The project scope forms part of the overall drainage design to cover the township of Morven.

Brownrigg Street Drainage Stages 2 and 3 involves the construction of piped drainage as well as associated pits and open swale drains. The previous Stage 1 piped system discharges to the creek forming the main outfall for the township. Stages 2 and 3 continue north along Brownrigg Street towards the Culcairn Holbrook Road.

Each property is to be provided with a 150mm house drain and a 600mm diameter 900mm deep grated CPO pit or similar.

Future stages will include the continuation of the works along a number of side streets.
