- Abstract:
- The high-density built-up area of Maozhou River basin is characterized by high population, traffic and architecture density, which cause some problems to the septic tanks, such as wear-out, aging, inadequate scale and lack of maintenance. This project collaborated different departments for unified management to survey, repair and renovate 31 447 septic tanks within the built-up area. The septic tanks were inspected in three stages before, after cleaning, and after renovation, to accomplish information statistics and repair supervision. There were two cleaning approaches, including by suction-type sewer scavenger or by integrated feces treatment facility, depending on environmental conditions of the high-density built-up area. The feces were processed by dehydration, pressing and incineration. The defective septic tanks were repaired or rebuilt. After the completion of the project, the septic tanks were entrusted to the maintenance unit for unified management. The project realized unified management of three stages, including management, implementation, and maintenance. Meanwhile, a renovation plan was formulated in accordance with characteristics of the high-density built-up area, which can provide reference for the implementation of follow-up projects.
