Brain Perry Civil was awarded a Contract by Tauranga City Council to upgrade the local sewerage system.  This contract included the installation of 1550m of DN800 HDPE pipe by HDD under Tauranga Harbour connecting the sewerage pump system at Memorial Park to the existing sewerage lines at Matupihi. Lucas Engineering & Construction Pty Ltd was BPC’s SUBCONTRACTOR. Lucas’ scope of work was to install a 36” steel casing pipe using Horizontal Directional Drilling (HDD) into which the DN800 HDPE pipe would be installed upon completion.
