Some simple solutions (for each use and local conditions) and NATURAL exist to preserve, use of water resources and the return to nature in minimizing environmental pollution.

systems:
> Rainwater harvesting
> Water Treatment and Wastewater
> Sites remediation
Water resources:
the challenge is to have water in sufficient quantity, the quality
is suitable for each use, taking into account local conditions (climate,
rainfall, surface water, location and type of habitat, customs and
regulations ...)
DRINKING WATER
Over one billion people worldwide lack access to safe drinking water and more than 6 million people (of which 2 million are children) die from diarrhea each year. This situation persists and continues to cause enormous casualties until the problem is not seriously considered at all levels.
In
developing countries stations, water treatment are expensive and poorly
adapted technologies to lack of local expertise.
To circumvent these difficulties it is necessary to promote sustainable
supply systems and water treatment, which have the advantage of being
cheap, robust and require little maintenance and technical skills. We
must also highlight local materials locally available.
Rainwater: a precious commodity too often neglected
Recovery of rainwater for human consumption of drinking water is largely overlooked in our modern societies, although it is good water quality. It is often reserved for irrigation, outdoor uses, toilet flushing and sometimes, though rarely, for washing.
Many countries prohibit the use of rainwater for drinking water production.
But, if properly conducted, the recovery of rainwater, as it requires
little investment, is a compelling solution for drinking water in the
developping countries.
