The Requirement: Prior to the start of construction monitoring of water quality to assess the impact of turbidity on a nearby water supply.
Solution: Deployment of a vanwaltDataHub and vanwaltDataSlaves, attached to single parameter water quality sensors to monitor turbidity levels with data collected every 15 minutes and uploaded hourly, directly to the regulator and other interested parties.
The Requirement: Part of the infrastructure is below the water level and could be subject to flooding. Dewatering pumps on the adjacent properties exacerbates the problem.
Solution: A number of Van Walt Data Collection Systems monitor the water levels. Alarms have been set so all parties receive an early warning that flooding could occur.
The Requirement: Flow rate of streams determine water abstraction permissions to the ski field operator who requires water for snow making. The regulator requires daily data.
Solution: Flumes are installed to derive water flow data. Using the alarms functionality a water pump is either switched on or off. Data is automatically forwarded to the regulator by FTP. A similar system is also used to switch off the pumps when the turbidity is too high and could damage the pumps.
The Requirement: Large sluice gates between lake and river affect the level of the adjacent river when they are opened. The regulator wishes to establish the effect.
Solution: Installation to record data every 5 seconds with an accuracy better than 5mm. Uploads every 30 minutes to our server and daily transfer of data by FTP to the regulator.
