Constructed and riverine wetlands design considerations for domestic and agricultural diffuse pollution treatment—a case study from Turkey

AbstractIn this study, a riverine constructed wetland system (RCWS) was monitored with the aim to investigate its functionality and cost-effectiveness in treating domestic wastewater. Turkey’s second biggest freshwater lake, Egirdir lake, is becoming polluted directly and indirectly with both domestic and diffuse pollution sources. In this paper we: (1) describe a water quality monitoring campaign on an existing long drainage channel where the majority of pollution originates from untreated urban sewage (2) discuss the design parameters and some considerations for a new RCWS to diminish and eliminate domestic and diffuse pollution loads originating from Gelendost and Yaka. In our design considerations, (1) we projected population increase over a 30-year period, which resulted in total 12,000 population equivalent, including the drainage network run-off originating from agriculture; (2) we aim to achieve 90% reduction in chemical oxygen demand, 70% of nitrogen (N) and 40% of total phosphorus. To achieve de...

Large scale constructed wetland implementation projects in Turkey in Salt Lake Special Environmental Protection Area

Abstract Salt Lake, in ecological and economical terms, is one of the most important lakes in Turkey. The lake exhibits great biodiversity of plants because the lake and its basin are a natural habitat to various types of endemic plants which are resistant to a salty environment. The lake also serves as a habitat to many kinds of birds, especially flamingos. From an economic standpoint, Salt Lake meets approximately 70% of the salt requirement for Turkey. For this reason it is of great importance to preserve the natural environment of the lake. In addition to the various activities conducted for the environmental protection of the Salt Lake, a comprehensive constructed wetland (CW) project has been prepared and implemented for the towns of Sultanhani and Altinekin, where the population is expected to reach approximately 5000 by the year 2037. It entails the largest and most important subsurface-flow constructed wetland systems(CWs) in Turkey. Many site surveying research projects have also been conducted ...

Development of National Action Plan to Address Pollution from Land Based Activities in Turkey

Countries surrounding the Mediterranean Sea and Black Sea signed the Barcelona Convention (1976) and Bucharest Convention (1992) respectively and Turkey is the one of the contracting parties for both of them. In this content, they formed the “Mediterranean Action Plan (MAP)” and “Black Sea Environment Programme” to control water pollution in the Mediterranean and Black Sea, respectively. To achieve this goal, each region formed their Land Based Sources Strategic Action Programme (LBS SAP) in the second part of the 1990s within the framework of the Land Based Sources Protocols (LBS Protocol) which are sub protocols of the Barcelona Convention and Bucharest Convention. These programmes define the major land based environmental problems and proposed solutions to the problems and set the deadlines to perform the necessary tasks. In the line with LBS SAP’s, Mediterranean countries have been already developed their “National Action Plan’s for Land Based Sources (LBS NAP) in 2005.
