Oklahoma Water Resources Board–listed well driller or pump installer based in Wichita, Kansas. License category is geotechnical — ask if they drill or service house wells. Last checked 2026-08-17.
Important: A roster match does not prove current availability, every service tag, or coverage for every address. Confirm those details with the company.
Gsi Engineering LLC appears here because the name and phone match a current Oklahoma Water Resources Board well driller or pump installer row. The roster mailing city is Wichita, Kansas. That is a starting point for a call about well work — not a rating, endorsement, or coverage map.
Ask whether they still take the exact job at your land, what they charge, and when they can come. A Wichita mailing city does not mean they cover every street in Wichita or nearby towns. If this page is missing a website, email, or street address, we did not have a roster fact for it and we do not invent those fields.
Ask whether they drill a new well, service a pump, or both at your land. License categories on the official finder are a starting point, not a booking.
Keep notes on the well, the pump, and any well-log number if you have one. Then compare this record with other companies on the directory before you schedule.
