    About this ebook

    For years, the lands in Cameron Highland have been opened and leveled for agricultural farming and intensive crop production. The overall agricultural coverage is relatively small and is mostly done on steep slopes. The high usage of fertilizer and pesticides by local farmers, accompanied by the increase in the frequency of major storm events had given rise to high levels of soil erosion and environmental pollution. In this study, a guideline has been stablished to be used by the local authorities and farmers to conserve soil, protect the natural waterways and the surrounding environments from man-made pollutions.

      CHAPTER I:

      INTRODUCTION

      1.1   GENERAL INFORMATION

      An increasing population due to urbanization contributes to the generation of increased amounts of rubbish and waste material. The uncontrolled dumping of rubbish can exert a huge impact on aesthetics and river water quality, both of which affect the quality of life in urban environments and increased management costs. The rising awareness of these factors has led to the implementation of gross pollutant management strategies as a holistic approach to water quality improvement (Q. Zhang et al., 2014).

      Due to rapid and uncontrolled development in Klang Valley, Kuala Lumpur generate 3,500 tonnes of domestic and industrial waste a day and the cost of public cleansing and waste management is a whopping RM325mil a year, according to statistic from Public Cleansing Management Corporation (SWCorp)(The Star, 2016). The Department of Irrigation and Drainage reported that daily cleaning of log booms along the 110km stretch of the Sungai Kelang basin as part of the River of Life (RoL) project DID collects and disposes of between 10 and 13 tonnes of rubbish accumulated at its 10 log booms and 396 gross pollutant trap (GPT) in a month (The Star, 2018).  An average total of RM500,000 a month was spent to maintain and clean the GPT.  These accumulated pollutants are not only aesthetically unattractive, but also demonstrate environmentally threatening and devastating effect to the natural equilibrium, and impede the hydraulic performance of the urban drainage system (Ghani A. et. al., 2011). 

      There are a large number of factors which could affect the number of gross pollutants in stormwater. Among the influential variables which may influence gross pollutant loads includes catchment characteristics (a type of land use, population density, and affluence), rainfall characteristics, management practice (such as street sweeping/vacuuming, availability of collection bins and regularity of cleaning, recycling programs) and education and awareness programs.

      The rising awareness about the degradation of river water quality by gross pollutants
