Planned Manufacturing, Safe Installation

How Does the Process Work, From Production to Installation?

1

Engineering and Production Planning

Capacity, intended use, the liquid to be stored, and site conditions are evaluated. The appropriate material, tank dimensions, and technical components are determined, and a production plan is prepared.

2

Controlled Manufacturing and Preparation

The modular parts that make up the water tank are manufactured to the defined technical criteria. Once material, dimension, connection, and surface checks are complete, the products are prepared for shipment.

3

Shipment, Installation, and Commissioning

Tank components are delivered to the site and installed by professional teams. Once connections and system checks are complete, the tank is safely made ready for use.

Frequently Asked Questions

Browse the answers to the most common questions about choosing a water tank, determining capacity, and the manufacturing, delivery, and installation processes.

The right tank is chosen based on intended use, the liquid to be stored, required capacity, application area, and site conditions. Kolleksan evaluates domestic, industrial, and agricultural needs to determine the water storage solution best suited to your project.

Kolleksan modular water tanks can be engineered from 2 to 20,000 tons, depending on different usage needs. The tank’s dimensions and technical specifications are determined according to the required capacity and application area.

Manufacturing and delivery times can vary depending on the tank’s capacity, material choice, project specifications, and installation conditions. Once the technical details are finalized, the production, shipment, and installation schedule is shared with the customer.

Yes. Shipment and on-site installation of tank components are carried out by professional teams. Once system checks are complete and the tank is ready for use, after-sales technical support is provided as needed.

The material is determined by the purpose of use of the water, hygiene expectations and site conditions. Galvanized steel is an economical and durable solution for fire water, process water and industrial storage. Stainless steel (AISI 304 / AISI 316) stands out in projects that require high corrosion resistance and a cleanable surface. See our stainless steel water tanks and steel water tanks pages for details.

In everyday language they mostly describe the same product. A system in which water is stored in a fixed structure is called a water tank or water storage tank. Kolleksan produces modular water tanks in steel and stainless steel options, in project-specific capacities. See our water tank guide for details.

Kolleksan’s product range consists of fixed modular water tanks assembled on site. Vehicle-mounted water tankers are outside this range; in projects where water is transported, storing the transported water in a fixed modular tank can be a complementary solution.

Yes. Kolleksan steel water reservoirs are engineered for irrigation and rainwater with a modular steel shell, a reinforced PVC liner and a protective felt. See our steel irrigation reservoir page for details.
