Ice Pigging & Current Issues Affecting Water Tank Owners: Antennae, Coatings, Water Quality Management Tools for Water Tanks


This class was originally scheduled for 03/06/13 in Rockford, but due to a snowstorm, was rescheduled to 04/09/13 in Rockford.

SUMMARY: This seminar reviews current issues affecting water tank owners in the areas of Placing antennae on tanks, Coating Renovations, and sustainable tools aimed at fighting water quality issues within the tank, such as: mixing systems, bio-film removal, in-tank aeration systems, residual control systems, and regular maintenance practices. Ice pigging for water mains will also be discussed.

The distribution system itself provides multiple opportunities to improve water quality with relatively small capital and operational expenditures. By employing new sustainable tools distribution system water quality can be effectively managed. Regular chemical cleaning can quickly and efficiently remove bio-films and inorganic deposits on tank surfaces and other contact points within the distribution system. Active tank mixing can prevent thermal stratification, lower residual loss, and reduce or eliminate nitrification risk. In-tank aeration systems can directly remove THMs and other volatile components. Residual control systems can automatically monitor and adjust disinfectant levels within storage tanks so that residual levels can be maintained across an entire distribution system. Ice pigging can be used to clean distribution system piping to remove accumulated sediment and biofilm. And sustainable tank asset management programs can provide not only protection of the physical asset, but also directly impact water quality management within the storage tank and distribution system.

While these sustainable water quality management tools can be implemented separately, their combined adoption throughout the distribution system provides a synergistic holistic approach to water quality management. Case studies will be presented supporting these affordable tools as sustainable best practices. Recent AWWA Opflow articles featuring these tools will also be reviewed.

PRESENTER: Bill Murfree, Utility Services, Inc. & Erik Otten, Tnemec / Taylor Coating Sales Inc.
