Implementation and use of an automated monitoring system for wells production evaluation in occurrence region of serra geral aquifer system

This study was fulfilled in the city of Carlos Barbosa, located in northeastern Rio Grande do Sul state, which is supplied exclusively by groundwater from the Serra Geral Aquifer System (SASG). In this municipality it was installed an automated monitoring system, denominated SIGAS in 12 of the 15 wells that capture water from SASG and are used by CORSAN to the public water supply in the municipality. The SIGAS monitors volume, flow rate and pumping time 15 in 15 minutes and level of water in 1 in 1 minute. Were analyzed data collected in 3 wells 12 having the system. The data collected indicated that the 3 wells are working, in most of the monitored period, above the pumping time designed, operated with without pumping time discontinuously. The SIGAS proved to be a satisfactory system for monitoring wells, inserted in the Serra Geral Aquifer System and used for public supply, enabling the identification of the influence demand in the operation thereof, and the reflection of this operation we aquifer water levels well. Due to data collection frequency and easy access thereof by the managing body of the wells, the SIGAS shown to be an odd utility tool in the management of the wells.
