Dewatering is no more about removing excess water from one place or another, it has lot of other challenges like… dewatering sites are generally open to sky, prone to large amount of mud & debris & are often unmanned. Pumps need to be moved to multiple locations & thus need to be easily portable. Pumps movement, fitment & electrical connections are often done by unskilled laborer & thus pumps are prone to damage during its movement or faulty electrical connections. Many a times due to ignorance, omission or un foreseen emergency pumps are put in to operation directly on main supply without using control panel in between. Due to this, pumps are generally exposed to erratic power supply, whether used on electrical supply or supply through genset. Due to all these uncertainties site engineers have to live with frequent breakdown of pump sets due to dry running, single phasing or mechanical jamming.
