   «Чистый сток» — a template for companies that sell and install septic
   tanks, treatment stations and drainage.

   Cool aqua paper, deep teal, a touch of blue and graphite; clean
   engineering line work (tank sections, water levels, a wavy water line),
   a round geometric grotesque and white cards with soft shadows.
