I have already demolished illegal building, why is pipeline connection not yet carried out?

Sewerage Construction is carried out by connecting users of the same lane at a same time; if some of users in the same lane have not yet coordinated to clear out the 1.5m clearance (75cm each side), or when obstacle of underground utility occurs, the entire construction schedule may be affected. Delay may also occur due to pipeline updating of natural gas or water works. For further questions, please dial 25973183-204 or call Citizen’s Hotline 1999, or 02-27208889 if calling from outside of Taipei City.
