Slide 3 – Our Regulators
     Water is a heavily-regulated industry – although we are a private company, we
       provide a very public service.
     Three official regulators – an economic one, an environmental one and a water
       quality one
     The Office of Water Services or Ofwat - is the economic regulator. Every five
       years Ofwat decides what our future investment programme should be and tells
       us by how much we should raise or lower prices to fund it.
     The Environment Agency - or EA – is the environmental regulator. We work with
       the EA to ensure that we take water from and return it to the environment in a
       sustainable way.
     The Drinking Water Inspectorate (DWI) monitors the quality of the UK’s tap
       water.
     We also work very closely with the Health and Safety Executive (HSE) which is
       responsible for protecting the safety and wellbeing of our employees and
       contractors.


Slide 4 – Leakage Detection
     Leakage detection is mostly undertaken late at night when the flows are low and
       the towns and cities are quieter. Electronic sounding equipment is used to detect
       leaks by measuring the level of noise being made by the leak
     We are making significant progress in the amount of water lost from our mains.
       During the last 10 years we have reduced our leakage by 45%, and we have
       consistently out-performed the Government’s mandatory leakage reduction
       targets.


Slide 5 – Water Quality
     Throughout the Treatment process we continuously monitor quality and the
       amounts of chemicals added by sophisticated on line monitors which collect data
       and control the process 24 hours a day, 365 days a year .
     We take water quality samples 365 days of the year; these are from our raw
       water reservoirs, our water treatment works, our service reservoirs and from
       random customer address.
     This means about 600,000 samples each year and about 6 Million different tests.
     This is to check that quality is the best it possible ever at every stage of treatment
       and in distribution.

Slide 6 – Large Interceptor Sewers
Located at Meadowhall, Sheffield (near shopping centre). These sewers were
constructed to take the sewage from large areas of Sheffield to Blackburn Meadows
Sewage Treatment Works


Slide 7 – Scale of our Operations
     Engineers can be seen walking down a new large diameter sewer in order to
       check the condition and workmanship before putting it into service.
     We handle more than 1.7 million tonnes of waste water and trade effluent every
       year- it’s a dirty job but someone’s got to do it!
     Our role is to transport it through 32,000 km’s of sewers to one of our 624
       sewage treatment works where it is cleaned before being pumped back into the
       region’s rivers.
     Since privatisation in 1989 we have spent more than a billion pounds upgrading
       our waste water treatment works.


Slide 8 – Burst Pipe at Rooley Lane, Bradford
     Water is very heavy and we have to move it under great pressure – that’s why
       some small bursts can appear quite spectacular
     That includes Yorkshire Water – we are working hard to reduce the amount of
       water lost through leaks on our system
     We have cut leakage by more than 45% over the past decade and it continues to
       be a priority for us.
     We have successfully met or beaten the targets set for us by the Government
       every year for the past ten years.
     Although we still lose a fifth of our water through leaks, the fact is it is more
       economical to invest in new water resources and reducing consumption, than it is
       to reduce leakage to zero – leakage is an expensive problem to tackle.


Slide 9 – Water Mains Rehabilitation
     Mains rehabilitation is the cleaning, relining or replacing of our water mains to
       improve the quality of the region’s drinking water.
     We are in the process of completing a massive programme of improvements
       across the region.
     When we inherited the system at privatisation in 1989, a lot of the pipes were old
       cast iron mains that had deteriorated over time.
     This meant that discoloration was common place and that there were lots of
       bursts and leaks.
     Since 1989 we have upgraded thousands of kilometres of mains.
     To carry out this work we often had to shut customers’ water supplies off for up to
       36 hours at a time.
     Thanks to new technology, we have now managed to reduce this considerably.
     By 2010, we would like to be in a position where we never have to shut
       customers’ supplies off to carry out repairs – we’ll aim to repair them without any
       interruptions.

Slide 10 – Water Safety
Whilst life is impossible without water, water can also be very dangerous.


Slide 11 – Water Safety
     Whilst we are always pleased to have people visiting our reservoirs, we do stress
       that you must obey the signs and be aware of the dangers.
     On hot days, a dip in a reservoir may appear like a great way to cool down.
       Although the still water may seem harmless, it’s actually an insidious killer which
       can claim a life in minutes!

       What are the dangers?

   •   Strong Currents - these lurk beneath the surface, particularly if water is being
       drawn through massive pipes beneath the surface.
   •   The Cold & Hyperventilation - often, when fatalities have occurred in the past, it’s
       been the temperature of the water which has been the most significant factor.
   •   Reservoirs are deep and the water in them doesn’t ebb or flow like in rivers or the
       sea so the temperature rarely rises much above 12C.
   •   Immersion is enough to take most people’s breath away but what they probably
       don’t realise is that this sensation is their body’s natural defences kicking in – and
       they will only protect a swimmer for a matter of minutes, no matter how confident
       they are in the water.
   •   One of the first signs of trouble is hyperventilation as the body tries to increase
       the flow of oxygen into the blood to help stave off the cold but, if the swimmer
       remains in the water, the body will begin to shut down to protect the vital organs.
       Muscles will go into cramp and suddenly it’s no longer possible to swim. The
       victim will try to fight to stay on the surface but, if help doesn’t arrive within
       seconds, they will be drawn inexorably underwater, even though they may still be
       fully conscious and aware of what’s happening.


Slide 12 – Guess the sign game.
Ask the children to guess what the signs mean. Press return for each sign and then its
meaning to come up. There are 10 in total
