What's this project all about?

TasWater is upgrading Tasmania's sewer network to ensure it stays reliable for years to come. Through a statewide project, we're cleaning, inspecting, and relining sections of aging sewer infrastructure to keep wastewater flowing safely and efficiently.

There are a few steps involved in rehabilitating the sewer.

• Initial inspections - We will locate the sewer manholes and check their condition. Our crew will use low pressure jetting to clean the sewer pipes, then inspect them using CCTV to understand their condition.
• Civil works where repairs are needed - If the sewer pipe or manhole is in poor condition, or if there are blockages, excavation may be needed to prevent sewage overflows.
• Sewer relining and final inspections - The sewer pipes will then be repaired by installing a structural liner inside the existing pipe. We will reopen the house connection branches by carefully cutting the liner using robotic equipment. After this, we will carry out another CCTV inspection to make sure the liner has been installed correctly.

A typical pipeline rehabilitation takes around four days to complete, depending on the condition of the sewer. Each stage of the process will take place on different days and at different times.

If we need to carry out work within your property, we will talk with you beforehand and explain what is involved before any work begins.

Why do Relining?

Sewer relining is a smarter, more efficient way to renew aging pipes. Instead of digging up and replacing old sewer lines, we install a new, durable lining inside the existing pipes, reinforcing them from within. This method is:

• Less disruptive - No interruptions to your sewer service
• Cost-effective - A long-lasting solution without major replacement costs
• Faster - Avoids weeks of digging and road closures
• Minimal impact - Reduces noise, mess, and inconvenience to the community.

What to expect during these works

Our contractor, UE Spectran JV, will take steps to minimise any inconvenience. However, you may notice some temporary impacts while we carry out the works, including:

• Work crews and vehicles - Construction teams and equipment moving in and out of the area
• Some noise - Generators, pump trucks, and machinery in operation
• A temporary odour - A harmless smell from the sewer lining process that will dissipate quickly
• Traffic and pedestrian changes - Temporary signage and traffic management where needed to keep everyone safe. There may also be restricted access to footpaths, roads and parking

We apologise for any inconvenience this may cause, and we appreciate your patience and understanding as we complete this important work.

Tip to Reduce Odours

To help prevent any temporary odours from entering your home, simply pour a small amount of water down all sinks, drains, and floor waste outlets before and at regular intervals during the work. This helps maintain the water seal in your pipes.

Protecting Our Sewer System Starts With you

What goes down the drain matters! Pouring fats, oils, and chemicals down sinks can clog pipes, damage the sewer system, and make wastewater harder to treat, and ultimately impacting Tasmania's environment.

By being mindful of what you dispose of, you're helping to keep our sewer network flowing safely and efficiently for everyone.
