Engineers from Gurney Environmental have completed the installation of two further Wears ResMix ‘Source Management’ systems for Jersey Water at their Queen’s Valley and Handois reservoirs. Jersey Water now have ResMix ‘Source Management’ systems at all but one of their reservoirs.

Jersey Water continue to see the benefits of applying the ResMix ‘Source Management’ systems in their reservoirs and have benefitted from significant savings in energy and treatment costs as a result.

In Jersey Water’s latest Water Quality Report's Executive Summary, Chief Executive Officer Helier Smith made reference to the performance and effectiveness of earlier ResMix installations by saying:

“In order to better control the quality of the water stored in Val de la Mare Reservoir, a reservoir mixer was installed in March 2016 to replace the compressed-air bubble mixer. Based upon the first year of operation, the 'ResMix' has shown a stabilisation in raw water quality at reduced electricity costs of the previous mixer."

With an eye on the current heat wave being experienced, and with reports from a number of ResMix users of falling reservoir levels, one of the advantages of using the ResMix system is the elimination of aged water at the bottom of the reservoir. This ensures that 100% of the reservoir volume is kept in good shape at all times, and when the water levels are drawn down, that water is readily available for treatment in the water treatment works.

The ResMix ‘Source Management’ system improves and maintains water quality in the reservoir, eliminating manganese, controlling blue-green algae, eliminating aged water/ maximising water stocks, with the benefit of downstream savings at the water treatment works. This has made the ResMix system the first choice for many water utilities both in the UK and abroad.

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.

The Aero-Fac system at Windsor has to date met and exceeded our consent discharge levels, and we have been very happy with the system installed.
