Public Notice: Addressing sewer odours in Pacaltsdorp, Rosedale, and Thembalethu
We are aware of the occasional sewer odour affecting the Pacaltsdorp, Rosedale, and Thembalethu areas in recent months. After investigating, we found that the issue is primarily due to challenges with the oxygen supply demand system at the Outeniqua Wastewater Treatment Works (WWTW) and the additional residual (sludge) being received from the Water Treatment Works (WTW) situated in Denneoord.
What Is Causing the Odour?
• The WTW is currently discharging residual (sludge) into the wastewater system. This is a temporary measure until the WTW upgrade is complete, which will include a proper residual (sludge) dewatering handling facility.
• The Outeniqua WWTW is struggling to properly treat this waste due to two broken oxygen supply pieces of equipment , which help break down organic matter and reduce odours.
• Repairing this oxygen supply equipment is complex, and no contractors in South Africa are able to assist. We are now working on having them repaired abroad. In the meantime, a new oxygen supply demand system has been ordered as a temporary solution.
What Are We Doing About It?
• We have adjusted the treatment process to divert most of the flow to the recently built treatment module which operate more effectively.
• This change has already reduced the odour, and the situation will continue to improve as the system stabilises.
• The new oxygen supply equipment is expected to be in place by May 2025, ensuring better long-term odour control.
We appreciate the public’s patience and understanding as we work to resolve this issue.

Openbare Kennisgewing: Hantering van rioolreuke in Pacaltsdorp, Rosedale en Thembalethu
Uitgereik deur George Munisipaliteit 2 April 2025
Ons is bewus van die rioolreuk wat af en toe die afgelope maande in die gebiede van Pacaltsdorp, Rosedale en Thembalethu voorkom. Na ‘n ondersoek het ons bevind dat die probleem hoofsaaklik veroorsaak word deur uitdagings met die suurstofvoorsieningstelsel by die Outeniqua Afvalwaterbehandelingsaanleg (WWTW) en die bykomende afval (modder) wat vanaf die Waterbehandelingsaanleg (WTW) in Denneoord ontvang word.
Wat veroorsaak die reuk?
• Die WTW stort tans afval (modder) in die rioolstelsel af. Dit is ’n tydelike maatreël totdat die WTW-opgradering voltooi is, wat ’n behoorlike afvalontwateringsfasiliteit sal insluit.
• Die Outeniqua WWTW sukkel om hierdie afval behoorlik te verwerk weens twee stukkende suurstofvoorsienings-eenhede, wat help om organiese materiaal af te breek en reuke te verminder.
• Die herstel van hierdie toerusting is ingewikkeld, en geen kontrakteurs in Suid-Afrika kan hiermee help nie. Ons werk tans daaraan om dit in die buiteland te laat herstel. Intussen is ’n nuwe suurstofvoorsieningstelsel bestel as ’n tydelike oplossing.
•
Wat doen ons daaromtrent?
• Ons het die behandelingsproses aangepas om die grootste gedeelte van die vloei na die nuutgeboude behandelingseenheid te herlei, wat meer doeltreffend werk.
• Hierdie verandering het reeds die reuk verminder, en die situasie sal bly verbeter namate die stelsel stabiliseer.
• Die nuwe suurstofvoorsieningstoerusting word teen Mei 2025 verwag, wat beter langtermynbeheer oor die reuk sal verseker.
Ons waardeer die publiek se geduld en begrip terwyl ons hierdie kwessie oplos.
