Our client Tonkin Gap Alliance is constructing the Northern Dive as part of its METRONET Morley-Ellenbrook Line rail enabling works.

The Northern Dive requires dewatering of over 900,000kL during its construction. This required NPE to design the dewatering set-up to allow for the extraction water’s treatment and re-infiltration to protect the adjacent Banksia Woodland threatened ecological community (TEC) in accordance with environmental approvals.
