The authors have put forword an idea of that the planning optimization scheme on elevation control of drainage pipelines in coastal plain,such as plastic sewers & core mould vibration-reinforced concrete rain-water pipes are applied,and sometimes a steel short pipe coated by special painting instead of sewer directly passes through a rectangular rain-water inspection well,etc.
