Development of a Strategic Planning Model for a Municipal Water Supply Scheme Using System Dynamics

This paper reports the development of a system dynamics model for the strategic planning of a municipal water supply scheme. The model is capable of handling the critical variables that impact on the operations of a water supply scheme. The model was developed using the dynamo programming software to handle the process dynamics. Other supporting softwares—Fortran, Clipper 5, and Epiglue are used to handle data input, analysis and presentation of results in a user-friendly environment. The model was validated by applying it to the simulation of the University of Ibadan Water Supply Scheme for which extensive data of operations were collected over a period of ten years. The results obtained were found to be realistic and useful for the planning of plant operations. It is concluded that the model developed is sensitive to variable changes and has the capability of answering various operational “what-if” questions. As a strategic planning tool, the present model generates, for different scenarios, important operational information for the management of the water supply scheme. It is concluded that SD model is a useful tool to assist water managers and policy makers in making decisions and evolving strategic planning for water supply.

Domestic Water Supply Dynamics Using Stable Isotopes <i>δ</i>¹⁸O, <i>δ</i>D, and d-Excess

Surface water is the greatest contributor to many water supplies in urbanized areas. Understanding local water sources and seasonality is important in evaluating water resource management, which is essential to ensure the sustainability of water supplies to provide potable water. Here we describe the municipal water cycle of Columbus, Ohio, USA, using δ18O, δD, and d-excess, and follow water from precipitation through surface reservoirs to a residential tap between May 2010 and November 2011. We show that trends in water isotopic composition of Ohio precipitation have a seasonal character with more negative values during the winter months and more positive values during the summer months. The year of 2011 was the wettest year on record in Central Ohio, with many months having high d-excess values (>+15‰), suggestive of increased moisture recycling, and possibly moisture introduced from more local sources. Tap waters experienced little lag time in the managed system, having a residence time of ~2 months in the reservoirs. Tap waters and reservoir waters preserved the isotopic signal of the precipitation, but the reservoir morphology also influenced the water residence time, and hence, the isotopic relationship to the precipitation. The reservoirs supplied by the Scioto River function like a river system with a fast throughput of water. The other reservoirs display more constant solute concentrations, longer flow-through times, and more lacustrine qualities. This work provides a basic understanding of a regional water supply system in Central Ohio and helps characterize the water flow in the system. These data will provide useful baseline information for the future as urban populations grow and the climate and hydrologic cycle changes.

基于“蓄排平衡”的城市市政-水利综合排涝探究与实践

叠压供水系统对市政管网的影响分析

叠压供水充分利用管网余压进行变频恒压供水,具有节能、供水水质稳定等优点。然而叠压供水系统直接与市政管网相连,启动时会引起接入点及管网上下游的流量和压力波动,对市政管网输送水量变化和压力变化带来影响。以江苏省JT城区的市政管网为研究对象,采用EPANET软件执行延时模拟、HAMMER软件执行瞬时模拟,分析叠压供水系统对市政管网的影响程度和规律,并确定了两个评价指标:最低市政供水压力要求和系统接入点运行压降要求。结果表明,叠压供水系统对市政管网的影响与小区入住率、用水时段、叠压数量等因素有关;小区附近叠压供水系统数量越少、分布越稀疏,多叠压供水系统运行时接入点压降就越小。当实际应用中影响超出安全范围时,建议通过优化控制方式和供水方式缓解影响,保障供水安全。
