Work at Advanced Drainage Systems (ADS) isn''t going down the drain, it is the drain. ADS makes high-density polyethylene (HDPE) pipe for storm and sanitary sewers, agricultural drainage, road and highway construction, and residential and commercial development.
These drainage systems are often surface drainage, and do not perform well. Better systems are underground pipe drainage at a depth of about 1 m, and these are being introduced in some areas. Land in the second Euphrates terrace, near Rakka, was brought under irrigation in the 1970s, and a survey undertaken in 1980 showed that severe salinization had occurred in about 24 percent of the area.
Local salinization mechanisms are suggested, i.e. the upwelling of saline water from the underlying, confined Continental Intercalaire (CI) aquifer, as well as backflow of agricultural drainage water.
