As part of United Utilities’ £3.5bn AMP6 investment programme across Manchester, the water company commissioned LiMA to deliver the multimillion-pound upgrade at Davyhulme. Davyhulme Wastewater Treatment Works is at the forefront of renewable energy generation and serves over one million people. The £200M modernisation includes the design, installation and commissioning of a biomethane plant that will convert waste to gas, which can then be exported into the National Grid. Aptus have a well-established partnership with United Utilities and were brought in to supply infrastructure at the plant.
Aptus Utilities were instructed by LiMA to construct the medium pressure import and intermediate pressure export pipelines to facilitate the injection of biomethane gas into the National Grid, and to provide a gas supply to the Davyhulme plant. This included the installation of telemetry system ducting.
In order to meet environmental standards, the treatment plant also had a requirement for a natural gas import pipeline to feed combined heat boilers and power engines, which would significantly reduce onsite consumption of oil and LPG usage and decrease the carbon footprint.
Through strategic organisation and preparation, Aptus Utilities were able to begin works ahead of schedule. With the successful interpretation of the environmental survey and planning in place, pipeline works were underway by December 2015. Aptus Utilities’ construction team worked proactively and efficiently alongside the client and sub-contractors, resulting in the installation, commission and adoption of 2.5km of mains before the end of March 2016, ahead of the client’s deadline.
The Aptus Utilities team at the Davyhulme Bio-methane Project achieved sign off from National Grid before the project deadline, with the plant meeting the high standards required to process bio-gas from sewage digestion into grid-quality gas for direct injection into the Grid. This enabled United Utilities to gain maximum green incentives for their product and, as the contractor overseeing the project, LiMA’s reputation within United Utilities was enhanced.
“Aptus Utilities have been recognised as key in delivering this project.”
“This is the first contract LiMA have let to Aptus, and all the project team have been impressed with the approach of your workforce and supervisors to the challenges presented.”
“The ‘can do’ attitude and diligent safety culture were prominent and your team’s focus on the overall objective took the risk away from this package. I look forward to discussing future work across the UU programme with you in the near future.”
