Abstract
The main objective of the research is to conduct water conservation efforts through the
application of rainwater harvesting technology as an alternative of city gardens water resource
by utilizing flyover bodies as water catchment areas, where so far the rainwater that falls on the
road pavement is not accommodated and only allowed to permeate or enter the drainage
channel. The research approach method used is to implement the integrated of flyover bodies
management with an environmental perspective (ecodrain) by accommodating, absorbing,
flowing and maintaining excess water in order not to cause pool and danger to the environment
using Rain Cycle 2 aid program with input data consist of: the effective catchment area (m2),
the amount of annual daily rainfall (mm/year), drainage coefficient and water requirements
(m3/day). The main results of the study stated that the results of the optimum reservoir size that
could be constructed were approximately 385 m3, which was divided into seven reservoirs with
a size of 55 m3 each with the dimensions of the reservoir (length, width and height of the tank)
16.22 m, 4 m and 1 m respectively. The rainwater harvesting produced contribute
approximately 7.7% to 19% or equivalent to 9.24 m3 to 22.8 m3
