It was designed by Sewerage Construction Branch and NSW Department of Public Works and built during 1895 by J. F. Carson, contractor.

The line extended from the Rockdale end of the Arncliffe sewerage farm (which was enlarged for the scheme) to the sewer penstock at Premier Street, Marrickville.

The sewer carrier emerges from the brick faced northern abutment below Thornley Street, Marrickville crossing the river by the steel trusses and then continuing further across the river and Wanstead Reserve by brick arches to embankment at the end of Wanstead Avenue, Undercliffe.

[1] As at 21 April 2005, the Cooks River Valley sewage aqueduct, completed in 1895, was an integral and highly visible component of the original Main Western Carrier (now part of Southern and Western Suburbs Ocean Outfall Sewer System), which was one of the Board's major early sewerage schemes.

The two original sewer carriers are likely to be rare examples of large diameter, long run wrought iron pipes used for such a purpose.

Elements of significance are past and ongoing use, construction technologies and setting with the Cooks River valley (inclusive of views).
