70 per cent of people who have to pay the sewerage charge could pay less than £100 under new proposals.
Plans are underway to scrap the so called "toilet tax" and replace it with a charge linked to a property's rateable value.
Chairman of the Manx Utilities Authority Alf Cannan says the flat rate fee wasn't fair:
The rate would be set at 62 pence in the pound - meaning properties with a higher rate value would pay more.
Mr Cannan says it's not perfect but should make things more equitable:
