Gurney Environmental have completed the installation of a 2nd ResMix 1000 ‘Source Management’ system for Jersey Water in Grand Vaux Reservoir.

The ResMix system — ordered by Jersey Water in March this year — follows the installation of a similar system at the Jersey Water Reservoir, Val de la Mare last year.

Jersey Water continue to see the benefits of adopting the ResMix system and have enjoyed significant savings in energy and treatment costs at Val de la Mare, which was installed this time last year.

The ResMix ‘Source Management’ system improves and maintains water quality in the reservoir with the benefit of downstream savings at the water treatment works, which has made it the first choice for many water utilities.

Grands Vaux Reservoir

Grands Vaux reservoir is located in St. Saviour parish and was constructed in 1952. The reservoir holds just over 190,000 m3. The dam is 141m long and 15m high. Located near St Hellier, Grands Vaux Reservoir was the first big development by the Water Works company after the occupation of Jersey during the second World War.


We've already found that the ponds work a lot better, they are a lot cleaner and functionally look a lot better than what they were previously. It seems to be working at this stage, so we're quietly confident that it's going to be a good investment.

...there is no doubt about it, the ResMix system works! Having started with a volatile and inconsistent chlorine residuals in our supply, we are now using the WEARS product to mix and dose our tanks. We are not alone in our experiences here. All I can say is that the results speak for themselves.

Adding the Accel-o-Fac® system to South Gippsland Water treatment cells where traditional surface aeration was previously used allowed the corporation to significantly reduce energy use. The savings in kWh are excellent with one application saving 72% in energy compared to the previous year.

The fact that there is no associated sewage odours [with the Accel-o-Fac wwtp] meant that the system could be located relatively near to the village, and, after 10 years of use, no sludge removal has been needed.

These results show that the [ResMix] mixer is providing a fully mixed water column and preventing conditions for manganese and nutrient release from the sediments.

We are very pleased to be using this innovative management system in the reservoir at Pontsticill. This investment will improve the water quality for customers in the area and ensure they continue to receive a top quality supply of drinking water long into the future.
