Vertical Water Tanks UAE
The standard rooftop tank configuration for UAE properties — vertical orientation maximises storage volume within a minimal floor footprint, available in PVC and GRP across the full UAE capacity range.
Vertical water tanks stand upright with their circular cross-section, storing the maximum volume of water within the smallest possible floor footprint. This geometry is the reason vertical tanks are the standard configuration for UAE rooftop plant rooms, where the available area is limited but headroom is generally adequate. KHAZAAN supplies vertical tanks in two materials across the full UAE capacity range. PVC polyethylene vertical tanks are available from 50 USG to 6,000 USG, covering all residential applications from a single apartment to large villas, and light commercial buildings up to mid-size office or retail premises. GRP fiberglass vertical tanks are available from 300 USG to 20,000 USG, covering the large commercial and industrial requirements of hotels, hospitals, labour camps, apartment towers, and infrastructure projects. Both materials carry UAE Municipality Certification for potable water storage. PVC tanks carry a 5-year warranty; GRP tanks carry a 2-year warranty. KHAZAAN stocks a comprehensive range of both types for fast delivery across all 7 UAE emirates.

Key Benefits
Who Uses This Tank?
Rooftop Plant Rooms
Vertical tanks are the first choice for UAE rooftop installations where floor area is limited by the building footprint. The taller profile fits within standard parapet heights and delivers efficient storage within the available space.
Large Commercial and Industrial Storage
GRP vertical tanks from 1,000 USG to 20,000 USG serve hotels, hospitals, shopping centres, and industrial facilities where a single large-capacity tank provides main building water storage.
Ground-Level and Plant Room Installations
Where rooftop installation is not practical, vertical tanks installed at ground level or in plant rooms with pump distribution systems provide the same space efficiency inside the building envelope.

Frequently Asked Questions
What is a vertical water tank?
A vertical water tank stands upright, with its circular base on the ground or support structure and its cylindrical body rising to a dome or flat top. The height of the tank is greater than its diameter. Vertical tanks are the standard configuration for UAE rooftop and plant room water storage because they store large volumes of water within a small floor footprint.
What sizes are vertical water tanks available in UAE?
PVC polyethylene vertical tanks supplied by KHAZAAN are available from 50 USG (190 litres) to 6,000 USG (22,700 litres). GRP fiberglass vertical tanks are available from 300 USG (1,135 litres) to 20,000 USG (75,700 litres), with larger custom sizes available for infrastructure and industrial projects.
What is the difference between vertical and horizontal water tanks?
Vertical tanks have a smaller floor footprint and greater height. They store more water per square metre of floor area and are the standard choice for rooftop installations where floor area is limited. Horizontal tanks have a lower profile but larger footprint. They are used where headroom is restricted — low-ceiling plant rooms, under-stair positions, or transport applications where height is constrained.
Which vertical tank material is best for UAE: PVC or GRP?
For capacities up to 2,000 USG, PVC polyethylene is generally the better value choice for UAE rooftop installations, with 5-layer specification recommended for direct sun positions. For capacities above 3,000 USG, or where maximum service life and structural strength are required, GRP fiberglass is the appropriate material. For in-between capacities of 2,000 to 3,000 USG, both materials work well and the choice depends on budget and service life expectations.
Are vertical water tanks UAE Municipality Certified?
Yes. All vertical water tanks supplied by KHAZAAN — both PVC polyethylene and GRP fiberglass — carry UAE Municipality Certification for potable water storage. Certification confirms compliance with UAE Standard ES 5775 covering material safety, UV resistance, and structural adequacy.
What warranty do vertical water tanks carry?
PVC polyethylene vertical tanks supplied by KHAZAAN carry a 5-year manufacturer's warranty against defects in materials and workmanship. GRP fiberglass vertical tanks carry a 2-year manufacturer's warranty.
Can vertical tanks be installed underground?
Standard vertical polyethylene and GRP tanks are designed for above-ground installation and are not rated for underground burial. Underground water storage requires purpose-designed tanks with reinforced wall construction to resist soil pressure from all sides. KHAZAAN supplies dedicated underground polyethylene tanks from 365 USG to 2,300 USG.
How do I choose the right vertical tank size for my UAE property?
A sizing guide for UAE properties: studio or 1-bedroom apartment, 100 to 200 litres; 2 to 3 bedroom villa, 500 to 1,000 litres; 4 to 5 bedroom villa, 1,000 to 2,000 litres; large villa 6+ bedrooms, 2,000 to 5,000 litres; small commercial building or labour camp, from 5,000 litres upward. WhatsApp KHAZAAN on +971509583173 for a personalised sizing calculation.
What support do vertical tanks need at installation?
Vertical tanks should be installed on a level, solid concrete plinth that is at least as large as the tank base diameter. The plinth must be structurally rated for the full filled weight of the tank — a 1,000 USG (3,785 litre) tank weighs approximately 3,800 kg when full. Tanks above 2,000 USG on rooftops typically require a structural engineering review before installation.
