How Can Closed Pipe Flow Measurement Reduce The Risk Of Sewer System Surcharging?

Source: KROHNE, Inc.

All sewer systems have a finite capacity of wastewater they can transport. This capacity can be pushed beyond its limit when inflow and infiltration occur. Combined sewer systems (CSS) are particularly vulnerable to surcharging, especially during wet weather events. However, separated sewer systems can also experience surcharging if not properly managed. Regardless of the type of sewer system, surcharging can have severe consequences, including overflows, basement flooding, and pollution of water bodies. In addition to the health and environmental impact, surcharging can also result in upset customers, compliance failures, and government intervention.

Flow measurement devices are frequently used throughout the system to track the amount of water in the pipes to ensure the system isn’t suddenly overwhelmed. There are myriad flow technologies, including multiple types of both open and closed pipe devices. While each has its benefits and uses, electromagnetic flow meters (mag meters) stand out as the most consistent, accurate, and reliable. One specific type of magmeter is uniquely adapted to this application. KROHNE’s TIDALFLUX can handle the normally less than full sewer pipes since it is a combination instrument featuring a capacitive level system within a flow meter. That combination allows the meter to operate like a regular magflow meter even with the fluid level within the pipe being as low as 10% of the pipe’s diameter.   This webinar will explore how these mag meters compare to common types of open pipe measurement technologies and how they can help minimize or prevent surcharging.
