The Bowraville Off-River Storage Dam is a major, $38 Million water infrastructure project undertaken by HASLIN Constructions for the Nambucca Shire Council. The project was prompted 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 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.
“We are pleased and satisfied that the project met our community’s needs, was not subject to unacceptable or unexplained delays and was completed within Councils budget constraints.”
Rhonda Hoban, Nambucca Shire Mayor
“The $56 million project will secure the water supply of the entire Nambucca region and once full it will hold 4500 megalitres of water.”
ABC News, Monday 23rd February
“We had a budget of $54 million in 2007 dollars. The project came in at &56 million so if you take into account inflation at that time, it came in under budget. We were pleased with that outcome for such a project.”
Michael Coulter, Nambucca Council’s General Manager
