本研究的目的是定义一种简单(且易于使用)的方法来平衡几个小型污水处理厂(SWWTP)的工作负荷。通过一个案例研究说明了这种方法，这是研究人员与意大利南部一家水和废水管理公司合作的结果。这一专题很重要，因为人员对污水处理厂的运营成本有重大影响，而概述的方法导致确保服务管理所需的最低工作人员数量。考虑了四种工作单位：工厂经理、工厂助理经理、实验室技术员和行政人员。为了开发一种实用、可行和易于使用的方法，只考虑种群当量(PE)和被管理的植物数量来评估工作量。该方法的核心是对所考虑的市的人事单位投入到污水处理厂运营的时间百分比进行评估。拟议的程序提供了一个有用的工具来平衡工作量，无论是在PE方面，还是在所管理的工厂数量方面，该程序很容易修改，以引入其他评估标准。通过使用熟悉的概念，如PE和被管理的工厂数量，该方法的方法很容易为管理层所理解。它也可以很容易地适应其他类似的情况。
The aim of the present study is to define a simple (and easy to use) method to equalize the workload of personnel operating several small wastewater treatment plants (SWWTPs). The approach is illustrated through a case study which is the result of collaboration between researchers and a water and wastewater management company operating in Southern Italy. The topic is important since personnel have a significant impact on the operating costs of SWWTPs, and the approach outlined results in the minimum number of staff being required to assure the management of the service. Four kinds of work units are considered: plant managers, assistant plant managers, laboratory technicians and executives. In order to develop a practical, feasible and easy to use method, the workload was evaluated considering only the population equivalent (PE) and the number of plants managed. The core of the method is the evaluation of the percentage of time that the personnel units devote to the operation of SWWTPs of the municipality considered. The proposed procedure offers a useful tool to equalize the workload, both in terms of PE and the number of plants managed, the procedure being easily modifiable to introduce other evaluation criteria. By using familiar concepts such as PE and number of plants managed, the approach of the method can easily be understood by management. It can also be readily adapted to other similar situations.
