System and method of retrofitting a lagoon entry system to a covered lagoon

A lagoon entry system for providing access to a covered lagoon for cleaning purposes without having to uncover the lagoon, the covered lagoon having a cover, a floor covered by a liner, and liquid contained therein having a surface level, and gas contained therein above the surface level of the liquid, the system comprising:

• a center wall;
• a conduit extending through an opening in the center wall;
• the conduit having an opening accessible from an exterior portion of the covered lagoon;
• the conduit having a gate covering the opening;
• wherein the gate provides selective access into the covered lagoon;
• an interior portion of the covered lagoon;
• the conduit in communication with the interior portion below the surface level of the liquid contained within the covered lagoon;
• wherein the liner of the covered lagoon is sealed to the conduit;
• wherein the cover of the covered lagoon is sealed to the center wall;
• wherein the gate is configured to receive a submersible robot cleaner configured to clean the floor of the covered lagoon.

A lagoon entry system for providing access to a covered lagoon for cleaning purposes without having to uncover the lagoon, the covered lagoon having a cover, a floor covered by a liner, and liquid contained therein having a surface level, and gas contained therein above the surface level of the liquid, the system comprising:

• a conduit configured to extend from an exterior portion of a berm around a periphery of the covered lagoon to an interior portion of the berm for providing communication between the exterior portion and interior portion;
• a gate covering an opening of the conduit on the exterior portion for providing selective access to the interior portion of the covered lagoon;
• wherein the conduit is in communication with the interior portion within the covered lagoon;
• wherein the liner of the covered lagoon is sealed to the conduit;
• wherein the cover of the covered lagoon is sealed to a top portion of the berm;
• wherein the gate is configured to receive a submersible robot cleaner configured to clean the floor of the covered lagoon.

A method of retrofitting a lagoon entry system to a covered lagoon, the covered lagoon having a cover, a floor covered by a liner, and liquid contained therein having a surface level, and gas contained therein above the surface level of the liquid, the method comprising:

• excavating material from an interior area of the covered lagoon;
• providing a center wall adjacent the interior area;
• wherein the center wall includes an opening extending through the center wall;
• wherein the opening in the center wall is located below the surface level of the liquid contained within the covered lagoon;
• the center wall having a gate covering the opening;
• wherein the gate provides selective access into the covered lagoon;
• connecting an interior portion to the center wall;
• wherein the interior portion of the lagoon entry system is placed on the interior area;
• sealing the liner of the covered lagoon to the interior portion;
• sealing the cover to the center wall;
• and
• wherein the gate is configured to receive a submersible robot cleaner configured to clean the floor of the covered lagoon.

A method of retrofitting a lagoon entry system to a covered lagoon, the covered lagoon having a cover, a floor covered by a liner, and liquid contained therein having a surface level, and gas contained therein above the surface level of the liquid, the method comprising:

• cutting a hole in the cover of the covered lagoon;
• cutting a hole in the liner of the covered lagoon;
• excavating material from a berm surrounding a perimeter of the covered lagoon;
• providing a conduit within the excavated material of the berm;
• wherein the conduit extends from an interior of the covered lagoon to an exterior of the covered lagoon;
• wherein the conduit includes an opening at the exterior of the covered lagoon;
• the conduit having a gate covering the opening;
• wherein the gate provides selective access into the covered lagoon;
• sealing the liner of the covered lagoon to a portion of the conduit extending into the interior of the covered lagoon;
• sealing the cover to a top portion of the berm;
• and
• wherein the gate is configured to receive a submersible robot cleaner configured to clean the floor of the covered lagoon.
