Work out water reuse savings instantly with clear inputs, formula shown and shareable results.
Water reuse saves the cost of fresh water and often the cost of discharging effluent, less the cost of treating it to the required standard. The net saving per cubic metre is the difference between fresh water cost and reuse treatment cost — reuse only pays where that gap is positive and the reuse demand is genuine.
Reuse saving
Net saving = volume reused x (fresh water cost - reuse treatment cost)
Water reuse for any application involving human contact is subject to microbiological and chemical quality standards. Confirm the applicable reuse regulations and validation requirements.
Cooling tower make-up, boiler feed after further polishing, process washing, irrigation, toilet flushing and dust suppression. Each has a different quality requirement and therefore a different treatment cost.
Yes where effluent is charged volumetrically or where discharge capacity is constrained. It often turns a marginal reuse case into a clearly positive one.
