Regulation 10 Category one supplies
For the purposes of this Part, a private supply is a category one supply if any water from the supply is supplied for domestic purposes and the supply is not a category two supply.
Subject to paragraph (3), category one supplies shall be divided into classes in accord ance with the following Table by reference to the number of persons supplied with water for domestic purposes and the relevant average daily volume of water supplied; but, if those factors would result in a supply falling into different classes, it shall be treated as falling into the class which is earlier in alphabetical sequence.
TABLE
| Class | Number of persons supplied with water for domestic purposes | Relevant average daily volume of water supplied in m3/day |
|---|---|---|
| A | >5,000 | >1,000 |
| B | 501 to 5,000 | 101 to 1,000 |
| C | 101 to 500 | 21 to 100 |
| D | 25 to 100 | 5 to 20 |
| E | <25 | <5 |
A category one supply which only serves a single dwelling shall be classified as a class F supply.
