Anaerobic Digestion of Municipal Wastewater Sludge: A Practical Guideline

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.

Fact Sheet: Generating biogas from the digestion of municipal wastewater sludge

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.

Household Energy Baseline Study and Community Facilitation for the Installation of Solar Water Heaters in Walmer and Rosedale, Port Elizabeth

The aim of consultancy was to collect baseline data regarding household socio-economic profiles, energy consumption patterns, current levels of household knowledge regarding SWH and the willingness of the community to be beneficiaries of the SWH systems. The objective was to indicate cost and energy savings calculations after the installation of the SWH, and to develop a community consultation and communication programme that will outline the required steps to ensure the success implemented at the Nelson Mandela Bay Municipality pilot-project.

Review of Best Practice of SWH Implemented by Local Government

The purpose of the review was to determine the best practice of SWH implemented by selected municipalities that previously in the Eskom Rebate Programme (eThekwini, City of Cape Town, Sedibeng, and Musina). The review explored the roll-out experience from a municipal perspective, considered the process from pre- and post- installation, with an intention to enhance future implementation of NSWHP.
