The Weholite system, which has capacity to store up to 940m3 of water, comprises of a 6-leg attenuation tank of 2.2 metre diameter HDPE pipe, fitted with fabricated manifolds at each end and fully welded in order to ensure resistance to ground settlement and to maintain structural integrity under unique loading conditions.
The welded joints ensure that the HDPE pipe becomes a homogenous pipeline, capable of withstanding any ground settlement without compromising its structural integrity.
