Management strategy of sustainable urban drainage in Pekanbaru City

Abstract

The rapid growth of population and development has changes in the land use. A lot of opened land or forest has changed into the settlement or industry. This change had made the power of absorption function becomes low instead the surface run off which results in shorter time water retention so that accumulation of collected rainwater exceeds the existing drainage capacity. The basic concepts of sustainable drainage development is increasing the use of water, minimizing losses, improving and conserving the environment. Drainage management model developed is using eco drain approach, which is an integrated and comprehensive approach and incorporates ecological or environmental factors in every drainage management effort.
