Otterbine and Sentinel in Dural

Otterbine giant fountain with triad nozzle and sentinel deluxe Aeration Station 16000 - Sydney


Otterbine Giant Fountain - Dural
Clearpond in conjunction with David Ting “The Garden Guide” were asked to recommend a suitable fountain/aeration device to not only make the client’s residential dam clearer and healthier but to also provide an attractive fountain display for the client, their guests and visitors to the property.

The client’s dam is purely rain-runoff dependent and therefore subject to extended periods of stagnant water. With an annual heavy load of organic matter such as leaves, nuts and pollen from the gum trees surrounding the dam the recommendation was for the installation of a fountain and sub-surface aeration which would agitate and oxygenate the water allowing for sludge and debris decomposition by bacteria producing a cleaner and clearer dam.
The Solution
Due to the spectacular location and view of the dam from the residential premises on the property, it was an ideal opportunity to install a magnificent fountain display which would also provide substantial aeration to the dam.

In agreement with the client, the Otterbine Giant Fountain with a Triad nozzle was selected which would be run intermittently in conjunction with a Sentinel 16,000 Deluxe Aeration Station powering four double air diffusers running 24 hours a day.
The diffusers were equally spaced around the dam increasing aerobic activity in the dam in turn reducing the nutrient build up from the historically high organic load. The dam edges were also cleaned and excavated to remove excess sludge to achieve healthy, clear water suitable for paddle boarding and other recreational activities.

Product Information: - Sentinel Deluxe Aeration Station 16000
The Sentinel 16000 Deluxe Aeration Station is ideal for dams and lakes where aeration is required to provide oxygen to the deep areas of the water body to solve any thermal stratification issues as well as enable sludge eating bacteria to thrive in the now oxygen rich deeper layers of the lake provided by the air diffusers. As the 16,000 set comes complete with four double air diffusers it is perfect for lakes where there is not only varying depths but also a large surface area ensuring an even oxygen content throughout the lake.

Each system is a complete, easy to install package with a deluxe lockable cabinet complete with air compressor already installed, a cooling fan already installed and an electrical box/outlet already mounted and ready for you to connect the incoming power line to the compressor and cooling fan. Every compressor comes with a multi-valve outlet assembly, pressure relief valve and a pressure gauge and it is just a matter of simply setting the cabinet in the desired location, installing the air diffusers and connecting the Self Weighted PVC Airline. As each installation will require differing amounts of airline, Clearpond does not include any Self Weighted PVC Airline with the system, this can be cut to length when the system is ordered.

This system will improve water quality and clarity, improves Oxygen levels and increase bacterial action and will also eliminate thermal stratification – the mixing action of the diffusers creates more uniform water temperatures and promotes healthier fish.
