Construct a separate internal network for greywater system independent <strong>of</strong> black water and also a piping system for treated greywater or a feeding by gravity system to be used directly on site. 2. Greywater may be collected by putting a bucket under the sink and then carrying the bucket <strong>of</strong> greywater outside to the point <strong>of</strong> use and treatment. 5.7 Greywater Treatment Systems The greywater treatment system should have the following components: 1. The conveyance portion <strong>of</strong> the greywater system consists <strong>of</strong> pipes and valves that are needed to allow the discharge <strong>of</strong> the greywater when the system is under maintenance or the greywater is not needed or not working to the sewer system. 2. Appropriate drip irrigation system to distribute the reclaimed greywater through a network. 3. A pump is needed to pump the greywater at some point <strong>of</strong> the system if it is not possible to make use <strong>of</strong> feeding by gravity. 5.8 General Requirements 5.8.1 Health and Safety Requirements Domestic wastewater discharged to a sewer system represents the health conditions <strong>of</strong> each family living that area.
