Abstract

Groundwater in the Sigi region of Central Sulawesi is used to meet the increasing needs of the community. The limited availability of groundwater caused by the earthquake in 2018 resulted in many wells in the area not produce optimally, while the community relies heavily on well water for the needs of the plantation business. Hydrogeological research in Sigi aims to determine the parameters of the aquifer and evaluate the performance of Wells. The method used is pumping test method in the form of step drowning test. Well test results showed an average transmissivity of 111.89 m2 / day[1] and storativity obtained an average value of 0.0095. The well condition is considered good with aquifer loss coefficient B values of 0.00501. Low well loss values C=0.000005 In the tests carried out, a small average value of B = 1.2 x 10-3 was obtained, so it can be concluded that the decrease in water level due to the linear loss factor is very small, this indicates that there is enough groundwater reserve in the aquifer but it should also be reviewed that this small decrease is due to the production capacity of the water flow in the well. The C value of 6 x 10-4 indicates that the decline that occurs around the well wall occurs slowly and the entry of aquifer constituent materials into the well that can cause damage to the well pump does not occur.
