摘要

本文建立了一个劣化模型,并用于模拟配水管网的生命周期。然后,评估了两种策略——泄漏修复和管道清洁——以恢复其满足需求的能力。为了实现退化模型,考虑了以下参数:消费者群体的增长、泄漏率的增加、功能管道的退化和泵的水力容量的降低。对于渗漏修复,在达到最小参考值之前,在整个WDN中都考虑了固定的水损失减少率。对于管道修复,每年以网络总长度的1%的速率考虑倾斜。在每种康复策略中,都使用净现值进行了成本效益分析。结果表明,这两种方案都可以恢复WDN的容量,管道清洁具有更好的经济影响。

Rehabilitation of water distribution networks: when and how to rehabilitate
In this paper, a deterioration model is created and used to simulate the life cycle of a water distribution network (WDN). Then, two strategies – leakage fixing and pipe cleaning – are evaluated to rehabilitate its capacity to attend the demand. In order to implement the deterioration model, the following parameters were considered: growth of the consumer population, increase in leakage rate, functional pipe deterioration and reduction of the hydraulic capacity of the pumps. For the leakage fixing, a fixed reduction rate in water losses was considered throughout the entire WDN until a minimum reference value was reached. For pipe rehabilitation, leaning was considered at a rate of 1% of the total length of the network per year. In each of the rehabilitation strategies, a cost–benefit analysis was carried out using the net present value. The results showed that both alternatives can restore the capacity of the WDN, with the pipe cleaning presenting a better economic impact.

期刊介绍: Journal of Hydroinformatics is a peer-reviewed journal devoted to the application of information technology in the widest sense to problems of the aquatic environment. It promotes Hydroinformatics as a cross-disciplinary field of study, combining technological, human-sociological and more general environmental interests, including an ethical perspective.
