Pemba Island, part of the Zanzibar Islands, is a remarkable place. The traditional economy of rich fishing grounds and growing cloves has recently been boosted through the rapid rise of tourism. All these activities depend on the island’s value as an environment of exceptional beauty and purity – but more visitors mean more sewage and a corresponding growth in environmental risk.
Wavin products have been an enormous advance on traditional civil engineering materials. Since the programme went live in 2009, we have not experienced a single problem in the operation of the sewerage system.Johan Anneveldt , Aqua4All
