How Treatment Technologies Impact the Climate

Two e-Learning courses took place in 2018. The content of the courses (8 Modules in total) can be downloaded for free from this page.


Jordan experiences negative impacts imposed by climate change. 63% of Jordan’s population are currently served by public sewer networks. The expansion of the public sewage system into the unserved areas is not mainly hindered by financial limitations but also the topography as well as fragmentation of the settlements. There is a promising potential for Jordan to adopt decentralized approaches in wastewater management

But what are really these decentralized approaches? How do they work, what are the technologies used, operation and maintenance requirements? Are there any existing examples to learn from?

Two E-learning courses («Basics of Wastewater» and «How Treatment Technologies Impact the Climate») gave answers to the many questions on Decentralized Wastewater Management (DWWM) in Jordan in a participative, learner-centered and practice-oriented way.

The content of the courses has been developed on behalf of the ACC-project (implemented by GIZ-Jordan) mainly by Hans Hartung (Margraf Publishers GmbH) and Sophia von Dobschuetz (Borda WesCA). On this page, we give you the opportunity to browse through the whole content of the courses and to look at the video recordings of the eight webinars which took place during the trainings:

«INTRODUCTION & BACKGROUND»: Priority of module I is the understanding of wastewater and the different characteristics. To be able to understand why wastewater has to be treated, the historical evolution, the different views and the opinions on the various treatment approaches have to be examined. Module I consists of four lessons. Click here to download the PDF ›››


«WASTEWATER MANAGEMENT»: The module II is designed as an introduction to wastewater management with an emphasis on sustainable decentralized approaches. Basic concepts of planning sanitation systems in a participative way are presented as well as an overview of climate change and how it affects wastewater collection and treatment. Module II consists of four lessons. Click here to download the PDF ›››


«INTERFACE, COLLECTION & CONVEYANCE»: Module III presents technologies for user interfaces, for collecting and transporting fecal products from the point of origin to the site where they are treated. Different systems for treatment exist that are dealt with in this module, which consists of three lessons. Click here to download the PDF ›››


«WASTEWATER TREATMENT TECHNOLOGIES»: In this module IV, treatment technologies will be introduced. The focus will be on treatment technologies used in the ACC project, but other technologies will also be presented with its advantages and disadvantages and how they are designed and implemented. Module IV consists of three lessons. Click here to download the PDF ›››


«SLUDGE TREATMENT»: In module V, sludge and the different possibilities of treating it are presented. Unfortunately, sludge as one end-product in wastewater treatment plants is often neglected and not taken with the emphasis it deserves. This module therefore highlights the importance of the different sludge treatment technologies and gives an overview on how they can be used to result in a safe and useful product. Module V consists of three lessons. Click here to download the PDF ›››


«OPERATION & MAINTENANCE»: Specific operation and maintenance considerations have been given for the technologies described in modules 3, 4 and 5. In this module, more generic issues for operation and maintenance (O&M) are highlighted, mainly concerning its management. Public health and occupational safety procedures for the operation and maintenance are dealt with. The Standard Operation Procedures (SOP) of the Jordanian Ministry of Water and Irrigation (MWI) concerning wastewater treatment plants are referred to. Module VI consists of two lessons.

«RE-USE OF WASTEWATER & SLUDGE»: Wastewater treatment processes produce certain end-products which can be reused in different ways. This module explains technical solutions and legal as well as social restrictions for a reuse. Module VII consists of two lessons. Click here to download the PDF ›››


«ADAPTATION TO CLIMATE CHANGE IN JORDAN»: This module explains the concepts of mitigation and adaptation. Technologies with lower dependence on water supply, which is true for specific wastewater treatment technologies, are expected to have greater resilience to climate change. By using reuse-oriented sanitation systems with energy, nutrient or wastewater recovery and reuse, anthropogenic greenhouse gas emissions can be reduced (mitigation) as well as people's capacity to cope with climate change impacts can be increased (adaptation).  Module VIII consists of two lessons.
