Questions about funding

No, the increase in fees is proportionate because the additional costs of the measures in WWTP correspond to about 6% of the current total costs for wastewater disposal.

All central WWTPs in Switzerland have been paying an annual fee of CHF 9 per connected resident into a fund since 1 January 2016 (limited until 2040). This covers 75% of the initial investment for additional treatment stages. After the expansion, the WWTPs will have to bear higher operating costs and are therefore exempt from the fee. Generally, the additional operating costs are likely to be higher than the wastewater fee.
