If you’re dewatering in low-lying areas, be prepared for some formidable challenges. Even a moderate amount of rainfall can cause significant water logging while stormy rains can inundate the areas completely and in a very short span of time. This calls for special preparedness. We at VEMC are one of the leading industrial water pumps dealers in Mumbai, and in this blog we talk about the preventive strategies you need for dewatering low-lying areas.
Difficulties of dewatering flood-prone areas
- Dewatering flood prone areas requires you to be quick on your feet. This is because even a short amount of rainfall could quickly inundate the space giving you very little reaction time.
- Due to high soil saturation, it can be quite difficult to drain away the water from the low-lying area.
- Low-lying areas often have a high water table which can make it quite challenging to dewater it.
- While dewatering the low-lying or flood prone area, there is a risk of continuous inflow of water from the nearby streams, lakes or rivers.
- Dewatering a flood-prone or low-lying area can also have serious environmental concerns as it could lead to undesirable deposition of sediments in the nearby areas.
- Finally, dewatering flood-prone areas is quite a costly affair as it requires the continuous engagement of men, material and equipment.
Proactive measures for dewatering
While the above difficulties may sound rather insurmountable, it is nonetheless possible to effectively dewater a flood-prone area. This is especially true if we follow a proactive strategies like French drains and sump pumps.
- A French drain is made by using perforated pipe buried in a trench that is filled with gravel. It redirects water away from an area and prevents pooling in low-lying areas.
- Sump pumps are effective in areas with a high water table. It is an equipment that helps remove water logged in a sump basin.
The right pumps to choose for dewatering
Dewatering a flood-prone area is quite challenging and hence your choice of pumps must be very careful. We at VEMC offer a wide range of dewatering pumps that can help you deal with the menace of inundation especially if you’re located in a low-lying area. Our Eterna CW/BW series for instance is a market leader thanks to its powerful performance, massive capacity and robust design. It offers a head of up to 70 meters and is specially suited for dewatering trenches, pits and foundations. It has especially found enormous use during the monsoon season, and has been a favourite of municipalities, builders and mall-owners.
However, in case flooding is frequent, it is best to go with permanent dewatering systems. These provide continuous drainage using systems like:
- Subsurface drainage systems
- Deep well dewatering systems
- Interceptor drains
- Tidal gates and flood barriers
- Stormwater management systems
- Retention and detention ponds
