The purpose of this project was to evaluate the application of the Hazard Analysis Critical Control Point (HACCP) system, a risk management tool, to better protect water quality in distribution systems. HACCP was first conceived in 1959 by the Pillsbury Company to improve food safety for NASA?s manned space missions. Since the 1980s, HACCP has been widely adopted by the food and beverage industry worldwide, where it forms an important part of their food safety plans. Since the mid-1990s, HACCP has been applied by a number of individual drinking water systems and has been incorporated into many drinking water regulatory requirements and guidelines around the globe. The HACCP system complements the current U.S. approach to managing distribution system water quality centered on water quality monitoring and regulatory compliance. It will help utilities focus resources on key risks and improve emphasis on operational processes and controls. The recommended approach is to implement quality assurance programs such as HACCP prior to experiencing waterborne disease outbreaks or other contamination events. A recommended first step is to improve utility programs to meet the AWWA Standard G200-Distribution Systems Operation and Maintenance. The utility may then consider implementing ISO 9001 and 14001 or an integrated management system.
Utilities need guidance related to appropriate flushing velocities in order to achieve a balance between water quality improvements, demand for O&M resources and water conservation. The objective of this project was to determine the range of flushing velocities required to dislodge and remove various accumulated materials from water distribution mains based on site-specific conditions.Twelve utilities from 3 countries (USA, UK, Australia) participated in this study.Research Partner:KIWAOriginally published by AwwaRF for its subscribers in 2003?This publication can be purchased and downloaded via Pay Per View on Water Intelligence Online - click on the Pay Per View icon below??
