Dear Customer of Yorkshire Water,

 

I refer to your request for information submitted to Yorkshire Water dated
10 August 2021.

 

Please find attached the data which you have requested.  Included with
this email are the response to your questions.

 

Yorkshire Water, in common with other water supply companies in England
and Wales, operates in accordance with a Water Supply Licence, as set out
in the Water Act 2014. The water industry is highly regulated at all
levels, including the use of chemicals and materials used in the treatment
and conveyance of potable water.

 

1. A full breakdown of the chemicals with % added to the water supply at
Yorkshire Water

 

The chemicals used by Yorkshire Water in the treatment of potable water is
proprietary information. Yorkshire Water treats water from a wide range of
sources, including rivers, impounding reservoirs and groundwater. These
require different types of treatment, dependent on water chemistry. All
chemicals used must conform with their respective BS EN standards and are
controlled by the regulator under Regulation 31 of The Water Supply (Water
Quality) Regulations 2016.

 

2. How often each chemical is added to the water supply at Yorkshire Water

 

Chemicals added during water treatment are typically dosed continuously
but the concentration varies dependent on the prevailing raw water
conditions, which can be highly variable.

3. Where the chemicals get added to the water supply

 

Chemicals are added at different stages of water treatment, according to
their intended mode of action. Some water treatment works are more complex
than others and these will typically dose a wider range of chemicals at
several treatment stages to achieve the required water quality. It should
be noted that some of the chemicals dosed are removed, at least partially,
during other treatment stages.

 

4. What PPE is worn by the Yorkshire Water member of staff - and why -
when handling these chemicals for application to the water supply.

 

Yorkshire Water operational staff are required to wear a minimum five
points of PPE (hard hat, hi-visibility jacket, eye protection, gloves,
safety boots) as part of the company’s H&S policy. Additional PPE may be
required in certain areas of a treatment facility and when undertaking
specific tasks. Water treatment chemicals used in treatment are dosed
automatically in a controlled manner.

I trust that the provision of this data satisfies your request.  In
accordance with the Environmental Information Regulations 2004, if you are
not satisfied with this reply to your request you can ask for an internal
review.  A request for an internal review must be submitted within 40
working days by contacting the Data Protection Team.

 

Thank you for contacting Yorkshire Water.

 

Yours sincerely,

 

Rebecca Dovener

Data Protection Team
