• Any apartment complexes with more than 50 dwelling units should install sewage treatment plant (STP)
  • Deadline: December 31, 2017
  • Penalty: First three months: 25% of water bill monthly; thereafter, 50% of water bill monthly
  • Issues: No space to construct STPs; structural stability of existing buildings could be endangered as underground STPs come close to load-bearing pillars; cost of STP becomes high
