Erratum – [BIU V6.0.0 Wat 14] – Incorrect evidence requirements - KBCN1695
The criterion 3 evidence requirement, "evidence of monitoring data" is incorrect and invalid. Assessments should not try to meet this requirement.
Criterion 3 requires the water strategy to have senior management approval. This has no relation to monitoring water consumption, which is already addressed in Wat 13 Water consumption reporting.
This error will be addressed in future updates.
Using water from natural underground sources to offset water consumption - KBCN00094
Water from natural underground sources (for instance aquifer water accessed via boreholes) cannot be used to offset:
- NC / RFO: potable water consumption.
- IU: utility supplied water consumption.
A significant amount of water used for public consumption is already drawn from aquifers. Private boreholes may be drawing water from the same sources as public utility companies.
27-Mar-2024 - Title and text updated to broaden definition. Scheme applicability updated.
Water consumption reporting – Link to Man 04 - KBCN1611
The link to meeting compliance with Man 04, outlined in Wat 13 Criterion 1 is incorrect and should be disregarded.
Answer option D in Man 04 includes targets for Energy, Water and Waste. Whereas the intent of Wat 13 relates to targets for Water only. This will be updated in the next reissue of the technical manual.
Water strategy – Replacement and Schedule - KBCN1673
Replacement
The intent is that there is a programme in place which identifies any planned refurbishments and confirms that, where relevant, the works will include upgrading high water-consuming fittings and appliances with low water-consuming equivalents.
This does not require the systematic replacement of all fittings and appliances. However, it must also include a commitment to upgrading the efficiency of existing fittings and appliances when they reach the end of their service life.
Schedule
This may include specific fittings and appliances with low water consumption, or it can be based on a performance specification that these must meet, e.g. the flow rate or efficiency rating.
