Artificial Recharge of the Heretaunga Plains Aquifer Hawke's Bay, New Zealand

by P. "Takis" Koutsos, Hawke's Bay Catchment Board, New Zealand,



Document Type: Proceeding Paper

Part of: Artificial Recharge of Ground Water

Abstract:

The Heretaunga Plains groundwater system in the Hawke's Bay region of New Zealand, is naturally recharged from the nearby Ngaruroro River at the approximate rate of 5.5m³/sec. It is an artesian aquifer which supplies most of the domestic, irrigation and industrial needs to a community of 120,000 people. The recharge site is over an unconfined part of the aquifer and the water is introduced by means of four shallow infiltration ponds. The design of the system incorporates a sedimentation pond, electric fish barrier to prevent stranding of fish in the infiltration ponds and automatic control of the intake sluice gate which is activated by a pre-set upper limit of suspended sediment in the recharge water. This paper covers the design of the artificial recharge system, the monitoring of its performance and the evaluation of its effectiveness.
