Purpose and goal
In this prestudy the aim was to get an overview of the Vomb field and the Vomb waterwork through model studies and analysis of data. The result should be the basis for optimizations of how to operate the pumps in the field. Incorrect operation of the pumps leads to increasing costs for maintencance and running and with the risk of getting poor water quality. The pumps are today operated according to an older scheme and it´s wellknown that it´s not optimal. Simple dynamic models of the field were set up based on data to estimate how the demand of the consumers varies and affects the waterwork.
Results and expected effects
The result of the prestudy is a good basis for continued modelling studies, simulation and prediction both in the Vomb waterwork and the Vomb field. When more data is digitally logged from the field will give more possibilities to improve and validate the model and create a control system for the operation of the pumps.
Approach and implementation
The prestudy consisted of four activities: 1.Raw data analysis from the field: Interesting results about the profile of the groundwater and the yearly variation was found. 2.Modelling of the groundwater in the field: A model for the groundwater was implemented and compared to data. Knowledge about lacking data was gained. 3.Raw data analysis in the waterwork: The analysis went as planned, the daily variations were studied and extreme cases identified. 4.Modelling of the waterwork: Simple models for the dynamics in the waterwork was simulated and in surprisingly good agreement.
