F16(1)

In this Part, “monitoring of a Group A parameter” means monitoring of a Group A parameter for the purpose of obtaining information at regular intervals—

(a)

as to the organoleptic and microbiological quality of water;

(b)

where relevant, as to the effectiveness of drinking water treatment, particularly for the purposes of disinfection, for the purposes referred to in paragraph (2); and

(c)

as regards indicator parameters, whether water supplied for regulation 4(1) purposes meets the specifications for those parameters.

F16(2)

A Group A parameter must be monitored to determine whether its presence in water supplied for regulation 4(1) purposes satisfies the provisions of Part 3 or, if a departure has been authorised under Part 7 in relation to that supply, the provisions of Part 3 as read with the terms of that departure.

F16(3)

In this Part, “monitoring of a Group B parameter” means monitoring of a Group B parameter for the purpose of obtaining information from which it may be established whether water supplied for regulation 4(1) purposes—

satisfies the provisions of Part 3 or, if a departure has been authorised under Part 7 in relation to that supply, the provisions of Part 3 as read with the terms of that departure;

(b)

meets the specifications for indicator parameters;

(c)

in respect of other parameters identified as relevant by the Secretary of State under regulation 9, meets the specifications for those parameters.

(4)

This Part applies to water supplied for regulation 4(1) purposes by a relevant supplier in the performance of its duties under Chapter 3.

(5)

Regulations 6 to 10 apply to a F17wholesale licensee in relation to samples taken from supply points as they apply to a water undertaker, but only insofar as the F17wholesale licensee is introducing water into a water supply zone in which the water undertaker takes samples under this Part (to the extent authorised by or under regulation 8) from supply points.

F18(6)

In this regulation—

“Group A parameter” means a parameter specified in column 2 of Table 1 in Schedule 3;

“Group B parameter” means a parameter specified in column 2 of Table 2 or, as the case may be, Table 3 in Schedule 3.

Monitoring: general provisions6.

Paragraph (2) applies for the purpose of determining whether water to which this Part applies satisfies the provisions of Part 3 or, if a departure has been authorised under Part 7 in relation to that supply, those provisions as read with the terms of that authorisation.

(2)

A water undertaker must take or cause to be taken, and analyse or cause to be analysed, not less than the number of samples of the water within each of the water supply zones which it supplies specified in, or in accordance with the provisions of, this Part and Schedule 3.

F19(3)

Except in a case to which paragraph (16) applies, the parameters listed in Tables A and B in Schedule 1 and the indicator parameters must be subject to—

(a)

monitoring of a Group A parameter if the parameter is one listed in column 2 of Table 1 in Schedule 3 and the circumstances specified in column 3 of that Table apply;

(b)

monitoring of a Group B parameter in any other case.

(4)

In the application of paragraph (3)(b) to the aluminium, F20..., iron and manganese parameters (items 1, F219 and 10 in Table 1 in Schedule 3), a supply which consists of both groundwater and surface water is deemed to be a supply which consists only of surface water.

F22(5)

Compliance samples for chemical parameters including copper, lead and nickel must take the form of a random daytime sample of one litre volume taken at a consumer’s tap without prior flushing.

(6)

Paragraphs (7) to (15) apply to the radioactive parameters.

(7)

As regards the indicative dose parameter—

(a)

monitoring must be carried out where an artificial source of radionuclides or elevated natural radioactivity is present and it cannot be shown on the basis of other representative F23surveillance programmes or other investigations that the level of indicative dose is below the value specified in Schedule 2;

(b)

where monitoring for natural radionuclide levels is required, the Secretary of State must define the frequency of the monitoring of either gross alpha activity, gross beta activity or individual natural radionuclides, depending on the screening strategy adopted in accordance with Schedule 4;

(c)

where the monitoring frequency defined in accordance with sub-paragraph (b) requires one sample per year for naturally occurring radioactivity, a further sample must be taken where any change occurs in relation to the supply that is likely to influence the concentrations of radionuclides in water supplied for regulation 4(1) purposes;

(d)

in the case of naturally occurring radionuclides where the results of the monitoring referred to in sub-paragraph (b) show that the concentration of radionuclides in the supply is stable, the minimum sampling and analysis frequencies are to be decided by the Secretary of State and confirmed by notice to the water undertaker, taking into account the risk to human health;

(e)

a water undertaker may use a screening strategy for gross alpha, gross beta activity or individual radionuclides and, in the event that there is any exceedance of the value specified in Schedule 2, it must carry out an analysis of the specific radionuclides in accordance with Schedule 4.

(8)

As regards the radon parameter—

(a)

a water undertaker must ensure that a representative survey is carried out in accordance with paragraph (9) to determine the likelihood of a supply failing the parametric value for radon specified in Schedule 2;

(b)

monitoring must be carried out where there is reason to believe, on the basis of the results of the representative surveys or other reliable information, that the parametric value for radon might be exceeded.

(9)

A representative survey must be designed in such a way—

(i)

as to be capable of determining the scale and nature of likely exposures to radon in water intended for human consumption originating from different types of groundwater sources and wells in different geological areas;

(ii)

that the underlying parameters, in particular the geology and hydrology of the area, radioactivity of rock or soil, and well type, can be identified and used to direct further action to areas of likely high exposure.

(10)

As regards the tritium parameter—

(a)

monitoring must be carried out where an anthropogenic source of tritium or other artificial radionuclides is present within the catchment area and it cannot be shown on the basis of other surveillance programmes or investigations that the level of tritium is below the parametric value specified in Schedule 2;

(b)

if the concentration of tritium exceeds its parametric value, an investigation of the presence of other artificial radionuclides must be carried out.

(11)

Where a parametric value is exceeded in a particular sample, the Secretary of State must define the extent of re-sampling necessary to ensure that the measured values are representative of an average activity concentration for a full year.

(12)

The Secretary of State may notify a water undertaker which supplies water to a water supply zone that a radioactive parameter need not be monitored if the Secretary of State is satisfied that, for the period specified in the notice, the water supplied to that zone for regulation 4(1) purposes—

(a)

gives rise to a calculated indicative dose that is below the parametric value specified in Schedule 2,

(b)

contains levels of radon that are below the parametric value specified in Schedule 2,

(c)

contains levels of tritium that are below the parametric value specified in Schedule 2.

(13)

Where paragraph (12) applies, the Secretary of State must F24publish, in such manner as the Secretary of State considers appropriate, the grounds for the notification with the necessary documentation supporting the decision (including the findings of any surveys, monitoring or investigations carried out).

(14)

The Secretary of State must by notice in writing withdraw a notice under paragraph (12)—

(a)

given in relation to the indicative dose parameter, if the Secretary of State believes that water supplied to the zone in question for regulation 4(1) purposes gives rise to a calculated indicative dose that is likely to exceed the parametric value specified in Schedule 2;

(b)

given in relation to the radon parameter, if the Secretary of State believes that water supplied to the zone in question for regulation 4(1) purposes contains levels of radon that are likely to exceed the parametric value specified in Schedule 2;

(c)

given in relation to the tritium parameter, if the Secretary of State believes that water supplied to the zone in question for regulation 4(1) purposes contains levels of tritium that are likely to exceed the parametric value specified in Schedule 2.

(15)

A water undertaker which receives a notice under paragraph (14) must monitor or cause to be monitored the indicative dose parameter or, as the case may be, the radon or tritium parameter, in accordance with Tables F258 to 13 (as applicable) in Schedule 3.

(16)

Where the distribution of water in any part of a water supply zone is by tanker and is (or is likely to be) an intermittent short-term supply, samples of water from each tanker from which the water is distributed must be taken—

(a)

F26at the commencement of the distribution from that tanker, and

(b)

every 48 hours thereafter until the distribution is discontinued.

(17)

The first sample taken in relation to each distribution must be analysed for compliance with the following parameters—

(a)

E. coli (item 2 in Part II of Table A in Schedule 1), and

(b)

conductivity (item 6 in Schedule 2).

(18)

The second and any subsequent samples must be analysed for compliance with those and every other parameter.

(19)

On the coming into force of these Regulations, a notification under regulation 6(7) of the 2000 Regulations which had effect immediately before the coming into force of these Regulations is taken to be a notification under paragraph (12) of this regulation.

Sampling points7.

Except in relation to water supplied from a tanker, sampling points in respect of every parameter, other than a parameter for which samples are taken from a supply point authorised by or under regulation 8, must be selected at random unless, by notice in writing to a water undertaker (whether or not on the application of the undertaker), the Secretary of State otherwise determines.

Authorisation of supply points8.

(1)

For those parameters specified as F27item 6 in column 1 of Table 1, and as F28items 1 to 12 and 14 to 21 in column 1 of Table 3 in Schedule 3, samples may be taken from—

(a)

any blending point;

(b)

the water leaving any service reservoir which receives water from a treatment works before its supply to any consumer;

(c)

the water leaving any treatment works.

(2)

If the Secretary of State is satisfied that analysis of those samples will produce data which are unlikely to differ in any material respect from the data that would be produced from analysis within the sampling points, the Secretary of State may authorise the use for the purposes of regulation 6 of those samples taken for a water supply zone from a blending point, a service reservoir of that description or a treatment works.

(3)

In respect of any water supply zone, the taking of samples from a supply point is not authorised under paragraph (2) where a F29wholesale licensee introduces water into the water supply zone, unless the water quality within the water supply zone remains approximately uniform.

(4)

Subject to paragraph (6), the Secretary of State may, in relation to any parameter not covered by an authorisation given under paragraph (2), on the written application of a water undertaker or on the joint written application of a water undertaker and F30wholesale licensee, authorise the use for the purposes of regulation 6 of samples taken for a water supply zone otherwise than from a sampling point.

(5)

An authorisation under paragraph (4) may extend to all samples in relation to that parameter or to such number or proportion of those samples as is specified in the authorisation.

(6)

The Secretary of State must not grant an authorisation under paragraph (4) unless the Secretary of State is satisfied that analysis of samples taken from a point other than a sampling point will produce data in respect of the parameter in question which are unlikely to differ in any material respect from the data that would be produced in respect of that parameter from analysis of samples obtained from sampling points.

(7)

The Secretary of State may at any time vary or revoke an authorisation under paragraph (2) or (4).

(8)

But, unless it appears to the Secretary of State that the immediate modification or revocation of an authorisation under paragraph (4) is required in the interests of public health, the Secretary of State must give the water undertaker to which the authorisation relates at least 6 weeks' notice of the Secretary of State's intention to modify or revoke before making such modification or revocation.

(9)

A water undertaker must notify the Secretary of State as soon as it has reasonable grounds for believing that an analysis of samples taken for a water supply zone from a point other than a sampling point would produce data in respect of the parameter in question which would differ in a material respect from the data produced by an analysis of samples taken from any of the sampling points within that zone.

(10)

On being notified under paragraph (9) and without the need for prior notice to the water undertaker, the Secretary of State must revoke the authorisation under paragraph (4).

(11)

On the coming into force of these Regulations—

(a)

an authorisation under regulation 8(1) of the 2000 Regulations is taken to be an authorisation given under paragraph 8(2) of this regulation;

(b)

an authorisation under regulation 8(2) of the 2000 Regulation which had effect immediately before the coming into force of these Regulation is taken to be an authorisation under paragraph 8(4) of this regulation.

PART 8Water treatment

Disinfection and other treatment arrangements26.

(1)

Unless the conditions in paragraph (5) are satisfied, before supplying water for regulation 4(1) purposes, a water undertaker or F52wholesale licensee must—

(a)

disinfect the water, and

(b)

where necessary, subject the water to sufficient preliminary treatment to prepare it for disinfection.

(2)

A water undertaker or F53water supply licensee supplier must—

(a)

design, operate and maintain the disinfection process so as to keep disinfection by-products as low as possible without compromising the effectiveness of the disinfection, and

(b)

verify the effectiveness of the disinfection process.

(3)

Paragraph (4) applies when any property, organism or substance is present in a water source at a level that may constitute a potential danger to human health

(4)

Unless the conditions in paragraph (5) are satisfied, before supplying water for regulation 4(1) purposes using water from any source, a water undertaker or F52wholesale licensee must design and continuously operate an adequate treatment process for water from the source.

(5)

The conditions are that the water undertaker or F52wholesale licensee

(a)

must supply water from the treatment works as a matter of urgency in order to prevent an unexpected interruption in piped supply to consumers, and

(b)

before the supply is made, has taken all necessary steps to inform consumers that the water is not disinfected or adequately treated.

(6)

For the purposes of this regulation—

Risk assessment27.

(1)

This regulation applies to every treatment works and supply system from which water is supplied for regulation 4(1) purposes.

(2)

Every water undertaker or F52wholesale licensee must carry out a risk assessment of each of its treatment works and connected supply system in order to establish whether there is a significant risk of supplying water from those works or supply system that could constitute a potential danger to human health or is likely to be unwholesome.

(3)

Every water undertaker or F52wholesale licensee must keep its risk assessments under continuous review.

(4)

The Secretary of State may by notice served on a water undertaker or F52wholesale licensee require a risk assessment or review to be carried out by a date specified in the notice.

(5)

Where a water undertaker or F52wholesale licensee becomes aware of any factors which make it likely that a risk assessment under this regulation would establish that there is a significant risk of supplying water that would constitute a potential danger to human health or that is likely to be unwholesome, it must notify the Secretary of State specifying the relevant factors.

(6)

On the coming into force of these Regulations, a notice given under regulation 27(5) of the 2000 Regulations which had effect immediately before the coming into force of these Regulations is taken to be a notice given under paragraph (4) of this regulation.

Procedure following risk assessment and prohibition of supply28.

(1)

As soon as reasonably practicable after a water undertaker or F52wholesale licensee has carried out a risk assessment or review of such assessment under regulation 27, it must submit to the Secretary of State a report of the assessment or review.

(2)

The report must contain—

(a)

a description of the methods used to carry out the assessment or review;

(b)

where the assessment or review establishes that there is no significant risk of supplying water that could constitute a potential danger to human health or could be unwholesome, a statement confirming this;

(c)

where the assessment or review establishes that measures have been taken to remove a significant risk of supplying water that could constitute a potential danger to human health or be unwholesome—

(i)

monitoring data which verifies this;

(ii)

details of those measures.

(3)

Where the assessment or review establishes that there is a significant risk of supplying water that could constitute a potential danger to human health or could be unwholesome, the report must—

(a)

contain a full explanation including details of every property, organism or substance that has been identified as contributing to the risk;

(b)

specify the measures to mitigate the risk that the water undertaker or F52wholesale licensee

(i)

has made operational as at the date of the report, and

(ii)

intends to make operational.

(4)

Where the Secretary of State has received a report which states that there is or has been a significant risk of supplying water that could constitute a potential danger to human health or could be unwholesome, the Secretary of State may, by notice served on the water undertaker or F52wholesale licensee, require the water undertaker or F52wholesale licensee

(a)

to maintain such specified measures for such period of time as the Secretary of State considers appropriate to mitigate the risk;

(b)

to review, revise or make operational such specified measures by such date as the Secretary of State considers appropriate to mitigate the risk;

(c)

to audit whether the measures have been effective by such means as may be specified;

(5)

In paragraph (4), “specified” means specified in the notice served under that paragraph.

(6)

The Secretary of State may, by notice served on the relevant undertaker or F54water supply licensee, revoke or vary a notice served under paragraph (4).

(7)

On the coming into force of these Regulations, a notice given under regulation 28(4) of the 2000 Regulations which had effect immediately before the coming into force of these Regulations is taken to be a notice given under paragraph (4) of this regulation.

Water treatment to minimise contamination from pipes29.

(1)

Paragraph (2) applies where there is a risk (“the prescribed risk”) that water supplied by a relevant supplier would, for the reason mentioned in paragraph (3), after leaving the relevant supplier's pipes—

(a)

contain a concentration of copper in excess of 2mg/litre, or

(b)

contain a concentration of lead in excess of 10µg/litre.

(2)

Every water undertaker or F55wholesale licensee which introduces water into the supply system used by the relevant supplier must, subject to paragraph (4), treat the water in such a way as will, in its opinion, eliminate the prescribed risk or reduce it to a minimum.

(3)

The reason referred to in paragraph (1) is the presence in the water of a concentration of copper or lead which is attributable to the fact that copper or lead is the major component of such a pipe as is mentioned in section 68(3) of the Act M15, or its associated fittings.

(4)

Paragraph (1) does not require a water undertaker or F56wholesale licensee to treat water if—

(a)

the treatment is unlikely to achieve a significant reduction in the concentration of copper or lead, or

(b)

treatment is not reasonably practicable.

Replacement of lead pipes30.

(1)

The relevant supplier must modify or replace its part of the pipe where a relevant supplier—

(a)

has received from the owner of premises to which water is so supplied notice in writing of—

(i)

the owner's intention to replace so much of the pipe as belongs to him, and

(ii)

the owner's desire that the relevant supplier replaces the remainder of the pipe, and

(b)

has reason to believe that water supplied by it for regulation 4(1) purposes from a pipe to which paragraph (2) applies contains, or is likely to contain, at the consumer's tap, a concentration of lead which exceeds 10µg/litre.

(2)

This paragraph applies to a pipe—

(a)

of which the major component is lead,

(b)

which is subject to water pressure from a water main or would be so subject but for the closing of some valve, and

(c)

of which part belongs to a relevant supplier and of which the remainder belongs to the owner of any premises to which the relevant supplier supplies water for regulation 4(1) purposes.
