exceeds field lifting capabilities, structures may be built with
separate riser sections with sealed joints.
