However, we discovered we are not meeting our original objectives. Here <br />is the explanation I sent to MWMC for that supplemental budget request. <br /> <br />Aeration Blower Reappropriation Request <br /> <br />The unspent funds of $843,881 for the Aeration Blower Replacement project are being requested for re- <br />appropriation to accomplish the project’s energy reduction objectives. The blower installation was <br />completed in time to receive funding from EWEB and we are currently studying the blower operation <br />with respect to demand response savings potential. Additionally, the treatment process is currently <br />achieving energy savings from the installation of the energy efficient blower as originally planned. <br />However, the energy savings are not to the extent as expected. <br /> <br />Upon review of the calculations used in design, an error in historical process data was discovered. This <br />has prompted a study of what additional aeration capacity, if any, is needed. Once this incremental <br />amount is quantified, we will evaluate if there will be a positive return on investment to fill the gap with a <br />second energy efficient blower. The amount requested reflects the cost of a second blower similar to <br />what has been installed. The addition of a second blower is one option and we will also explore other <br />options that may achieve the energy savings objectives at a lower cost. Appropriation of the funds at this <br />time will also allow potential future project work to continue without interruption. <br /> <br />Thanks, <br />John <br /> <br /> <br />_____________________________________________ <br />From: WEIXELMAN Susan E <br />Sent: Thursday, October 31, 2013 10:34 AM <br />To: HUBERD John C <br />Subject: Minor follow up from SB meeting with Kurt <br /> <br /> <br />1 <br /> <br />
