NG Bailey Case Study
Anglian Water serves 5.5 million people and 125,000 businesses in the East of England
Anglian Water
Theory
Anglian Water serves 5.5 million people and 125,000 businesses in the East of England, one of the driest regions in the country with a rapid rate of housing growth. The company’s goal is simple: To deliver a reliable supply of clean, safe drinking water and effective wastewater services at an affordable price. But achieving this in a region assessed by the Environment Agency as one of “serious water stress,” is a tough challenge.
With 42% of customers in flat, rural areas, it is little wonder that Anglian Water operates over 4,300 pumping stations, each one crucial to the water supply infrastructure. Every new housing development places additional load on the water main, reducing pressure and potentially compromising water quality.
Traditionally, to design and build a booster pumping station (known as a DG2) takes several weeks with multiple trades on site. Having heard about our Engineering For Manufacture capabilities via buildoffsite, Anglian Water came to NG Bailey for better way of solving the problem – how to deliver additional pumping capacity quickly and cost effectively.
Practice
The NG Bailey Offsite team immediately saw the potential to deliver an off-the-shelf product range for new pumping stations. The total cost saving of delivering this product, including design and engineering time, is over 20%, compared to previous projects.
The result is not only a value-engineered design, with all the cost-advantages of standardisation and industrialised production, but also a ‘configurator’ installed on the client’s intranet. This system enables project managers to configure the specific model they need, by pumping capacity (from 5 to 50 lt/sec) and 17 other options ranging from colour to whether they want a burglar alarm. The system turns out complete drawings, a bill of materials, delivery schedule and full assembly instructions, and the unit goes straight into production, which takes as little as three days.
We also refined the assembly process. A sacrificial template, set into the concrete base on site precisely determines the positions of all pipework coming into the plant room, so that when the unit is delivered it can be fixed and able to pump water in as little as 10 minutes. We expect to deliver at least 6 more DG2 units for Anglian Water, and hope to make the solution available under licence to other utility companies.
"The new product has reduced construction time by 50%, offering Anglian Water an extremely efficient solution and reducing disturbance to our customers. The use of innovative off-site construction techniques marks the product out as an excellent example to follow."
