We have a strong commitment to sustainability and this is a key approach to the goods and services we buy. We aim to be a sustainable company with a sustainable supply chain.

Our procurement process sets the standards for each supplier to follow:


  • Assess and manage key environmental risks.
  • Comply with relevant environmental legislation, regulations and codes of practice.
  • Focus on waste reduction, recycling and the waste hierarchy.
  • Measure their carbon footprint and target reductions.
  • Think 'one planet'.
  • Have formal environmental management systems appropriate to their size. Larger companies are expected to be certified to ISO 14001 (or equivalent) by a certification body with IAF body member accreditation.


  • Be financially sound.
  • Operate a sustainable cost model providing a fair wage for employees and timely payment of suppliers.
  • Support an open book approach to cost, encouraging collaboration and driving sustainable cost reduction.
  • Maximise the benefit for the economy and employment in SWW's region.

Social and Ethical

  • Operate to the highest ethical standards.
  • Accept our Supplier Code of Conduct.
  • Comply with provisions of the Bribery Act 2010.
  • Declare any personal interests.
  • Comply with international labour standards in accordance with the principles of the International Labour Organisation Conventions.
  • Support sustainable local communities in their areas of activity.
  • Adopt appropriate ethical standards for global trading (ETI, SA 8000, UN Global Compact)
