The 70 years old Langa Interceptor Sewer, which drains the Langa residential area, is one of only a handful of known egg-shaped sewers in the Cape Town metropolitan area. Since the mid-1980s severe siltation has been reported in the sewer, which has required regular intensive mechanical (bucketing) cleaning. When the 510 m long sewer, which traverses a traditional initiation site for approximately 300 m, started experiencing regular structural failures, the City of Cape Town (CCT) appointed AECOM SA (Pty) Ltd to construct a sand trap and rehabilitate the sewer. The first phase of the project was completed in 2009 with the construction of the sand trap in an upstream position outside the initiation site boundaries.
