Here are a few things you should take care of.
No matter where you live, you’ll find rainwater and groundwater accumulated at some places around. This is a natural phenomenon and you can’t limit it. It happens everywhere and people aren’t bothered unless they are getting directly affected by the same. I mean if you don’t have to cross the place or go for construction, this shouldn’t bother you. But, if you have to go for construction at the same place then it should be a cause of worry. That’s where dewatering comes in.
What is Dewatering?
Dewatering means removing the water from solid material or soil by wet classification, centrifugation, filtration, or similar solid-liquid separation processes such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes. In construction the water is pumped from wells or sumps to temporarily lower the groundwater levels, to allow excavation in dry and stable conditions below natural groundwater level. Many dewatering companies have come into existence since the need for dewatering has gone up.
However there are a few things that must be taken into consideration before going for dewatering in the UAE. Every place has its rules and regulations one must comply with. As far as the UAE goes, here are the ten important things to consider for dewatering :
Things to look before proceeding for a dewatering of your building or land in Dubai.
Understanding The Type Of Land.
Before you go for dewatering it is highly recommended to get the type of land checked. This helps you in knowing what procedure you should go for to get the most favorable results.
Understanding The Water Table Condition.
Just like knowing the land type, it is equally important to understand the water table condition of your area else all your hard work and efforts will go in vain. In many areas, the water level usually remains high means you can’t take that down by any means. Hence it is recommended to know the water table cycle of your area.
Before you start your work on dewatering make sure to check if you need any permissions or permits for doing the same or you can land yourself in trouble.
Choosing The Right Pump.
One thing you must keep into consideration is that not every pump can be used for every water type. I mean you can’t be using a single pump for every type of water. Just like there are different medicines for different diseases, similarly, there are different types of pumps used for dewatering different types of water dewatering like floodwater, rainwater, sewage bypass or groundwater.
Discharge Of Water.
Make sure that you never discharge water that has been contaminated with oil, grease, or chemical products directly as it can be extremely dangerous for the dewatering workers. Their safety should be your utmost priority. You can however choose an oil/water separator for the job.
Soil Erosion / Instability Check.
Soil erosion is one of the biggest problems when it comes to construction. Hence if you want your dewatering to be successful, make sure that you take the necessary measures for controlling the erosion.
Right Method / Technique.
This is the key. When all the other conditions are favoring you, make sure that you choose the right method or technique for dewatering in Dubai. This won’t just save your time and efforts but will also prevent you from redoing the work.
You can also make use of the dewatering bags for the job. Though this isn’t something that can be used for dewatering huge spaces. But this is very relevant as far as the dewatering goes.
Dewatering Bags, also known as sediment filter bags or silt bags, are an easy and economical option for any site looking to remove sediment or silt from their discharge. It is made from a robust geotextile filter fabric to catch and contain sediment as it is pumped from your site.
This is also one of the most important things you should take care of. You must be very sure about the right weather for dewatering. If not paid much attention it might lead to wastage of resources and efforts.
If the water accumulated isn’t very much, you can use sump pumps for dewatering the space. Sump pumps are small pumps that channel water away from sump basins. They are mainly of two types:
a) Submersible sump pumps which are totally hidden in your sump basin.
b) Pedestal sump pumps which are mounted above floor level on columns that protrude out of the sump basin.
These were some of the important things you needed to know about dewatering . Make sure that you take care of them for better results.
