Maintenance and Well Reactivation

Maintenance and Well Reactivation

Continuous maintenance can extend the life of a water well while also increasing the flow of the water well. The processes help to preserve the value of your well on a long-term basis.

​​​Water wells require regular  maintenance  to ensure adequate  water  flow and optimum  water  quality. As a  water well  ages, the rate at which  water  may be pumped (commonly referred to as the  well  yield, flow or performance) tends to decrease, especially in wells that were not properly developed when first drilled.

As a water wells ages, however, the maintenance, repair and replacement of the associated infrastructure required to maintain the expected reliability becomes a pressing concern

In order to maintain sustainable water well productivity, it is of utmost importance to maintain and treat it in periodical basis. Only thus can durability and sustainability be ensured and investments secured for a long time. Consequently, well maintenance program helps clients to ensure the working order and performance of their wells on a long-term basis. This drive for innovation continues as we enhance SUPRA maintenance and well reactivation portfolios.

The main components of a well maintenance program include:

Condition assessment

Data collection and assessment

Well inspection and testing
 

Our Approach for Water Well Maintenance and Services

Mechanical and Air-Surging

After the screen and casing are constructed, the well is then developed by a surging process surging tools augmented with pressured air. This technique can remove much fine material from the screen and formation area.

This proscess is then coupled with chemical additives that help to break down bentonites that prove resistant to removal and greatly enhances the mechanical efficiency of the well.

Over-Pumping and Backwashing

Pumping a well at a higher rate than it was originally designed is one of the easiest methods of removing fine materials from the aquifer. When followed with other development procedures, overpumping can stabilize the aquifer.

Back washing procedures involve the intermittent reversal of the flow of water into a well. The turbulence created by alternately pumping the well and allowing the water in the pipe to re-enter the aquifer assists the development procedure.

High Velocity Jetting

One of the most effective methods of well development involves the use of water jetting at high velocity onto and through the screen. The forceful action of the jets working out through the screen Opening agitates and rearranges the formation surrounding the screen. This method also may correct the damage to the formation resulting from drilling
