Water is the most precious resource. Without it, there would not be any life on earth. On the other hand, droughts, heavy rainfalls, floods and increasing urbanization put heavy demands on us.
Thus, the objective for us should be to collect the precious water and to return it to its natural hydrological cycle. However, surface water is often contaminated by oil, fuel combustion, tyre abrasion or chlorine from de-icing salt used in winter … certainly everybody knows the puddles on the road shining in an oily rainbow-type manner.
Polluted water is not readily useable for people and, in the worst case, destroys the environment when it gets into the groundwater. In addition, chlorines that are washed into built structures by rain can cause considerable damage such as cracks in the fundament. Sustainable construction is thereby impeded.
Contamination of water will by no means decrease in the future – hence, it is even more important to collect the surface water in a controlled manner and to transport it to places where it can be pre-cleaned. Along this path, no drop should be lost.
For this purpose, we have our drainage channels, however…
COMMON DRAINAGE CHANNELS AREN’T WATERTIGHT
Indeed, common drainage channels only transport a part of the water. A considerable portion of the water is lost into the subsoil due to leaking channel joints.
Despite the fact that the European Union has issued a set of directives on the use of rainwater and on the protection of the groundwater, watertight drainage channel systems are not yet required by law.
FIRST PERMANENTLY WATERTIGHT CHANNEL LAUNCHED
This is where the drainage specialist ACO comes into play, aiming to tackle this problem. For them, it seemed obvious that a controlled rainwater management calls for watertight channel systems. In July 2016, the first drainage channel with integrated seal as standard was introduced to the market – ACO Drain Multiline with Seal in Technology.
How it works? Simply put, the Seal In Technology ensures a continuous tight channel run without losing any drop along the journey in the water hydrological cycle. As a consequence, contaminated rainwater is conveyed in a safe and controlled manner to the water treatment.
What seems to be a logical step represents a true innovation: Watertight drainage channels have been missing so far. The newly developed channel protects the environment, the groundwater and the built structures.
Additionally Co2 equivalents can be reduced with the new ACO Multiline Seal In, leading to an improved ecological assessment. As such, ACO once again makes a contribution to the environment.
USING RAINWATER SUSTAINABLY
Re-using rainwater will become more and more important in the future. Fully absorbed and clean water is a necessary pre-condition for irrigation systems in towns and private gardens, rainwater utilization systems for households and companies as well as for positively influencing the microclimate due to evaporation systems.
