A sewerage system is not only the most concerned construction, but also the significant indication of a country development. One of the purposes of the sewerage system is to maintain public sanitary and urban stream water ecosystem. As the cost of a sewerage system contains the installation of pipelines and the construction of the treatment plant. However the installation of pipelines dominates the major costs. Therefore, the preliminary design and organization of the pipeline system became a more important issue. Due to the limited budget, a practical and economical project is discussed in this thesis.
In a well developed city, existed geographic factors, and barriers from other underground pipelines confine the design of sewage works. As a result, this research is logically planned under the fixed pipe network. First, the sewage flow, water table, diameters of pipelines, slope, water velocity, and burying depth were analyzed. These factors affect the cost of pipeline construction. Then, the cost function from regression analysis and application system was employed to establish the best solution under the controlled running condition in different stages. Finally, an optimal policy is obtained to make the computing of piping handling and laying, which is then incorporated into a computer program. This project is predicted to save the construction time and also the cost of for sewage works. Hopefully, it will become a prevailing method to be followed.
The purpose of this study is to establish a computing system for a sewage system design. One can easily access and familiar with the system by simply store the basic information and even edit the settings. According to the case study, this system design is positive and effective in saving the construction cost and makes it possible.
