RESIDENTS and visitors are being urged not to be concerned if they spot small plumes of red water and several oranges bobbing about in Bridlington Harbour this week.
Yorkshire Water is conducting environmentally friendly dye-tests and using a small number of oranges to help it build a greater understanding of how its sewer outfalls can impact on the quality of local bathing waters.
This involves monitoring how long it takes for the red dye and the oranges to reach the harbour from the Gypsey Race stream and the effect of underwater currents and tides in terms of what happens to them once they are there.
The oranges are being used for their visibility and buoyancy to make it easier for technicians to spot the dyed areas.
Bathing water strategy manager Lee Pitcher said: “The dye itself is completely inert and is not harmful in any way to plants and wildlife.
“Over the course of Monday, we’ll be releasing a small amount and then tracking where it goes.
“This testing is hugely beneficial as it should give us a clearer picture of how our outfalls operate and the impact they have, helping to inform our planning around £110m investment which we announced in November 2010.”
Dye-testing was undertaken in Scarborough and Bridlington back in 2008, with similar work recently completed at Filey and Skipsea among others.
It is part of the company’s £110million programme which sees them working alongside the Environment Agency, local councils and tourist body Welcome To Yorkshire, to transform Yorkshire’s beaches and bathing waters into some of the best in Europe.
