Water is the main stimulus for the development of microorganisms, and its flow has an important role in the spreading of contaminants. In hospitals, the water distribution system requires special attention since it can be a source of pathogens, including those in the form of biofilms often correlated with resistance of microorganisms to various treatments. In this paper, information relevant to cases of nosocomial infections involving water circuits as a source of contaminants is compiled, with emphasis on the importance of microbiological control strategies to prevent the installation, spreading and growth of microorganisms in hospitals. An overview of the worldwide situation is provided, with emphasis on Brazilian hospitals. Different approaches normally used to control the occurrence of nosocomial infections due to waterborne contaminants are analyzed, and the use of the polysaccharide chitosan for this specific application is briefly discussed.

This work presents the modeling and simulation of a hydraulic network with four nodes and two branches that form a two-level water distribution system. It also proposes a distribution of hydraulic valves that allows emulating a leak using a valve and different network configurations, e.g., simple ducts, closed networks and branched networks. The network is modeled in the steady state considering turbulent flow. Numerical experiments are performed, and the results show that the proposed network is useful for the design of leakage diagnosis and control algorithms in different configurations and leakage scenarios.

Clean water management is managed by a Perusahaan Daerah Air Minum (PDAM), which is centered on each local government. The distribution of water to consumers cannot be done evenly because of the water distribution system and manual monitoring. Overcoming these problems, the Water Distribution Equity System to Consumers can be used to monitor and control water distribution. This system regulates the debit and time zone for water distribution to consumers. Water discharge is detected by the water flow sensor, and  the valve is connected to the servo and time zone using RTC DS1307. The water pump is controlled to maintain the volume of water in the reservoir. The water level in the reservoir is detected using the HC-SR04 ultrasonic sensor. Water distribution is monitored on PCs (Personal Computers) and smartphones using Delphi programming and Thingspeak. The reading of water discharge is generated during peak use times for each faucet is 1.9: 1.8: 1.8 while at the time of normal use the ratio of the initial distribution to each faucet is 2.5: 2.3, 1: 1, and 2.5: 2.3.

This paper presents the Object-Oriented Knowledge Engineering (OOKE) methodology and its application in developing an expert system. OOKE is an expert system development methodology which incorporates the conceptual modelling tool of Inferential Modelling Technique into the analysis model of the Object-Oriented Software Engineering methodology. It was applied to develop a supervisory and decision support system for monitor and control of a water distribution system called the Water Advisor. The expertise, heuristics and reasoning knowledge of experts were acquired and then formulated in a model building process using the OOKE into a conceptual model which became the basis for a prototype expert system.
