 In 2008 an Extraordinary Tariff Adjustment was granted to all WSPs as an interim measure to assist WSPs to meet their operation and maintenance costs.Tariffs for sewerage services are part of tariff adjustments and the aim is to reach full cost recovery also for sanitation.The ministry responsible for water is, however, aware that full cost recovery tariffs for sewerage for certain systems would make the service provision unaffordable for many connected households.
