Study on Water Supply and Drainage Facility Planning in Historic Towns - Case Study of Master Plan of Hengdaohezi Town

Abstract

In historic towns, the planning of municipal facilities varies from that in the common towns. To maintain the original styles and features, the curve dominants the street form in the planning. Additionally, combining with the rails and rivers which goes across the town, the water supply and drainage is divided into two areas at the line of the valley with the narrow and branching terrain. The existing pipeline network is taken into account as possible with the aim to compensate the skill deficiency and expand the service scope. Based on the prerequisite of lowering investment and maintaining eco-appearance, the rainwater will be collected and discharged near the site through two ways: natural drainage and pipeline network drainage. Water supply and drainage have set up the treatment facilities of water respectively, which will be planned and constructed by stages according to the development of towns.
