Document Description
The NPDES Permit for the City's Wastewater Treatment Plant (WWTP) requires installation of an effluent flow meter to accurately measure flows from the WWTP to the discharge point into an unnamed seasonal drainage (approximately 6 feet wide) which flows to Laguna Creek. Currently, two outfalls discharge water from the storage reservoir into the unnamed seasonal drainage channel. One of the outfalls delivers water from the cascade aerator and the other outfall is a drain directly from the storage reservoir when water levels fall below the level of the cascade aerator. An 8-foot separation exists between the two structures. In order to accurately meter the flow from both outfalls, the two pipelines need to be connected at a "T" within a new catch basin structure and a 16" diameter pipeline needs to be extended about 31 feet into the unnamed channel to reduce turbulence at the meter point. The flow meter would be installed about 6' downstream and an elevation head would be constructed on the far side of the flow meter in order to keep the meter constantly full to provide accurate measurements. The pipeline would then extend another 30 feet to its point of final discharge. The project will require filling 0.007 acre of the existing seasonal drainage for the new outfall structure and pipeline base.
