In the case of harbor areas, such siltation reduces the depth of the water body and therefore creates a major problem for the free sailing of large vehicles. It must be mentioned here that large sea vehicles require a certain depth in order to be able to navigate properly. Siltation has been the cause behind the failure of initially flourishing harbors since time immemorial. The deteriorating conditions of many harbors have even forced people of many coastal cities and towns to abandon their homes and relocate to a place which has better navigation facilities. In the case of rivers, the consequences of siltation are equally grim, if not more. The increase in the height of the riverbed can cause the rivers to overflow if there is too much rain. In many areas of the world heavy showers during the monsoons cause the rivers to overflow and flood the banks, thereby, endangering thousands of lives and properties. History depicts that this has actually endangered the sustenance of certain civilizations in some parts of the world. Thankfully, with the advancement of science and technology, human kind has become able to arm itself against such natural calamities. Now, there is a process to fight the effects of siltation and it is called dredging. While this process has reduced the harbor of drying up and rivers overflowing, experts opine that dredging can also reduce the threat on some marine life in certain coastal areas around the world. Of course, this heavy weight process could not be carried out successfully without the help of Stationary Concrete Pumps, High Pressure Dewatering and Slurry Pumps and Sprayed Render and Plaster Pumps. Nowadays, various kinds of Mud Dredging Pumps are available. While previously they were used only in industrial sectors and by government authorities in charge of dredging the harbour areas and rivers; nowadays they are even hired by common people mainly for dredging ponds and keeping them clean. Even a few decades back the Trailer Mounted Concrete Pumps were not considered to be very environment friendly as they used up a lot of fuel and created more pollution through noise and smoke than what they dredged up from the bottom of the water body. However, the latest models are far more efficient than those. They are not just eco-friendly, but are affordable and durable too.
