Choosing the right water filtration system in Kununurra

A practical guide for off-mains or mains-fed homes

Why Water Filtration Matters in the Kimberley

Kununurra’s water sources and mineral content are unique, with high mineral loads (especially calcium and magnesium), occasional sediment, and the tropical climate affecting tank storage and water quality.

Off-mains homes rely on rainwater tanks, bores, or surface water, each with its own quirks. Even mains fed homes can experience mineral build-up and taste variations, making the right filtration system essential for both water quality and plumbing longevity.

Understanding Your Water Source

• Rainwater tanks: Great taste when maintained, but prone to bacteria, mosquito larvae, and leaf debris without filters or regular cleaning.

• Bore water: Often “hard” rich in minerals that can clog pipes, affect taste, and leave residue on taps and glassware.

• River/surface water: Needs thorough filtration and UV sterilisation to remove sediment and microbes.

  
  

Filtration Options for Kununurra Conditions

Type	What It Does	Best For	Cost Guide
Sediment Filters	Removes dirt, sand, and rust	Bore & surface water	$80–$200 setup
Carbon Filters	Improves taste, removes odour & chlorine	Rainwater or town supply	$150–$400
UV Sterilisers	Kills bacteria & viruses	All off-mains systems	$400–$800
Reverse Osmosis (RO)	Highest purification level	Bore water with high minerals	$600–$1,200+
Whole-House Systems	Filters all taps and showers	Family homes	$800–$2,000

💡 Local Tip: In Kununurra, sediment and bacterial control matter more than chlorine removal, especially if your water is fed from tanks or bores rather than chlorinated mains.

Maintenance & Challenges

• Regular Filter Changes: Every 6–12 months depending on use and sediment load.

• Tank Hygiene: Clean gutters, install leaf guards, and flush first flush diverters.

• Electricity & UV: UV systems need consistent power — consider a backup or surge protector during the wet season.

• Hard Water Scale: A pre-filter or softener can help protect pipes and appliances.
