For high-volume hydrators
You drink 4 litres a day. What's actually in it?
Hydration is the right instinct. But here's the catch nobody mentions: the more water you drink, the more of what's in it you consume. On 4 litres a day you're taking in roughly double the microplastics and forever chemicals of an average person. Hydration is only healthy if the water is clean.
The inputs you already track
Everything's dialled in. One input scales with volume.
You measure your macros, your sleep, your sessions. Look at how much you already control.
Your daily inputs
- Train 5 to 6 times a week
- Hit your protein target
- Electrolytes dialled in
- 3 to 4 litres of water a day
- Sleep 8 hours
- 10k steps
- Creatine daily
- Recovery on point
Here's the catch the other inputs don't have: the more of it you drink, the more of whatever's in it you get.
The multiplier nobody mentions
The more you drink, the more you consume.
Contaminant dose is just concentration times volume. So the person hitting their hydration harder than anyone is also, quietly, taking in more of whatever the tap is carrying. It's simple maths working against you.
Roughly double the average adult's intake.
Through your body, whatever's dissolved in it.
Twice the exposure of someone on 2 litres.
- Forever chemicals aren't removed by standard water treatment, and they build up in the body over time.
- Microplastics pass straight through, and have now been detected in human blood.
- Every extra litre adds to the tally. Great habit, wrong water, and the habit works against you.
The volume breaks the usual fixes
At 4 litres a day, bottled and jugs fall apart.
- Bottled water is one of the biggest microplastic sources there is, and at your volume it's a fortune in cash and a mountain of plastic.
- Supermarket jug filters hold a litre or two, so you're refilling all day to keep up, and you're drinking from plastic that can shed microplastics back in. Independent testing has shown that many of these filters can actually increase heavy metal contamination such as aluminium by significant margins.
- Straight from the tap is free and convenient, but it's the exact water carrying the chemicals and metals you're now drinking litres of.
A high-volume habit needs a proper reservoir of clean water, not a jug you're refilling all day.
Seven litres sitting filtered on the worktop covers a full 4-litre day with a bottle spare.

The Waters Co difference
Clean water, by the litre, then re-mineralised.
The BIO 500 MAX holds 7 litres and runs your tap water through 13 stages, removing up to 99.9% of fluoride and up to 99% of chlorine, chemicals, heavy metals and bacteria, filtering microplastics down to 0.1 microns, then adding 60+ trace minerals back at a mild alkaline pH. Fill your bottle straight from the reservoir before every session. For training away from home, Waters Co also makes the portable Waterman filter bottle.
- Targets forever chemicals, pesticides and herbicides, plus lead, fluoride, chlorine and bacteria.
- 7 litre capacity, a full 4-litre day with a bottle spare, no jug to refill every hour.
- Re-mineralised, not stripped, 60+ trace minerals at pH 7.6 to 8.5, so you're not drinking flat, empty water.
- Hand-blown glass reservoir, BPA, BPB and BPS-free build, no plastic sitting in the water you drink most.
13 stages of sterilising, filtration and mineral activation, held in hand-blown glass.
What comes out
What you're no longer drinking by the litre.
Forever chemicals
Not removed by standard treatment. Build up over time.
Microplastics
Pass straight through the tap. Now found in blood.
Lead & heavy metals
Can leach from older pipes and fittings.
Fluoride & chlorine
Added at the treatment works, filtered back out.
Trace minerals added
Re-mineralised at pH 7.6 to 8.5, not stripped like RO.
Glass reservoir
Hand blown, BPA / BPB / BPS-free. No plastic on the water.
Fits straight into your routine
On the worktop in minutes. Fill up before you train.
Set it on the worktop
Compact and lightweight, assembled by hand in a couple of minutes. Gravity-fed, with no drilling, no plumbing, no power.
Keep the reservoir topped up
7 litres of filtered, re-mineralised water ready to go, enough for a full high-volume day without refilling a jug every hour.
Fill your bottle and go
Top up before every session. One filter set runs up to 12,000 litres or 18 months, whichever comes first, at around 3p a litre.

From people who train hard
The habit was right. The water finally caught up.
"I drink close to 5 litres on training days. Realising that meant double the exposure to whatever's in the tap flipped a switch for me. Fill my bottle from it every morning now, and the water actually tastes better."
"I was buying cases of bottled water for the gym and it was costing a fortune, plus all that plastic. This paid for itself fast and the 7 litres easily keeps up with how much I drink in a day."
"Coach always says hydration first. Nobody talks about what's in the water though. Removes the bad stuff and keeps the minerals, so it's not flat like the RO water at my old gym. Easy call."
Straight answers
The questions high-volume drinkers ask us.
Can a bench top filter really keep up with 4 litres a day?
Yes. The BIO 500 MAX holds 7 litres in its reservoir, so there's a full day's worth of filtered water ready to pour rather than a small jug you're constantly refilling. Top it up in the morning and again in the evening and you've always got enough for a heavy training day, plus bottles to take with you.
Isn't bottled water fine for the gym?
Bottled water is one of the largest measured sources of microplastics, and at your volume it's expensive and a lot of plastic waste. Filtering your own and filling a reusable bottle gives you cleaner water at roughly 3p a litre.
Does it strip the minerals out like reverse osmosis?
No. RO strips everything and leaves flat, demineralised water. The BIO 500 MAX removes the contaminants, then re-mineralises with over 60 bio organic trace minerals at a mild alkaline pH of 7.6 to 8.5, so you're drinking mineral-rich water, not empty water.
What about hydrating on the go?
Fill your bottle straight from the reservoir before you head out. For training away from home, Waters Co also makes a portable Waterman filter bottle, so you can filter on the move as well.
How often will I be changing filters at this volume?
The filter set is rated to 12,000 litres or around 18 months of typical household use, whichever comes first. A single heavy drinker will take a long time to reach 12,000 litres, so in practice the 18 month mark is usually what prompts the change. A filter reminder service is available so you don't have to track it.
How much upkeep is it?
Very little. It runs on gravity with no power, no plumbing and no tap connection. You keep it topped up, and swap the filter set when it's due.
