Severn Trent Water Asset Creation was tasked with constructing a new sewage pumping station to replace an existing asset that had reached the end of its working life.
The scheme presented several core challenges
The template design solution proposed by the designers required a layout consisting of a 4.0m diameter wet well (complete with integral concrete valve chamber), online storage to provide a minimum of 2 hours of storage at dry weather flow (62.2m3).
NMCNomenca worked closely with Marshalls Civils and Drainage to further enhance the current design template for a precast solution, complete with an integrated valve chamber, for use on multiple schemes.
The solution adapted provided a combined storm storage, wet wall and valve chamber within a single structure at the present site location utilising 4.0m diameter precast shaft rings. The air valves, flow meter and Bauer coupling were located within two precast sections placed on top of the wet well shaft, with designed in watertight jointing.
The 7.0m deep caisson at 4.0m diameter provided increased storm storage with no requirement for an external tank.
The consolidated design solution utilised a reduced footprint and permitted the retention of the existing inlet manhole to be utilised as the temporary pumping station retained throughout the construction period.
By engaging the project solution and construction techniques the client, the customers and the local residents benefitted from
