Six Otterbine sub-surface aerators installed in lakes at the new Rockliffe Hall Hotel, Golf & Spa development, near Darlington, are playing a big part in maintaining the complex’s luxury standards by ensuring the water is kept sparkling clean.
Taking its water supply direct from the adjacent River Tees, the largest lake is used for irrigation storage and has been designed so that the top 30cm of water can be utilised for irrigation purposes.
The two smaller lakes, meanwhile, benefit from Otterbine’s newest innovation – the Air Flo 2 sub-surface aerator. Energy efficient and quiet, this fine-bubble diffused aeration system features Gast piston compressors, which allow it to operate at depths of up to 12m. This made the system ideal for the two lakes, which are four metres deep.
