Water quality standards across the world are being re-written to promote healthier ecosystems, ensure safe potable water sources, increased biodiversity, and enhanced ecological functions. Treatment wetlands are used for treating a variety of pollutant waters, including municipal wastewater, agricultural and urban runoff, industrial effluents, and combined sewer overflows, among others. Treatment wetlands are particularly well-suited for sustainable water management because they can cope with variable influent loads, can be constructed of local materials, have low operations and maintenance requirements compared to other treatment technologies, and they can provide additional ecosystem services. The technology has been successfully implemented in both developed and developing countries.
The first IWA Scientific and Technical Report (STR) on Wetland Technology was published in 2000. With the exponential development of the technology since then, the generation of a new STR was facilitated by the IWA Task Group on Mainstreaming Wetland Technology. This STR was conceptualized and written by leading experts in the field. The new report presents the latest technology applications within an innovative planning framework of multi-purpose wetland design. It also includes practical design information collected from over twenty years of experience from practitioners and academics, covering experiments at laboratory and pilot-scale up to full-scale applications.
Scientific and Technical Report No.27
Constructed Wetlands for Pollution Control
The book presents a comprehensive up-to-date survey of wetland design techniques and operational experience from treatment wetlands.
This book is the first and only global synthesis of...
River Water Quality Model No.1
This Scientific and Technical Report (STR) presents the findings of the IWA Task Group on River Water Quality Modelling (RWQM) in a critical evaluation of the current state of the practice in...
Benchmarking of Control Strategies for Wastewater Treatment Plants
Wastewater treatment plants are large non-linear systems subject to large perturbations in wastewater flow rate, load and composition. Nevertheless these plants have to be operated continuously,...
Generalised Physicochemical Model No. 1 (PCM1) for Water and Wastewater Treatment
This book describes theory and approach for a comprehensive and applied physicochemical model for wastewater treatment. These are reactions which occur without a biological mediator, and are...
Water in Himalayan Towns: Lessons for Adaptive Water Governance
Increasing urbanization and changing climate are two critical stressors that are adversely affecting the biophysical environment of urban areas in the Hindu Kush Himalaya. The book discusses...
Sustainable Treatment and Reuse of Municipal Wastewater
In many countries, especially in developing countries, many people are lacking access to water and sanitation services and this inadequate service is the main cause of diseases...
Membrane based Point-of-Use Drinking Water Treatment System
Membrane based PoU water treatment systems are preferred due to shortcomings of other water treatment technologies. This system works without the addition of chemicals, with relatively low energy...
Hydrological Design of Multipurpose Micro-catchment Rainwater Management
Rainwater as a resource has been underrated due to scientific misunderstandings about its quality, the lack of hydrologic design tools for small catchments, such as roofs, the preference for large...
