Rapid development in a watershed affects surface and ground water sources. urbanization results in an increase in surface runoff and the volume of water that collects downstream of the watershed. best practice for water resources management is low impact development such as bioretention, vegetated roofs, rain barrels, vegetative swales, permeable pavements, and rainwater wetlands have been applied to reduce the adverse effects of urbanization such as flooding by reducing peak flow in the area. surface and thereby managing rainwater runoff. The aim of this study is to investigate the quality of wastewater originating from drainage canals. The research was conducted in Kali Item, Sunter North Jakarta Indonesia. The filter material used are vegetative soil, Quartz sand, zeolite, charcoal, pumice, and palm fiber. The research was conducted in two steps. The first step is to make a water treatment installation with a filtration system and the second steps of sample testing in the laboratory. Analysis of the data used is descriptive analysis. The results of the study show a physical analysis of water and chemistry analysis. The artificial bioretention tank consists of a watertight plastic cylinder measuring diameter 670 mm and height 800 mm with a filtration media of 50-60 cm high inside the box, leaving 20 cm to provide space and time for standing water during infiltration/absorption. The bioretention tank is equipped with an automatic water pump (electricity). The artificial bioretention will overcome the quality water of river water to obtain some clean water requirements Government standard. The water hardness and watercolor content still meets the requirements from Permenkes No. 32/2017 about Environmental Health Quality standards for Water Media for Sanitary Hygiene Needs. The water turbidity has not met the requirement, and pH water still meets the physical properties of drinking pH water. [ABSTRACT FROM AUTHOR] |
