Download ▶︎ Planning Service ▶︎ Greywater Reuse


You can estimate the expected grey water production and service water requirement for your project here. The calculation is based on the standard values for the respective building type.

If you send us the information via ‘Send’, we will submit a proposal for your optimum grey water utilisation system. This will take into account the demand, the grey water yield and the expected amount of grey water and service water consumption on a daily basis.

Your data will only be used to process this one project; if you would like to be informed 1-2 times a year about news from DEHOUST, please agree accordingly.
