Well sand removal

Sand in the water can damage a pump and may indicate problems with the well screens or filter pack.

Sand at a tap or in the pressure system can indicate a clogged screen or a damaged filter pack. Sand removal includes extracting accumulated sand and silt from the bottom, cleaning the casing and screens, and assessing whether the graded gravel pack needs restoring. Gravel size is selected to suit the aquifer material.

After the intervention, we develop the well and perform a pumping test to remove remaining suspended particles and check the result. Reducing the sand reaching the pump helps protect the pump and pressure system and can extend the life of the installation.

• Sand and silt extraction from the well bottom
• Casing and screen cleaning
• Restoration of the graded filter pack when needed
• Well development after intervention
• Protection for the pump and pressure system
