Liquid Waste

Liquid waste can be part of a potential IRM system.

Historically liquid waste management has been managed as a cost needed to prevent health and contamination issues. However liquid waste can be processed to capture treated water and both energy and nutrients. This reduces the costs for treatment and improves environmental results.


A study for three communities recommended a system at $345m project cost. We reviewed the recommended system and found the cost had been underestimated, and would actually be in the range of $1.1bn.

The recommended IRM system is projected to be at least $1.14bn better financially, recycling 10% of the community’s water and potentially eliminating liquid waste treatment costs, with superior ecological and environmental results. If further optimized, the project should be capable of being $1.4-1.5bn better.

The analysis and recommendations were subjected to more than 62 expert multidisciplinary reviews and recommended for implementation, a variant of which is now being pursued.
