We do not claim an NEA tank-cleaner licence
Older copy on this URL sounded like “NEA + PUB licensed tank specialist”. That is wrong. Alpha & Omega Trinity is a PUB licensed plumber (WS16882018) on aotrinitysg.com. Tank cleaning on aot-tank.com is isolate, desludge, wash, disinfect, flush — plus photos for MCST.
What you still get
- Rooftop / basement / GRP / PE / stainless cleaning
- Photo notes of covers, overflow and insect screens
- Optional water sample tests quoted separately
Full company licences: aot.sg/licences. Cleaning scope: water tank cleaning.
