Owing to growth in the north-eastern fringes of East London, Buffalo City Municipality felt it necessary to provide elevated storage at the area's service reservoir site. This would provide supply security and reduce the hydraulic load on the ageing bulk-supply mains.

A single aerobic reactor is currently installed at the Quinera WWTW. It is aerated by means of four surface mechanical aerators mounted on concrete bridges, driven through gearboxes by 35 kW motors. The WWTW currently receives an inflow of between 6 and 7 Mℓ/d ADWF, but will be expanded to a capacity of 18 Mℓ/d ADWF. This will require the addition of a second aerated reactor rated at 9 Mℓ/d, and increased aeration capacity of the existing reactor to the same level.

A pump replacement contract with Eskom's Duvha power station was secured by Weir Warman Africa Witbank. The contract covers the refurbishment, supply and exchange of ash pumps on an ''as and when'' required basis. ''Under this three-year contract we will have the appropriate Warman pumps at the branch at all times to facilitate a quick change when it becomes necessary, thereby minimising plant downtime,'' says Nico Smit, Witbank branch manager at Weir Warman Africa.
