Most systems are designed for a particular site and so there is standard information we request to enable us to determine the most suitable system for a project. It is not necessary to provide everything listed below, but the more details you can supply on what is required the more accurate we can be on what type and size of system may be needed.
If you would like to discuss a project please contact us with as much information as possible.
What is the system required for? Is it needed to deflect a particular species of fish or to comply with legislative requirements, such as eel screening, or the 316b rule? Or are there operational issues or other regulatory requirements?
Is the water abstraction for a power station, hydro-electric, industrial, drinking water, flood defence, or irrigation facility? Or is there another possible use, such as herding or guiding the fish?
Operational Requirements What operational requirements are there on the system? (Will it be operating 24 hours a day, 365 days a year, or is it required to operation only through a migration period, or during certain site conditions?
Where is the site? Please supply plans of the site layout.
Is there an intake, pumping chambers or other existing or planned structure?
Please provide engineering drawings of the intake/site.
What are the key fish species that need to be deflected, and their size?
What is the maximum water velocity into the intake?
What are the maximum / minimum water temperatures when the system will be operating?
Is there a fish by pass installed? If so, what flow is entering it, in comparison to the intake, and main ‘river’?
Is any bathymetric data available for the area in front of the intake?
What are the maximum and minimum water depths at the intake (most importantly what are the design water levels when the system will be required to operate?)
Please provide information on the maximum, minimum and mean water turbidity at the site.
Is there anywhere available to house the Control Equipment? And what is the potential distance to the intake?
What are the maximum / minimum air temperatures when the system will be operating?
When is the system required?
