Graf UK wastewater treatment tanks



Wastewater treatment system by Graf UK is first to break ground by the River Tay.

An 80-acre luxury holiday park on the banks of the River Tay has broken ground, thanks to a 300-person wastewater treatment system from Graf UK.

River Tay Leisure Park, which is being developed in a former sand and gravel quarry between Stanley and Luncary, was bought by the award-winning Verdant Leisure group earlier this year (2022), with planning permission already in place.

Verdant Leisure, who already operate 12 other bespoke holiday parks in Scotland, Northern England and Devon, were happy to sanction the previous owner’s choice of the Graf UK system which meets the stringent effluent levels set by SEPA (Scottish Environment Protection Agency).

“It was important to us that we invested in a system that met our requirements in terms of quality, whilst reducing the impact on the environment. Graf are well respected and highly rated, and it seems a very robust and efficient system. Most importantly, it can be scaled up if required so if we need greater capacity at any stage, it’s fairly simplistic to put that in place,” said Verdant’s operations director George Hope.

Graf UK’s 300-person Klaro system using SBR (Sequence Batch Reactor) technology and three large Carat XXL tanks, which are manufactured from 100% recycled plastic, was installed over four weeks in the spring by Graf UK approved service providers and groundworks contractors McIntosh & Robertson, based in Gellyburn Quarry in Murthly, near Perth.

While they are approved Graf UK installers, and had installed several smaller domestic Graf UK septic tank and wastewater treatment systems in the past, this was by far their largest to date. As well as wastewater treatment, the Carat tanks were specially developed for rainwater harvesting and firefighting.

And while the tanks and associated pipework have been installed, and backfilled with 10mm gravel, the compressor and control system have to wait until the pumped outfall system has been completed.

Director Derek Robertson explained that the Graf tanks were installed at a higher than normal level to cater for the particular ground conditions.

“Although the system is not operational yet, any dealings with Graf in terms of delivery and advise have all been extremely positive,” he said.

Russell Mann, sales director of Filpumps, who specified the Graf UK system, said: “Having been involved at the beginning of the project, where we drilled and installed the private water supply, we were delighted to latterly provide and commission the Klaro waste water system for the park. This system is the perfect fit for the holiday park and will give the quality and reliability needed for a site of this scale.”

When open in spring 2023, River Tay Leisure Park will offer holiday accommodation and holiday home ownership alongside a bar and restaurant facility. It is close to miles of beautiful walking routes, with Perthshire home to world-class golf courses and some of Scotland’s best fishing, not to mention otters and beavers.
