3.2.2 Fresh water pool in wetlands
The previous subsection 3.2.1 established that waste water should not be disposed off in gullies which become a link in major rivers forming the riparian areas. The waste water should be conveyed to form pool and create wetland that will not pollute fresh waters in rivers. In this subsection technology was introduced to treat wetland waste water to create fresh water. Fig 3 displays new innovative design of the fresh water pool.
