Pool Engineering
ENGINEERING 312: Understanding Water Current

Learning Objectives

  • Review suction outlet details and flow rates.
  • Develop target areas to maximize water motion.
  • Discuss water current options.
  • Analyze horsepower requirements.


Whether working with a lazy river, wave pool or water park attractions, developing and working with water current can be a daunting task. Finding the proper amount of pressure, maximizing flow rates, utilizing safety grates all while maintaining water efficiency is vital in today’s growing market of commercial pool applications. This program will take you through the in-depth process and increase your understanding of water current.

Peter Davidson

Davidson started his testing with a plywood test tank in a carport in Malibu, Calif. and resulted in two test pattern pumping systems that were patented in the 1980’s and have become the forerunners of today’s Riverflow Pump System. Over the years, Davidson has developed various nozzles, manifolds, suction grates and sumps, designed to deliver optimum flow capacities safely. Davidson’s pursuit has been focused on highvolume rather than high-pressure as a means to provide appropriate current for a variety of applications. Current Systems, Inc. also pioneered the introduction of variable frequency drives in the swimming pool industry.
