Water Financing Partner FacilityPILOT AND DEMONSTRATION ACTIVITY

 Activity Title: Adapting Appropriate Sanitation Solutions to Peri-Urban Areas in Viet Nam : APDA After Care Support

Proposer: NGO-EAST Viet NamRequest Date: 27 July 2009Country: Viet Nam Region: Southeast Asia

 Activity Proposed Start date: 1September 2009

 Activity Proposed duration: six months

Cost Estimate: US$ 10,000 ADB Activity Officer : Hubert Jenny, Senior Urban Development Specialist, SEEW

I. Background

1. In April 2008, the NGO EAST Vietnam launched a Pilot and Demonstration Activity(PDA) on Developing Appropriate Sanitation Solution for Peri-Urban Areas in Viet Nam. Itfocused on decentralized wastewater treatment models to be replicated in other locationswith similar context. It foresaw, among others, the implementation of a pilot treatment systembeing able to handle domestic wastewater disposed of from around 50 households. Basedon DEWATS (decentralized wastewater treatment) technology, the system consists of aseries of complementary treatment components combined with a separated networkcollecting black and grey water.

2. In February 2009, the pilot treatment plant was completed and handed over to thecommunity, in charge of its management, operation and maintenance. EAST Vietnam

proposed within the PDA a model for local management and its financing mechanisms.However, these responsibilities are new to the community and thus requires technicalsupport. Moreover, the system management will need further fine tuning to fit, as closely aspossible, the local context and the technical requirements.

3. Besides, the partners of the project are now willing to extend the coverage of theactual pilot treatment plant during the year 2010 under the financing of IMV (Institut desMétiers de la Ville). Considering the first experiences learned from the PDA, the partners willpreferably opt for a combined system using existing infrastructures. However, like the actualslope between others households and the DEWATS is too low, a survey must be done todetermine an appropriate solution to optimise the DEWATS functioning.

II. Objectives

4. The main objective of the first PDA was to develop technical, management andfinancial systems for peri-urban areas, for replication and scaling up in other peri-urbanareas. Taken into consideration that the coverage area will be soon extended throughanother type of collection system, this technical assistance aims at evaluating and improving,if necessary, the model developed by the PDA earlier. It will refine the management,operation and maintenance (O&M) system as well as the financing mechanisms already setup through the PDA, thus ensuring sustainability of the project. Thanks to the lessons

learned through the PDA, the technical assistance will permit to select the better kind ofwastewater collection system to be applied in Viet Nam’s peri-urban areas.

III. Scope of work

5. The scope of work focuses on Monitoring and Evaluation (M&E) of the actualmanagement, O&M system, the financial mechanisms and the technical choices already setup through the PDA. Therefore, it will include several field trips, surveys, analysis andmeetings with the local representatives to support them in their responsibilities. In addition,the scope concentrates on the evaluation of the opportunity of combined collection systemrelated to the technical choices made within the pilot treatment plant and its collectionsystem.

IV. Detailed activities

A. M&E of the management, O&M system and f inancia l mechanisms

6. The data required for this M&E work will be mainly gathered through field trips andmeetings with the local representatives and the residents. Moreover, effluent analysis will bemade as scientific arguments to assess the treatment efficiency. The M&E will do on-fieldassessment of:

(i) Separate systems;

(ii) Actual quantitative and qualitative O&M requirements;

(iii) Financial management and accounting issues.

7. From these data, the usual terms previously set up by the PDA might need to beevaluated and adapted to the actual context taking the extension phase into consideration.From this work, a small document can be elaborated which would specify the management,

the O&M modalities and the responsibilities of each actor. It would be communicated to theresidents for a better involvement, thus ensuring a sustainable functioning of theinfrastructures.

B. Surveys on benef ic iar ies ’ sat isfact ion

8. As a pilot system, the DEWATS of Kieu Ky needs to be more deeply evaluated, inorder to optimize the technical functioning of other projects. The pilot plant is community-based project. Then, its evaluation might also come from the beneficiaries. A survey onresidents’ satisfaction is necessary to:

(i) Identify positive or negative effects such as bad smells, landscape valorisation,salubrity of the neighbourhood, etc;

(ii) Assess the suitability of the model proposed by the PDA, all terms considered.

C. Evaluation of the opportunity of combined collection system

9. Contrary to what was initially recommended in the PDA, the extension phaseforesees to use the existing combined sewer. However, the actual slope between othershouseholds and the DEWATS is too low, also a survey will be done to determine anappropriate solution like the use of a wastewater’s pump.

(i) Effluent quality and quantity analyzing to assess the efficiency of the treatment plant;

(ii) Survey about utilization of a wastewater’s pump;

(iii) Evaluation of the capacity of the DEWATS’operator to manage a wastewater’s pump.

V. Implementation Timetable

10. This PDA-after care support is expected to be completed within six months, startingSeptember 2009 and ending in February 2010.

VI. Institutional Management Arrangements

11. Like the first PDA, the management of this proposed after-care support will be theresponsibility of French NGO EAST Vietnam, in close collaboration with Hanoi People’sCommittee and the Transport and Urban Public Works Service (TUPWS), Hanoi People’sCommittee, is responsible for water supply and sanitation issues.

12. Close cooperation between Gia Lam People’s Committee (district level), Kieu KyPeople’s Committee (commune level), and EAST Vietnam will also be set up to implementactivities.

VII. Stakeholders Participation

13. Different stakeholders will take part in the implementation of the activities describedabove:

•  The NGO EAST Vietnam: as the implementing organization, EAST Vietnam will carry outall activities described in Section IV (Detailed Activities);

•  The TUPWS will facilitate the implementation of activities and monitor the project;•  Local water resources experts and technicians will be consulted and involved•  The local communities which have the responsibility for O&M will be closely involved as

well as other collaborating partners who are supporting sanitation-related initiatives inViet Nam

VIII. Expected Results (outputs/outcomes/effects/impacts):

14. This PDA after care support will enable the adaptation of appropriate technologies as well as the O&M arrangements and financing mechanisms to other peri-urban areasin Viet Nam.

15. This will ultimately result in faster replication and scaling up of the model ininvestment projects such supported by ADB and other donors such as in Thanh Hoa City

Comprehensive Socio-Economic Development Project and Provincial Hue Water SupplyProject.

IX. Scope for Replication/Use in Other DMCs:

16. Because decentralized sanitation appears to be the practical approach that could betaken by governments in the Asia-Pacific region, the scope for replicating the findings andrecommendations from this PDA is high. The documentation of lessons learned will be
