Why Choose Katchment Kleaners?


 
Clean Your Tank
We’ll brush and sanitize the sidewalls, skim off floating debris, and vacuum sediment from the bottom of your catchment tank — leaving your system clean to collect fresh rainwater.
Inspect Your System
We check for leaks in your pressure tank bladder, inspect the pump, and adjust air pressure as needed — ensuring your rainwater system runs efficiently and reliably.
Condition The Water
We add oxidizer to reduce organic buildup and use mineral stabilizers to help neutralize acidic rainwater — protecting your plumbing and making your water safer.
Are You Off-Grid?
No power? No problem. For off-grid homes or outages, we can bring our own generator and power your catchment cleaning service without tapping into your supply.
Ohana Special Savings
Friends, family, or neighbors within 5 miles who book a same-day cleaning each get $25 off. Clean together, save together — it’s the neighborly way.
Replace Old Stuff
We’ll replace worn parts like stainless steel clamps, strainer bags, and — using your stock — filter cartridges, at no extra charge as part of your service.
