Water Well Seal

A water well system, the system comprising:

• a well casing configured to extend vertically downward below a ground level;
• a water supply line;
• a water pump configured to:
• connect to the water supply line;
• draw in a flow of water from a volume of aquifer water within the well casing;
• and
• supply the flow of water to the water supply line;
• an electrical power line configured to be connected to the water pump;
• and
• a seal configured for use within the well casing, the seal including:
• a rigid body including a lumen extending vertically through the rigid body and configured to enable connection of a water supply line therethrough;
• a cylindrically-shaped expandable seal membrane connected to the rigid body;
• a bladder defined by and between the rigid body and the expandable seal membrane;
• and
• a bladder fill port connecting and enabling flow of water between the bladder and lumen;
• and
• wherein the expandable seal membrane is configured to expand outwardly when head pressure within the bladder is elevated as compared to an ambient air pressure;
• and
• wherein expansion of the expandable seal membrane is configured to force the expandable seal membrane outward against an interior surface of the well casing of the water well.

A method for utilizing a seal within a water well, the method comprising:

• disposing an assembly within a well casing of the water well, the assembly including:
• a water supply line;
• a water pump connected to the water supply line and configured to draw in a flow of water from a volume of aquifer water within the well casing and supply the flow of water to the water supply line;
• an electrical power line connected to the water pump;
• and
• the seal including:
• a rigid body including a lumen extending vertically through the rigid body and configured to enable connection of a water supply line therethrough;
• a cylindrically-shaped expandable seal membrane connected to the rigid body;
• a bladder defined by and between the rigid body and the expandable seal membrane;
• and
• a bladder fill port connecting and enabling flow of water between the bladder and lumen, wherein the expandable seal membrane is configured to expand outwardly when head pressure within the bladder is elevated as compared to an ambient air pressure and wherein expansion of the expandable seal membrane is configured to force the expandable seal membrane outward against an interior surface of a well casing of the water well;
• and
• positioning the assembly within the well casing at a desired vertical location;
• activating the water pump to expand the expandable seal membrane against the well casing;
• and
• utilizing the water pump to provide the flow of water through the water supply line.
