Madison Farms is located in the heart of the Butter Creek critical ground water area in Oregon state.  The farm was in need of an ASR down hole control valve and that is what lead to the design and manufacture of the very first 3R Valve.  I built a 6 inch valve with 750 GPM of recharge capacity and 500 GPM of recovery.
