45、n CSA/5Canadian deviationsIntroductionAdd the followingA reliable supply of safe drinking water that is visually appealing and readily available is a fundamental expectation among Canadians. Similarly, Canadians want wastewater (including all solid and gaseous residues of human waste) to be disposed
46、 of or reused in a safe and environmentally sustainable manner. Utility owners and operators strive for continuous improvement of their water services and the professional development of their staff to ensure that they are able to meet and exceed users needs and the applicable laws and regulations f
47、or their area of jurisdiction.The new International Organization for Standardization standards, ISO 24510, ISO 24511, and ISO 24512, have been developed to provide guidelines for the improvement of service to users, the management of water utilities, and the assessment of water services. These Stand
48、ards were published in December 2007 and are now being implemented throughout the world. In the context of these Standards, the word “water” is intended to cover drinking water and wastewater.The CSA Technical Committee on Water Quality Management Systems was established to review these Internationa
49、l Standards and help to bring about their application to Canadian water system management. The intent is to ensure that Canadian utilities and stakeholders have access to the best and most current guidelines available. The ISO Standards, adopted with Canadian deviations as CAN/CSA-Z24510, CAN/CSA-Z24511, and CAN/CSA-Z24512, present a significant advance in using performance indicators to improve the management of water services and systems and build on existing concepts for improvement in a uniform and internationally recognized manner.
