EXHIBIT #1 Regular Council Meeting of 02/11/2008 WATER QUALITY IMPROVEMENTS CONTACT CHAMBER EFFECTIVENESS UTILITY COMMITTEE PRESENTATION January 14, 2008 Public Utilities Department Water / Wastewater Utilities

BACKGROUND The 2006 Water Quality Evaluation recommended the installation of contact chambers at all deep well sites to assist in stabilizing water chemistry. These chambers were identified as a necessary first step in addressing brown water issues.

BACKGROUND Source water has a natural demand for chlorine which results in chemical reactions. Due to limited piping available onsite from the wells, these reactions were occurring primarily within the distribution system (contributing to brown water issues). The installation of contact chambers at each deep well site provides adequate piping on site for these reactions to occur, prior to entering the distribution system.

ANALOGY Each well site can be likened to a factory, making a product for consumption. When making bread, for example, quality control is performed to ensure that the final product meets established standards. Would you perform quality control on the bread: – after mixing and rising of the bread; or – after mixing, rising and baking of the bread?

ANALOGY Just as baking the bread is a critical part of product development, the chemical reaction with chlorine is a critical part of the development of drinking water. The contact chamber is like the oven allowing for the reactions (baking) to be completed at the well site (factory) rather than within the distribution system (transport).

ANALOGY Performing quality control at the appropriate time ensures a more consistent product enters the market (distribution system) and is provided to the consumer.

CHAMBER #1 – WELL #13R The first contact chamber was installed in 2007 at Well Site #13R (Bayard Avenue). The contact chamber was brought online in December 2007.

CHAMBER #1 – WELL #13R In order to verify the effectiveness of the contact chamber, data was collected before and after the chamber was brought online. Sample Data: – Total Chlorine – amount of combined (reacted) and uncombined (unreacted) chlorine within the water. – Free Chlorine – amount of uncombined (unreacted) chlorine within the water.

PRE-CHAMBER USAGE DATA 4.0 Well #13R: Free/Total Cl2 Prior to Contact Chamber Online 3.5 3.0 2.5 2.0 1.5 Free Cl2 Total Cl2 1.0 Contact time less than 1 minute. 0.5 Reactions occurring within distribution system. Levels difficult to control, subject to distribution system fluctuations. 0.0 11/25 11/27 11/29 12/1 12/3 12/5 12/7 12/9 12/11 12/13

POST-CHAMBER USAGE DATA 4.0 Well #13R: Free/Total Cl2 After Contact Chamber Online 3.5 3.0 Free Cl2 Total Cl2 2.5 2.0 1.5 1.0 Contact time 5 minutes. Reactions occurring within contact chamber (stabilized). 0.5 Levels easier to control, no longer subject to distribution system fluctuations. Only residual (free) chlorine required to meet regulatory standards remaining. 0.0 12/15 12/17 12/19 12/21 12/23 12/25 12/27 12/29 12/31 1/2

MISSION ACCOMPLISHED! SAMPLE DATA CONFIRMS EXPECTED RESULTS ACHIEVED STABILIZED WATER CHEMISTRY ENTERING DISTRIBUTION SYSTEM PRIMARY REACTIONS COMPLETE

MOVING FORWARD All 13 contact chambers must be installed and placed online to realize maximum benefits. – 3 chambers have been installed – 2 chambers are online Anticipated that most of the chambers will be installed and online in FY 2008.
