The Water Supply (Water Fittings) Regulations 1999
• My name is Michael Dean
• I work in the Water Regulations Department.
• We will be presenting an overview of the above regulations and
specifically how they apply at Allotments.
• Regulations are a very large topic and we will only cover how they
apply at Allotments unless you have any other questions.
• Questions are welcomed at any time.
Welcome
![Page 3: Water Regulations for Allotment Users 1999 onwards](https://reader035.vdocuments.mx/reader035/viewer/2022081417/56649d8c5503460f94a73704/html5/thumbnails/3.jpg)
The Water Supply (Water Fittings) Regulations 1999
• Water Suppliers are known as Water Undertakers.
• We undertake to supply you with drinking quality water.
• This is what the ‘Water Supply (Water Fittings) Regulations are
intended to ensure.
• Our objective (unlike our namesake) is to keep you fit and healthy
by providing you with good quality drinking water.
What is a Water Undertaker
![Page 4: Water Regulations for Allotment Users 1999 onwards](https://reader035.vdocuments.mx/reader035/viewer/2022081417/56649d8c5503460f94a73704/html5/thumbnails/4.jpg)
The Water Supply (Water Fittings) Regulations 1999
• The Regulator is The Secretary of State.
• Domestic Use means water used for Cooking (not food
production), Drinking and Washing.
• Domestic Premises is a single-family dwelling, everywhere else
is a Non-Domestic Premises.
• Therefore an Allotment site with more than one user is a
Non-Domestic Premises.
• Backflow is the returning of substances upstream i.e. toxic
substances getting into the drinking water supply.
Useful Definitions
![Page 5: Water Regulations for Allotment Users 1999 onwards](https://reader035.vdocuments.mx/reader035/viewer/2022081417/56649d8c5503460f94a73704/html5/thumbnails/5.jpg)
The Water Supply (Water Fittings) Regulations 1999
• Came into force 1st July 1999 and replaced the Water Byelaws.
• Byelaws still apply to fittings legally installed before this date.
• A Water Undertaker shall enforce the Requirements of the
Regulations in relation to the area for which it holds an
appointment under Part II of the Act. (Regulation 10 (1)).
• This means that I must enforce Water Regulations at an
Allotment site.
What Water Undertakers are Required to Enforce
![Page 6: Water Regulations for Allotment Users 1999 onwards](https://reader035.vdocuments.mx/reader035/viewer/2022081417/56649d8c5503460f94a73704/html5/thumbnails/6.jpg)
The Water Supply (Water Fittings) Regulations 1999
• The Regulations apply to any Water Fitting Installed or Used, or
to be Installed or Used, in Premises to which Water is or is to be
Supplied by a Water Undertaker. (Regulation 2 (1)).
• Example: - rain water harvesting systems.
• Although not normally full with water supplied by a Water
Undertaker, it is intended to be if necessary, and therefore all
fittings downstream must still comply.
• We encourage the re-use of water.

The Water Supply (Water Fittings) Regulations 1999
Typical examples –
• Outlets left running---hence the preferred use of non-concussive
taps (often called percussion taps).
• Excessive or uncontrolled watering or irrigation
Waste
![Page 15: Water Regulations for Allotment Users 1999 onwards](https://reader035.vdocuments.mx/reader035/viewer/2022081417/56649d8c5503460f94a73704/html5/thumbnails/15.jpg)
The Water Supply (Water Fittings) Regulations 1999
The use of water for purposes other than that for which it is provided.
Typical examples :-
We do not prohibit Allotment watering but must control it.
Remember, we supply Drinking Water for Domestic Use and
Allotment sites with more than one user is Non-Domestic use.
Misuse
![Page 16: Water Regulations for Allotment Users 1999 onwards](https://reader035.vdocuments.mx/reader035/viewer/2022081417/56649d8c5503460f94a73704/html5/thumbnails/16.jpg)

The Water Supply (Water Fittings) Regulations 1999
• This is the taking of water supplied by a water undertaker for which
the appropriate amount has not been paid.
• For example, watering an Allotment used by more than one user
when taking the supply from an unmetered dwelling i.e. running a
hose pipe from someones house.
• Remember, taking water and not paying the correct amount is theft
and could lead to a prosecution.
Erroneous Measurement
![Page 18: Water Regulations for Allotment Users 1999 onwards](https://reader035.vdocuments.mx/reader035/viewer/2022081417/56649d8c5503460f94a73704/html5/thumbnails/18.jpg)

process.

Risk Assessment
• Remember: -
• A risk assessment cannot contradict a
regulation.
• It can apply logic and reason.
• Can clarify installation requirements.
• A risk assessment by a Water
Undertaker can only be superseded by
a better risk assessment.

Q :
What is the worst recorded case of fatalities caused by backflow of a
very toxic substance.
A :
In America from the backflow of weed killer when being diluted
Examples of Backflow Requirements
![Page 35: Water Regulations for Allotment Users 1999 onwards](https://reader035.vdocuments.mx/reader035/viewer/2022081417/56649d8c5503460f94a73704/html5/thumbnails/35.jpg)
The Water Supply (Water Fittings) Regulations 1999
Q :
Can you just promise not to use fertilizers, pesticides and manure
A :
These products are fundamental to Allotment users and although current
users may comply, unknown future users may not; remember the device
used must be un-defeatable and promises can be broken.
Examples of Backflow Requirements
![Page 36: Water Regulations for Allotment Users 1999 onwards](https://reader035.vdocuments.mx/reader035/viewer/2022081417/56649d8c5503460f94a73704/html5/thumbnails/36.jpg)
