Metered tariffs for domestic customers in the lowest category of rateable property value are set at 61 Guyanese dollar per cubic meter (US$0.32/m3) outside Georgetown and 63 Guyanese dollar per cubic meter (US$0.33/m3) in Georgetown. At a consumption of 20 cubic meter per month (133 liter/capita/day for a family of five) that tariff would be equivalent to an increase of the water bill of 64% for customers outside Georgetown and 28% for customers in Georgetown compared to the currently prevailing flat rate for unmetered customers.
