The invention relates to a sewer rehabilitation method, wherein a rehabilitation tool (5) is introduced, by means of a robot (2) that can be moved in a sewer main line (3) of a sewerage system, into a house sewer line (9) leading into said sewer main line (3), rehabilitation work is carried out in the house sewer line (9) by means of the rehabilitation tool (5), and the rehabilitation tool (5) is removed from the house sewer line (9) by means of the robot (2) once rehabilitation work is completed. The aim of the invention is to provide a viable and cost-effective sewer rehabilitation method and corresponding system enabling sewer rehabilitation work being carried out in the house sewer line (9) starting from the sewer main line (3). For this purpose, the robot (2) picks up the rehabilitation tool (5) and transports it through the sewer main line (3) to the mouth of the house sewer line (9), introduces the rehabilitation tool (5) into the house sewer line (9) and puts it down, advances the rehabilitation tool (5) in the house sewer line (9) up to a defective point (10) and retracts the tool from the house sewer line (9) and picks it up again once rehabilitation work is completed. The invention further relates to a sewer rehabilitation system comprising a robot (2) that can be moved in a sewer main line (3) of a sewerage system and a rehabilitation tool (5) that can be introduced into a house sewer line (9), the robot (2) having a remotely controllable gripping member (4) with which the rehabilitation tool (5) can be gripped.

The method of the managed sewer is a Netcentric distributed process that is managed in real-time and implemented through several apparatuses that enable the low capital cost and low installation cost of a smaller diameter pipe (smaller than typically used in gravity flow systems). The apparatuses enable the method of managing the grinding, pumping and staging processes to optimize the effectiveness of the collection process through the small pipe and increase system efficacy by using the pumping and transport action of the material in the pipe as part of the process activity.

A system and method for reducing the amount of infiltrate entering a sewer system is provided. The system generally comprises a locking sleeve, hydrophilic gasket, and a locking mechanism, wherein a lateral porthole of said locking sleeve is surrounded by said hydrophilic gasket. The system is preferably installed at a lateral line connection point, wherein a hydrophilic gasket located around the lateral porthole creates the water barrier that prevents infiltrate from entering a newly refurbished host pipe through the hole cut to reestablish flow from the lateral line to the host pipe at the lateral line connection point.

The invention relates to wastewater treatment systems with decentralized disposal of treated wastewater and methods of using the same. The invention further relates to methods of converting existing septic systems to a wastewater treatment plant system.

A drainage apparatus (100, 300-800) for siphoning liquid between first and second reservoirs (102, 104) is disclosed. In a first embodiment, the apparatus (100) includes a conduit arrangement having a first opening (112) disposed in the first reservoir (102), a second opening (114) disposed in the second reservoir (104) and a liquid injection inlet (106M2) arranged between the first and second openings (112,114), and a plurality of valves (108, 110) for controlling flow of the liquid along the conduit arrangement. A method (200) for priming the drainage apparatus (100) comprises directing liquid into the conduit arrangement at (202) via the liquid injection inlet (106M2) to fill up most of the conduit arrangement as controlled by the valves' configuration; directing liquid into the first reservoir (102) to enable more liquid to enter into the conduit arrangement via the first opening (112) to flood the conduit arrangement to form a continuous liquid flow path which extends from the first opening (112) up to at least the second opening (114), the continuous liquid flow path creating a siphon; and with the first opening (112) kept below the liquid's surface level in the first reservoir (102), stopping the flow of liquid into the first reservoir (102) to achieve a state of equilibrium of the siphon to prime the conduit arrangement. After the priming and in use, the siphon is triggered when more liquid is added into the first reservoir (102) which causes the added liquid to be siphoned to the second reservoir (104) via the primed conduit arrangement.

A power generation apparatus using a head of wastewater in a building includes an inclined water discharge pipe connected to an end of a wastewater pipe installed in the building through one end thereof, to divert a moving path of wastewater falling through the wastewater pipe, a cavity part coupled to the other end of the inclined water discharge pipe, to receive the wastewater discharged through the other end of the inclined water discharge pipe, and a rotating body installed inside of the cavity part, to be rotated by the wastewater discharged through the other end of the inclined water discharge pipe. Power is generated using a head of wastewater generated in a high-rise building or an apartment, and electricity generated using the wastewater is used as common electricity inside/outside the building. Therefore, smooth power supply can be achieved.
