CLIENT: Carlors Services Ltd
The aim of this study was the hydrogeological analysis of the Agros Bottling Plant area, in order to assess the sustainable yield of two existing boreholes in the study area. The intention of the Client was the increase of the annual groundwater abstraction from 29,000m3 to 45,000m3. The analysis was based on a 24-hour pumping test and the aquifer characteristics, as well as the meteorological, hydrological, hydraulic, hydrogeological and geological conditions in the current region, using various methods found in literature (e.g. «Cooper-Jacob» method, «Aquifer Win» software etc.). The nearest meteorological stations were the Agros Meteorological station «M.S 377» and the Platania Meteorological Station «M.S. 310», while the area was mostly being characterized as a member of the ophiolitic site of Cyprus. According to the analysis of the results, the assessment of the sustainable yield of each borehole was estimated.
The tasks that were successfully completed and the services that were provided were:
- The performance of a 24-hour pumping test, using one pumping well and two observation wells,
- The analysis of the results of the 24-hour pumping test,
- The analysis of the current state of environment, based on the available meteorological, hydrological, hydraulic, hydrogeological and geological data.
Based on the results’ analysis, in order to maintain the groundwater level in sustainable and acceptable levels, the daily pumping quantities were estimated in 350m3/day for W131/93 and 320m3/h for W52/77, equal to 11 hours of pumping per day for W131/93 (32m3/h) and 9 hours of pumping per day for W52/77 (37m3/h). Taking into consideration all the uncertainties and the assumptions made, and based on the fact that groundwater enrichment occurs directly from rainfall, the increase of the annual groundwater abstraction from 29,000m3 to 45,000m3 is possible.
