3.4.4 Requirements for water from any source

The requirements given under this section applies to water from an independent supplier (e.g. council or town supply) and water supplied by the operator for their own use (e.g. roof water, river water, water from a bore).

An operator who uses potable water supplied by an independent supplier without additional treatment only needs to comply with the requirements given in this section 3.4.4.

3.4.4.1 Management of reticulation system (i.e. reticulation management plan)

a. The water reticulation system within the premises must be designed, installed and operated in such a manner that prevents:

cross connections between potable and non-potable water;

stagnant water (i.e. no dead ends and unused pipes); and

back flow that may cause contamination of the water supply.

b. Water pipes, storage tanks and other parts of the reticulation system must be maintained in good condition.

c. The reticulation system must be flushed (i.e. taps are opened at point-of-use to allow a significant flow of water to occur) when water is not used for an extended period, and after any repairs to the system, to ensure that stagnant water, rust, scale and other material is flushed out of the system.

d. Operators involved in the seasonal extraction of honey or processing of other bee products must check and flush their reticulation system before pre-season cleaning is undertaken.

3.4.4.2 Procedures for non-complying water

All operations requiring the use of potable water must cease when:

the independent supplier (e.g. local council) advises the operator that the water is not fit for drinking without additional treatment, or the operator has reason to believe that the water is not fit for use, and the operator has no other means described in the risk management programme to ensure the water is potable at the point of use; or

if water used is supplied by the operator, and the operator fails to comply with any of the requirements of the water management plan (including corrective actions), and has no other means described in the risk management programme to ensure the water meets the original standard at the point of use.

3.4.4.3 Handling and disposition of contaminated materials

When contamination with non-potable water occurs, the following actions must be carried out:

affected edible bee product must not be used for human consumption;

affected product contact surfaces must be cleaned and sanitised prior to reuse; and

affected packaging materials that cannot be effectively cleaned and sanitised must not be used for packing of any edible bee product.

3.4.5 Additional requirements for water from an independent supply with additional treatment.

In addition to the requirements given in section 3.4.4 of this document, a water management plan must be documented and implemented for water from an independent supply with additional treatment. It must include:

information on any additional treatments (including type of treatment; parameters; procedures for control, monitoring/testing; acceptable limits);

a water sampling and testing programme for monitoring the effectiveness of the specific water treatment applied (as indicated in Table 2 or as necessary for the effective monitoring of any specific water treatment applied); and

corrective action procedures when the water source is found to be unsatisfactory based on the results of any test done.

Examples of additional treatment that may be applied by the operator for water from an independent supply (e.g. council or town supply) are: chlorination, ultraviolet treatment, heating and filtration. The operator should discuss with the supplier of the particular treatment, the types and frequency of water testing necessary to confirm the effectiveness of the treatment and ensure that it does not adversely affect the quality of the water (e.g. clogging of filters).

3.4.6 Additional requirements for water supplied by the operator for own use

3.4.6.1 Water management plan

In addition to the requirements given in section 3.4.4 of this document, a water management plan must be documented and implemented for water that is supplied by the operator for their own use. It must include:

an initial assessment of the water supply status by the operator by completing the Water Supply Assessment Checklist in Schedule 1 of the current version of the Animal Products (Specifications for Products Intended for Human Consumption) Notice;

Documenting a water management plan if required. This can be simply done by completion of a separate section D1 for each problem identified in the checklist which documents the identified problem and what is being done to manage it.

A copy of the Water Supply Assessment Checklist is available in Appendix 2, which is provided as a separate document to this Part for ease of downloading and use. This checklist is used to determine whether the water source is secure or satisfactory, and if additional treatment and/or other corrective action must be applied by the operator.

Guidance on ways to keep roof water safe is provided in Water Collection Tanks and Safe Household Water, Ministry of Health, August 1999 (code 10148). Guidance on protecting bore and well water is provided in Secure Ground Water (Bores and Wells) For Safe Household Water, Ministry of Health, March 2000 (code 1129). For more information on water safety and tank installation, read Household Water Supplies (code 4602), available from your local public health service or your local authority (council).

If you are concerned about your water supply, contact a Health Protection Officer at your local public health service or an Environment Health Officer at your local council. They will be able to recommend a local water testing laboratory.

3.4.6.2 Water sampling and testing

a. Potable water at the point of use must meet the criteria set out in Table 1. The minimum testing frequency required is given in Table 2.

b. Microbiological testing must be done by a LAS (Laboratory Accredited Scheme) laboratory registered for the required analysis, or a laboratory with persons who are accredited as signatories for the required analysis.

c. Water samplers must be trained by or receive instruction on how to correctly sample water from the laboratory selected.

d. Chlorine, pH and turbidity measurements must be performed by a suitably skilled person using documented methodologies (including calibration procedures) and/or calibrated equipment.

Table 2: Frequency of Testing

Operators with a secure water source are not required to test their water after the initial testing has been completed which confirms compliance with Table 1. All other water sources are subject to ongoing testing according to the frequency below.

Type of operation

Microbiological testing

Turbidity testing

pH testing (for chlorinated water)

Chlorine testing (for chlorinated water)

Honey extractors, packers and processors that operate on a seasonal basis (i.e. 0 - 6 months during the honey flow)

1 test per year done before the start of the
season *

1 test per year done before the start of the
season *

1 test per year done before the start of the
season *

Daily

Honey extractors, processors and packers that operate for 6 months or more

1 test per 6 months

* Water testing must be undertaken and acceptable results obtained before pre-season cleaning of the premises, facilities and equipment.

3.4.6.3 Reassessment of the status of operator supplied water

The potable water supply must be reassessed by operators who supply their own water by completing the Water Supply Assessment Checklist at least once every 3 years and within the time specified as follows:

in the case of a new source of water being used (that is, the source changes or a new source is added), the checklist is completed prior to use of the water; and

in the case of any changes to the environment on or around the water source that may affect the water quality, the checklist is completed within 1 month.

3.4.7 Monitoring

Compliance with these procedures must be regularly checked by the responsible person.

3.5 Records

Records containing the following information must be kept by the operator:

completed Water Supply Assessment Checklist (for operator supplied water)

water management plan, if applicable

water testing results, if applicable

observations from monitoring, any water treatment applied, and any corrective action taken.
