Ensure availability and sustainable
management of water and sanitation for all

Relevant initiatives include the establishment of a safe water resource management system for the whole process from the stable supply of safe tap water to the proper treatment of sewage as well as the enhancement of existing water supply network facilities and monitoring systems. The goal lies in the reduction of water resource losses during the water supply process, and the promotion of reclaimed water use and rainwater recycling in order to fully utilize water cycling and reuse.

City’s Current UN Sustainable Development Targets

Targets 6.1

By 2030, achieve universal and equitable access to safe and affordable drinking water for all.

Targets 6.3

By 2030, improve water quality by reducing pollution, eliminating dumping and minimizingrelease of hazardous chemicals and materials, halving the proportion of untreated wastewaterand substantially increasing recycling and safe reuse globally.

Providing Stable Tap Water Sources

Taiwan ranks 18th among the world’s most water-stressed countries. Water resources are very precious, and a water reservoir plays a very important role in storing water resources. How to effectively enhance reservoir water utilization rates and promote the sustainable management of reservoirs remain very important issues at hand.

Feitsui Reservoir is an important livelihood and public water source for the Greater Taipei metropolitan area. Currently, the water supply can accommodate up to five million people; in the future, it is expected to accommodate up to six million people. In order to ensure Feitsui Reservoir can meet water supply needs and construct Greater Taipei into an environment without water shortages. In the future, reservoir operations must continue to be improved so as to strengthen water resource utilization. An increase in reservoir water source utilization not only ensures water supply stability, but also reduces the flushing volume during typhoons and floods as well as the occurrences of reservoir downstream flooding. In order to increase reservoir water utilization, the “Feitsui Reservoir Stable Water Supply Plan”, the “Feitsui Reservoir Intelligent Management Plan”, and the “Feitsui Reservoir Operation Plan” have been drafted.

Water Supply Pipe Network Improvement Strategy

In view of the water resources becoming increasingly scarce, in order to effectively use water resources, prevent system leakage, and reduce the water leakage rate, the city has planned 20-year “Water Supply Pipe Network Improvement and Management Plan” long-term strategic approach(Year 2006~2025)to be executed in four stages. At present, Stage 3 is in progress(Year 2016~2020),thereby comprehensively promoting the “regional water quantity measurement” engineering method to control water leakage improvement effectiveness. In addition, according to the water leakage management strategy for pipe network water loss recommended by the International Water Association(IWA), pipeline replacement, water pressure management, voluntary water leakage detection, and leakage rate quality serve as the four main directions for perfecting the water supply pipe network system and gradually reduce water leakage rates by taking a combination of measures.

Proper Sewage Treatment Strategy

The city’s proper sewage treatment strategy involves collecting family wastewater, business wastewater, etc., through the sewer system to the sewage treatment plant, which purifies and properly disposes wastewater until it meets the national effluent standard for discharge.

In 2019, the city actively conducted Phase 5 pipe network engineering and user discharge equipment engineering in respective administrative districts of Taipei City; the Phase 6 engineering project (Year 2020~2023) will continue to be conducted, with appropriate engineering methods adopted to continue promoting user pipe connection engineering and conducting pipe life extension operations, in the hope of comprehensively enhancing household pipe connection rates and prolonging pipe life, as well as increasing the ratio of population entitled to wastewater treatment. The targeted number of household pipe connections is 10,000 in 2019 and 8,000 by 2020 and 2021. Additionally, based on the actual pipe connection statuses of respective years, periodic revision on targeted numbers of household pipe connections for respective years will be done, thus sequentially enhancing the ratio of population entitled to wastewater treatment.

Improving Water Contamination Improvement Rates

The city’s implementation of the water pollution source control permit system targets water pollution prevention measures for adoption by business entities, including: self-setup(wastewater) water treatment facilities, recycling and reuse, storage, inclusion for sewer system treatment, consigned treatment, and other methods. According to regulations, a permit application is required by law in order to fully grasp pollution source data. Water pollution source control requires periodic declaration of wastewater treatment facility operations, effluent water quality and quantity testing and electricity consumption records as provisioned, thereby supervising normal operations and maintaining wastewater treatment facilities, as well as strictly executing terminal inspection and control work.

Creating Excellent Water Quality Actions

In terms of water pollution prevention, construction sites, the city’s controlled businesses mainly focus on community sewer systems, hospital and medical institutions, and tourism-oriented hotels. In order to grasp business and community sewer system pollutant discharge, controlled business and sewer system pollution inspection will continue to be strengthened, with the controlled target inspection rate of 100% as the target. Moreover, effluent quality is timely sampled and tested, and traders are urged to implement the normal power-on, operation, and prop declaration of sewage treatment facilities, so as carry out water pollution prevention work.

The city promotes citizen participation in water environment patrols and river conservation, thus purifying rivers, reducing pollution, and expanding environmental education on water through citizen power. The city’s water environment patrol consists of 19 teamswhose total patrol range stretches 102 km, including the Jingmei River, Xindian River, Keelung River, and Danshui River and who forms a rigorous monitoring network covering rivers in Taipei City. River cleaning and river purifying activities are also regularly held to enable city residents to be closer to rivers and join to safeguard the water environment in concerted efforts.

Furthermore, at Guandu Natural Park, the Shuimokeng River wetland operation and maintenance are done. Water improvement is done through natural purification engineering methods, with the water treatment capacity exceeding 2,500 CMD.

Comprehensively Enhancing Recycled Water Usage

After sewage has been properly treated in the treatment plant, the city adhering by the spirit of the circular economy to enhance the “ratio of three levels of waste water treatment” to increase the comprehensive recycling and use capacity for use by other units free of charge. Recycled water for water plants, environmental cleaning, street cooling, and other non-human contact uses are actively promoted, which combined with environmental education courses promote the advantages of recycled water and the importance of water resource recycling and use.

Sewage treatment upgrade and recycled water quality and quantity enhancement continue to be promoted. The recycling capacities of the city’s Dihua Sewage Treatment Plant and Neihu Sewage Treatment Plant account for 10,000 CMD and 20,000 CMD respectively. After treatment, water is provided for factory wash use, plant watering, road cooling, equipment cleaning, and secondary water use by the general public. From 2015 to 2018, the average monthly recycled water usage reached 216,201 m , equivalent to the saving about 36.04 million bottles of 600c.c. bottled water each month.

Rainwater Recycle and Reuse

In order to promote the recycle and reuse of park rainwater, the Parks and Street Lights Office, Public Works Department, Taipei City Government promoted the setup of rainwater harvesting in 17 parks from 2015 to the end of 2018, with the total capacity of 996.43 m  for irrigation and secondary water resource uses. In addition, rainwater harvesting with the capacity of 467 m were set up in 95 schools, including: Minsheng Elementary School, Dongmen Elementary School, Taipei Municipal Zhishan Elementary School, Guting Junior High School, etc.
