In this paper the challenges in developing sustainable ASR operations in unconsolidated, low permeability aquifers, where operational problems such as well clogging tend to be more acute, are explored from the viewpoint of two case studies; one from Australia, the other from Thailand. Both studies were undertaken independently over different time-frames and brought together for comparative purposes. The Australian case study involved injection of wetland-treated urban stormwater into a low transmissivity, fine-grained siliceous aquifer; whereas the Thai case study involved injection of advanced-treated canal water into a colluvial/alluvial aquifer with high fines content. Although the design and execution pathways for the two trials were substantially different, ultimately the same endpoint (trial abandonment) was reached. This examination of the causative factors of failure, which were mainly related to poor recharge water quality for the Australian case, and poor hydraulic performance brought about by poor site selection for the Thai case study, lead to a number of key lessons being derived that could prove helpful to those considering ASR in similar environments.

Thailand’s naturally high seasonal endowment of water resources brings with it the regularly experienced problems associated with floods during the wet season and droughts during the dry season. Downstream-focused engineering solutions that address flooding are vital, but do not necessarily capture the potential for basin-scale improvements to water security, food production and livelihood enhancement. Managed aquifer recharge, typically applied to annual harvesting of wet season flows in dry climates, can also be applied to capture, store and recover episodic extreme flood events in humid environments. In the Chao Phraya River Basin it is estimated that surplus flows recorded downstream above a critical threshold could be harvested and recharged within the shallow alluvial aquifers in a distributed manner upstream of flood prone areas without significantly impacting existing large-medium storages or the Gulf and deltaic ecosystems. Capturing peak flows approximately 1 year in four by dedicating around 200 km2 of land to groundwater recharge would reduce the magnitude of flooding and socio-economic impacts and generate around USD 250 M/year in export earnings for smallholder rainfed farmers through dry season cash cropping without unduly compromising the demands of existing water users. It is proposed that farmers in upstream riparian zones be co-opted as flood harvesters and thus contribute to improved floodwater management through simple water management technologies that enable agricultural lands to be put to higher productive use. Local-scale site suitability and technical performance assessments along with revised governance structures would be required. It is expected that such an approach would also be applicable to other coastal-discharging basins in Thailand and potentially throughout the Asia region.
