An Innovative Approach on Urban Drainage Engineering and Management in A
Coastal City – A Conceptual Design for The City of Manado, North Sulawesi.

Abstract
This research exposes the existing condition, the current and potential problems of Manado
urban drainage system. Using qualitative descriptive methods which make use of in depth
interviews to several experienced and resourceful informants, a comprehensive review of the
engineering, management and environmental aspects of the current system is carried out. It
covers all implementation stages of the system, starts from the planning and design,
construction, operation and maintenance and end with the monitoring and evaluation. It
further identifies the actors or agencies which are deemed responsible for the execution of
each of the implementation stages. A quick estimate on the hydraulic capacity and efficiency
of the present main drainage culvert is also carried out to portray any technical problems
occurring within the system. Identification of present and upcoming demands of an integrated
sustainable urban drainage engineering and management of the city is considered. The
process takes into account any master plans available for the city‘s drainage system, the
strategic plan of the city itself, projection and trend on the city‘s economic development, the
prediction of population pressure as well as the trends in people‘s lifestyles which might
effect the management of drainage system in the future.
Several engineering and environmental approaches are evaluated to come up with an
innovative scheme specifically designed for the unique coastal city of Manado. This includes
the presentation of modified frameworks for each of the implementation stages of the urban
drainage system. It also outlines the roles and interests interaction among the responsible
actors or agencies in the implementation of the drainage system and all the stakeholders who
are genuinely interested in the existence of an integrated sustainable and maintainable urban
drainage system.
Keywords: innovative approach, strategic plan, urban drainage system.
