Keep Water Flowing While the Tank Is Out of Service
When an elevated tank must come out of service for cleaning, inspection or a new coating, Mercer Controls provides temporary bypass solutions that keep your system operational. We design and install temporary pumping and control configurations so you can complete repairs or maintenance without interrupting treatment or distribution.
Our approach allows pumps to operate based on pressure control using variable frequency drives (VFDs) rather than tank levels or normal process controls — a capability that is rare and highly specialized.
Custom Bypass Solutions,
Start to Finish
Mercer Controls handles the entire bypass process:
- Take an elevated tank offline for cleaning, inspection or a new interior or exterior coating without interrupting service
- Configure and install VFDs for pressure-based pump control — so the system holds pressure with the tank out of service
- Design temporary control logic, alarms and safeguards for the bypass period
- Install temporary piping, hoses and connections as needed
- Set up, test and verify operation before the tank comes down
- Monitor and adjust performance for the duration of the bypass
We ensure the system is stable and reliable before turning it over.

Flexible Rental Support
Bypass systems are provided on a rental basis, ranging from short-term needs (as little as seven days) to extended projects lasting weeks or months. Our team installs, maintains, and supports the system for the duration of the project.
This allows operators to focus on repairs and maintenance while knowing the system will continue to operate safely.
Operational Continuity,
No Compromises
Temporary bypassing is about one thing: keeping water moving and treatment running while critical work is completed. Mercer Controls delivers solutions that protect operations, maintain service, and reduce risk during complex projects.
