1.0 PROJECT DESCRIPTION would be housed above grade in a structure architecturally similar to the other pump stations and facilities at the Monarch Bay Golf Complex. Prior to construction, the City would remove up to six ornamental trees within the golf complex grounds. The water recycling plant would be developed initially to serve the Monarch Bay Golf Complex (Phase la); additional treatment processes subsequently would be added for Phases lb and 3. The proposed Phase la sodium hypochlorite disinfection facility would have a design capacity of up to 1,100 gallons per minute (gpm) (1.6 mgd) in order to provide additional disinfection for the disinfected secondary-23 recycled water to use at the Monarch Bay Golf Complex. Water treatment chemicals stored on site would include liquid sodium hypochlorite. The facility would have secondary containment where water treatment chemicals are stored. When filtration and disinfection necessary for disinfected tertiary for Phase lb is required, a filtration plant and ultraviolet (W) disinfection system with a total capacity of up to 800 gpm or 1.15 mgd is expected to be sufficient to meet the needs of the Phase 1 b and Phase 3 (planned} use areas. Following filtration and W disinfection, the disinfected tertiary recycled water will be delivered via an 800 gpm pump station and approximately 1,000 linear feet of 18-inch (maximum) diameter pipeline to Marina Park/Par Course and nearby roadway medians. RECYCLED WATER STORAGE IN EXISTING GOLF COMPLEX LAKES AND AT THE WPCP Irrigation at the golf complex and Marina Park occurs during nighttime/early morning hours on all but the hottest days of the year-, necessitating storage of the recycled water during non- irrigation (daytime) hours. Currently, the par course is not irrigated. Disinfected-23 recycled water would be pumped to the existing lakes at the golf complex for temporary storage prior to irrigation. Storage for other recycled water would occur at the WPCP in existing tanks. The recycled water would then be pumped at the rate required for use at Marina Park/Par Course and roadway medians from approximately 10:00 p.m. to 5:00 a.m. and filtered and disinfected prior to application. PROPOSED PIPELINE TO MARINA PARK/PAR COURSE AND ROADWAY MEDIANS Marina Park at Monarch Bay Drive and Fairway Drive, is a 30-acre regional park bordering the San Leandro shoreline. Amenities include picnic areas, play apparatus, grassy area, and the mile- long par course. Marina Park is across Monarch Bay Drive and to the south of the water recycling plant site. For delivery of recycled water to the Marina Park/Par Course and nearby roadway medians, the Ciry would install a 1,500 foot long, up to 18-inch diameter pipeline. Table 1-2 presents characteristics of this (and other) .pipelines proposed as part of the Project. From the water recycling plant, the proposed pipeline would cross Monarch Bay Drive via bore and jack construction to a boat ramp parking lot. The alignment traverses the parking lot southward to Marina Park. San Leandro Recycled Water Project 1-8 ESA / 7A3193 Daft IS/MINI)
