Disinfection ensures that water being drawn from the storage system is free of harmful pathogens and organisms. These contaminants need to be neutralized to maintain the highest water quality possible and is achieved by either chemical treatments such as chlorine or ozone, membrane processing, or ultraviolet light (UV). UV is probably the safest disinfection or a combination of treatment processes can be used in association with a fine sediment filtration to remove total suspended solids (TSS) which improves the disinfection process.
Disinfection leads to source water utilisation which is facilitated by a controlled pressure pump system. The pressure pump would be specified according to the point where the water is needed, the volume and velocity required for the application like taps in a house, yard or for larger applications like for landscape architecture, public space maintenance and sports fields irrigation, air-conditioning plant make-up water, process cooling, agricultural watering or any application that does not rely on potable water.
These applications represent up to about 70% of all our water needs.
Water use is often taken for granted but that does not happen without sophisticated control occurring somewhere in the background. Sparkle Water has developed the WiWo water source controller that is available in a range of sizes for the performance required. The WiWo is a change-over device to priorities the use of alternate water source such as rainwater / stormwater storage from harvested rainwater and at the same time managing the efficient use of pumps, disinfection and managing the water quality of the stored water source whilst it is available. WiWo manages the water demand and ensures water is available even if the stored water is used up or is not suitable for use but ensures that mains water is available until additional alternate water source is replenished or power is restored to drive the reuse system.
