Our sewerage and waste water treatment plant is a Sand filtration system. The principal behind this system is effluent being collected in the primary green tank and seperated in a first spetic decomposition stage and transferred to a large sand filter where the effluent is aerobically broken down before seeping into the concrete well. By this stage the water is clean and suitable to use on the garden. Here a pump is triggerred by a float and pumps water out to a sub-surface irrigation area feeding plants with water. The aim is to not waste the water but rather to have it feed a fruit orchard or possibly a veggie garden.
