Lewis Mill, Md. Hanson Bros.
Pioneers in gravity operated greywater treatment systems. These outdoor planter beds have successfully been used for greywater irrigation and infiltration devices for well over a decade.

These systems should be planned as part of the lanscaping of the site. Attention needs to be given to the strata underneith so that water can drain away after infiltration.
