Greywater breaks down much more rapidly than conventional sewage and has 1/10 the nitrogen.

Greywater is bath- dish and wash water. You should ask the community you live in what their rules and regulations are for treating and discharging the effluent.

If the installation will be on a lot that doesn't have good infiltration soils which the case often is in the archipelagos, the water can be treated in a septic tank followed by a sand filter and finally discharged in a constructed, built up soilbed and planter.

The most effective treatment takes place in the top layer of the soil where roots, soil bacteria and earth worms can finish the treatment.
