Generating Sets

Castleford Waste Water Treatment Works

United Kingdom

WARDPOWER were approached by Morgan Sindall Grontmij JV (MGJV) in 2013 to tender for the new Waste Water Treatment Works in Castleford, and in late 2014 we were successful in being awarded this project.

Being our first Generating Set to the Water Industry for a while, this was an important project for us but by no means an easy ‘win’. Every aspect of the Generating Set had to conform to not only WIMES but also Yorkshire Water’s (YW) own specifications – you can imagine the challenge that posed!

Now you may not think that an 80KVa Generating Set is anything to shout about, however, this bit of kit of was specifically sized to ensure all flood and storm pumps would be supported in an emergency scenario, whilst ensuring the overall size of the Generating Set was kept to a minimum. Let’s face it, no one wants a bigger Generating Set that they need, so why do it when we can marry an engine and alternator to suit the clients’ needs, rather than buying the nearest ‘off the shelf’ size? 

This Generating Set was designed, manufactured and tested at our works in Sheffield. The enclosure was again specifically designed to meet the requirements of WIMES and YW – 30 minute fire rated (in accordance with BS476), Table 1 (Environmental C2 (BS EN 12944) WIMES 4.01 external finish, achieving IP55 when running by the use of IP55 Eliminator and R17 filters on the air inlet attenuator and a noise level of 75dB(A) @ 1m.

The enclosure was also designed to have specific clearances, not only on the sides but also on the end and floor to ceiling. 

The floor, as you may well have noticed from above, is a fuel tank, sized to ensure the Generating Set runs for a minimum of 80 hours @ full load, with the base of the enclosure acting as the bund for secondary containment. The base tank was also designed and manufactured at our works in Sheffield and is as bespoke as everything else! 

Factory and site acceptance testing was undertaken in accordance with not only our own exacting standards but also complying with WIMES and YW Engineering Specifications. 

Project in Brief:

  • Sub‐Contractor under the CDM Regulations
  • Sizing and in accordance with WIMES and Yorkshire Water Engineering Specifications
  • 80KVA Prime Rated Containerised Generating Set
  • Installation Works
  • Commissioning
One size doesn’t fit all – this Generating Set, although modest in size, was specifically designed to meet the demands of this water treatment works
