We study the environments where preferably reside galaxy systems compounded exclusively by dwarfgalaxies. We identify these systems in a semi{analytical model of galaxy formation coupled to a numerical simulation. Then we divide them in four di erent classi cations according to their environment: knots,  filaments, walls and voids. We  find that more than half of the associations reside in  filaments environments (  63%), followed by walls (  32%), knots (  4%) and voids (  1%). Systems located in more dense environments present velocity dispersion significantly greater than systems located in less dense environments.
