WEIDA is the region’s producer of the largest polyethylene tanks. These include both aboveground and underground PE tanks.

i.	Aboveground PE Storage Tanks

WEIDA produces aboveground water storage tanks in a singlepiece molding up to 60,000 litres using its proprietary rotomolding technology. The tank is This technology has been WEIDA’s key technological expertise providing WEIDA with the clear edge over smaller tank rotomolders who can only produce tanks of limited capacities.

WEIDA has the technology and capability to

• • •

Design and manufacture its own molding machinery and moulds. Formulate and produce its own polyethylene with compound better mechanical strength and weathering properties. Manufacture large PE storage tanks with stratified wall thickness to optimise weight distribution for cost and design efficiency.

 

ii.	Underground PE Storage Tanks

Single units of tanks are produced in modular form and joined together to make underground tanks of capacities up to 100,000 litres for sewage and rainwater storage/treatment purposes.

The complex manufacturing technology to produce these tanks uniquely combines the rotomolding process, HDPE welding
technologies and pipe extrusion process.

WEIDA’s team of engineers are very well-versed with the field applications of underground PE tanks in the engineering systems design for water treatment and sewerage treatment plants.
