Protect critical well infrastructure with the only NSF/ANSI 61 certified impressed current system engineered specifically for water well cathodic protection.
The MATCOR ORCA System helps municipal and industrial operators prevent severe water well corrosion, extend asset life, and reduce costly emergency failures in corrosive groundwater environments.
Corrosive Water Wells Are Failing Faster Than Ever
In aggressive groundwater environments, water well corrosion rapidly damages internal steel infrastructure, leading to repeated maintenance events and costly emergency replacements.
Common Failure Points
- Casing and riser pipe damage
- Sand and debris intrusion
- Premature pump failures
- Regular emergency replacements
- Reactive infrastructure spending
Traditional approaches delay the problem instead of solving it. ORCA helps utilities move from reactive replacement to proactive asset preservation through engineered well casing cathodic protection.
ORCA: Engineered for Water Well Cathodic Protection
The ORCA (Oxidation Reduction for Casing and Accessories) System is a complete impressed current solution designed specifically for water well cathodic protection in municipal and industrial water systems.
Developed from MATCOR’s PF-Anode technology, ORCA helps prevent severe internal corrosion, protect critical infrastructure, and improve long-term well reliability in aggressive groundwater environments.
Each system includes an ORCA anode assembly, specialized junction box, and matched power supply rectifier.
Unlike traditional industrial anodes, ORCA is engineered specifically for potable water infrastructure and long-term water well casing cathodic protection.

Frequently Asked Questions
Everything you need to know about ORCA Water Well Anode System.
Is ORCA an NSF/ANSI 61 certified anode system?
Yes. ORCA is the only impressed current corrosion prevention system specifically engineered and NSF/ANSI 61 certified for drinking water well applications.
How does ORCA prevent electrical shorting inside tight well casings?
ORCA uses proprietary braided Kynar® technology designed to prevent the anode from contacting the casing or riser pipe in tight annular spaces.
Does ORCA require specialized cathodic protection installation crews?
No. ORCA is designed for contractor-friendly installation using standard well service contractors and existing well construction workflows.
Can ORCA be monitored after installation?
Yes. ORCA is an impressed current system that allows operators to take ongoing electrical readings and verify protection performance without pulling the pump or column pipe.
How long does ORCA protect water well infrastructure?
ORCA is engineered to extend water well asset life well beyond typical failure cycles which can be as short as 3 to 5 years in highly corrosive groundwater environments. The anode itself is designed for decades of service.
What makes ORCA different from traditional water well corrosion solutions?
Unlike permanent fillers or non-certified industrial anodes, ORCA is NSF/ANSI 61 certified, monitorable, replaceable, and specifically engineered for water well cathodic protection applications.
Is ORCA replacing the PF-Anode System for water well applications?
Yes. ORCA is MATCOR’s water well corrosion prevention solution and represents the evolution of the PF-Anode system for drinking water well applications. It was specifically engineered to meet the compliance, installation, and operational requirements of municipal and industrial water wells.
