Biodigesters are different from regular septic tanks in a few ways. If you are shopping around for the best wastewater treatment solution, it’s important to consider the long-term benefits of a biodigester.


Biodigesters are affordable


Installing a biodigester septic tank is cheaper than installing a standard septic tank because less excavation is required. The tank is smaller and the layout simpler, so less digging is needed. In some cases, you can even install a biodigester above ground, provided there is sufficient slope.

You save money on future costs, since pumping is not required. This is especially nice for remote locations or island living where getting a septic tank pumped can be a real hassle.

Biodigester tanks might cost more than septic tanks, but the overall cost of the unit and installation is much lower.


Biodigesters are good for the environment


Biodigesters are more efficient than traditional septic systems when it comes to treating waste. With a biodigester, the solids become a potent garden fertilizer, the liquids add nitrogen to the soil, and the overall system is less smelly than a septic system.


Biodigesters are low maintenance


Unlike septic systems, biodigesters do not require maintenance or pumping.

For our Easy-Clean Biodigesters, just turn a faucet once a year to empty the primary tank into a secondary drying tank. When the material being drained starts to change colour, close the faucet again. The material in the secondary tank only needs two months to dry before it becomes inert phosphorus that can be composted or mixed with lime and added to the garden.

No access to municipal water, power, sewer, or pumps? No problem.


Anaerobic digestion


CITIJAL Easy-Clean Biodigesters use anaerobic digestion to treat organic household waste and turn it into high-phosphorus, garden-ready fertilizer.

They are the ideal septic system solution for remote homes, campsites, resorts, or other locations where city sewer systems are not accessible.

They do not require a large septic field or regular pumping.

Household waste enters the Biodigester where it is separated into liquids and solids. Liquids pass through a series of filters before being released into a drainage field. Solids are broken down by bacteria through anaerobic biodigestion, transforming them into harmless phosphorus which is deposited into a secondary tank.


The system can then be easily emptied and the high-phosphorus content extracted by simply opening a faucet.


Compost it!


Once you empty the tank, mix the resulting materials with common garden lime to create a potent natural fertilizer!
