The Technical Area of the AWWOA web site is provided for any Operator that would like some insight into various topics of interest within the field of water and wastewater treatment. Most all of the papers presented come from technical sessions held during the Associations' Annual Seminars. However, if any of you would like to have a paper published on this site, we would welcome your effort. E-mail awwoa@awwoa.ab.ca with your information and arrangements can be made to publish your paper.

Here you will find a number of papers that were presented at the AWWOA 2005 Annual Seminar held in Banff. A short synopsis details each of the papers presented.

Preparing a Regional Water Emergency Response Plan - A Guide for the Planner

A paper by Dan Rites with the Regional Water Customers' Group
ABSTRACT:

In mid-2002, the Regional Water Customers' Group brought together representatives of the 40 municipalities it serves in the Alberta Capital Region to begin developing a water emergency response plan for the Regional Water Service Area. The objective was to develop a plan to coordinate and guide decisions by the Customers' Group in the event of an emergency created by a water shortage.

The plan was intended to:

The following paper demonstrates how the Regional Water Customers' Group prepared their Emergency Response Plan.

Integration of Drinking Water Source Protection into the Watershed Protection/Management Process

A paper by Randy S. Lewis, P.Eng. Source Protection Engineer with the Drinking Water Branch, Alberta Environment
ABSTRACT:

Source protection, in general, is about protecting surface water and groundwater for future use. In this context, drinking water source protection is about providing an initial barrier in a multi-barrier approach to providing safe drinking water. The methods and efforts in protecting the water in a watershed for any use are similar and can incorporate the identification and control of contaminants of concern for various interests. Source protection from a point-source point of view already exists in the province but there is a need to better control non-point sources. In addition, the inventory of contaminants needing control can be better defined on a smaller scale, such as the watershed rather than the province as a whole. This paper provides the general considerations in order to incorporate source protection for a drinking water supply into a watershed protection plan. The plan must have an inventory of the possible contaminants within the watershed, identify the risk of the contaminant entering the supply, evaluate the options or barriers available to mitigate the risk, and provide a means to put appropriate barriers in place to reduce risks to acceptable levels.

Successful Implementation of Biological Nutrient Removal
at Calgary's 500 ML/d Bonnybrook WWTP

A paper by Paul Do, Prasanna L. Amatya, and Wolf E. Keller
Calgary Wastewater Utilities and Environmental Protection
Bonnybrook Wastewater Treatment Plant
ABSTRACT:

Calgary is the largest city in the Province of Alberta, Canada, with a 2003 population approaching 1,000,000. The City of Calgary owns and operates two wastewater treatment plants, Bonnybrook and Fish Creek, which together provide treatment to 100 percent of Calgary wastewater prior to its discharge to the Bow River. The Bow River is a world-class sport fishery, an important natural and recreation resource, as well as the water supply source for several downstream communities. It is one of the many tributaries of the Saskatchewan / Nelson river system, that rise on the eastern slopes of the Rocky Mountains and flow generally eastward into the Hudson Bay.

Bonnybrook is a 500,000 m3/d biological nutrient removal (BNR) plant; while Fish Creek is a 72,000 m3/d oxygen activated sludge (UNOX) plant. Exhibit 1 presents the locations of the two Calgary wastewater treatment plants (WWTP's) and their respective sanitary sewer catchment areas.

This paper presents the 1989-1999 implementation of the various biological phosphorus and nitrogen removal (BNR) processes, which was carried out in 4 separate stages at Calgary's 500,000 m3/d Bonnybrook advanced wastewater treatment plant. The paper also summarizes Bonnybrook's successful BNR experiences in terms of 90 - 100% chemical cost savings, the production of an excellent effluent quality being much better than that produced by the conventional activated sludge process and consistently meeting all Alberta Environment's stringent effluent limits, as well as the various advantages and disadvantages associated with the BNR processes.
