Avsallar is a small holiday town in Alanya region of southern Turkey and very popular for its long and beautiful sandy beaches.  Avsallar wastewater marine outfall design study was tendered in 1999 by Turkish Development Bank on behalf of the main client, Ministry of Tourism as a part of wastewater collection and treatment plant construction project.

Since it is located in such a popular tourism area and the discharge line had to cross the beach areas; it was very important to develop a design with zero water pollution risk.

The outfall pipe was designed as Ø 560 mm HDPE to discharge average wastewater volume of 15,000 m³/day. The length of the pipeline was determined to be 1260 m to make the discharge at 20 m depth.

All field surveys including bathymetrical, oceanographical, geotechnical and seismic were carried out by ARTI Proje besides the final engineering design of the outfall.
