Trakhees Approved Water Tank Cleaning
If your company operates in JAFZA, Technopark or another PCFC-controlled free zone, a water tank cleaning certificate from a Trakhees-approved contractor is part of staying compliant — and for many establishments it’s now a step on the path to renewing the trade licence. Dotless Cleaning Services holds PCFC Certificate of Approval No. 2727 from Trakhees EHSS, so the clean we carry out and the certificate we issue are accepted within free-zone jurisdiction. This page explains the requirement, what we do, and how we get you the document you need.
Why Free-Zone Companies Need a Water Tank Cleaning Certificate
Companies inside Jebel Ali Free Zone, Technopark and other PCFC-controlled zones sit under Trakhees — the regulatory arm of the Ports, Customs & Free Zone Corporation — for environment, health and safety. As part of that EHSS compliance, free-zone establishments are expected to keep their water storage clean and safe, and to show it: a water tank cleaning certificate from an approved contractor. For many companies this now sits directly on the renewal path — without the certificate, the trade licence renewal stalls.
Here’s the catch most companies hit: a water tank cleaner approved only by Dubai Municipality is not automatically accepted inside PCFC jurisdiction. Trakhees wants a contractor approved under its system. That’s where most providers fall short — and where Dotless is already cleared.
Dotless is Trakhees / PCFC Approved
Dotless Cleaning Services L.L.C holds PCFC Certificate of Approval No. 2727, issued by the Environment, Health, Safety & Sustainability Department (EHSS) of Trakhees, Ports, Customs & Free Zone Corporation, authorising water tank cleaning services within PCFC jurisdiction (effective 5 August 2026, valid until 4 August 2027). We also hold Dubai Municipality DM-FSD Operator’s Permit Sr. No. 00292 and are DM-certified.
That dual standing — Trakhees and Dubai Municipality — means we can serve both your free-zone premises and any mainland sites under a single contractor, and the certificate we issue is recognised where you need it.

What The Service Includes

● High-pressure jet cleaning and removal of all wastewater and residue.
● Application of an approved disinfectant / chlorine solution with the required contact time.

Case Study: A JAFZA Company That Renewed On Time
A JAFZA-based engineering services company needed its water tanks cleaned and disinfected as part of its licence renewal. Dotless carried out the full clean and disinfection at the JAFZA site and issued the completion certificate. With that document in hand, the company was able to complete its trade licence renewal. One scheduled visit, one certificate, requirement closed — which is exactly how a renewal task should go when the contractor is already approved.
The Certificate You Receive
The deliverable isn’t just a clean tank — it’s the paperwork. You receive a Dotless completion certificate recording the premises, the scope of work and the service carried out, on our letterhead and under our Trakhees and DM credentials. It’s the document your PRO or admin team submits as part of the renewal file.

Frequently Asked Questions
Is water tank cleaning required to renew a JAFZA or Technopark trade licence?
For many free-zone establishments, a water tank cleaning certificate from a Trakhees-approved contractor is part of the EHSS compliance that feeds the renewal. Check your renewal requirements — and if it’s needed, Dotless is approved to do it.
Why can’t I just use a Dubai Municipality-approved cleaner?
Inside PCFC-controlled free zones, Trakhees wants a contractor approved under its own EHSS system. A DM-only approval may not be accepted. Dotless holds both.
What proof does Dotless have of Trakhees approval?
PCFC Certificate of Approval No. 2727, issued by Trakhees EHSS, Ports, Customs & Free Zone Corporation, for water tank cleaning services.
Which free zones do you cover?
JAFZA, Technopark (National Industries Park), Dubai Maritime City, Dubai World Central and other PCFC-controlled areas, plus mainland Dubai under our DM permit.
How soon can I get the certificate?
The certificate is issued after the cleaning and disinfection are completed and verified. Because renewals are time-bound, book ahead of your deadline.
What does the job actually involve?
A full confined-space clean, disinfection with approved chemicals, final testing, and a completion certificate — all in one scheduled visit.
