Common Water Tank Problems We Solve in Cyprus
Water storage tanks across Cyprus can accumulate sediment, sludge, deposits and other contamination over time. Tanks with poor maintenance history, limited access or long periods between cleaning can require more extensive physical cleaning before disinfection.
🧫 Sediment in the Tank
Fine sand, dirt, rust particles and mineral deposits can settle at the bottom of storage tanks. Physical cleaning removes accessible accumulated material.
🌊 Cloudy or Discoloured Water
Accumulated sediment or contamination in a storage tank can contribute to cloudy or discoloured water. Inspection helps identify whether the tank requires cleaning.
🦠 Microorganisms & Biofilm
Microorganisms and biofilm can develop on surfaces within tanks and connected water systems. Physical cleaning and appropriate disinfection can form part of the control measures.
👃 Unusual Taste or Odour
Stagnant water, sediment and other contamination can contribute to unusual tastes or odours. The cause should be assessed before selecting the appropriate corrective action.
🪨 Sludge & Heavy Deposits
Long periods without maintenance can allow heavier deposits and sludge to build up on the tank floor and other accessible surfaces.
🏚️ Unknown Maintenance History
Older tanks or tanks with no clear service history may benefit from inspection so their condition and cleaning requirements can be assessed.
Why We Use Chlorine Dioxide for Water Tank Disinfection
Physical cleaning removes accessible sediment, sludge and deposits from a water tank. Disinfection is a separate stage used to help control microorganisms after cleaning and, where appropriate, may also be applied to connected parts of the water system.
WaterFilterNet uses chlorine dioxide for applicable disinfection work. The treatment method, concentration and contact time depend on the intended application, system conditions and applicable product instructions.
What is chlorine dioxide?
Chlorine dioxide is a water-treatment disinfectant used for microbiological control in a range of water-system applications. Its suitability, concentration and contact time depend on the intended use, product authorisation and treatment conditions.
It can be used in applications including water storage tanks, pipework and distribution systems. Where a product is used for drinking-water applications, it must be authorised for the relevant use and applied according to the applicable product conditions and instructions.
🦠 Microbiological Control
Chlorine dioxide is used in water-treatment applications as a disinfectant for microbiological control.
🧱 Biofilm Control
Biofilm can develop on surfaces inside tanks and pipework. Physical cleaning removes accessible deposits, while disinfection can form part of wider measures used to control microorganisms associated with biofilm.
⚙️ Controlled Application
The treatment method, concentration and contact time are selected according to the application, system conditions and applicable product instructions.
🔧 Tanks & Pipework
For the standard residential service, chlorine dioxide treatment includes the tank and accessible internal water distribution pipework through the property’s outlets, subject to system configuration and accessibility. Commercial and more complex systems are assessed individually.
Cleaning & Disinfection Based on Cyprus Requirements and Official Guidance
WaterFilterNet.com / ERMAKO LIMITED carries out water-tank and water-system cleaning and disinfection with reference to the applicable Cyprus regulatory framework, official guidance and authorised conditions of use of the biocidal products used.
🏛 Cyprus Legionella Guidance
The Cyprus Department of Labour Inspection identifies measures including periodic cleaning and disinfection of tanks and pipework, flushing of low-use outlets, temperature control, monitoring and laboratory analysis where required.
🧾 Service Documentation
Where applicable, treatment documentation can record the disinfectant used, relevant treatment parameters, field measurements, observations and recommendations relating to the work performed.
✓ Dutrion Chlorine Dioxide – Listed in the Cyprus Biocides Register
For applicable disinfection work, WaterFilterNet uses Dutrion Chlorine Dioxide. Dutrion is listed in the Cyprus Department of Agriculture’s March 2026 register of authorised biocidal products under licence B1844.
The official register lists Dutrion for Product Types 2, 3, 4, 5, 11 and 12. Product Type 5 relates to products used for drinking-water disinfection.

⚠️ Important Note
The exact disinfection procedure depends on tank size, water usage, system design, accessibility and site conditions. Every installation is different, so the appropriate cleaning and disinfection procedure is selected according to the individual project.
Our Water Tank Cleaning and Disinfection Process
Our service follows a structured cleaning and disinfection procedure designed to remove accessible sediment, sludge, dirt and deposits before disinfection. The exact sequence can vary according to tank size, condition, access and system design.
1️⃣ Initial Inspection
The tank is inspected to assess its condition, accessibility and visible contamination before work begins.
2️⃣ Tank Draining
The tank is drained where required to allow access to internal surfaces and accumulated material.
3️⃣ Sediment Removal
Accessible sediment, sludge, dirt and loose deposits are physically removed from the tank.
4️⃣ Internal Cleaning
Tank walls, corners and other accessible internal surfaces are cleaned to remove visible residue and deposits.
5️⃣ System Rinsing
The tank is rinsed to remove loosened material before the disinfection stage.
6️⃣ Tank & Pipework Disinfection
The tank is disinfected using chlorine dioxide. For the standard residential service, treatment is also circulated through accessible internal water distribution pipework and outlets, subject to system configuration and accessibility. The treatment procedure is selected according to the application, system conditions and applicable product instructions.
7️⃣ Final Flush & Recommissioning
Following the treatment, the tank and treated accessible sections of the water system are appropriately flushed and prepared for normal operation.
8️⃣ Documentation & Recommendations
Before & after photos and a Cleaning & Disinfection Service Record document the work performed. Where relevant, we also provide condition observations and recommendations for filtration, maintenance, monitoring or further water-system investigation.
Concerned About Legionella?
Routine water tank cleaning and disinfection should not be confused with investigating or treating a confirmed Legionella problem. Legionella may be present in a storage tank, but it can also occur in downstream pipework, showers, taps and low-use outlets.
Professional cleaning can physically remove sediment, deposits and accessible contamination from the tank, while appropriate disinfection can help control microorganisms in the treated areas. However, tank cleaning or disinfection alone cannot guarantee the absence of Legionella or complete removal of established biofilm throughout an entire building water system.
Read our Legionella in Cyprus guide, learn about Legionella testing, or see how we approach Legionella treatment in Cyprus.
Cleaning & Disinfection Service Documentation
Following the standard residential service, customers receive before & after photos and a Cleaning & Disinfection Service Record documenting the cleaning and disinfection work performed. Relevant treatment details, observations and recommendations can also be recorded where applicable. This documentation confirms the service performed. It is not a laboratory water-quality certificate and does not certify the absence of Legionella or other microorganisms. Where microbiological confirmation is required, appropriate sampling and laboratory analysis are necessary.
Professional Water Tank Cleaning, Prevention & Commercial Solutions
Professional Water Tank Cleaning vs DIY Cleaning
Basic inspection and maintenance may be possible for some property owners, but thorough cleaning and disinfection of a storage tank can require safe access, removal of accumulated material, appropriate disinfection and controlled recommissioning.
| Feature | Professional Service | Basic DIY Cleaning |
|---|---|---|
| Sediment Removal | ✅ Physical removal where accessible | ⚠ May be limited |
| Tank Inspection | ✅ Included | ⚠ Depends on experience |
| Disinfection | ✅ Chlorine dioxide disinfection included | ⚠ Often not part of basic cleaning |
| Biofilm Control Measures | ✅ Cleaning + disinfection where relevant | ⚠ May be incomplete |
| Pipework Disinfection | ✅ Accessible pipework included in standard residential service | ⚠ Often not assessed |
| Service Documentation | ✅ Photos + Cleaning & Disinfection Service Record | ❌ Normally unavailable |
⚠️ Why Maintenance Matters
Sediment, sludge and deposits can build up over time. Regular inspection and appropriate cleaning can reduce heavy accumulation and make ongoing maintenance easier.
Protect Your Water Tank After Cleaning
Cleaning removes contamination and deposits already present, but it cannot prevent new sediment, dirt or rust particles from entering the system in the future. Appropriate filtration and system maintenance can help reduce future accumulation.
🚰 Filtration Before the Tank
Suitable sediment filtration before the storage tank can help reduce suspended dirt, rust particles and sediment entering the tank.
💧 Filtration After the Tank
Filtration after the tank can help capture suspended particles before the water reaches downstream plumbing and equipment.
🛡️ Additional Water Hygiene Measures
UV disinfection and other appropriate water-treatment systems can provide an additional control measure for microorganisms depending on water quality and system design.
🔧 Protect Plumbing & Equipment
Reducing suspended sediment can help protect taps, showers, boilers, heaters, washing machines, filters and other connected equipment.

Water Tank Cleaning — Frequently Asked Questions
How often should a water tank be cleaned in Cyprus?
The appropriate cleaning frequency depends on tank condition, water source, usage, environment and maintenance history. Regular inspection can help determine when cleaning is required.
What are the signs that a water tank may need cleaning?
