DESCRIPTION A. Background The UV disinfection system expansion project at the Wastewater Resource Recovery Facility is almost complete. During the expansion it was determined that a critical design error was made on the elevation of the Parshall flume that caused inaccurate effluent flow measurement. A temporary fix was put in place while a plan was devised to correct the error. The redesign is finished and ready to be implemented to complete the project. B. Proposed Project To allow for accurate measurement of the effluent flow and to stay in compliance with the City's NPDES permit, the following changes are critical: • The UV disinfection system flume will be expanded and a new flume insert installed. • The pipe upstream of the flume will be re-layed at a lower slope percentage. Page I of 2 C. Describe Item This deductive change order will cover the construction costs of the additional flume and pipe. CH2M, the original design engineering company, is providing all engineering support services related to this portion of the project at no cost to the City. III. IMPACT A.
