Our Services

Water Treatment

At Sue Kelly Water Treatment, we bring over three decades of experience and expertise to ensure the purity and safety of your water. 

Filters & Purifiers

Water filters and purifiers are the unsung heroes of modern living, quietly ensuring that the water we consume is clean, safe, and refreshing.


We provide valuable insights and information about the presence of nitrates in water sources and how to address this potential concern for clean and safe drinking water.

Fluoride & Asbestos

Fluoride and asbestos are two potential contaminants that can be found in water supplies, with fluoride often added for dental health benefits and asbestos posing health risks due to its presence in older pipes or infrastructure.

Can you benefit from some of these solutions we offer?

Dear Sue

I hope this note finds you and your family in good health. I just want you to know how much I appreciate everything you did. I’m no expert working with people, but I did at one stage of my life for 10 years. It was definitely long enough to understand that a smile, a thank you and a helping hand can make a huge difference.

Your compassion, patience, kindness and willingness to help out was incredible and ultimately the reason your company is light years ahead of the rest.

I can tell you one thing: I would never been able to complete this project without you. You went out of your way to reply to emails, when nobody else would give me the light of the day.

I remember saying we were on a budget, therefore I needed to install the system myself and you made that possible. I have so much respect for you!

Just know, from the bottom of my heart how proud and grateful I was that I found your company.

You are always welcome around our campfire anytime.

Yours sincerely
