Perwez pitfall to avoid

Sewer network and individual treatment.

Several villages in the municipality (Malèves, Thorembais-les-Béguines) are not in a collective sewer zone. Check whether your unit depends on an individual treatment system (IAS) — it will be at your expense (€4,000 to €8,000) and maintenance is mandatory. The developer must state this in the deed of sale.

Témoignage acheteur
« The developer had not mentioned the IAS in the initial quote. Luckily the check let us renegotiate. »
