Document Description
The City of Santa Cruz Water Department (City) will rehabilitate its Beltz Well 10 and Tait Wells 1B, 3B, and 4 by chemical and mechanical means to restore lost well performance. Beltz 10 was never fully and properly developed after well construction due to limitations that existed at that time for the disposal of well development water. That situation has since been resolved and the City now seeks to maximize the production capacity of the well through a rigorous well rehabilitation/well development program.
Generally, the work shall consist of:
• Removal of existing pump assembly
• Inspection and assessment of pumping equipment
• Pre-rehabilitation video surveying
• Nylon brushing the well screen
• Cleaning of the well screen by hydraulic pressure jetting
• Bailing the well to bottom
• Installation of tanks, piping, and treatment system for discharge water
• Installation of a 4-inch PVC pipeline at the Beltz WTP from the raw water
• pipeline to the storm drain inlet
• Pre-chemical development by airlift/swabbing with dual swab
• Chemical treatment
• Agitation by swabbing
• Post-chemical development by airlift/swabbing with dual swab
• Post-rehabilitation video surveying
• Well disinfection
• Reinstallation of City’s pump assembly
