The SepticJohn by ECOJOHN is a revolutionary off grid septic system that provides a clean, efficient, and low-maintenance solution for handling human waste and grey water. Unlike a traditional septic system, which relies on leach lines and a drain field to process waste, the SepticJohn system incinerates waste using a highly efficient burner, leaving behind only sterile ash. This makes it ideal for off grid homes, cabins, and remote locations where installing septic tanks or connecting to a grid septic system is impractical or impossible.
The SepticJohn system is engineered with high-quality materials to withstand high usage and severe environments. Its efficient low flush toilets and submersible transfer pump work together to reduce water usage while ensuring that the system processes waste effectively. The entire system has been rigorously tested by multiple global testing agencies to ensure safety, quality, and compliance with local regulations.
The SepticJohn is more than just an off grid septic system — it’s an incinerating septic alternative that burns waste at high temperatures, reducing it to sterile ash. This eliminates the need for a leach field or drain field, making it a game-changer for off grid wastewater management.
SepticJohn incinerators provide an innovative solution for wastewater treatment systems. Unlike traditional septic systems that depend on large leach fields, mound systems, or aerobic systems, SepticJohn systems efficiently convert all black and grey water into a small amount of sterile ash. With these features in mind, it makes the SepticJohn perfect for:
SepticJohn offers a modern, eco-friendly alternative to traditional septic systems by incinerating all wastewater into sterile ash, eliminating the need for leach fields and complex treatment systems. Its compact design makes it ideal for off-grid homes, remote locations, and small lots. The system is easy to install, requires minimal maintenance, and reduces environmental impact by preventing groundwater contamination. SepticJohn delivers a reliable, efficient, and long-lasting wastewater solution.
SepticJohn eliminates these issues by completely incinerating wastewater into sterile ash.
Selecting the right SepticJohn model depends on your household size, wastewater output, and installation requirements. SepticJohn offers different models designed for various residential and commercial needs. Larger models handle higher capacity, while smaller units are ideal for compact spaces and lower usage. Proper sizing ensures efficient operation and longevity.

Unlike traditional septic systems that use leach fields and aerobic systems, the SepticJohn incinerates waste, leaving only sterile ash.
Yes, it’s ideal for off grid homes and remote locations without access to grid septic systems.
The sterile ash should be removed periodically depending on usage levels.
Yes, it’s compatible with standard low flush toilets, washing machines, and shower heads.
Yes, the system operates with low emissions and efficient burners to reduce environmental impact.
SepticJohn (also known as ECOJOHN WC series) is a whole-house incinerating septic system. All wastewater—from toilets, showers, sinks, etc.—flows into a holding tank. When the tank fills, a pump feeds batches into a heated combustion chamber, where high temperatures incinerate the waste down to sterile ash. It's automated via PLC controls and sensors, runs with low emissions, and removes waste volume entirely.
There are four models to fit different household sizes:
Each runs on propane, natural gas, diesel (also kerosene, JP8), and is powered by 12 V DC, 120 VAC, or 240 VAC.
Connect your existing toilets and gray water fixtures to a standard holding tank sized per local codes (e.g., Indiana requires ~150 gal/bedroom). A submersible pump sends waste into the SepticJohn unit, which must be placed in a separate structure or enclosure. You’ll also need fuel hookups, electrical power, and a vent/exhaust stack. Installation must follow manufacturer specs and local codes.
Fuel use by model:
Power draw is minimal—4 A @ 120 VAC, 2 A @ 240 VAC, or ~20 A @ 12 V DC.
Base prices (for WC5 model) start around $10,995, with larger models ranging up to ~$26,995 for WC64 depending on power/fuel options.
Running costs depend on fuel usage; while heavier use consumes more gas, most off‑grid setups stay in a reasonable range (no septic pumping or field repairs). Exact costs will depend on local fuel prices and usage patterns.
Yes. The WC series is NSF‑P157 certified, UL/CSA approved, durable, and uses PLC control with safety monitoring. It’s been tested by U.S. military and designed for rugged environments.
For instance, Texas TCEQ and Indiana Health have approved use in one/two-family homes with correct tank sizing and permitting. Note: air permits and ash disposal must follow local regs.
