Description
The project is investing in rehabilitation and expansion of sewerage network, modernization and expansion of wastewater treatment plants (WWTPs), and improvement of wastewater management in the Kathmandu Valley that will help improve service delivery and reduce pollution of the Bagmati River and its tributaries. The project is also strengthening the institutions working for wastewater management in the Kathmandu Valley to increase operational efficiency and improve service delivery, and will result in positive impacts on health and quality of life for the residents of Kathmandu Valley. The project is coordinating with other related projects to fulfill the medium-term priority investment needs identified in the long-term capital investment and asset management program.
Project Rationale and Linkage to Country/Regional Strategy
Rapid and unplanned urban growth and inadequate investments in wastewater management have resulted in poor quality wastewater services in the Kathmandu Valley. The disposal of untreated sewage in rivers affects the quality of surface and ground water and increases disease incidence, health risks, and associated economic burdens. With the completion of the ongoing Melamchi Water Supply Project-Phase 1, the Kathmandu Valley is likely to receive substantial additional water by 2019. The sewerage system, which is inadequate even to manage existing low levels of water supply, will be further overburdened by additional wastewater. The project will complement past and ongoing efforts of the government toward improving wastewater services in the Kathmandu Valley. The project is consistent with ADB's Nepal country partnership strategy at the time of processing, which aims to support Nepal's peace and development aspirations by promoting the following four pillars: (i) broad-based and inclusive economic growth, (ii) inclusive social development, (iii) governance and capacity building, and (iv) climate change adaptation and environmental sustainability. The project fits into the priority water supply and other municipal infrastructure and services sector, identified in the country partnership strategy, and will support the country's peace and development through improved access to basic services. The project is included in the Nepal country operations business plan at the time of processing.
Impact
Sustainable wastewater management for Kathmandu Valley.

Status of Implementation Progress (Outputs, Activities, and Issues)
1.Sewerage network rehabilitated and expanded.
Under the Project, it is possible to rehabilitate only 2.8 km of combined sewers under the SN-03 package. Other combined sewer packages have been dropped, due to low readiness and complementary efforts by private houseowners and other agencies. So far, 1.1km laid.
A total of 44.36 km ( revised target) of interceptor sewers was expected to be laid by the river banks under three contract packages. The works completed after achieving following:
Progress to date is 29.51km:
KUKL/WW/IS-01: Hanumante 16.32 km
KUKL/WW/IS-02: Manohara 5.5 km
KUKL/WW/IS-03: Kashyang Khusung 7.06 km
KUKL/WW/TP-02: Manohara 0.63 km
A new sewer package for peri-urban areas under SN-04 is introduced and is under procurement.
2. Wastewater treatment plants modernized and expanded.
I. WW/TP/01 Guheshwori (32.4 MLD: construction completed and operation ongoing since September 2020). Has power generation facility from the sludge of 230 kW.
II. WW/TP/02 - Sallaghari, Kodku and Dhobighat (68.7 MLD): detailed design completed (overall progress: 25%). Contract terminated after no improvement to contractor's poor performances. Repackaging undergoin.
III. WW/TP/03 Dhobighat (37 MLD): Construction ongoing. Overall progress about 75%. Commissioning expected in Q1 2023.
IV. DEWATS: Decentralized wastewater treatment facility introduced for two peri-urban areas Gokarna (3MLD) and Hanumanghat (1MLD). Contract Awarded in March 2022. Performance of contractor is unsatisfactory.
3. Capacities strengthened and operational and financial reforms institutionalized.
Sewerage asset database, wastewater master plan, GIS, and asset management plan prepared.
Environmental monitoring of wastewater quality is ongoing at Guheswori Treatment Plant.

Summary of Environmental and Social Aspects
Environmental Aspects
The project is classified as category B for environment. Initial environmental examinations (IEEs) and associated environmental management plans (EMPs) were prepared and disclosed in accordance with ADB's Safeguard Policy Statement, 2009. An Environmental Assessment and Review Framework (EARF) was prepared to guide the environmental assessment of pilot decentralized wastewater treatment systems to be later defined through detailed design. The IEEs and the EMPs for the various construction packages are being updated during detailed design and incorporated into contract documents. The IEEs show substantive net positive environmental benefits, including (i) improved wastewater management to safeguard public health, and (ii) cleaner waterways and urban environment through increased sewage treatment. Pipe laying works within roads passing through heritage areas will take additional measures to ensure no impacts during construction. Permission from the Department of Archaeology will be obtained prior to commencement of construction, particularly in Patan and Durbar Squares. Measures to manage any impacts pertaining to slope stability, erosion and sedimentation will be implemented prior to laying of interceptors along the rivers. As part of the detailed design of the new WWTPs, air quality dispersion modeling will be conducted to ensure adequate odor management measures are incorporated into the project design and environmental monitoring system. In addition, perimeter buffers will be established along the boundary of the WWTPs to minimize odors released from the premises. In order to ensure optimal operations of WWTPs at all times, safety plans will be developed and implemented.
Involuntary Resettlement
Resettlement plan (RP) and a resettlement framework were prepared and disclosed in accordance with Safeguards Policy Statement of ADB (SPS, 2009), and have been updated in 2018. There is no land acquisition envisaged under the project. All land for the construction of WWTPs and sewerage network is located in the existing WWTP sites or within government lands along the roads or river banks. Most of the land acquisition for the WWTPs was carried out during the late 1970s and early 1980s. The project will ensure that these lands acquired for WWTPs continue to comply with all relevant laws and policies of the government. The impacts during construction will be limited to (i) temporary losses for a few cultivators along the river banks during the laying of sewers; (ii) temporary disruption of business activities, and temporary shifting of vendors and hawkers during construction of works; and (iii) permanent loss of access to land for a few informal cultivators. The impacts will be limited and compensation for lost income will be provided to those affected as per the resettlement plan and resettlement framework. For any land acquisition in anticipation of future ADB financing, the government will be required to comply with ADB Safeguards Policy Statements (2009) in addition to relevant government laws.
Indigenous Peoples
No adverse impacts on indigenous peoples are anticipated, and improved wastewater facilities will benefit all households, including the indigenous peoples in the project areas. The project will avoid cultural sites used by indigenous people, if identified during detailed design. Meaningful and widespread consultations will continue with all communities in the project area.
Stakeholder Communication, Participation, and Consultation
During Project Design
During the project design, adequate consultations were carried out with important stakeholders in the form of surveys, workshops, focus group discussions (FGDs) with beneficiaries, NGOs, and other stakeholders; steering committee meetings and PPTA review meetings.
During Project Implementation
During project design, a community awareness and participation plan has been prepared to involve various stakeholders including the poor and socially excluded sections of the population. Adequate resources have been provided to implement and monitor the plan.
Business Opportunities
