Read Our COVID-19 Update – May 2020

As of the 1st May 2021, our team are Lateral Flow testing for the symptoms of COVID twice a week, in order to keep our staff, customers and families safe.

Our team continues to follow all strict social distancing guidelines, including sanitising and now the wearing of masks in customer homes where customers are present and this is appropriate.

If we are working within your home, such as changing a filter or servicing a softener, or installing a new softener, we would ask that the area we are working be well ventilated.

The company policy is that we will sanitise our hands on arrival at your home, and on departure too. If we touch surfaces within your home, we will inform you which surfaces we have touched, and we will sanitise those surfaces too with a light bleach solution before we leave.

Our salt was manufactured and stored on pallets more than 30 days ago, and will only have been touched by the member of our team who delivers it, and their hands will be sanitised. We will deliver your salt to your home, and if safe to do so, will leave it in your desired location. If you would prefer your salt to be left outside your home, then we will ascertain beforehand where your preferred safe point is.

Lastly, we will confirm with you that no one in your home is experiencing symptoms or self isolating when booking the appointment to come and see you, plus when confirming the appointment the day before, Daniel will also confirm that no one in your home is self isolating or experiencing symptoms at that time too.

As a final precaution, when we are on our way to your home, the individual coming (Laurence, Alex, Paul or Pete) will also call you to confirm that not only are we experiencing no symptoms, but to ascertain that no circumstances in your own home has changed either.

We remain committed to the safety of our clients, and together we will get through this safely.

Any questions, please call Laurence on 07976 036101 or email the team on hello@hydroworks.co.uk

Where does our local hard water come from?

The majority (70%) of our supply in Kent comes from groundwater, predominantly from the chalk aquifer which is widespread across the region, the cause of all the hard water we get in our homes. A further 23% comes from rivers and the remaining seven 7% from surface water reservoirs owned by Southern Water.

Hard water comes from chalk which was created millions of years ago by rising sea levels. Chalk comes from the remains of tiny organisms that today provides fossil collecting opportunities. At the end of Chalk times (65 million years ago), sea levels fell and South-East England was uplifted. This led to the widespread erosion of the chalk, clearly evident in the corner of the Isle of Thanet near Pegwell Bay.

Some parts of Kent and East Sussex have incredibly hard water with all the effects of hard water visible around our homes. Other parts of the region have softer water. The map to the right highlights where the hardest water can be found, and although in softer water areas scale is less likely, all the cosmetic staining from dissolved chalk still leaves damaging marks around our homes.

If you imagine the bed of chalk that our water goes through as ground coffee beans within a coffee percolator. The thicker that bed of coffee, the stronger and richer the cup. The same applies to chalk.

Because chalk dissolves when water passes through it, literally into a colourless, see-through glass of water, it is only when it dries or is boiled that residue forms again, leaving unsightly staining and scaling. The thicker the bed of chalk that the water passes through, the harder the water. This is why even in soft water areas we get the cosmetic staining of hard water as there is still some degree of chalk in the water supply.

So how safe is our water to drink?

Firstly, let's be clear, it is safe to drink your water. Your choice to filter it comes down to your personal choice and perception of taste

The calcium in hard water is good for us, right? Our bodies need calcium to make our bones strong, and it is true that chalk gives us this important source of calcium. However, there is more to it than meets the eye…

Dairy calcium is fully absorbed by our bodies

There are two forms of calcium – Dairy calcium and Rock calcium. Our bodies can fully absorb the calcium found in dairy products, however, we have less success absorbing rock calcium.

As a result, any excess rock calcium we absorb that doesn't get flushed down the toilet when we go to the loo can be left behind in our kidneys, and there are some suggestions that this can contribute to painful kidney stones. For more information on this subject: What is the position on kidney stones and hard or softened water?

Rock Calcium. Is that chalk?

Yes, quite like the chalk we use to write on blackboards.

It's perfectly harmless though. If you run a glass of water straight from your tap, it's almost impossible to see as it has dissolved in the water supply.

There is chalk in our water supply?

You might think we are kidding, and you'd be forgiven for thinking that! But the short answer is yes. And you'd be astonished to see how much there actually is. In fact, if you'd like to see for yourself exactly how much chalk is in your water, we'll be happy to come and do a simple test to show you.

Here is a sample of water I took on March 13th, 2018 in Headcorn, near Ashford. The central glass vial is sat inside a glass of normal tap water, to show the difference between what we can see, and what we can't.

"So, if it is as safe as they say, we can just drink tap water, right?"

YES!

OK, so if we can drink it, why do so many people filter it?

The answer to this comes simply down to our own individual preferences to taste.

If all you have ever drunk is incoming hard water straight off the mains, then the pure water is masked by chlorine and dissolved chalk. But it is in fairness perfectly safe to drink. A lot of people, however, don't like the flavour of mains water, and some people just don't trust it either.

But where does this distrust stem from?

It doesn't help when from time to time we are instructed by the water boards to boil our water due to unsafe levels of bacteria detected. That gives a lot of people cause for concern. However, the real trust is closer to home, and the answer can be seen in our kettles and glasses of water.

The chalk in hard water sticks together, causing scale. This chalk leaves a film on our cups of tea and damages our appliances.
With hard water, we have to use so much more cordial in the water, simply to mask the taste of the chalk and chlorine in the water.
Very frequently, as we draw water from the incoming mains, we can see and smell the pungent smell of chlorine. This is a most unpleasant smell!

Water Treatment

How We Use Our Water

In Kent and Sussex, regional statistics state that every person uses approximately 156 litres of water a day, and this figure has been growing by approximately 1% a year with the advance of larger showerheads and pumped water systems used in modern British homes.

Of all this water, only 4% is used for drinking water and food preparation purposes – that's just 6 litres a day!

With so little water used for drinking and food preparation purposes, mains water is treated at water treatment plants to be safe enough to drink, but that is it – no further treatment happens to it once it leaves the water treatment works, and so by the time it reaches you, it will be very different as it will pick up contaminants, sediment, and minerals along the way.

So with 160 litres of water per person being consumed every day, where does it all go if just 4% is used for drinking water?

  • We each use on average 156 litres of water a day.
  • 29 litres is flushed down the toilet.
  • 9 litres is used to wash dishes and around the kitchen.
  • 43 litres is used for personal hygiene.
  • 23 litres is used to wash our clothes.
  • 18 litres is used outside.
  • 28 litres is used for miscellaneous internal use including washes the pets, cleaning, and leaks.
  • Just 6 litres is used for drinking tea, coffee, glasses of water or squash.

The Water Treatment Process

So how is our water treated?

At this point, your water passes its quality tests…

It still has to be sent to pumping stations, pumped through hundreds of pipes, into your street and then on into your home, from there making its way through your pipework before making its way eventually to your kitchen tap.

That's a long distance to cover without any further treatment.

Step 1 – Water is collected in reservoirs and from aquifers …

Steps 1–3

Step 2 – and pumped to water treatment works…

Step 3 – where the water treatment and the cleansing process begins.

Step 4 – As the water is filtered, solids are removed…

Step 4

Step 5 – and eventually chlorine is added to purify the water and kill off any bugs …

Steps 5–8

Step 6 – after which the water quality is tested and passed as "fit for consumption".

Step 7 – From there it goes to storage reservoirs…

Step 8 – and a final water pumping station…

Step 9 – before being pumped to your neighbourhood, and home ready for your use. Along the way can pick up sediment, and taste & odours you may prefer to filter out.

Steps 9–12

Step 10 – Once in your home, it goes to your own cold water tank or hot water cylinder…

Step 11 – where your water is stored, ready for your use.

Step 12 – Eventually we open our taps, and bathe or drink our water. The chlorine that was added around step 9 continues to be present in our water supply.

The important factors that determine our enjoyment of drinking water, i.e. the taste of it, are left to the individual homeowner to manage.

So it makes sense that the water we drink should be better quality than the water we flush down the drain or use to water the garden.
