To replace an existing intake which suffered from severe blocking problems.
- Increase generation of scheme by improving intake screening performance.
- Reduce operational costs related to screen cleaning and supervision.
The Doorian scheme was built in 2001 but the intake structure utilised a side-intake, upstream of a small weir. Located on boggy peat moorland, the intake blocked very quickly with grass on a regular basis, leading to significant lost generation. Having provided operation and maintenance services at the site since 2007, Dulas were contracted by Celtic Hydro to design a new intake structure to enable the installation of Coanda screens and increase plant generation.
Dulas delivered a turnkey project including all consents, landowner negotiation, construction, project management and optimisation. The project was completed on time and within budget.
