Ground Water

 

Water catchment

It is important to supervise and control the catchment of our groundwater, in particular because water catchment influences on the groundwater resources and the environment. Catchment of groundwater resources is first and foremost used to supply the population with drinking water according to the EU standard, but also within a number of different industries you can obtain permission to have your own drilled well and water supply.

The production of drinking water from these plants are controlled and surveyed by different automatic systems. The control considers both the operational production as well as the demands on quality and quantity for clean drinking water. These years it is often seen that smaller neighbour waterworks are joining together in a network in order to be able to control and survey from an overall control system.

 

Control

Kemic Water Technology offers a number of adapted systems for supervision and data collection from the waterworks. The control includes both catchment of water from the bore wells, filter plant and clean water pumps and water tanks for storage of the clean water. The control systems are operated by PDA either via GPRS on mobile phones or various data- and ADSL systems from which data can be transferred directly from the waterworks to the connected customers computers. The control system can also handle different types of alarms, such as alarms with locking devices on each bore well, signal for level indicators in the bore wells or pressure drop. The UPS back-up system can be integrated in the control system. Collected data is integrated in the reporting system and indicated as graphs.

 

The Process

The water catchment can be controlled by a fixed level in the clean water tank in relation to different requested values or according to adjusted time schedules during the day. This gives the opportunity to vary the requested water quantity in the tank and thereby utilize the buffer capacity of the tank during the day. This ensures a steady production as well as protection of the catchment area. Everything is controlled directly from the computer which is connected to the SRO/SCADA system. The system can also be connected to Kemic Water Technology, who will follow the operation of the plant, consult and assist in troubleshooting.

 

Raw water analysis

Raw water analysis and demands on the cleaning ability are crucial for the capacity and purifying process for each plant. Often the so called Ochre, which is the content of iron and manganese in the water, is an important reason for mounting a filtering system. This is why a thorough knowledge of the capacity need and water analyses are very important when a plant is being established.
