Drinking water – crucial for survival
Above all, drinking water conservation means recognising, reducing and avoiding risks
"Everybody who knows how important, vulnerable and scarce our drinking water has become and doesn’t act accordingly, makes himself accountable."
Manfred Lodewick
Water is one of our core businesses; from the source to the tap or wherever else it is needed.

Drinking Water Ordinance
A clear focus on water quality
Manfred Lodewick launched the drinking water ordinance. All over Germany he discussed and commented on the sector of drinking water with a group of experts.
Water is crucial for the survival of the human race
Even here in our country, where water is abundant and no important hygiene problems exist, clean drinking water is a topic that is constantly discussed.
Even recently contaminated drinking water has led to the death of people in Germany. Most vulnerable are post surgery patients, people suffering from immune deficiency, athletes, and children, the chronically ill and the elderly. If all drinking water regulations were followed during planning, construction and implementation of drinking water systems, the potential risk would be very limited.
The Drinking Water Ordinance 2001 was created to protect the population from potential health hazards.

The situation
The worldwide supply of safe drinking water has become one of the biggest challenges of the 21st century.
Three quarters of the earth are covered in water, but only 0.1% of this is readily available freshwater. Currently 1.1 Billion people have no access to clean drinking water. According to WHO estimates, this number will increase to 4 Billion in 2025.
Every year, more than 2 Million people die due to the lack of water or the consequences of contaminated water. Contaminated water is also responsible for 60% of all diseases that kill children each year. That’s 500 children per day and 1.85 Million in one year. Due to leaking pipe systems about 50% of laboriously won drinking water is lost at distribution. The USA alone will need to invest approx 1 Trillion Dollar by 2025 to fix their ailing water infrastructure.

The solution
More and more countries that have neither sizeable lakes or rivers nor ground and surface water, make use of sea water desalinisation in order to obtain drinking water. However this procedure has many drawbacks. First, it is very expensive due to the high energy consumption and often requires state subsidies. Secondly, it puts a strain on the environment since the saline waste is put back into the sea.
One economical solution is the repair of leaking water supply mains - this can lead to conceivably realistic savings. Drinking water usage will become more economical if leaking water supply mains are repaired. Nowadays it is also possible to employ technologies like special sanitation appliances in industry and farming that reduce the wasting of resources. Wastewater can be treated and reused - so called grey water - which is used to flush toilets and urinals or to water green spaces and farmland.
The most important measure to be taken to save drinking water is changing our attitude and behaviour. The richer a country, the more water is used per person. Especially the world’s wealthiest nations, due to their abundance in oil and other natural resources, use 5 to 10 times more water per head than industrial nations in Western Europe, for example. To counteract this trend, many governments organise large campaigns to make the population aware of the importance of preserving our precious drinking water.

Water projects
In March 2010, Lodewick GmbH received an invitation to introduce their products and services from the Sanctuaries Division of the Ministry of Saudi Arabia.
Lodewick was requested to present a proposal for the water supply and waste water disposal of a stadium to be built for pilgrims coming to do their ablutions. This new project will provide equipment for 16,000 toilets and 20,000 washrooms. During peak visiting periods, e.g. Ramadan, some 45,000 m³ of waste water will be produced.
The RFP contained following requirements:
a) water saving / water usage is of highest priority
b) “touch-less” toilets and washroom (sensor based technology) hard-wear systems (very high amount of users).
c) wastewater treatment for re-usage in toilets and for use as cooling water
d) Assessing and comparing different wastewater disposal systems like gravity sewers, vacuum systems etc.
e) General assessment and recommendation for the stadium
The proposal was finalised in April 2010 and has been sent to the ministry.

A few examples that show how water is (mis)used
- - You need 4100 Litres of waters to produce a cotton T-shirt.
- - 450,000 Litres of water go into the production of a new car. This is due to the high amount of raw material required
- - 2,400 litres of water are used to make one single beef Hamburger
- - 8,000 litres of water are hidden in the productions of a pair of shoes.
- - The same is true for a pair of jeans.
Women in developing countries walk in an average 10-15 kilometres to fetch water. They carry some 20 litres per trip and per person. In some parts of Africa, women and children spend 8 hours a day collecting water.
