What the installation covers
Roof and underground tank installation with all pipe and pump connections included
What it covers
Underground tank construction
Watertight underground tank built with access hatches and rising main connected
Inlet and supply lines
Mains supply connected to tank with float valve and isolation fitted
Overflow and drain lines
Overflow routed away from the building at correct fall to prevent backflow
Pump connection
Transfer or pressure pump connected to tank and tested under load
System pressure test
Full network pressure test after installation confirms every joint holds
How the job runs
First contact
Call or WhatsApp us with building type and number of units
Site assessment
Technician visits to assess required capacity and pipe routes
Preparation and supply
Tank specification and materials confirmed and readied before installation day
Installation and connection
Tank set, pipes run, pump and isolation valves all connected
Test and handover
Full pressure test and float valve check before handover
Signs you need a new tank
Tank is cracked or weeping
Damp marks below a roof tank or unexplained level drop without usage point to a cracked tank wall
Weak pressure despite full tank
A full tank with low pressure often means the tank capacity or pump is no longer matched to the building demand
Old tank with internal corrosion
Rust-coloured water or a metallic smell from old iron tanks is a clear sign the tank must be replaced
New building with no tank
A new build or added floor with no tank yet needs capacity assessed and tank fitted before occupation
Before you call, have this ready
Tank type you need
Know whether you need a roof tank or an underground tank as each requires different site preparation
Number of floors and units
The number of floors and residential units determines the correct tank capacity before ordering
Location of the existing pump
Knowing where the existing transfer or pressure pump sits lets the technician plan the new connection route
Roof or ground access
Confirm the stairway or roof hatch is clear because installing a roof tank requires lifting materials to height
How a tank installation is done right
Work begins with an assessment of the required capacity based on the number of floors, units and expected daily demand. An undersized tank causes pressure drops during peak hours, while an oversized one lets water sit too long and affects quality. Once capacity is confirmed, the correct position on the roof or in the ground is chosen with attention to structural load distribution and the shortest practical pipe route.
Roof tanks are set on a raised support base that allows drainage for cleaning and eases future maintenance access. Underground tanks require a reinforced concrete pit with internal waterproofing and correctly sized access hatches. In both cases, PPR supply, overflow and return lines are run, float and isolation valves are fitted, and the suction line is connected to the transfer pump that feeds the building's internal network.
Once all connections are made, a pressure test is run across the full network to confirm every joint holds before work is closed up. The test also verifies that the float valve cuts off cleanly at the correct fill level and that the overflow discharges at a sufficient fall. Kuwait's high summer temperatures mean exposed roof pipework must be in heat-resistant material, as standard pipe grades soften and fail much sooner under direct sun.

What decides the price
No fixed price list applies; these factors shape the quote for each installation
Tank capacity and count
Larger or multiple tanks raise material and labour costs significantly
Roof or underground
Underground tanks require excavation, concrete work and waterproofing unlike roof tanks
Pipe run length
Longer supply and overflow runs require more pipe, fittings and labour hours
Existing pump condition
A new tank that needs a different pump specification adds the pump cost to the quote
Access difficulty
High rooftops or confined spaces increase working time and may require lifting equipment

What is the difference between a roof tank and an underground tank, and which is better for my house?
A roof tank is easier to access for maintenance but exposed to Kuwait's summer heat. An underground tank keeps water cooler but always needs a pump to deliver pressure. The right choice depends on available roof space, number of floors and the existing pump arrangement.
What capacity is right for a two-floor house?
There is no single answer; correct capacity depends on the number of occupants, bathrooms and the pump system. Capacity is determined during the site visit after reviewing actual daily demand, not from a fixed formula.
Does underground tank installation require major excavation?
Yes, an underground tank requires excavation to the right dimensions and a concrete pit with waterproofing. The scale of work depends on tank size, ground conditions and equipment access to the site.
Can a new roof tank be installed without replacing the existing pump?
If the existing pump specification matches the new tank size it can remain in place. The technician checks pump compatibility during the site visit and advises whether any adjustment is needed.
Why does roof tank water get so hot in summer?
Exposed roof tanks in Kuwait absorb direct sun and retain heat well into the night. Installing an insulated tank or fitting a reflective cover significantly reduces water temperature in the system.
Do you install tanks in residential complexes and commercial buildings?
Yes, installations are carried out in houses, apartments, residential complexes and commercial buildings across all 6 Kuwait governorates.
