Overview

This procurement relates to the installation and development of three groundwater monitoring wells at Teschemaker Valley Road, around the location shown in Figure 1 and 2 below. As part of Environment Canterbury’s responsibilities, we monitor groundwater at locations throughout the region. Each year we aim to install new monitoring wells to enhance our monitoring network. This year, we plan to install a cluster of wells at different depths in the Makikihi area.
The proposal is to drill three wells, around 15-20 m, 50 m and 120 – 150 m deep with 150mm steel casing and 2m stainless steel screens. The final screen locations will be decided in consultation with the driller during construction based on the geology encountered. Previous drilling in the wider area has highlighted the potential for sandy, sometimes ‘heaving’ formations which may require special consideration for drilling and screening.
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 Project Leader will confirm the exact site for installation of the wells with the drillers prior to mobilisation.
