Nature Clear Greywater Sand Prefilter 450 Litre + 45 Litre Grease Trap
The Nature Clear GWS10 in combination with a 45L grease trap provides a simple, low cost effective means of (primary) treating grey water (waste water from bathroom, kitchen and laundry). Installation costs are low and ongoing costs will be similar to those of a septic system.
The filtration tank, which is less than 1 cubic meter in size, consists of a pine bark coarse filter on top of different grades of sand and gravel. The bark and filter cloth are provided but due to freight costs the sand and gravel should be sourced locally. Sample bags of these are provided with the system to assist with your selection of the correct grade materials.
The pine bark traps large particles not caught in the grease trap plus lint from the washing machine. The sand filter catches still finer materials, polishes the water and reduces the organic content of the water. The pine bark is separated from the sand by filter cloth. The filtered material and bark will compost over time and should be removed every twelve months and replaced with fresh bark, available from your local garden nursery. If your distribution area is down hill from the filtration tank your engineer should be able to design a distribution system without the use of a pump. If this is not the case you will need a pump and pump well.
The treated water must be distributed into trenches as specified by your engineer. Make sure his calculations of size do not include an allowance for toilet water, which would make them unnecessarily large and expensive.
