Article 4.2.2.3.1.

In a municipality for which the municipal zoning plan has been finalised, the discharge of industrial waste water containing no hazardous substances in the central area, the collectively optimised outlying area and/or the outlying area to be collectively optimised must satisfy the following general conditions:

1

the pH value of the industrial waste water discharged must be between 6 and 9.5;

2

the temperature of the industrial waste water discharged may not exceed 45C;

3

the dimensions of the suspended solids present in the industrial waste water discharged may not exceed 1 cm. These substances do not hinder the proper operation of the pumping and treatment stations by their structure;

4

the industrial waste water discharged does not contain any dissolved, flammable or explosive gases, or products that could cause such gases to be released. The industrial waste water discharged does not cause any dissemination of effluvia that harm the environment;

5

the following concentrations may not be exceeded in the discharged industrial waste water:

a)

1 g/l suspended solids;

b)

0.5 g/l substances extractable in petroleum ether.

6

unless explicitly provided for in the licence, the industrial waste water discharged may not contain substances that:

a)

constitute a hazard for the maintenance personnel of the sewer system and water treatment installation;

b)

may damage or block the pipes;

c)

constitute an impediment to the proper working of the pumping and water treatment units;

d)

may cause serious pollution of the receiving surface water or may seriously pollute the receiving surface water in which the water from the public sewer is discharged;

7

assessment of the discharge of industrial waste water at a sewage treatment installation is governed by the criteria stated in Articles 2 and 3 of the Order of the Government of Flanders of 21 February 2014 establishing the rules for the discharge of industrial waste water at a public sewage treatment installation.
