The Hidden Truth About Your Tank Water

For residents across the Northern Rivers—from the Byron Shire to Ballina, Lismore, Casino, Kyogle and beyond—tank water is life. But even with the best mesh and leaf-guards, your tank is a major collection point for more than just rain.

The unique damp, leafy conditions of our region mean your tank floor is likely hiding a layer of sludge, made up of:

Decayed Organic Matter:

Leaves, bird droppings, dust, and pollen that settle on your roof.

Sludge and Sediment:

A thick, stagnant layer that houses harmful bacteria and pathogens.

Pests and Debris:

Occasionally, deceased animals (like snakes or possums) can contaminate your entire supply, requiring immediate attention.

Mould and Biofilm:

Green or black slime that clings to the tank walls and introduces bad odours and tastes.

If you’ve noticed a change in the taste, smell, or colour of your water, or if you’ve had unexplained health issues, your water tank is asking for a professional clean. At Water Sorter, we make the process simple, safe, and stress-free.

Our Effective Water Tank Cleaning Services

Owner and operator Nathan is passionate about delivering clean, healthy water to Northern Rivers families and businesses. We use specialised, commercial grade equipment to provide an effective, deep clean for most sized tanks and materials.

Clean Tank, from Full to Nearly Empty – With Minimal Water Loss

The great news? The majority of water tanks can be cleaned while they are still full, using a non invasive vacuum system.

Tank Cleaning While Full: We access the tank (often via a manhole) and carefully vacuum out the accumulated sludge and sediment from the bottom, leaving your main water supply intact with minimal water loss.

Full Empty & Scrub (When Needed): If the contamination levels are extremely high, for instance, if the tank has never been cleaned, or if there is significant animal contamination,a full empty may be necessary. In these cases, our technicians will fully drain and physically scrub the interior walls and base.

Optional Water Hygiene & Bacterial Control

We offer an optional tank sanitisation treatment that we highly recommend if your tank has been contaminated.

This process involves applying a tank safe disinfectant to the remaining water or tank walls for bacterial control as part of a healthy, clean water management strategy. It’s the final step to ensuring your water is safe and potable.

Refilling, Sorted.

If your tank needed to be emptied for cleaning, we have long-standing working relationships with trusted local water carters throughout the Northern Rivers (including Water 4 You and Water Please).
