Murphy has won a £57m contract to construct a new facility in West Yorkshire that will convert human waste into electricity.
The contractor has been chosen by Yorkshire Water for treatment works in Brighouse near Huddersfield, which will process human waste to make electricity.
When completed, the new plant will receive sludge and waste water, which will then be processed over a 15-day period. Over that time anaerobic digestion occurs, a process in which the bacteria feeding on the waste produces biogas.
The biogas produced is then stored in huge containers, which can then be sold to companies to burn for electricity. The gas is also used by the facility to heat up the human waste for the process.
To carry out this process the plant will require the construction of anaerobic digesters; a new sludge reception plant; sludge thickening plant; CHP and dual fuel boilers.
Work started on the plant this month and is set to be completed 2021.
The work will see Brighouse’s existing sewage sludge incinerator demolished and replaced.
Murphy water sector director Stuart Rothery said: “This is a great example of our strategy in action.
“Building on our strengths and in particular, the process engineering expertise we acquired in 2017, we’re now in a position to really generate value for our UK clients by offering an integrated in-house service for complex water and wastewater design and construction.”
It is the latest major utilities deal won by Murphy this year. Last month the contractor won a £35m National Grid contract to replace high voltage cabling in south London.
The company also landed a £42m contract to build a new 6 km sewer north of Bristol in April.
Murphy acquired Carillion’s UK power business in February following the collapse of the contractor.
In its results for the year up until December 2017 the company posted pre-tax profit of £12.4m, down from £23.3m for the previous 12 months.
