Why Jumbo

Three layers. One strong tank.

Every Jumbo plastic tank is moulded as a three-layer wall: black outside for UV, a middle layer, and white food-grade virgin material inside.

16year warrantyTerms are confirmed with your purchase documentation.

  1. Outer layer

    Black, for UV protection and weather resistance

    UV stabilised, so the wall keeps its strength under the Kenyan sun — and opaque, which is what keeps algae from taking hold inside. This is the layer you see, and the one that takes the knocks.

  2. Middle layer

    Between the outer and inner layers

  3. Inner layer

    White virgin material, food grade and anti-algae

    Virgin material, not regrind — the only surface your water touches. Smooth enough that residue has nowhere to sit, and bonded into the wall during moulding rather than glued on afterwards.

Built into every Jumbo water tank.

  • Air ventilation

    Vented so the tank breathes as water moves in and out.

  • Food grade

    Non-toxic inner surface for household water storage.

  • UV stabilisation

    The outer wall is built to sit in direct sun.

  • Built stronger

    Three bonded layers instead of one moulded wall.

  • Low maintenance

    A smooth interior keeps routine cleaning simple.

Where they work

One tank range, three very different days.

The sizing is the same exercise whether it is a five-person household or a 400-pupil school: how much water a day, and how long you want to hold it.

  • A family sitting on the steps of their home holding glasses of water, with a Jumbo Tank mounted on a plinth beside the house.

    Homes and families

    A three-layer tank on the compound means the taps keep running when the mains do not.

  • A farmer standing at the edge of a drip-irrigated vegetable field at sunrise, with a Jumbo Tank on a raised stone stand behind him.

    Farms and irrigation

    Storage that carries a shamba through a dry stretch, feeding drip lines and livestock troughs on gravity.

  • Students washing their hands at taps fed by a Jumbo Tank on a raised plinth, on a university campus.

    Estates and institutions

    Schools, clinics, guest houses and apartment blocks, sized on daily demand rather than guesswork.

Tank Sizer

Not sure what size you need?

The Tank Sizer asks what the water is for and works the capacity out from there — household, livestock, irrigation, or the rain off your roof.

All FAQsContact and directions

  • Do you deliver countrywide?

    Yes. Delivery is organised in four zones running from Nairobi and the immediate 50 km radius out to roughly 400 km, and the coastal outlets are served as well. Share your delivery location with your enquiry and our team will confirm what is possible for your area.

  • How long does delivery take?

    Jumbo Tank's August 2026 published list gives a maximum of 7 working days within about 50 km of Nairobi and at our coastal outlets, and 14 working days further out. Actual timing depends on stock, load and destination, so it is confirmed with your final quote rather than promised up front.

  • What warranty comes with a Jumbo Tank?

    Jumbo Tank plastic tanks carry a 16-year warranty. Warranty terms and conditions are confirmed with your purchase documentation.

  • How many layers do the plastic tanks have?

    Jumbo plastic tanks have three layers. The outer black layer is UV stabilised and takes the weather; the inner white food-grade layer is the surface your water sits against; a middle layer sits between them.

  • Are the tanks available in other colours?

    Black is the standard product colour. Tanks in other colours can be produced on special order - talk to our team about quantities and lead time.

  • How does the tank sizing estimate work?

    The Tank Sizer multiplies your daily water demand by the number of days of storage you want, adds a fixed 15% safety buffer, and then picks the smallest standard tank that meets the result. It can also size from the rain your roof catches, or from a capacity you already have in mind. Every planning figure it uses is shown on screen, and the daily use and the days of storage can be edited.

  • Does the Tank Sizer tell me the price?

    Not on this website. The Tank Sizer works out the size you need, then links that size straight to Astralind (astralind.com), the Astral Industries online shop, where its price is shown and Jumbo Tanks are bought — use the Buy this size on Astralind button under your result. If you would like us to confirm delivery to your site first, send the recommendation through on WhatsApp or call us. This website is a showroom: orders and payments are taken on Astralind.

  • Where are the Jumbo Tank offices and factories?

    The head office is at Astral Plaza, Old Mombasa Road, Kyang’ombe, Nairobi. There are factory outlets at Isinya in Kajiado County and at Kikambala in Kilifi County. Use the Get Directions links in the contact section for a map pin.

  • How do I request a custom steel tank or pre-engineered structure?

    Send an enquiry with your capacity, site and timeline, or call the team directly. Steel tanks, steel towers and pre-engineered structures are designed to your specification and quoted individually - they are not priced by the Tank Sizer.
