The revised objective was more measurable. There was a results framework in the Project Paper at restructuring which spelled out a logical causal chain between the activities financed by the project and the achievement of the revised objectives. Financing components in wastewater, drainage and technical assistance should lead to increasing the collection of wastewater and reducing the incidence of flooding. Technical assistance and the financing of institutional strengthening were intended to support the sustainability of the achievements. The Additional Financing was intended to ensure that there would be sufficient financial resources to attain the revised objectives. The objective of financial sustainability was mainly supported through the establishment of a tariff, though the project team maintained that the entire technical assistance component was for institutional strengthening and improving efficiency in the sector. The Additional Financing made it likely that there would be enough financial resources to attain the revised objectives.
