There must be a documented risk assessment for water use on the Safe Haven Assured production unit which covers all water used in seed or ware potato production, harvesting, packing, storage, transport, cleaning and disinfection of equipment and machinery, e.g. irrigation, mixing for fertilisers and PPPs.

How you will be measured

The Water Risk Assessment takes into account:

  • All sources of water used on the Safe Haven Assured production unit
  • Any water distribution and storage facilities.
  • All disease risks.
  • The Water Risk Assessment is reviewed at least annually or when risks change, e.g. when new land is rented.
  • An example decision tree to support the development of water risk assessment is detailed in Appendix 2.
  • Water Risk Assessment



Records must be kept of irrigation water usage.

How you will be measured

  • Date of usage
  • Water sources used
  • Water usage records
