Technology tells the tale

Atlanta realized that education could be an important first step in bracing citizens and local officials for the multi-billion dollar price tag to repair an outdated sewer system. To help customers understand what is involved in delivering drinking water, and how wastewater is collected and treated, they engineered a multimedia program to get the message across. Presenters of Using Multimedia to Sell Your Rate Increase (Sunday, Sept. 10, 3 to 3:50 p.m.) include Marilyn Johnson, Atlanta's director of public participation for watershed management; Karen Rich, president of Karen Gill Consulting; and Marla Hill, public information and outreach manager with CH2M Hill.

Batten down the hatches

Do you know the threshold of your municipality's sanitary sewer system? How big a storm would it take to overload your system? Will new development in the area worsen the problem? Attending the session Is Your Sewer System Ready for the Next Big Storm? (Monday, Sept. 11, 11 to 11:50 a.m.) can help you use technology such as geographic information systems to track existing and project future sanitary flows, and use modeling to gauge system performance. Robert S. Czachorski—an engineer with Orchard, Hiltz & McCliment—will discuss the basics of wet weather flows, and discuss the concept of antecedent moisture conditions.

Going with the flow

Is it possible to meet the demands of new development without having the required permanent sanitary sewer capacity in place? Through the use of innovative approaches and temporary measures, cities can avoid the construction of new main interceptions. In Stretching our Trunk Sewer Service Area Wednesday, Sept. 13, 9:30 to 10:45 a.m.), Lincoln, Neb.'s superintendent of wastewater collection Brian Kramer, and Water Resources Modeling president and senior engineer Robert W. Carr, will discuss how agencies can use tools like temporary lift stations, capital improvement projects, dynamic modeling, and developer agreements to get the job done.
