Table of waste water coefficients

The table of waste water coefficients is part of the Delfland Purification Levy Regulation (appendix II) and the Schieland and Krimpenerwaard Purification Levy Regulation (appendix II).

Below are the waste water coefficient table and the waste water coefficient conversion table. The conversion table shows which business units fall into which class of the waste water coefficient table. Look up the industry of your business activities and read from the table which class and coefficient applies to your company. The waste water coefficient is a number. This number is multiplied by the water use. The result is the number of pollution units.

Waste water from the personal care of employees working in the premises or parts of premises marked with an * in this table 0.023 klasse 8

*) Is the amount of water used for personal care not measured separately with a
dedicated water meter? Then the assumed consumption is set at 11 m3 per full-time employee. The total amount of waste water for personal care is then calculated by multiplying the number of employees by 11 m3.

**) A separate intermediate meter must be present for this business unit.
