Asbestos and pollutant surveys in the canton of Obwalden
For work in Obwalden, shared documents from Central Switzerland’s environmental services help organise the survey and waste dossier. The project’s municipality remains the contact for permit documents.
We work throughout Switzerland. State your preferred language for discussions and the report when enquiring.
Describe my projectDocuments to prepare for the permit application
The municipality of Sarnen describes waste documentation requirements applied throughout Obwalden since 2023: information on type, quantity and disposal where volumes are likely to exceed 200 m³ or hazardous substances are expected.
Two complementary Central Switzerland tools
The Umwelt Zentralschweiz portal publishes a building pollutant checklist and a disposal table. The first documents suspect elements; the second organises waste categories, quantities and destinations. They serve different needs when preparing the dossier.
Preparing your discussion with the municipality
- Gather conversion plans and information on material ages.
- Attach any checklist or table already completed by your representative.
- Specify additional documents requested by the municipality.
