Dewatering Planning Documents: What Needs to be Included
- Written by Whats On Australia
When constructing or excavating in water-logged regions, if the right technique or process is not employed to reduce the amount of water found in the construction site, the structure that will be erected will encounter faults and, in a time, sink or collapse. One common technique employed when constructing in water-logged regions is dewatering. This technique helps to ensure that a strong and studious structure is constructed.
What is dewatering?
Dewatering is a process that involves the removal of water from a construction site. It ensures that the excess groundwater is reduced to the natural amount of groundwater found in normal regions. The excess water is removed by either:
-
* Pumping using water pumps
-
* Evaporation
-
* Filtration
-
* Centrifugation
-
* Filter press
-
* Or solid-liquid separation processes
Why is the purpose of dewatering?
The process of dewatering is performed before excavation or shoring to aid in the following.
-
* Provide a dry environment for excavation and construction
-
* Reduce the risk of damaging construction equipment
-
* Helps reduce the lateral load on sheeting and bracing
-
* It reduces the risk of polluting marine life when constructing mating structures
-
* It makes the construction environment suitable and conducive for working
How to create a detailed dewatering plan
When constructing a structure in a water-logged region, it is vital to ensure that the structure is not affected by the excess water present. It is also important to have a good dewatering plan in place. Poor dewatering will result in such structure collapsing and giving the construction firm a bad image. A good dewatering plan focuses on some key factors, and they are:
-
The nature of the soil
-
The region where the construction will occur: This considers whether the region is a river, marsh, ocean, or sea
-
The equipment needed and those available for dewatering
This is a comprehensive guide on how to create a reliable dewatering plan.
-
Identify the site region that needs dewatering and choose a suitable spot for discharging the excess water.
-
Based on the construction site and the amount of water present on the site, choose a suitable dewatering method minimizing environmental impacts.
-
Assess the possibility of reusing the excess water.
-
Study the water table condition In the region to aid your choice of discharge location
-
Do not discharge excess water directly into slopes.
-
Enquire about the dewatering laws and rules governing that area.
-
Ensure that your dewatering technique is in line with the rules: This entails ensuring the amount of water discharged is permitted by the dewatering governing body.
-
Avoid direct discharge of contaminated water into the environment.
What does a dewatering plan need to include?
For a reliable and quality dewatering plan. Ensure that the plan contains the following details:
-
The existing location of water.
-
The proposed location for discharge.
-
An approximate total volume of water
-
The quality of water present in the area. This should contain the pH, conductivity, and if it is contaminated or not.
-
Summary of the water treatment table.
-
Proof of work area like pictures.
-
A digital signoff.
Conclusion
In general, a dewatering plan is ideal in ensuring that the right dewatering technique is employed by following the dewatering laws governing a particular region while ensuring that the structure being constructed is of good quality. Dewatering plans are an essential document for companies that perform dewatering projects, such as fuel system civil engineering contractors.
