What Is Bypass Pumping?
Temporary bypass pumping moves wastewater around unavailable station equipment or a damaged section of the collection system. It may be used during planned work or an emergency.
A bypass normally draws wastewater from an approved upstream point and discharges it into an approved downstream point or force-main connection. The path must remain contained.
Planning considers expected flow, changing peak flow, suction conditions, discharge pressure, pipe routing, backup capacity, fuel or power, monitoring, and public protection. At sea level, air pressure can push water up a suction line no more than about 34 feet, so practical suction lift for a bypass pump is typically about 25 feet or less. Engineering review may be required.
Bypass pumping does not suspend permit or reporting duties. Follow the approved bypass plan, plant procedures, and directions from your permit or your state or provincial regulator.
Key point: A bypass is a temporary conveyance system that must safely carry the full expected duty assigned to it.
