THose are BS

we have few CD bunkers and quite long drain pipes but thats all not more than 5000 thousands people can fit in those shelters, Wroclaw isn't on rock but on sand and has very high level of ground waters, thats why we don't have chances for metro, or other deeply put constructions...its almost impossible to build any tunnels here without destroying things with are above and keeping them dry is another big problem... We also has quite malaric climat as we are in hot centre of Poland and have very wet air...
