TankCheck™ focuses on a preventative approach to minimise the risk of contamination of soil, and ground and surface waters. The objectives of TankCheck™ is to to provide a mechanism to ensure early detection of leaks from UPSS.
In line with the UPSS Regulation, TankChecks aim is to promote the adoption of industry best practice in ongoing operation of underground tanks used to store petroleum, both as fuel or as used (waste) oil.
The UPSS Regulation, which commenced on 1 June 2008, may be viewed at www.environment.nsw.gov.au
The Daily Inventory Sheet is where you record all dips and meter readings.
Select the Daily Inventory Sheet by clicking on the 'Daily Measurements' tab at the top of the window.
There are 3 main parts to this screen.
- General Information about when the dips and readings occurs (Date and Time), who the reading was entered by, and any day notes about this reading.
- Pump Readings - these are where the total meter readings on each pump is entered. The Pump meter readings are used to automatically calculate the difference between the last reading and the current one. This is to allow quick identification of problems, both with the pump and data entry.
- Tank Readings - This is where the tank dip and water readings are entered. The dips give an indication of the actual volume of fuel contained in the tank at any point in time.
The Deliveries form is for recording deliveries of fuel made to the site. These records are used in the reconciliation calculations.
When the delivery happens, enter the following information for each tank
- The dip reading before delivery
- The dip reading after delivery
- The volume from the delivery docket.
TankCheck™ will calculate the dip delivery volume, so you can verify the docket is correct. After the data is entered, click the 'Add this record to the set' button to add this record to the database.
This software is only as good as the data entered! Because it does calculations based on days when sales occurred, if you skip data entry for a day when there was output from the tank or enter incorect values, the calculations will be off!
To help identify these problems your records can be presented in charts to easily see the health of your UPSS.
With the recent addition of charts displaying; Dip, Delivery, Sales and unaccounted variances, trouble shooting data entry errors has been made much simpler.
For demonstration purposes, three trouble shooting scenarios are presented below with the support of charts to quickly identify and explain the error;
Using the chart, unaccounted Tank Loss or Gain (Yellow) will indicate problems in the data. In this example where greatest unaccounted gain and loss is, there is a corresponding error in the dip readings to be reviewed.
Double Delivery Error
In this error, there looks to be a double deliery (Green) causing an unaccounted gain in the tank (though hard to see).
