Abstract:
The operation and maintenance of urban drainage facilities significantly impact the functioning of wastewater treatment plants and the quality of water environment. To evaluate the operation and maintenance situation, a quantitative evaluation system is developed, which is composed of a basic system and a correction system. The basic system includes operation and maintenance results, operation and maintenance process, complaint response, data compliance and emergency response and other indicators. Additionally, the correction system includes additional items, subtracting items and control items. This system emphasizes both result-oriented and process evaluation. It is applied to the quantitative evaluation of drainage facilities in B and G districts of Chongqing, and the evaluation results accurately reflect the actual operation and maintenance conditions of drainage facilities.
