Work has recently been completed on the largest, fully commercial gas-to- grid plant to be built in the UK to date. Situated at Minworth Sewage Treatment Works, this new facility will purify sewage gas on behalf of Severn Trent Water. When operational, it will process up to 1500m3 of renewable biogas per hour to a state at which it can be safely injected into the national gas grid, making Severn Trent Water self-sufficient in gas. It expects to be able to supply 4,200 homes annually from this plant alone.

Whitehouse were appointed to undertake all the civils elements of the scheme, working in tandem with the mechanical and electrical teams to ensure the key delivery dates were achieved.

Due to the cutting edge specification of this gas-to-grid scheme, all works involved were of an intricate and complex nature with exacting tolerances which Whitehouse were able to achieve mitigating overall risk of the scheme.

Our skilled project delivery team ensured key areas of risk, including working around the existing sewage treatment works operations, were managed safely and efficiently whilst managing a number of trades closely.

Works on this scheme involved the construction of hard-standings, including extensive drainage works, all whilst working in close proximity to high risk gas pipes.

We installed fencing around the site and undertook all road markings and signage, alongside the excavation and landscaping of the surrounding area.

Works were completed on time and within budget to the complete satisfaction of the client.
