The latest report on the state of Tasmania's water and sewerage has confirmed the need for urgent action.

The report shows that:

  • In 2015-16, the number of sewer overflows increased by more than 20 per cent from 164 to 201; 
  • The rate of sewer overflows in Tasmania (4.3 per 100 km of sewer main) is up to eight times that of similar sized utilities on the mainland (0.5-1 per 100 km of sewer main);
  • The total number of sewer main breaks and chokes also increased from 57 to 61 per 100 km of sewer main, which is almost double the rate reported nationally for similar size utilities at 32 breaks and chokes per 100 kms of sewer main;
  • Only 1 of 79 sewage treatment plants achieved full compliance with discharge limits;
  • In 2015‐16, TasWater received 2,892 complaints, up 24 per cent from 2,324 for the previous year. The largest group of complaints were in relation to water quality (38 per cent);
  • Thirteen water supplies had chemical contaminants detected above safe health limits;
  • Twenty five systems were operated under a temporary or permanent boil water alert while another five systems had a public health alert (do not consume) in place; and
