Effluent charges for surface water generate CZK 300 million per year for the State Environmental Fund, while effluent charges for groundwater generate CZK 2 million for the municipalities. The rate of cost recovery is 100% when only operating costs are included, but drops to 10-20% when renewal and new investment costs are included. This is partly driven by the failure to account for the full depreciation of the infrastructure assets. Costs for WRM amount to 3-7% of the water bill.
