How Long Does It Take to Install a Water Tank?

August 28 2025

Large-scale tanks for mine sites and industrial facilities require careful planning, specialised equipment, and coordinated execution. Understanding the factors that influence installation time helps operators set realistic project schedules and avoid costly delays. This article will help answer the question of how long does it take to install water tanks.

Factors Affecting Installation Time

Tank Size & Capacity: The larger the tank, the longer the installation and commissioning process will take. Small to mid-sized modular tanks can be assembled relatively quickly, while high-capacity tanks designed for mine sites or industrial facilities may require weeks of construction and integration.

Site Preparation: Before the tank arrives, the site must be properly prepared. This can involve groundworks, laying stable foundations, and ensuring adequate access for installation equipment. On uneven or remote terrain, site preparation can extend the timeline considerably.

Location: External conditions often play a major role in scheduling. Remote mining sites may face longer lead times due to transport logistics. Compliance with local safety and environmental regulations must also be factored into the project plan. For example, water tanks erected near the tropics might require cyclone rating.

Customisation: Most industrial and mining tanks require more than just the tank itself. Integration with pumps, pipework, and water treatment systems adds to the installation timeline. The more complex the system, the longer it takes to commission, test, and hand over to the operator.

Typical Timelines

How long does it take to install a water tank? When planning a large-scale water tank installation, it’s important to understand the stages involved and the time each can take. While every project is unique, all involve three key steps: 1) site preparation, 2) tank construction, and 3) tank commissioning.

Site Preparation (2-3 Weeks)

Site preparation is often the most time-consuming stage. Depending on ground conditions, terrain, and civil works required, this phase can range from several weeks to a few months. Work may include earthworks, building stable foundations, ensuring drainage, and providing access routes for installation equipment.

Tank Installation (1-2 Weeks)

Once the site is ready, tank assembly begins. Timelines vary depending on the tank’s size. Smaller modular panel tanks can often be erected within a few days once delivered to site. Larger steel tanks typically take several weeks to fully assemble, particularly if they require specialist equipment and a larger installation team.

Tank Commissioning (1 Week)

After construction, the tank must be integrated with associated systems such as pumps, pipework, and water treatment equipment. Commissioning includes pressure testing, leak checks, safety inspections, and compliance sign-offs. This stage usually adds several days depending on the complexity of the system.

Efficiency Considerations

Opt for Modular Systems

Opting for pre-fabricated or modular tank designs can greatly shorten on-site installation. These systems are manufactured off-site under controlled conditions, then delivered in sections that can be quickly assembled. This approach is particularly valuable for remote mining operations where reducing time on site directly lowers costs and logistical challenges. At Allied Pumps, we use modular tank designs to ensure fast installation and reduce costs for our clients.

Choose Experienced Installers

Additionally, a skilled installation team makes a major difference in efficiency. Experienced crews are familiar with site constraints, safety protocols, and assembly techniques that streamline the process and reduce the risk of costly delays. At Allied Pumps, we have decades of experience with tanks and use a tank jacking system to increase safety and speed up installation time.

End-to-End Supply Partner

Working with a single supplier who manages design, manufacture, transport, and installation ensures a smooth, coordinated process. This eliminates the inefficiencies that can arise when multiple contractors are involved, helping projects stay on schedule and within budget. At Allied Pumps, we provide end-to-end support including design, manufacture, transport, installation, and commissioning.

Our Barrow Island Tanks Project

Barrow Island water tank

Allied Pumps was contracted to replace deteriorating tanks at a remote offshore oil and gas facility in Western Australia. The site was characterised by corrosive seawater, sewage, RO backwash, and exposure to cyclonic wind conditions.

Despite the harsh marine environment, the Allied Pumps team successfully installed five hot-dip galvanized, painted steel tanks. To ensure durability, the project incorporated specialized corrosion mitigation measures, including:

  • Sealed and painted interiors
  • Stainless steel flashings and roofing
  • Robust 4 mm RHS/SHS structural sections
  • Impact-resistant truss spacing
  • Structural assessment via finite element analysis to ensure wind resistance and structural integrity

In the end, Allied Pumps delivered the five tanks within the agreed timeline. A 1 ML stainless steel modular panel tank took only 2 weeks to install, which is impressive given its size and remote location. Follow the link to learn more about the Barrow Island project.
