KENTFORD TRANSFER PUMPS, BEXWELL - WATER
PROJECT DETAILS
Project Name: Kentford Transfer Pumps (Bexwell Pump Station) – Strategic Pipeline for Anglian Water
Project Type: Transfer Pumps on a potable water application.
Pumps/pump Package Used: 4 off frame mounted BS08EL fitted with 250kW LV motors with pump casings in stainless steel
Location: Bexwell near Downham Market, Norfolk.
BACKGROUND
What is the Strategic Pipeline alliance (SPA).
AWS looks to future proofing our water supplies by creating hundreds of kilometres of new interconnecting pipes to help AWS move water more freely around the region.
It’s one of the largest infrastructure projects in the UK and will help future proof water supplies for future generations. AWS will be able to divert water from the wettest areas in the north of our region to the driest areas in the south and east, where water isn’t as easily sourced. This will reduce the amount of water taken from the environment, as well as strengthening local resilience by reducing the number of homes and businesses which rely on a single water source. The Strategic Pipeline Alliance (SPA) total investment will be about £400 million and, once complete, the new network will be longer than any UK motorway. It is a significant part of our planned investment in the region over the next five years. The success of SPA is fundamental to supplying free flowing water throughout the region, making us more resilient to risks of drought. The programme also enables sustainable economic housing development for a rapid growing population. The scale of the work and pace AWS need to deliver it can’t be underestimated. But their core commitment is to look after the environment as they go, creating an environmentally sustainable water supply which will protect the areas streams and rivers and the diverse wildlife that depends on them.

OBJECTIVE
The Strategic Pipeline Alliance (SPA) is creating hundreds of kilometres of new, interconnecting pipelines to help combat the impact of climate change and keep fresh, clean water flowing across the Anglian Water region. Anglian Water aims to make the region, one of the most rapidly growing in the country, resilient to the risks of drought by securing water supplies for future generations.
SOLUTION
This scheme had several challenges to overcome which included ensuring the motor was located above the station predicted “flood level”, being able to operate over a wide range of flow and head requirements & ensuring the pump was fully compliant with the drinking water requirements of drinking water inspectorate and Anglian Water.
Flood level – to overcome this the motors were mounted on a frame & the connection from the motor to the pump was via a suitably size driveshaft & coupling unit.
Flow and head requirements – the clients design criteria were based on the most efficient pump on the market which could cope with wide range of flow and head requirements, but not at the detriment to overhaul life expectancy of the pumpsets. The SPP solution came out on top when compared with other pump manufacturers.
Drinking water compliance – to ensure full compliance SPP offered their LLC range of split case pumps with an enhanced casing material of 316 stainless steel whilst maintaining a competitive capital cost.
