Water tanks represent an essential solution in industrial, agricultural, and civil contexts where it is necessary to store, distribute, or recover water resources with operational continuity. From rainwater harvesting to accumulation for fire-fighting systems, and the storage of potable water in environments with supply interruptions, these containers perform critical functions in modern infrastructure. Choosing an appropriate tank directly influences the efficiency of business processes, the quality of the stored water, and the overall sustainability of the plant.
The variants available in our catalog range from small polyethylene tanks to large-capacity galvanized sheet metal structures, each designed to meet specific volume requirements, installation types, and applicable regulatory standards.
A water tank allows for addressing critical situations such as water supply interruptions, sudden consumption peaks, or the need for accumulation for irrigation and fire-fighting systems. In HoReCa contexts, for example, the availability of a water reserve ensures continuity in catering services even during external service failures, while in the industrial field, tanks support production cycles that require constant volumes. The use of tanks also allows for implementing water-saving strategies, such as rainwater harvesting, reducing consumption and operational costs in the long term. Finally, in geographical situations where supply is irregular, having a storage structure represents a strategic resilience measure to guarantee operational autonomy.
The presence of a correctly sized tank also optimizes pumping and distribution systems, as it allows for reducing pressure peaks and extending the life of connected systems. Furthermore, many modern tanks integrate accessories such as inlet filters, sampling points, and inspection hatches, features that simplify maintenance and ensure hygienic management of the stored resource.
Our catalog features tanks made of three main materials, each with specific constructive characteristics. Polyethylene tanks (PE and LLDPE) represent the lightest and most versatile solution: they resist corrosion, are easily transportable, and are available in capacities from 300 to over 1000 liters. Their structure allows for both vertical and horizontal installations, as well as versions designed for underground placement. Galvanized steel tanks, on the other hand, are suitable for industrial and long-lasting applications: the galvanization process protects against oxidation and deterioration, making them particularly suitable for outdoor environments or critical environmental conditions. These models are available in cylindrical (vertical and horizontal) and parallelepiped configurations, with capacities reaching 3000+ liters. Some models feature inspection hatches of 240 or 320 mm in diameter, facilitating cleaning and maintenance operations.
Each type of material offers specific advantages and limitations depending on the application context. Polyethylene is ideal where weight is a logistical constraint or where frequent cleaning operations require easy access. Galvanized steel prevails in large-volume fixed plants where structural robustness and durability are prioritized over lightness. There are also "palletized" tank configurations, designed with bases that facilitate movement via pallet jacks or forklifts, a practical solution for industrial environments where operational flexibility is frequently required.
Selecting a tank requires, first of all, clearly defining the necessary volume, calculated based on daily consumption, withdrawal frequency, and the maximum desired duration of autonomy. In contexts such as pharmacies, medical offices, or small restaurants where usage is moderate but regular, tanks between 500 and 700 liters are generally sufficient. Medium-sized companies or facilities with marked consumption peaks must consider capacities exceeding 1000 liters, possibly evaluating the opportunity to install multiple modular units rather than a single large-volume container. A second critical aspect concerns available space: vertical tanks are preferable where the ground footprint is limited, while horizontal solutions adapt better to rooms with reduced height or wide corridors.
The choice of material depends on the quality of the water intended for storage and the expected duration of the installation. If the water is potable and must be stored for a long time, galvanized steel ensures a better barrier against pathogens and environmental contamination, albeit with a higher initial investment. Polyethylene is sufficient for most non-potable uses (rainwater, non-critical industrial processes), with the advantage of reduced costs and ease of installation. A frequent mistake is undersizing the volume: an apparently oversized tank offers operational stability and allows for facing unforeseen consumption peaks without hydraulic stress. Finally, checking compatibility with local regulations (UNI EN 12285 for polyethylene tanks, UNI EN 1092-1 for fittings, regional construction regulations) is an indispensable step before purchasing.
Water tanks are subject to technical regulations that guarantee safety, hygiene, and durability. The UNI EN 12285-1 standard governs plastic tanks for potable water and rainwater, defining construction, resistance, and durability requirements. Regarding materials, the European standard EN 12285-2 specifies standards for steel tanks, while UNI certifications ensure that the polyethylene used is suitable for contact with water intended for human consumption. Furthermore, in Italy, Legislative Decree 31/2001 (implementation of Directive 98/83/EC) establishes microbiological and chemical quality criteria for stored water, making the selection of inert and contamination-resistant materials mandatory.
Specific requirements emerge depending on the context of use: for tanks in public environments (hospitals, schools, sports facilities), a CE declaration of conformity according to current construction regulations is required. Palletized and mobile tanks must comply with standards for stability and robustness of support structures (UNI EN ISO 4413 for mobile systems). The technical documentation provided with each product must include certificates of conformity, construction specifications, and installation and maintenance instructions. Periodic quality control of the stored water is also a practical requirement: regulations recommend checks at least every six months for potable water tanks to identify early phenomena of sedimentation, algal bloom, or internal wall corrosion.
Explore all products in the category and compare the available solutions to find the one best suited to your operational context, considering capacity, material, configuration, and specific regulatory requirements for your application.
Polyethylene is lighter, more versatile, and corrosion-resistant, ideal for temporary installations or where mobility matters. Galvanized steel offers greater durability, structural robustness, and better hygienic protection for long-term potable water storage, but involves higher weight and costs. The choice depends on the lifespan of the system and the quality of the water to be stored.
For small restaurants (20-40 covers), 500-700 liters are sufficient. Medium facilities (50-100 covers) require 1000-1500 liters. The basic formula is: number of people × average daily consumption (30-50 liters per person) × number of days of desired autonomy. It is always advisable to oversize by 20% to manage peaks.
Yes, provided they are made of UNI EN 12285-1 certified polyethylene for food use. The material must be inert, UV-resistant (if exposed), and free from toxic substances. Always check the CE declaration of conformity and specific certifications provided by the manufacturer before purchasing.
Vertical tanks require less ground space and facilitate the sedimentation of impurities at the bottom, making them excellent for environments with limited surface area. Horizontal tanks are more stable, require less installation height, and are preferable where the ceiling is low. The choice depends on room dimensions and accessibility for maintenance.
Routine maintenance (visual inspection, internal cleaning) has low costs and should occur every 6-12 months. Plastic tanks require minimal intervention; galvanized steel ones may need protective coatings every 5-10 years. Extraordinary cleaning (degreasing, disinfection) costs range from 200 to 800 euros depending on capacity.
No. Rainwater has fewer regulatory constraints as it is intended for secondary uses (irrigation, cleaning). A plastic or untreated steel tank with protection from light and contaminants is sufficient. Potable water, however, requires specific certifications and inert materials to avoid the release of harmful substances.
Underground tanks are designed to withstand soil pressure and still require excavation and civil works. They are only recommended if underground placement is already planned during the system design phase. For contingent needs, above-ground solutions remain more economical and practical to manage over time.
Legislative Decree 31/2001 (implementation of Directive 98/83/EC) establishes microbiological and chemical parameters. Quarterly checks are recommended for old tanks and annual checks for new systems. Certified laboratories can analyze samples to detect bacteria, hardness, pH, residual chlorine, and other critical characteristics.
