With the Ecotoilet system the separated urine goes to the grey water tanks.

It is fed into the top inlet (50-80 mm dia) and fills the first tank up to the connector pipe which joins the two tanks together.

When the level of the first tank reaches the height of the connector tube, fluid runs into the second tank.
Ecotoilets have a unique design which imparts a swirling movement to the fluid. This efficiently assists with the natural process which is carried out by the grey water tanks.

There is an external filter body which houses a standard cleanable filter, which stops anything bigger than 2-3 mm going off to the effluent treatment.

This whole system is up to the high standard of the rest of the ECOTOILET system and it is important that it is installed with the layout as in the diagram.

After the above treatment, the effluent is safe to be dispursed into the ground.

Normally about 10 to 20 m of perforated pipe (50-80 mm dia.) is placed in a trench as in the drawing.

Alternatively, a percolating garden may be used if the ground is not of a type that suits the trench - rocky, heavy clay, etc will cause this to be necessary. The small shrubs planted will treat the effluent.
