There are currently 111 Internal Drainage Boards (IDB) in England covering almost 10% of its total land area, as well as a further 14 in Wales, now managed by Natural Resource Wales (NRW). Playing a key role in water level management and flood risk control, IDB’s operate and maintain over 500 pumping stations, 22,000 km of watercourse, 175 automatic weed screen cleaners and numerous sluices and weirs. IDB’s are involved with water abstraction and screening operations throughout England and Wales. The GoFlo self-cleaning screen can offer significant regulatory, technical, operational and financial advantages.
You will be aware that screening at many water abstraction (intake) and outfall points must comply with increasingly stringent fish and eel screening regulations. The Eels (England and Wales) Regulations 2009 for the recovery of the European eel, has led to the creation of UK-wide Eel Management Plans and will be enforced by the Environment Agency and other relevant bodies across the UK.
Water intake screens are owned and operated by a large range of users within the UK, including hydropower operators, Internal Drainage Board, public and private water treatment and supply companies, agricultural users, the industrial sector and by any other user that involves some impoundment, abstraction, discharge or obstruction of water in an area of coast, estuary, river or inland body of water that is of importance to the passage of eels. Check here to find out more about the new regulations and what it means for water abstractors.
GoFlo is a rotating, self-cleaning travelling water screen that offers water abstractors an innovative and compliance-friendly solution to eel screening, as well mitigating the other key problem with conventional intake screens, that of debris accumulation, reduced flow and high maintenance requirements.
GoFlo travelling water screens offer far reaching operational benefits. The screens feature a fully automated rotating screen and debris removal feature, requiring minimal manual input. Mesh sizes can range from 50mm down to 2mm in order to meet the most stringent eel screening requirements. Screen cleaning cycles can be activated by sensors detecting differential water levels across the screen, or programmed at fixed time intervals, or manually activated either onsite or remotely. The GoFlo control system is a full PLC-based system with internet connection for remote access and includes a webcam for watching the screen anywhere in the world. Combined with an extremely low maintenance design, the control system acts to maximise flow at all times.
The technical design features of the GoFlo travelling water screen include a robust, corrosion free stainless steel construction, self-lubricating bearings, a pivoting base for quick installation and removal, automated debris removal with a spray and flushing system and a fully modular design for multi-screen requirements of varying sizes.
