In collaboration with the Department of Minerals and Energy (DMRE), we  supported a pilot project which installed 200 solar water heaters in Nelson Mandela Bay Metro Municipality. To review the pilot project, SAGEN commissioned a study that investigated the impact of solar water heater use by low-income households over a period of one and a half years.  The results presented by the study emphasised the importance of hot water for households and the impact of energy consumption on household budgets.  The impact assessment concluded that the use of solar water heaters positively impacted on recipient households through the reduction in energy consumption and resulting monetary savings of R103 per month on average were recorded. Solar water heaters also saved time and improved the feeling of well-being through having hot water readily available.

The purpose of this guideline is to provide an overview and methodology description of how to perform an energy efficiency audit at a waste water treatment plant. Specific focus is placed on how to execute an audit with its associated calculations and compiling an informed and effective audit report. Two case study audits are also included as examples to the guideline user on how the information in the guideline is applied in practice, as demonstrated at two municipal WWTWs. The guideline serves as the basis for a training course to establish a standardised methodology for conducting energy audits in the WWTW sector, as well as to develop capacity and skills to perform such an audit.  The guide covers the following topics:

• Understanding of the purpose and focus areas of a WWTW EE Audit ,
• Understanding of the typical treatment processes’ EE impact,
• How to approach a WWTW EE Audit,
• How and where to obtain information,
• How to process the obtained information,
• How to go about implementation of the findings,
• What targets can reasonably be expected.

This guideline is meant to be a resource for decision-makers, managers and operational staff who are responsible for the planning, management, maintenance and operation of municipal wastewater treatment plants (WWTPs). The purpose of the guide is to provide information on how to reduce energy consumption in WWTPs, specifically through the maintenance and/or replacement of motors. Importantly, this guide answers the critical question of ‘when should a motor be rewound instead of replaced?’ The guide complements other work being undertaken by SAGEN on municipal energy management systems and energy management in WWTPs.

About: The Anaerobic Digestion Guideline is a practical guideline for wastewater practitioners and managers involved in the planning, design, operation, maintenance and management of WWTW. The guideline is based on the premise of the American “Capable Plant” concept which demonstrates a holistic management process for the beneficial use of biosolids and biogas naturally generated during the anaerobic digestion process. The Guideline will form the basis of a series of training and capacity building events for municipalities offered through WISA.

Disclaimer: The use of the Guideline is restricted to private use and may not be used for income generation purposes. Should any content be cited from the guideline, kindly acknowledge the authors and GIZ as publisher. The content of the guideline has been compiled by subject matter experts, peer reviewed by sector experts and tested during three pilot training sessions in municipalities.

GIZ-SAGEN supports capacity building measures to improve the operation and maintenance of municipal wastewater treatment plants, and to promote the use of generated biogas for power and heat applications. This fact sheet describes how a practical guideline i.e. the  "Anaerobic Digestion of Municipal Wastewater Sludge" was developed for this purpose, and piloted in three training sessions in order to test the concept and lend to the development of the guideline.

One of the key aspects in developing a biogas market in South Africa and understanding the full potential of the technology is unpacking the specific skill-sets required and job potential that the biogas industry holds. Therefore, the objective of this study was to explore in detail the employment potential from biogas along the main phases of a typical biogas project, as well as 4 categories of project sizes. The study also looked at the various skills and levels thereof needed for each project phase.
