Meters are read twice a year in June and December, with bills being forwarded the following month (January and July) and due March 1st and August 31st.
Metered Water Rates are based on a fixed rate (dependent on size of meter) plus consumption of cubic meters (m3).
Metered Sewer Rates are based on 80% of water consumption. There is a minimum charge per billing department, and a consumption charge for consumption above the minimum.
If you are required to be connected to the sewer, and have not done so as yet, a non-compliant fee is charged.
