Wastewater with high organic content and high load of fats, oils, oil derivatives without pre-treatment are unsuitable for natural wastewater treatment systems.
Natural treatment methods are used either as only WWT solutions for dwelling, hotels, recreational facilities, restaurants and summer camps, if it is allowed by national legislation, or for polishing after septic tank or packaged WWT plant discharge or for infiltration of treated wastewater.
Constructed treatment wetlands represent a biological treatment stage – secondary and/or tertiary. It is based on slow filtration of pre-treated wastewater. It may also be used for tertiary treatment of effluent from WWT plants with activated sludge process.
Constructed wetlands are constructed filtration systems planted with vegetation (most often reed) with defined filter material and direction of wastewater flow. The basic principle of this method for sewage treatment is the flow of wastewater through the filtration system, which is planted with vegetation. There are three types of constructed wetlands used – sub-surface flow constructed wetland, surface flow constructed wetland, hybrid system – a combination of subsurface flow and surface flow systems.
Effluent after its treatment in the pre-fabricated WWT plant or septic tank trickles out of the pipes, through the gravel layer, and into the soil where additional treatment occurs. The filtering, which is characterised with suction velocity, is strongly dependant on the type of soil. Therefore, the area of infiltration field should be designed individually in the each particular case.
Since the sewage treatment result is not easy to control, the infiltration field is not used for wastewater treatment, but only for treated wastewater discharge after pre-fabricated WWT plants or septic tanks. Infiltration fields are not suitable for the regions with high level of groundwater.
VillageWaters suggest most effective wastewater treatment solutions in scattered dwellings households, which use their own, independently operated water purification systems.
Environmentally oriented families and homeowners, who live in scattered dwellings areas, where connecting to larger wastewater plants is not option because rural distances.
