We were contacted by Wessex Water and asked if we could use the same technology and equipment to locate a leak on a pumped effluent water supply as we use on mains water leaks. Our answer was a positive one and we attended on site on May 14th. We used acoustic equipment to listen on each of the 6 effluent outlets on site and had one very positive point of interest at one of the outlets. The underground leak was marked in readiness for a repair by Wessex Water.
