Well blockages can cause a variety of problems, including water supply interruptions and pump damage. Well cameraing is an effective way to assess the condition of a well and identify blockages. In this guide, we will review the most common types of well blockages, methods for identifying and resolving them using well cameraing, and steps for preparing a well before cameraing.
The most common types of well blockages
- Accumulation of organic matter
- Symptoms: Reduced water flow, pump problems.
- Causes: Algae, bacteria, plant remains.
- Mineral deposits
- Symptoms: Decrease in water pressure, difficult operation of the pump.
- Causes: Calcium, magnesium and iron oxides.
- Sand and mud
- Symptoms: Turbid water, rapid pump wear.
- Causes: Sandy or silty soil layers.
- Collapse or crack in the wall of a well
- Symptoms: Sudden decrease in water flow, pump damage.
- Causes: Structural damage over time, poor installation.
- Foreign objects
- Symptoms: Complete cessation of water flow, pump shutdown.
- Causes: Entry of debris, tools, animals.
How can they be identified and resolved using well cameraing?
- Accumulation of organic matter
- Identification: A well camera can be used to observe greenish or brownish deposits on the walls of the well.
- Solution: Chemical cleaning or mechanical cleaning with high-pressure water jet.
- Mineral deposits
- Identification: It can be seen on camera footage as a whitish, hard layer on the wall of the well.
- Solution: Treatment with acid to dissolve deposits, followed by rinsing.
- Sand and mud
- Identification: The camera shows the sandy or muddy layers at the bottom of the well.
- Solution: By pumping or installing special sand filters.
- Collapse or crack in the wall of a well
- Identification: Structural damage and cracks are clearly visible during the camera shooting.
- Solution: If necessary, install a new casing or reinforce the well walls.
- Foreign objects
- Identification: The camera clearly shows the presence of foreign objects.
- Solution: Removal with special tools, such as pliers or a magnet.
How to prepare the well before well cameraing?
- Preliminary water level measurement: Measure the water level in the well and record it.
- Water quality control: Perform a water quality test to identify potential contaminants.
- Pump removal: Remove the pump so that the camera can move unhindered in the well.
- Preliminary cleaning: If possible, remove any larger dirt or debris from the well.
- Creating a camera plan: Let's make a plan of the steps of filming and any equipment that may be needed.
