Sri Lanka: Greater Colombo Wastewater Management Project

Sovereign Project | 36173-013

The Project is designed to improve the urban environment and public health for the urban and suburban residents in Colombo through improvements to wastewater management services. The Project will support (i) upgrading the sewerage infrastructure, including pumping stations, sewer pipes, and discharge outfalls; (ii) strengthening institutional and operational capacity in asset management, financial management, operational performance monitoring, environmental regulatory compliance, customer services, and pro-poor sanitation services; and (iii) project management and implementation.

Description

The Project is designed to improve the urban environment and public health for the urban and suburban residents in Colombo through improvements to wastewater management services. The Project will support (i) upgrading the sewerage infrastructure, including pumping stations, sewer pipes, and discharge outfalls; (ii) strengthening institutional and operational capacity in asset management, financial management, operational performance monitoring, environmental regulatory compliance, customer services, and pro-poor sanitation services; and (iii) project management and implementation.

Project Rationale and Linkage to Country/Regional Strategy

Colombo is Sri Lanka's economic and administrative center. The Government, in its Ten-Year Development Framework, 20062016, targets high and steady economic growth and modernization of the capital region as the national growth engine. The Western Region Structure Plan, adopted by the Government as the development plan for the country's capital region, emphasizes the critical role of basic infrastructure and services, including wastewater management, in sustaining the national economy and improving the quality of life in the Greater Colombo area.

While the Colombo urban area is rapidly expanding, the coverage of the existing public sewerage infrastructure is limited. Most of the system has been run exceeding its technical life and is therefore inefficient and unreliable. Emergency repairs rather than planned maintenance are normal practices. Assets are not inventoried and there is no accurate database on the condition of assets. The customer database is inaccurate and is not regularly updated. Frequent blockages in the system cause flooding in lowlying areas and the uncontrolled overflow has serious environment and public health implications. There is no institutionalized mechanism to monitor operational performance or environmental compliance.

Impact

Urban environment and public health are improved for urban residents in Greater Colombo.

Accordingly, by 2023:

(i). Inland and marine water quality within Colombo complies with CEA quality standards.

(ii). Incidence of the water borne diseases is reduced by 20% from 2009 figures.

(iii). Number of underserved low-income settlements reduced by 30% from 1,640 in 2009.

Project Outcome
Description of Outcome

Urban population in Greater Colombo enjoys better wastewater Management services.

Progress Toward Outcome

All planned contracts for works, equipment supply, and consultancy were awarded. The NWSDB component has been physically completed and taken over. The CMC component works are in progress. Out of the total 6 works/supply contract, two were completed, one was physically completed, one was terminated, and the balance two are in progress. As of 15 September 2021, around 89% of the ADB financing was disbursed.

Due to the Covid-19 lockdown from March-2020, field works were significantly slowed down. Works recommenced during Q3-2020 but delays continued with sporadic pandemic lockdowns. The EA/IA has indicated another loan till 31 December 2022.

Implementation Progress
Description of Project Outputs

Sewerage infrastructure is upgraded

Institutional and operational capacity of CMC is strengthened

Project management and implementation capacity of CMC is improved

Status of Implementation Progress (Outputs, Activities, and Issues)

1. Sewerage infrastructure:

+CMC Component - Contract for the rehabilitation of the two sea outfalls are completed and the outfalls are functional. An essential mobile plant for CMC has been procured. Out of the 11 planned pumping stations for rehabilitation, one was completed and taken over, 3 are about to be taken over, works on 4 are ongoing, and 3 were taken out of the scope of works. Around 8 km of major new sewer lines were finalized for construction and works completed. Additional works are ongoing. CCTV conditional assessment of the targeted 125 km sewers is completed. Cleaning of 15km of sewers and reduced blockages cancelled and this was combined with the sewer rehabilitation contract for cleaning and CCTV survey of 125km length of sewers. Additional works, which are required by the CMC, are included under contract variations. Interconnections identified were given to CMC for disconnection by improving stormwater facilities. Through CCTV survey further interconnections are identified for CMC to find solutions. The borrower is proposing another loan extension till 31 December 2022 for the balance works to be completed.

+NWSDB Component - All 6 pumping stations were rehabilitated and taken over by NWSDB and are now operational.

2. Institutional and operational capacity of CMC:

The other consultancy contract for Institutional Development of the CMC's Drainage Dept. was completed. accordingly, an asset management system was developed. Pilot database of pumping stations that were not under rehabilitation contract, developed. CCTV data is being linked to the sewer network asset database. FMAS system installed and the system is running. Network installation completed. Works under project scope completed. Additional activities associated with this output (mainly training and workshops) identified under ADB financed MFF-T3 project, is continued to be financed under this loan. More than 750 person-days of training were provided on various subjects. Mapping completed and modelling partially completed to fit the requirement. Environmental monitoring mechanism- completed. Customer charter was discontinued as agreed with the Review Mission held from 21 - 27 May 2013 (Aide Memoire). Community Participation, Public Education program and School education program all completed.

3. Project management and implementation capacity:

CMC-PMU is operational and the NWSDB-PIU has been closed out. CMC-PMU continue to face limitations in filling its staff cadre. All planned major contracts awarded. Works Ongoing. An original Consultancy contract for Design and Supervision came to completion and the balance works are continued with a team of individual consultants.

Stakeholder Communication, Participation, and Consultation
During Project Design

A diversity analysis has been undertaken before the stakeholder analysis covering physical, socioeconomic, and usage diversity. Stakeholder mapping_identified direct and indirect beneficiaries, pressure groups, and other interest groups at the national, divisional, project, and community levels. The stakeholders were grouped into seven categories comprising: (i) users of the main sewerage system, (ii) users of septic tanks in areas not served by the sewerage system, (iii) managers of sewerage systems, (iv) other service providers, (v) regulators and administrators, (vi) policy makers, and (vii) other interest groups. The expectations and likely benefits, and issues and concerns, of these stakeholders were analyzed in the stakeholder analysis and considered in the project design, particularly in developing participation strategies. Information dissemination and consultations have been undertaken to ensure stakeholder participation in project design.

During Project Implementation Information dissemination and consultation will continue throughout project implementation through public awareness programs and national steering committee meetings.
Business Opportunities
Consulting Services Two consulting firms recruited for (i) design, supervision, and project management support to PMU and PIU; and (ii) institutional development, financial and operational improvement support to the PMU and CMC. The consulting firms were recruited using the quality- and cost-based selection (QCBS) method in_accordance with ADB's Guidelines on the Use of Consultants 2010, as amended from time to time.
Procurement Procurements to be financed by the Project will be carried out in accordance with ADB's Procurement Guidelines 2010, as amended from time to time.
