Rockliffe Hall golf course installs new Otterbine lake aerators

The largest of three lakes at Rockliffe Hall in County Durham, has four new Otterbine aerators, maintaining quality water for the course's irrigation system and wildlife alike.

The lakes and accompanying reed beds attract a great range of water fowl; from coots and moorhens, to geese, swans and greater crested grebe. 

Golf course manager Peter Newton – whose job it is to ensure water quality across the resort – said bearded tits and the allusive water rail have also been spotted recently.

"Bearded tits are classed as scheduled one protected birds and water rail are particularly rare. There aren't a lot of them left, with about 1,100 pairs estimated in the UK. It’s generally very secretive and not often seen, so is fantastic to spot them at the edge of our waters and is a great testament to the quality of our lakes," he says.

The new 3hp High Volume aerators have been installed in the main lake, which also feeds the golf course irrigation. They produce a fountain effect, which members are particularly pleased with, Newton said.

At 70,000 square metres in surface area and 130,000 cubic metres capacity, Newton said Rockliffe Hall’s main lake demands a powerful aeration system.

 "With the sheer volume of water, we needed something hard-working," he added. "If not, we get algae. The main lake has lots of alcoves where it tends to build up, which is not good for the irrigation system. It blocks up the nozzles, which means you don’t get a good distribution of water and it also gives off a bad smell.

"We wanted more water movement, which the new aerators have given us. We now have more gallons go through them per hour than the previous ones and there is no algae where we usually get it. When we go out on the lake in the rowing boat, the water is very clear – you can see right through to the bottom."

Now with 10 Otterbine aerators in total, the four new models join six smaller sub-tridend aeators already fitted at the other two lakes.
