Sewerage System is an essential infrastructure for modern cities. If a city’s water pipeline was the urban artery, the sewerage pipeline would be the urban veins. All human activities generate domestic sewage and industrial wastewater; both of them are collected by sewerage system and delivered to the sewage treatment plant. The plant treats the sewage and wastewater to the national standards of effluent, to avoid water quality of the river, lake and ocean from being polluted. Modern sewage treatment plants are upgraded to resource recycling plants; reusing the treated effluent is a trend of future developments to maintain the precious water resource become sustainable, everlasting and well preserved.
Fifty years have elapsed since Taipei City started the sewerage systems construction in 1972; user connection rate is on top of all cities in Taiwan. The design and operations of sewage treatment plants are so advanced and bountiful experiences have been accumulated in terms of planning, design, engineering method, statutory specifications as well as maintenance and operations. At the same time, interactive exchange has been made with sewerage authorities of the central government as well as local governments. SSO continues to promote sewerage infrastructure based on “Taipei City Sewerage System Subsequent Development Program” promulgated in 2016, with the following tasks as key execution items:
- Total autonomy in city sewerage by 2030.
- Achieve 90% house number user connection rate by 2032.
- Achieve Tamsui River System activation objectives via qualitative and quantitative improvements.
- Continued promotion for sewerage infrastructure.
- Maintain stable operations of sewerage systems.
- Minimize rainwater infiltration.
- Improve emergency response capability of the system, reduce occurrence of disasters, and consolidate system safety.
- Energy saving, resource recycling and improved biological benefits.
- Achieve sustainable operations of sewerage systems by continued upgrading and prolonged service life.
- Promote sewerage education and international exchange; elevate international status and social image.
