The first of two real-time water quality testing buoys has been successfully deployed at sea, just off the Kent coast near Tankerton.
The testing system works by fixing a monitoring device to the buoy, positioned around 400 metres offshore, which automatically measures the water quality every few minutes. The pilot, a UK first, will be able to give residents live updates on the water in one of the area’s most popular swimming locations. Southern Water and its partners will openly share the results with the public later this year, once calibration and further testing is complete.
The buoy at Tankerton is the result of a partnership between Canterbury City Council and Southern Water to deliver a 12-month pilot to test this type of technology, which hasn’t been deployed in this way before. Southern Water is also working closely with Havant Borough Council to launch another water quality testing buoy in Hayling Island.
The launch follows months of work by Southern Water, working alongside the Environment Agency, various local authorities, Proteus Instruments, and the University of Portsmouth.
Dr Nick Mills Head of Southern Water’s Storm Overflow Task Force said:
“This is a huge step forward in water quality technology in the UK and seeing this happen now is incredibly exciting as it is the culmination of many months of hard work. This shows that Southern Water is taking the lead on providing transparent data on the quality of our coastal waters and demonstrates what we can achieve when we all work together.
“We know our Beachbuoy service is incredibly popular, giving near real time data on the timing of storm releases, and this new technology will build on this success and deliver what is really needed – hard data on what the condition of the water really is at that moment in time. This is one of many technologies and techniques that we are exploring to better monitor water in some of our most popular bathing spots and keep people safe.”
Cllr Ashley Clark, Canterbury City Council’s Cabinet Member for Enforcement and Open Spaces, and a very keen sea swimmer, said:
“When it comes to dealing with sewage across the nation, there is a mountain to climb, and this will involve planners, developers and water companies coming together as well as proactive government support to deal with the rainwater from development that gets into the sewage system and overloads current capacity.
“This is a welcome step in the right direction and will provide useful reassurance to ensure the locals and visitors who use our coastline can do it safely and with a greater level of confidence. Sea bathing has many positive health benefits year-round in terms of exercise and a boost to the immune system. As a regular local sea swimmer I have noticed many more people are taking advantage of this. Our local water is the warmest in the UK over the summer period. For others who are both environmentally minded and cost conscious it can save on bath water!
“Locally, we have established a constructively-minded liaison group of three local councillors who meet with one of the directors of Southern Water to monitor progress and we are aware of other steps that are in the pipeline.”
