Lokal Water Sensitive Urban Design (WSUD Systems) with BIO-BLOK® drywell

Local Rainwater Harvesting

Rainwater is a valuable recourse and with relatively simple methods using the BIO-BLOK® rainwater drywell, the rain water can be channeled back into a natural water cycle. The principle is called water sensitive urban design (WSUD), contact us for further information about this sustainable solution.



Spreadsheet for calculation

EXPO-NET has developed an Excel Spreadsheet for calculating the dimensioning of BIO-BLOK® rain water drywells. The Excel Spreadsheet can calculate the use of BIO-BLOK® elements for five different types of soil - coarse sand, fine sand, silt, sandy clay and silty clay.

The Excel Spreadsheet is available for download by clicking on the link. It is a good idea to save the Excel Spreadsheet before use.

The calculations are in accordance with Publication no 25 of the Danish Wastewater Committee. The values of 10-7 m/sec. are estimated by extending the current charts.

The drywells are dimensioned on the basis of an expected overload of maximum once per year (T = 1 year).

Before you open the Excel Spreadsheet for the first time you must ensure that the security settings in Excel are correct.

The Security Level must be set at "Medium". This can be done by opening the Excel application, the go to "Tools" in the main menu, select "Options" and go to the "Security" tab - click on the "Macro Security" button and under the "Security Level" tab, select "Medium".

The Excel Spreadsheet ca not be opened. Remember that you must open the Excel Spreadsheet "With Macros" in order to activate the formulae that perform the calculations. 

We draw your attention to the fact that use of the Excel Spreadsheet is at your own risk.
