A method of operating a septic system to facilitate maintenance and avoid damage to property and/or the environment. A septic system that collects and monitors data to provide information to a user about the nature of a problem condition, or to warn a user of potential problems in advance, or to recommend courses of action to avoid costly repairs, or property damage, or damage to the environment.

An ingress device assembly is configured to be used with a septic tank that has a chamber and an access opening and a riser extending from the chamber. The ingress device assembly includes a connector including a flange including a first section and a second section cooperatively defining a perimeter of the connector and an inner bore configured to align with the access opening, the first section having a first interlock feature and the second section having a second interlock feature engaged with the first interlock feature; and an ingress device removably and rotatably coupled to the connector, the ingress device including a body configured to extend across at least a portion of the access opening.

A stand-alone toilet system is powered by photovoltaic cells to operate a dehumidifier from which water is extracted from the atmosphere by dehumidification and used for flushing; an electronic compressor is situated in the toilet tank to compress air which is used with water in the flush cycle; a motorized or hydraulic hinge is utilized to open and close a toilet cover automatically which can be locked in place by electromagnet means to create an airtight seal in the closed position; a heating element and a UV lamp are situated inside the “treatment facility” of the toilet system to evaporate liquid and sanitize waste content therein respectively.

An insulating disc can be easily installed and removed from inside a riser of a septic tank. The insulating disc is seated atop an opening of the tank lid and seals around the riser inner surface. The disc can include a core formed of R-10 extruded polystyrene sandwiched between two layers of high-density polyethylene. A flexible gasket can extend outward from the disc to seal against the inner surface of the riser. Retention tabs can also be provided to center and hold the disc in place. The disc can be divided into two semicircular halves that are hinged together. A hook, eyebolt and/or rope can be used to aid in removing the disc from the riser.

Storage tanks, for example, underground septic tanks, and their methods of fabrication are provided. The tanks include a substantially liquid impermeable plastic vessel having a top, a bottom, and sides; a concrete container encasing and retaining the plastic vessel, the concrete container contacting the bottom and at least partially contacting the sides of the plastic vessel; and at least one opening for receiving effluent, for example, waste effluent, into the plastic vessel. The methods of fabricating the tanks include positioning a plastic vessel into an enclosure; introducing concrete into the enclosure about the plastic vessel; allowing the fluid concrete to cure to provide a substantially solid concrete container about the plastic vessel; and removing the plastic vessel having a concrete container from the enclosure. Vessel shape retaining devices are also disclosed. Aspects of the invention are uniquely adapted to underground storage.
