WELL 11 TREATMENT PROJECT

Description

The Well 11 Treatment Project proposes to construct the following components: • Site demolition, clearing and grubbing on approximately 3.4 acres; • Construction of a perchlorate vessel foundation; • Placement of perchlorate treatment vessels with initial load of resin; • Installation of pretreatment cartridge filters; • Construction of nitrate system foundations; • Installation of a nitrate treatment system with tanks, resin, controls and softener; • Installation of on-site piping; • Placement of a brine holding tank; • Construction of polyethylene double-lined evaporation ponds; • Installation of associated electrical and controls; • Well pump upgrades; • Perimeter fencing; and • Drive path for ingress and egress of the Project site The proposed equipment is shown listed below. Construction Schedule: Construction of the Project is anticipated to be completed within six (6) months, which would include grading, site preparation, and construction of the water treatment infrastructure. Generally, construction would occur between the hours of 7:00 am and 5:00 pm, Monday through Friday, excluding holidays. Post-construction activities would include system testing, commissioning, and site clean-up. Construction would require temporary staging and storage of materials and equipment. Staging areas would be located on-site. Equipment: Construction equipment would likely include an excavator, backhoes, graders, skid steers, loaders, crane, and hauling trucks. Operation and Maintenance: Operation and maintenance of the water treatment facility would be performed by the existing City maintenance staff or contracted staff. Operation and maintenance associated with the evaporation pond alternative would consist of monitoring the ponds for leakage, occasional removal of crystalized salt from the bottom of the ponds, transferring the salt into super sacks and repair of the liner, as necessary. Brine deliveries to the Clean Harbors Buttonwillow facility would occur approximately every other day utilizing one (1) truck.
