DM & Waste, STP & ETP Water Storage Tanks for Industrial Plants
Storage for demineralised water and for wastewater streams at sewage and effluent treatment plants — with lining, materials and connections reviewed for the water each tank will hold.
- Stream-specific review
- Process-based sizing
- Inspection access
One tank system, very different waters
Demineralised (DM) water is used wherever dissolved minerals must be controlled — boiler feedwater, power plants, pharmaceutical and chemical processing. Wastewater, at the other end of the plant, is collected, held and treated in sewage treatment plants (STP) and effluent treatment plants (ETP) before reuse or discharge.
Both need storage — but the requirements differ. DM water must not be contaminated by the tank; wastewater must be contained safely, with a lining and fittings suited to its characteristics.
AVM Prefabricated Modular Tanks LLP offers customised prefabricated tanks for these applications. We consider the water characteristics, operating conditions, capacity and internal material compatibility before a configuration is selected.
Features of DM, Waste Water, STP & ETP Tanks
Customised capacity
Dimensions and volume planned around process demand or treatment stage.
Material compatibility
Internal lining selected for the specific water stream.
Corrosion protection
External protection suited to the installation environment.
Modular construction
Prefabricated steel panels for planned assembly.
Inspection access
Manholes, access ladders and inspection provisions.
Project-based design
Configured to site requirements and process specifications.
Where these tanks are used
Applications to be confirmed with AVM for each project include:
- Boiler feedwater (DM water)
- Power & process plants
- Pharmaceutical & chemical industries
- Sewage treatment plants (STP)
- Effluent treatment plants (ETP)
- Treated water storage for reuse
- Industrial water treatment facilities
What to consider before selecting a tank
Water characteristics
Define purity for DM water, or the composition and temperature of the wastewater stream.
Wetted material compatibility
Lining, gaskets and fittings must suit prolonged contact with the stored water.
Treatment stage
Equalisation, holding and treated-water tanks have different sizing needs.
Inspection & cleaning
Plan access for cleaning, sludge removal or quality checks as the stream requires.
Different streams need different specifications
A tank that suits treated water is not automatically suitable for raw effluent, and a regular industrial tank is not necessarily suitable for DM water. The internal surface, liner, fittings and connections must be compatible with the specific stream.

Why Choose AVM for DM & Wastewater Storage?
Different streams have very different requirements, so each tank should be planned around the water it will hold rather than a one-size configuration.
AVM offers customised prefabricated tanks with project-specific dimensions, material selection and layout planning. Our technical team can review your treatment process to discuss the right storage configuration.

Frequently asked questions
A tank designed to store demineralised water used in industrial processes where dissolved mineral content and ionic contamination must be controlled.
Prefabricated tanks can be considered for STP and ETP storage duties. Suitability depends on the stream characteristics, liner and fittings, and is confirmed by AVM for each project.
Not necessarily. Its internal surface, coatings, liner, fittings and connections must be compatible with the specified DM water purity.
The stream to be stored, its characteristics and temperature, required capacity, treatment stage and connection requirements.
Yes. Capacity, dimensions, configuration and material selection can be considered for the process.
