Project Detail
NamWater supplies bulk potable water to Outapi town, as well as the surrounding areas. Raw water is withdrawn from the Calueque-Oshakati canal and is treated at the Outapi Water Treatment Works (WTW). The capacity of the plant was to be increased from 105 m3/hr to 283 m3/hr, but during the course of the project, this was increased to 438 m3/hour. Based on investigations by the team, it was decided to undertake the construction of a new “conventional” plant rather than upgrade the existing “package” plant.
The main elements in the design were the abstraction and inlet works, chemical dosing building, flocculation channel, sedimentation tanks, rapid sand filters, chloring building and upgrade of various pumping and piping systems.
The total estimated construction cost for the new Outapi WTP is N$ 112million (VAT Excl) and it is estimated that the construction can be completed within an 18 month period.
