Water and wastewater


If you believe that there is an increased risk of your suppliers discharging wastewater on a less responsible basis, and you wish to include this topic in the annex to your Code of Conduct, you can add the following requirements to your Code of Conduct by clicking on "Save to clipboard".

The shortage of water resources is expected to be exacerbated in many parts of the world as a consequence of various factors, including urbanisation and population growth, increased food production, industrialisation and climate change. Water pollution also affects how much water is available, and a wide range of a company's operations and activities involving water may generate wastewater.

Water and wastewater

a. The supplier has the necessary permits for wastewater discharges.

b. The supplier complies with any other legal requirements on wastewater discharges (e.g. certain standards and limit values for waste water discharges).

c. If treatment of wastewater takes places outside the supplier’s premises, the supplier demonstrates awareness of the effectiveness of the treatment.

d. The supplier documents a list or register of water consumption and wastewater discharges including content, type, limit value and quantity (e.g. over the past three years).

e. The sum of internal measurements is consistent with the bill paid to the water supplier and or wastewater treatment plant.

f. The supplier provides information on safe management of wastewater - including documentation of adequate training of employees who handle and manage wastewater.

g. The supplier keeps wastewater in closed systems before discharged.

h. The supplier does not have or cause any diffuse sources (not controlled) of wastewater discharge.

i. The supplier treats the wastewater before discharged to reduce adverse environmental impacts.

j. The supplier documents periodic wastewater analysis.

k. The supplier clearly attempts to prevent and reduce wastewater discharges through production efficiencies (e.g. waste water recycling, use of less harmful substances and reduction of the use of harmful substances).

l. There are no visible signs of untreated water discharges and associated pollution at and nearby the supplier’s facility.

m. The supplier’s sewage systems and storage facilities (if present) appear to be in a good condition.

A shortage of water and access to clean water are considered to be one of the greatest future environmental challenges, increasing in step with global population growth. The non-sustainable use of water resources may have significant adverse impacts on the natural environment. Suppliers should take account of the availability of water, especially in areas where water is in scarce supply, and should take measures to reduce their water consumption. Suppliers should also take measures to avoid water pollution by preventing and reducing their wastewater discharges, for example by increasing their production efficiency and phasing out hazardous substances. Wastewater must be treated in order to minimise adverse impacts on the aquatic environment.

The measures taken must be in accordance with national statutory requirements, international conventions, agreements, the precautionary principle and best practice.
