Nature Clear GWS10
When applying to your local council for approval to install a waterless composting toilet the council will want to know what you plan to do with your grey water (laundry, bathroom water). Their standard requirement is a holding or septic tank. Unfortunately these tanks only clarify the water and allow bacteria to build up and generate foul odours. The water treated in a Nature Clear GWS10 Greywater Treatment System is clear and almost odourless.
Nature Clear GWS10 provides a simple and low cost effective means of treating Greywater. Not only is the equipment low cost, but also, if your site is suitable, the only significant excavation work required to install the system will be the trenching. The ongoing costs will be similar to those of a standard septic system .
The Nature Clear GWS10 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 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 six 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 will 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.
