Surface & Subsurface Drainage Systems

PPI Engineering designs surface drainage systems to convey storm water safely around and through vineyard areas to protected outlets.  PPI also designs systems that utilize subsurface drainage.  This involves a thorough analysis of the soil type and depth, water levels, topography and climate.  From this information, an effective subsurface drainage system can be designed to enhance the life and vigor of the grapevines.  PPI provides investigation, design, staking services, construction review and record drawing services for installation of our drainage systems.
