The search for happiness, hydration and health

How much drinking water do we need per day? Good question.

Tardis H2o has the answer.

We all know that good hydration is essential for our health and wellbeing, considering that 70% of the human body is made up of water.

We at Tardis H2o on site are often asked how much drinking water a person needs to maintain a healthy demeanor. The answer is dependent on a number of factors. One of the factors is physical build, a person’s physical activity and the weather can make a difference. A hot humid environment for instance would make you lose valuable fluids through perspiration.

We should take note of what our bodies are trying to tell us and the first signs of dehydration can include a dry mouth, lightheadedness and fatigue. In its extremes chronic dehydration can effect body functions such as the kidneys and lead to muscle damaged.

This is why you will often see during large music festivals, events and even raves, people drinking copious quantities of good old H2o. Water really is the best cure.

In situations such as this the worst thing to do would be drink alcohol which would add to the dehydrative effect.

When you are responsible for a gathering where people may be at risk of dehydration there are a number of options open to provide what people need.

Probably the simplest is bottled drinking water because of its self-contained ease of use. For outdoor events you may consider using a specially prepared drinking water bowser. When we say specially prepared we mean that the vessel and the water it contains meet strict guidelines laid out by the Health and Safety Executive and the Drinking Water Inspectorate. Also fittings such as taps and connectors must be WRAS approved (Water Regulations Advisory Scheme).

Storage of drinking water is also strictly regulated and must not exceed 48 hours in a tamperproof vessel without testing for E-coli as a minimum. Tests should also be carried out every 48 hours afterwards to assure that the water is fit for purpose (drinking).

Taking into consideration these factors, a rough guide as to how much a person should drink to maintain hydration, 2 litres per day (approximately half a gallon) is the amount advised.

However one should take into account the physiology of the individual. There are no hard and fast rules, just general advice.

The body has many mechanisms for alerting an individual to its needs; thirst being one of them in this case. Taking into consideration what has been said thus far, you can begin to calculate the amount of wholesome drinking water you will need to keep people happy, healthy and hydrated with an idea of how you will store it too.

Moving to the extreme, Tardis H2o on site have provided a tanker filled with 16,000 litres of drinking water and a special dispensing station in recent weeks though our maximum current capacity is a whopping 32,000 litres, enough to swim in let alone drink.
