Comments
Well was drilled as a test Well and following the pump test a decision to upgrade it and keep the well. It was determined that stainless steel rise was required rather than the carbon steel 12 inch that the well was drilled with so there was quite a lag in work following the pump test to completion of the well. the well was close to being complete with 12 inch steel and 12 inch telescoping screen they informed us that the well had to be comprised of all stainless steel – so we installed 10 inch
