  "text": "Technique\nDescription\nMinimise use of water.\nThe volume of waste water can be reduced by using techniques such as pre-cleaning (e.g. mechanical dry cleaning) and high pressure cleaning.\nSegregate rainwater from waste water streams that require treatment.\nSegregation is carried out by implementing separate collection in the form of properly designed and maintained drainage systems.\nTreat waste water.\nTreatment can be performed by sedimentation and/or biological treatment. For waste water with a low pollutant load, treatment can be carried out by means of swales, ponds, constructed wetlands, soakaways, etc. A first flush system can be used for separation before biological treatment.\nLandspreading of waste water e.g. by using an irrigation system such as sprinkler, travelling irrigator, tanker, umbilical injector.\nWaste water streams can be settled, e.g. in tanks or lagoons, before landspreading. The resulting solid fraction can also be landspread. The water can be pumped from the stores and brought into a pipeline that goes to e.g. a sprinkler or travelling irrigator, which landspreads the water at a low application rate. Irrigation can also be carried out using equipment with controlled application to ensure a low trajectory (low spread pattern) and large droplets.",
