Groundwater Monitoring Wells Installation for Wairepo Arm Catchment Study

This procurement relates to the installation and development of three groundwater monitoring wells and a series of piezometers south of Lake Ruataniwha in the upper Waitaki as shown in Figure 1 and 2. These wells are to support investigation into understanding movement of water and nutrients within the Wairepo Arm catchment.

The proposal is to drill three wells, each 15-30 m deep with 150 mm steel casing and 2 m stainless steel screens, and; 8 piezometers, to be no more than 15 m deep. Final screen locations will be decided in consultation with the driller during construction based on the geology encountered. The project is also subject to time constraints. We require the contract to be completed by the end of June 2020.

Please ensure that you have the staff and availability to meet this deadline before submitting a tender. The wells are to be installed on private land. The Project Leader will confirm the exact site for installation of the wells with the drillers prior to mobilisation.
