Groundwater recharge through shallow groundwater recharge system by infiltration ponds in Fai Kwang Sub-district, Phayao Province of Thailand

Abstract

The shallow groundwater recharge at an area scale in Fai Kwang Subdistrict, Chiang Kham District, Phayao Province, Thailand aim to apply of the groundwater replenishment system to solve the problem of drought and insufficient water for consumption using by shallow groundwater recharge system through the concrete circle in pond integrating with using technology to manage surface water with the GIS system and geophysical surveys for evaluating the potential of groundwater resources to access information on land use, soil conditions, water resources. The groundwater recharge system at depth 12 m and water was replenishment occurs flow from pubic pool collected water converted to water filtration and pumping average water volume of 3.54 m3/hr to solve the problem of surface water quality for water supply in tap water production of Siwilai Village, Fai Kwang Subdistrict, Phayao Province, which enabled people in the area to used water for 200 homes. The social return on investment (SROI) was 59.23%, reducing water purchase and medical expenses due to water quality impact. The study results have led to the creation of water management policies and the application of information and innovations for drought resolution. Measures and requirements for using public water sources for consumption collecting income for the maintenance of the village's water supply system.
