Sombreffe pitfall to avoid

Individual treatment and rainwater.

Sombreffe is largely outside the collective sewer zone. If your unit requires an individual treatment system (IAS), expect €4,000 to €8,000 at your expense, plus mandatory maintenance. Ask in writing for the applicable treatment zone and include the IAS in the sale price.
