Towards a Sustainable Small Non-Community Drinking Water System in Ontario: Owners’ Risk Awareness and Perceptions to Water Safety
In Ontario, small non-community drinking water systems are defined as systems that make drinking water available to the public and are not connected to a community drinking water system. This study, using qualitative research approach, examines the risk awareness and perceptions of small non-community drinking water system owners in providing safe drinking water to their clients and protecting their water source. Our study yields the need for developing a sustainable operation model for small non-community drinking water systems. The study results provide recommendations to the regulatory agency for effective and efficient administration of the program such as offering customized and affordable training opportunities and developing effective communication strategies for owners and operators.
The North Xinjiang Water Supply Project is a large and long distance water supply project,of which the construction organization design is quite complicated.Within the construction design,the key technical points are the constructions of a tunnel in weak rock,three kinds of inverted siphons and a large channel in desert,and the plannings of both borrow area and the balance of the earth-rock excavation and fill as well as the construction water supply,etc.In conjunction with the construction of the project,the problems given above are briefly discussed herein.
