Internal Reinforcement system provides the following
Free capacity design
Using panels of various sizes, the DOHA Clean Tank utilizes horizontal and vertical space at the maximum and those are suitable for an underground reserve tank of large capacity. It operates a corner-type system.
Large capacity type:
Best Hygienic Properties
With the use of excellent corrosion-resistant panels, the surface of the tank is uniformly smooth without any moss growth and therefore, enables long-term use as the panels inhibit the proliferation of bacteria and other various germs by perfectly blocking all light frome outside.

Performance evaluation criteria of the panel
LONG-TERM DURABILITY TEST (FIELD TEST)
Generally, there is more than one water depletion and filling up a water tank per day, on the average. Therefore, if the tak is used for 15 years, approximately 4000 times of water circulation would occur and the tank would undergo about 4000 repetitive loads. Through the field test before launching new products into the market, the Hi Tank undergoes actually expected repetitive loads by letting the water circulate for 6 months day and night using two tanks. After checking for water leakage and other defects from such tests to guarantee safety and endurance, we launch the product into the market.
