We saw the sewage purification plant system of Smiltene and of Lena. They are diferent. In Smiltene part of the system is outside, but in Lena everything is inside. The systems work different, but result is the same.
We saw how technology were working. And it was amazing – all that process give us practically perfectly cleat water. And when thouse sewage purification plant system had been cleaned the water, they turn it beck in to the river. Now we know that in this way we give nature beck 98% clean water. It was great experience.
