The demonstration was conducted under the project led by Dr. Wilfredo P. David, entitled: A Pilot On-Farm Strategy Demonstration in Cabuyao, Laguna, Philippines. It was conducted so that the farmers and local drillers could gain experience in the actual shallow tubewell (STW) drilling, design, installation and development in the 4 barangays of Cabuyao: Gulod, Marinig, Sala, and Mamatid.

The demonstration used the DA-UPLB Drilling Rig Model II as its drilling equipment. Well development of the STWs was demonstrated up to the pumping of intermediate discharges, leaving the pumping at high discharges to the farmers.

A  well  point system  was  done  to  the  two  newly  constructed  wells  in  the  Gulod  sites  as  well as the rehabilitated and newly constructed wells in the Marinig site increasing their discharge from 4 lps to 6 lps and 8 lps respectively. The Sala and Mamatid sites, on the other hand, obtained discharges of about 15 lps and 12 lps from their respective wells.

The farmers and local drillers gained experience on the proper drilling, design, installation, and development of STW. The Gulod site provided most of the procedural and troubleshooting techniques which were later analyzed and applied in the succeeding sites of Marinig, Sala, and Mamatid.
