The Bowraville Off-River Storage Dam was necessitated by the lack of water certainty in the Nambucca region, and included construction of a zoned, clay-core dam with chimney and blanket filters, plus 500 000m3 of embankment works complete with rip rap protection.

A concrete encased, 900 dia outlet pipe was built in the foundations, and this is serviced by a 27m high intake tower complete with access bridge. The spillway consists of approximately 5000m3 of reinforced concrete. Access to the site comes courtesy of a 2.5km, dual carriageway road, also constructed by HASLIN.

This dam has guaranteed the Nambucca Shire’s water supply for generations to come, and further solidified Haslin’s reputation for providing major state water infrastructure.
