The Formosa Golf Club, located at Beachlands, south-east of Auckland, is an 18-hole championship golf course designed by national golf legend Sir Bob Charles.  The course includes a significant club house and adjoining luxury accommodation.  The club has its own private water supply for the needs of members and guests and for irrigating tees and greens.  A recent upgrade of the treatment plant to meet the new requirements of the DWSNZ 2005 (Revised 2018), was managed by GWE.

GWE was engaged to provide the following work: 

  • Bore Security Assessment to confirm their groundwater source is secure in accordance with Section 4.4 of DWSNZ 2005 (Rev 2018).
  • Catchment Sanitary Survey to understand the type, size and risk of the aquifer and its recharge zones.
  • Health Risk Management Plan.

GWE successfully prepared the WSP by implementing their in-house water source evaluation and treatment plant process auditing methodologies and health/risk management strategies.
