A sand point well has some disadvantages. These include:
• Limited water supply - Sand point wells are usually shallow, so access to large amounts of groundwater is limited.
• Poor water quality - Contamination from surface runoff and other sources can contaminate the well’s water.
• Maintenance needs - The filter screen may become clogged with sediment or debris, requiring frequent maintenance and cleaning.
• Costly installation - Installing a sand point well requires specialized equipment and expertise which can be expensive.
Overall, these drawbacks make it difficult for homeowners to use a sand point well as their primary source of drinking water without additional treatment methods in place to ensure its safety and reliability.
