- Abstract:
- Rainwater and sewage diversion is one of the effective measures to improve the environment of the old urban area. However, the distribution of the underground pipelines are complex in the old urban area. It is difficult to reconstruct the pipelines by using the traditional gravity drainage technology. In Weifang Binhai old urban area, the vacuum drainage technology is used for sewage collection in rainwater and sewage diversion reconstruction project. It shows obvious advantages in pipe network construction and maintenance comparing with gravity drainage technology. The transformation method of rainwater and sewage diversion, and the design key points of sewage volume, vacuum pumping station, collection box, vacuum pipeline and electrical system were introduced, which can provide reference for similar projects.
