CERTIFICATION OF APPROVAL WATER QUALITY ASSESSMENT ON TREATMENT TRAIN SYSTEM FOR STORMWATER RUNOFF

The Stormwater Treatment Train is a mechanism in which runoff water was treated
prior to discharge into the waterways. In the treatment train, the use of the column, serving
as a bioretention system, it would be used to extract small particles, removing the pollutant
by using the drainage water that was infiltrated through the soil. The purpose of this study
is to analyses the water quality efficiency of vegetation plant variation in the treatment train
system for the management of stormwater runoff. The author must therefore measure the
consistency of the water in the column study method, which must be determined by pH,
Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved
Oxygen (DO), Ammonia and Total Suspended Solid (TSS). In this analysis, two species
of vegetation, Jasminum sp. and Cordyline fruticose sp. were selected.
