Our story

Built here.
Growing with Kenya.

Astral Industries Limited designs, manufactures, installs and maintains water storage and fabrication solutions - moulded tanks, tank structures, steel structures, fuel tanks, hot water cylinders and panels. What started as a regional operation now reaches customers across Kenya, and the company supports community work around water access in arid areas and the agricultural sector.

  1. 2004

    Astral Industries is established

    The business starts out as a regional fabrication operation on the Nairobi industrial corridor.

  2. 2006

    Formally incorporated

    Astral Industries Limited is incorporated and begins to build out its workshop capacity.

  3. 2007

    Steel tank manufacturing begins

    The first steel tanks come off the line, alongside fuel tanks, hot water cylinders and structural fabrication.

  4. 2011

    Plastic tank manufacturing begins

    Rotational moulding is added, and the Jumbo Tank range of double-layer plastic water tanks is born.

  5. 2016

    Factory expansion

    Production capacity is expanded to keep up with demand across the country.

  6. 2019

    Mombasa factory established

    A coastal factory opens, shortening the route to customers in Mombasa, Kilifi, Kikambala and Malindi.

Beyond the factory gate

Astral Industries takes part in community work around water access in arid areas, and supports the agricultural sector as part of the wider effort on food security.

Our solutions

Two ways we solve water storage.

Moulded tanks for everyday storage, and slim loft tanks for the spaces a standard tank will not reach.

Cylindrical Plastic Tanks

The tank most Kenyan homes, farms and institutions rely on. A cylindrical body spreads pressure evenly, which lowers the risk of leaks and ruptures, and the moulded plastic will not corrode.

  • Balanced pressure. The cylindrical shape distributes load evenly and minimises the risk of leaks and ruptures.
  • Corrosion resistant. Lightweight moulded plastic that will not rust, inside or out.
  • Double-layer protection. A UV-stabilised outer layer over a food-grade inner layer.
  • Low maintenance. A smooth internal surface makes cleaning straightforward.
  • 16-year warranty. Backed for 16 years from the date of purchase.

Range

300 L to 25,000 L, including short variants at 1,000 L and 5,000 L.

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 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.

  • 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 double-layer tank on the compound means the taps keep running when the mains do not.

  • 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.

Why Jumbo

Two layers. Two different jobs.

Every Jumbo plastic tank is moulded as a double-layer wall, each layer doing a different job.

  • Outer layer

    Black, for UV protection and weather resistance

    • UV stabilised so the wall keeps its strength under the Kenyan sun.
    • Blocks light, which is what keeps algae from taking hold inside.
    • Takes the knocks, the heat and the rain - this is the layer you see.

  • Inner layer

    White virgin material, food grade and anti-algae

    • Virgin material, not regrind - the only surface your water touches.
    • Smooth internal finish, so cleaning is quick and residue has nowhere to sit.
    • Bonded to the outer layer during moulding, not glued on afterwards.

16

year warranty

Terms are confirmed with your purchase documentation.

  • 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

    Two bonded layers instead of one moulded wall.

  • Low maintenance

    A smooth interior keeps routine cleaning simple.

Tank sizer

Find the right tank.

Size from the rain your roof catches, from the people or animals you supply, or straight from a capacity you already have in mind. Every figure is a planning estimate you can adjust — send the result through on WhatsApp and we will quote it.

Sets your rainfall and your delivery zone. Pick your town, or let your device find it.

100 m²

The area rain lands on, seen from above. A modest three-bedroom house is around 100 m².

Smooth and non-absorbent, so it sheds almost everything that lands on it.

Waiting on one thing

Choose where you are and we will size the tank.

Rainfall in Kenya runs from about 280 mm a year in Garissa to well over 1,500 mm in the western highlands, so the answer changes completely with where your roof stands.

From the yard

Real tanks, real factory.
