The Isi digi award is presented by WISA bienially to the owner and works manager of WWTWs larger than 25 megalitres per day. During the recent WISA conference held in Mbombela, recipients of this award were announced at a gala dinner.

The award is divided into two categories, namely ‘Best Wastewater Treatment Works’ and ‘Most Improved Wastewater Treatment Works’.

In both categories, certain parametres are used during the evaluation of the WWTW, including efforts by the owner and works manager, operating efficiency, plant maintenance and servicing, laboratory control, development and improvement, general administration, housekeeping, safety, knowledge, general appearance and professionalism. In the category for ‘Best Wastewater Treatment Works’, two of ERWAT’s WWTWs received recognition; prime spot was taken by Dekema, with Rondebult also being commended.

In the category for the ‘Most Improved Wastewater Treatment Works’, ERWAT’s biggest WWTW, Waterval, was announced as the winner, while Olifantsfontein was highly commended.
