A study of the total suspended solids TSS discharging into surrounding waters for a small city indicates that 35% of the TSS can be removed by street sweeping, 14% of the TSS can be removed using catch basin inserts and 17% of the TSS can be removed by providing vegetative buffers (grass and parkland) which filter the stormwater runoff. If 450Lb of solids were collected from catch basin inserts after six weeks, how many pounds of solids would you expect the street sweeper to collect over the same period of time?

Landfills

The landfill is a site used for the disposal of waste materials. The landfill is a solid waste facility that is often known as a dumping ground. The image below shows a landfill site in Hawaii. Landfilling is the most ancient and common method used for the disposal of waste. For the landfill, a deep trench is constructed in an isolated place away from the city. The trench for landfills is designed properly after analyzing the total population and the waste generation per capita. The waste is dumped into the trench and after every layer of waste, a layer of soil is spread on the top of it.
