Modelling of water supply system for the prospective factory of Coca-Cola company, Latvia

Abstract

A hydrogeological model (HM) has been created for checking sustainability of the water supply system of the prospective factory of the CocaCola Company. The Groundwater Vistas system was used, to run HM. HM covers the 9 km×10 km area located in the vicinity of the village Ropazi, Latvia. HM contains 11 layers, its plane ap proximation step is 20 metres. To estimate the water withdrawal impact on the groundwater body, the depression cones caused by the system were simulated for the Quaternary and Devonian type aquifers. The location and area of the chemical protection zone were found. Modelling has been performed, to find out that no worsening of water quality is expected due to considerable and durable groundwater discharge (4000 m3/day during 25 years) from the Devonian aquifer.
