The City completed the condition evaluation and assessment of its eight reservoirs in December 2013.  A list of recommended repairs and rehabilitation for each reservoir was established.  Following the condition evaluation and assessment, the design of the repair and rehabilitation for Magnolia Reservoir was completed in 2017.    

The Magnolia Reservoir and Booster Pump Station Rehabilitation Project consists of the repair work for the buried pre-stressed concrete reservoir and the booster pump station located at Magnolia Park.  The extent of the work is as follows: The reservoir repairs consist of crack, spall, and joint repair, construction of seismic curb, roof waterproofing, rust spot repair, and the addition of a fall protection system. Site Improvements include rerouting the existing sub-drain sump pump piping, replacement of the sump hatch and sump vault lid and hatch, repair of the overflow flap gate, construction of a new parking lot and ADA ramp, installation of bollards and a mow strip around the reservoir, and replacement of the meter vault and piping. The repair work for the pump station consists of replacement of the existing engine and booster pump, replacement of the existing exhaust system, replacement of the existing catalytic converter, replacement of two 10-inch butterfly valves, replacement of the 10-inch check valve, refurbishment of the existing flow control valve, and replacement of the roof and existing removable dormer.
