  • Water well stagnant bottom rehabilitation means and method
    Patent number: 6138750
    Abstract: An apparatus and method of rehabilitating the stagnant bottom of water wells using existing well equipment including a pump and a pressure tank, augmented by valves and a conduit that extends from the surface to near the bottom of the stagnant region at the well bottom. Water pumped from the well is returned under pressure to the well bottom where it displaces the fouled contents of the stagnant region at the well bottom. This elevates the contents of the well bottom to a position above the pump intake, where the contents can then be pumped to waste.
