The present invention relates to a block coupler for connecting block to block for septic tank and water treatment facility. The block coupler according to the present invention comprises a body having a flow path therein; an inflow part having an inflow hole formed on one side of the longitudinal ends of the body so as to communicate with the flow path; an outflow part having an outflow hole formed on the other side of the longitudinal ends of the body having the inflow part so as to communicate with the flow path; and a connecting part provided at the outer end of the body having the inflow part so as to prevent the body coupled to the block from being separated.

A septic system is provided that includes a septic tank having a plurality of compartments with a tank inlet in a first compartment. First and second vaults are positioned in a second compartment. The first vault receives fluid from the first compartment at a level near a fluid surface in the tank. A first flow inducer receives fluid from the first vault at a level near a bottom of the first vault, and releases fluid into the second compartment at a level near the fluid surface. The second vault receives fluid from the second compartment at a level near a bottom of the second vault and discharge fluid at a level near the fluid surface. Third and fourth vaults and a second flow inducer are positioned in a third compartment, the third vault receiving fluid from the second vault, and the fourth vault discharging fluid to a tank outlet.

A holding tank system for holding a waste, the holding tank system including: a holding tank including a floor disposed in a first plane, the holding tank configured to be supported on at least one joist disposed in a second plane, wherein the second plane is disposed at an incline with respect to the first plane.

Disclosed herein is a free-standing cesspool and a cesspool liner that may be used to retrofit existing cesspools in order to provide additional storage and/or processing for raw sewage before the sewage leaches out of the cesspool.

A safety grating has an arch shape cross section and is useful within a riser having a frusto-conical shape wall which riser is attached to a septic tank or another structure. The grating comprises a hub and radially extending arms, one or more of which is rotatable relative to the hub length at a hinge joint, to decrease the size of the grating and enable installation of the grating by passing the grating a smaller end opening of a riser.

A molded basin for use with a submersible sump, sewage or grinder pump. The molded construction of the basin permits design improvements to be incorporated into the basin including bolt down slots in a bottom flange of a bottom of the basin, a molded inner basin mounting surface for a float tree, a molded inner surface support mount to receive a bracket of a rail system used to raise and lower the pump within the basin, a disc that fits within the basin and is supported by a molded inner facing horizontal rib to create a wet/dry well and structural features present in a top surface of the basin and a cover for the basin to close said basin. Extension risers may be added to extend the height of the basin, wherein the extension risers contain many of the same structural features that are present in the basin.
