Sun Tough Water Tanks
How does our harsh desert sun affect the lifespan of typical poly water tanks? Most other water tanks you can buy on the market are crafted from a type of plastic that is vulnerable to sun (UV) damage. When exposed to direct or indirect sunlight, these tanks may experience surface chalking as the polymers undergo oxidation. Over time, this exposure can lead to degradation, making the material brittle and prone to cracking. Additionally, UV light can accelerate color fading.
Fortunately, advancements in tank manufacturing have led to the inclusion of UV stabilisers in the production of poly storage tanks, such as rainwater tanks. All of our Rainwater Harvesting and Poly water tanks are crafted from a superior material that withstands full desert sun for decades. These stabilisers are added during the moulding process of polyethylene, helping to protect the integrity of the tank.

UV Absorbers
These substances absorb harmful UV light, converting it into heat and evenly dispersing it throughout the tank. Common chemical compounds like benzophenones, benzotriazoles, and hydroxyphenyl triazines are effective UV absorbers.
(HALS)
Hindered Amine Light Stabilizers (HALS). Unlike UV absorbers, HALS do not absorb UV radiation directly. Instead, they work by inhibiting degradation, targeting free radicals that can lead to oxidation.
Exterior
Our desert tan colored exterior is designed to reflect sunlight but also to blend in well with desert landscaping and remain neutral in your urban project. This exterior has all our fancy sun protective tech in it.
Interior
The black interior is designed to be safe for drinking and to prevent light from reaching the water column. This ensures that even in bright, direct sun conditions your tank will remain algae free.
Designed For Your Desert
Both types of stabilisers redirect the damaging effects of UV light away from the underlying polymers and colorants, ensuring that your poly tank is well-protected. When you choose a UV-stabilised poly tank, you can be assured of its durability in sunny conditions. One way to identify whether a tank is UV stabilised is by its finish: a glossy tank typically indicates UV stabilization, whereas a matte finish may mean it lacks this protection.
