SPA systems are primarily used to deflect fish from entering water intakes or water channels, but can also be used for other applications, including deflecting fish from within pumping chambers and herding fish from areas as part of fisheries management protection or exclusion measures.
Typical installations include power stations, industrial facilities, drinking water, irrigation and pumping station intakes.
A SPA system is analogous to a public address or domestic hi-fi system, using underwater Sound Projectors (or loudspeakers), connected to Control Equipment by cables, to create a repellent acoustic field in front of a water intake. FGS can supply different models of SPA system to suit different site conditions.
Where additional deterrent is required the Sound Projectors are coupled with FGS’s High Intensity Lights to provide a SILAS™ system.
