Stormwater fee: check sealed area and notice

Many municipalities levy a separate stormwater fee based on the sealed area connected to the sewer. If the assumed area is wrong, for example because areas infiltrate or are not connected at all, you pay too much. Reviewing the notice is worthwhile.

Your chances of getting your money back

The stormwater fee is measured by the sealed area connected to the sewer (municipal fee statute). Unconnected or infiltrating areas may not be counted in full.

If the assumed area is too large or infiltrating areas (e.g. with infiltration, cistern, green roof) are not taken into account, you can dispute the notice. De-sealing measures can lower the fee.

What you should do now

1
1. Check the areas
Compare the sealed area assumed in the notice with the areas actually connected.
2
2. Account for infiltration
Areas with infiltration, cistern or green roof may often be counted at a reduced rate, report them.
3
3. File an objection
If the area is wrong, file an objection against the fee notice within the deadline.
4
4. Consider de-sealing
Through de-sealing or rainwater use you can reduce the countable area and thus the fee.

How to spot the scam

The assumed sealed area is larger than the one actually connected.
Infiltrating areas or a cistern are not taken into account.
The notice is based on outdated area data.

Frequently asked questions

What is the stormwater fee based on?

On the sealed area of your property connected to the public sewer, set out in the municipal fee statute. The more area connected, the higher the fee. Unconnected areas may not be counted in full.

How can I lower the fee?

By reporting infiltrating areas, a cistern or a green roof, which are often counted at a reduced rate, or through actual de-sealing. You can also have an incorrectly oversized area corrected.

How do I fight the notice?

Compare the assumed area with the one actually connected and, in case of deviations, file an objection against the fee notice within the deadline. Attach evidence of infiltration or reduced areas.
