An Initial assessment will be performed to evaluate the existing condition of the water well. Based on the Initial evaluations, rehabilitation options will be proposed. The entire well will have to pulled and the casing will have to be video Inspected. Common causes of reduced well capacity could be sanding, rupture of casing, mineral bul* up, heavy encrustation, screen damage, screen dogging or mechanical failures of the pump. Depending on the assessment, rehabilitation could include brushing and boiling casing, replacing ruptured casing, adding an elon- gated nozzle to bull to reduce sand flow, chemical treatment, remachine the pump and or rewind.
