A well casing security device and method. The security device includes a cover including a sidewall, a top, one or more stabilizers, and a means for attaching the cover to a well casing or to its concrete slab to render it vandal-resistant. A locking support ring is provided for attachment to either the well casing or to the concrete slab surrounding the casing. The locking support ring includes a ring body with a plurality of braces. Each of the braces includes an arm defining a slot between the arm and the ring body. The cover includes a plurality of brackets enabling rotational engagement cover with the locking support ring. Locking means are provided on the cover to lock the cover to the locking support ring. The locking means includes a key operated lock that is tamper resistant and insures that the well casing cannot be accessed easily by an intruder.

Methods, apparatuses, and computer readable medium including computer program products, are provided for determining the depth of water in a well. A method may include coupling a signal onto a cable connected to a submersible well pump. The method may further include monitoring the cable to determine a first time corresponding to a first reflection of the signal caused by the cable entering a water column between a water surface and the submersible pump. The method may further include monitoring the cable to determine a second time corresponding to a second reflection of the signal caused by an impedance mismatch between the cable surrounded by water and a motor in the submersible well pump. The method may further include determining a water height between the submersible pump and the water surface from the first time and the second time.

The invention relates to a method and means for diluting or concentrating solutions, applied to processes for the desalination of water, characterised by being carried out on the basis of a borehole (4) in permeable coastal land, where two internal wells (5, 6) are installed producing three channels that are interconnected at the bottom, by means of a membrane packet (9), disposed such that the supply flow towards the membranes and provided via the borehole (4) flows in a downward direction, generated, using the principle of communicating vessels, by the suction of a motor pump (7) installed at a shallow depth inside the well of the concentrate (5), with an ascending flow, pouring same to the marine outlet and the diluted flow (permeate) drains to the second well (6), which is hollow and at atmospheric pressure, where a motor pump (8) extracts the permeate for the use thereof. The method can be used for dilution and/or concentration with minimal energy costs, both on land and on the sea bed on a floating platform (11) or cliff.

An apparatus includes a hydrant assembly 102 configured for use with a well casing 900, a pitless adapter 902, and a pump assembly 904. The hydrant assembly 102 includes a water spout assembly 104 configured to be positioned above the ground 906 and also above the well casing 900. A water pipe assembly 106 is configured to be in fluid communication with the pitless adapter 902, the pump assembly 904 and the water spout assembly 104. This is done in such a way that water flows from the pump assembly 904, past the pitless adapter 902 and toward the water spout assembly 104 once the pump assembly 904 is activated. A pipe-support assembly 108 is configured to be positioned relative to the well casing 900, the pitless adapter 902 and the pump assembly 904. The pipe-support assembly 108 is also configured to selectively spatially position and support, at least in part, the water pipe assembly 106 relative to the well casing 900, the pitless adapter 902 and the pump assembly 904 in such a way that the pipe-support assembly 108, in use, provides selective spatial positioning of the water pipe assembly 106 relative to site-installation conditions associated with the well casing 900, the pitless adapter 902 and the pump assembly 904, which are installed relative to the surface 905 of the ground 906.
