Estimate your trade-effluent bill.

Your trade-effluent charge is set by the Mogden formula, the public method your water company uses. Enter your figures to see an indicative annual bill and how much of it is driven by strength, the part you can bring down. Nothing is shared until you choose to.

Your figures
Your discharge
Your effluent strength (after settlement)
Charging rates

These are illustrative values. Your water company publishes the exact rate bands and standard strengths in its annual trade-effluent charging scheme. Enter those for an accurate figure.

Indicative annual bill
~£352,000
On about 132,000 m3 a year, at ~2.66 GBP per m3
76%Driven by strength (reducible)~£266,000 a year
24%Driven by volume and conveyance~£86,000 a year

This is an indicative estimate from the figures you enter, not a quote. Rate bands and standard strengths vary by water company and change each year. Your actual charge, and what could be reduced, is confirmed per site.

How this is worked out

The Mogden formula sets a charge per cubic metre: C = R + V + B(Ot/Os) + S(St/Ss). R and V cover reception, conveyance and volume. The B and S terms scale with your effluent's strength (COD and suspended solids) against standard settled sewage. Bring the strength down and the B and S terms fall with it. Your annual bill is that charge multiplied by your yearly volume.
