RHS WISLEY CALLS

ON OTTERBINE

FOR SUSTAINABLE RAINWATER SOLUTION

RHS Garden Wisley has chosen Otterbine to provide its flagship garden with sustainable irrigation .
Otterbine ’ s 25HP Polaris Giant Fountain was installed at RHS Garden Wisley in Woking as part of the Royal Horticultural Society ’ s project to create a new rainwater capture lake , providing great quality irrigation to one of the largest plant collections in the world .
In today ’ s climate , water can be a scarcity and harvesting rainwater supports the conservation of this vital resource . The water has to be good enough quality to use though which is where Otterbine ’ s 25HP Giant Polaris fountain steps in .
Matthew Pottage , curator of RHS Garden Wisley , explains : “ The Giant fountain is installed in our new lake which is connected to our garden irrigation system . The lake collects winter rainwater for summer irrigation and the Otterbine aerating fountain makes the water good enough to use .”
Otterbine ’ s fountains have the highest oxygen transfer rates in the industry and the Polaris is the brand ’ s largest floating fountain . The geyser-like spray of the Polaris throws water droplets into the air where they attach to oxygen molecules that can then be absorbed into the lakewater .
Matthew , who oversaw the aesthetic of the new landscape and horticulture around the lake , explains there were additional reasons for choosing the Otterbine Giant Fountain : “ The Wisley is one of the UK ’ s most visited and best-loved gardens , attracting around a million visitors each year and we wanted to use the opportunity to create a new atmosphere and beautiful place for visitors to enjoy and relax at Wisley .
“ The lake is designed in an ornamental fashion and the fountain ’ s visual beauty and the fact that it muffles noise disruption from a nearby road helps bring a sense of theatre and peace to the space ,” says Matthew .
Another benefit of the Otterbine Polaris Giant fountain is its unique launching system that eliminates the need for cranes during installation in most applications , despite its size . Miles Water Engineering was responsible for the build of the lake and the subsequent fitting of the fountain . “ The whole thing was easy and efficient . We are very grateful for that ,” Matthew comments .
Installing the new rainwater capture lake is not the only change to the grounds that RHS Wisley is undertaking . Matthew says : “ We are planning a massive new landscape of grasses and perennials with Piet Oudolf , a world-renowned planting designer .”
