• Two TAPS support buildings: one-story steel-reinforced concrete
  structures, each approximately 33 feet wide x 222 feet long
• Steel-reinforced, concrete box effluent conduits: these water transporting conduits vary in size from 7 feet wide x 7 feet long opening to 16 feet wide x 12 feet long
• Steel-reinforced, concrete junction chambers: these collect
  water to be transported via effluent conduits.
• Bulkheads and relief structures: diverting of existing plant flows
