TASWATER has increased water and sewerage prices for 2014-15, in line with those approved by the state's economic regulator in 2012.
Water supply for a typical residential property with 20-millimetre connection will cost $322, while the sewerage cost has been set at $536 for the 12 months.
Fully treated, potable water usage per 1000 litres will cost 94.
Costs have risen marginally over the three-year price and services plan period.
The economic regulator's charges are part of the continuing process for the state's three former water bodies to come under one cost structure, to better ensure people pay for the services they receive.
TasWater acting chief executive Dean Page said that a household bill was dependent on the region in which customers lived, service type, size and number of connections to the property and what was currently being paid.
Where the current charge is below the target price for the region, it will increase by a maximum of $50 per service or 10 per cent - whichever is greater.
If the current charge meets target pricing for the region, it will increase by 6 per cent per service and if it is above the target price, it will decrease by 5 per cent.
Mr Page said the majority of customers were still not at target pricing.
For the three-year regulatory period, Ben Lomond customers with a typical connection have seen their water rates increase by $36, from $286 in 2012-13 to $322 in 2014-15.
Sewerage rates have risen from $477 in 2012-13 to $536 this year and potable water rose from 90 to 94 over the same period.
Consultation on the draft paper governing the next three-year period of pricing to 2018 closed last week.
