Michigan’s Water Well Disinfection Manual
Natural ground water from all but very shallow aquifers is considered free from pathogenic (disease causing) bacteria and viruses (Bouwer, 1984). As such, ground water obtained from properly designed and constructed water wells is generally free of disease causing bacteria, and continuous disinfection is unnecessary (Roscoe Moss Company, 1990). However, disinfection of a new or repaired water supply system is needed to remove contaminants introduced during the construction or repair process (Driscoll, 1986). Existing water supplies require disinfection when routine maintenance of the system takes place, or when the results of water samples show the presence of coliform bacteria (Driscoll, 1986). This manual provides information to water well drilling contractors, local health department (LHD) sanitarians, and others involved in potable water system construction, operation, or evaluation.

Design of Water Hammer Shock Absorber
Abstract:
In the piping system, water hammer or hydraulic shock is a major issue that engineers need to consider. Water hammer is a phenomenon that leads to shock waves in the fluid due to rapid closing and opening of the valve, which can affect pipes, valves and gauges in any water, gas, or oil applications due to the sudden transient event. It is there for every system that has a flow of fluid through pumping such as houses, hospitals, and influences major effectiveness in the power plant. It occurs when there is a pressure difference in the pipeline leading to a loud noise. Specifically, this project is aimed to design a pipeline system and develop solutions to reduce the water hammer using a shock absorber. The main idea of the design project is to design a water hammer system using a shock absorber in order to reduce the shock waves of the pipes.
