Simply put, dewatering is the process of eliminating or removing water for the purpose of ensuring a smooth operation of construction or engineering work. Many firms have to decide on whether to purchase a dewatering pump or hire one. Hiring pumps can be a quick and easy solution when a firm is not prepared to incur capital expenses for the exercise.
Most firms that have construction or engineering sites, prefer to rent dewatering pumps to remove ground water. There are several reasons to employ a dewatering pump. They may be used to lower the water table, lay foundations, create space, or even for shoring.
Setbacks to Dewatering:
Some of the major setbacks to dewatering include a heavy downpour or freezing. Consistent heavy rains usually hamper dewatering work though in some cases, tracked machines may be used in the operation. In cases of heavy snow during winter, groundwork is stopped. Temperature changes may also affect dewatering work. Increase in temperature will increase the water table.
If you opt to purchase a dewatering pump, you may not appreciate the seasonal changes in the environment that are important in choosing a dewatering pump. Pump rental specialists are versed in the knowledge with regard to climatic changes and can advise which dewatering pump will work best for each season.
Types of Pumps for Dewatering:
The type of pump used may vary depending on the size of the project. Super silent diesel pumps are used where noise should be kept at a minimum. In areas where noise may not be an issue, standard diesel pumps may be used. In areas near an electrical supply, electric submersible pumps can be used.
Most dewatering firms have their own generators, therefore power on-site may not be an issue for them. They normally carry out a survey of the site prior to deciding how to conduct the dewatering. Some factors considered during a survey include the required flow, stand-by unit requirements, distance, frequency of running the pumps, and duration of the hire. This will facilitate the provision of the ideal equipment from the specialist supplier.
Dealing with Emergencies:
Pump hire experts have enough back-up in cases of need for additional equipment. They also provide 24/7 emergency response that ensures the project is carried out within the set time frame. Emergencies may include equipment failure or problems encountered during the exercise. With an emergency response in place you will be able to also avoid fines that result from failure to complete the project.
