The Shire of Peppermint Grove’s Grove library utilises a shallow geothermal system for heating and cooling.
The geothermal system comprises a production bore, an injection bore, several monitoring bores and associated above-ground infrastructure. About 4 L/s of water at 22 0C is extracted from the Superficial Aquifer for operation of the geothermal system.
Rockwater has developed a monitoring system that addresses both regulatory and operational requirements.
We established a remote telemetry system for the measurement of water levels in the production bore, the injection bore and one monitoring bore. Water levels in another monitoring bore and a decommissioned injection bore are measured manually.
This telemetry system includes titanium PT12 In-Situ loggers, non-vented Kevlar cabling and a YDOC adaptor that utilises the 4G network to record and store real-time, barometrically-corrected data on a remote database.
Since 2013, Rockwater’s involvement at Peppermint Grove has focussed on presenting cost-effective and practical solutions to support the system’s operation. Apart from the telemetry system, this has included redevelopment of the injection bore to improved is efficiency, and improvements to the particulate-filtration system.
We also prepare annual compliance reports for regulator.
