Q & A

What is the current global status regarding access to clean water, sanitation, and hygiene in developing nations?

Despite progress, the global community is still off track in meeting Sustainable Development Goal 6 by 2030, with over 1.5 billion people in developing Asian countries lacking access to modern sanitation and around 80% of wastewater being discharged untreated.

How has the global pandemic impacted the need for investments in water and sanitation?

The pandemic has highlighted the urgency for investments in water, sanitation, and hygiene services, emphasizing that these investments must be a key priority in the coming years.

What is the estimated capital investment required to achieve sustainable water and sanitation targets according to the World Bank?

The World Bank estimates that $130 billion USD in capital investment will be needed to achieve the sustainable water and sanitation targets.

What is the concept of 'city-wide inclusive sanitation' and why is it important?

City-wide inclusive sanitation is a comprehensive and holistic approach to urban water and sanitation that considers both basic human needs and environmental protection, cultural and social-political differences, and provides the full sanitation service chain. It is important for achieving sustainable water, sanitation, and sewage systems for all.

What are some of the challenges faced in implementing city-wide sanitation projects?

Challenges include building urban infrastructure, finding financial resources, and addressing the political and social aspects of infrastructure projects. Additionally, there is a need for a more enabling environment, good practices in utilizing international aid, policy reforms, financing schemes, cost recovery, capacity building, and maintaining operations.

How has the Gaubadian wastewater treatment plant in China contributed to the advancement of city-wide sanitation?

The Gaubadian wastewater treatment plant, one of the largest in China, has increased the wastewater treatment rate to over 95% and has provided important lessons that can help accelerate city-wide inclusive sanitation in Asia.

What role do long-term foreign loans play in supporting city-wide inclusive sanitation projects?

Long-term foreign loans provide financial support for projects, enable institutional reforms in corporate governance structures, and fund the acquisition of advanced equipment and technologies, along with training of technical experts.

Why is capacity building crucial for the success of city-wide inclusive sanitation projects?

Capacity building is crucial as it involves the transfer of knowledge, improvement of skills, and project management, which are essential for the successful implementation and sustainability of sanitation projects.

How does setting appropriate tariff rates contribute to the sustainability of sanitation services?

Appropriate tariff rates, based on the principles of cost recovery and reasonable profits, ensure the sustainability of sanitation services. Gradual increases in rates, as seen in the Gaubadian case, contribute to the recovery of operation and maintenance costs and investment in the sanitation sector.

What is the significance of the central government's role in the success of long-term urban sanitation projects?

The central government plays a key role by providing foresight, vision, and political will to embody national policies that support local governments in implementing and achieving long-term sanitation goals.

How does the unique approach of implementing drainage pipes before the treatment plant construction impact the effectiveness of city-wide sanitation?

Implementing drainage pipes before the treatment plant construction, as seen in the Gaubadian case, facilitates door-to-door sewage connections and contributes to the quick and efficient operation of the sanitation system.
