a cylindrical portion having a bottom end and a top end opposite the bottom end, the bottom end having an outer diameter sized to fit within the accessway opening of the first tank;
a flange portion connected to the top end of the cylindrical portion; and
one or more pipe stubs in fluid communication with the cylindrical portion and externally protruding from the cylindrical portion in a first direction, the one or more pipe stubs having a distal end that is capped;
a second tank having a top end with an accessway neck extending from the top end and defining an accessway opening, the second tank operable to be in fluid communication with the first tank via piping; and
a second connection adapter coupled to the accessway opening of the second tank, the second connection adapter comprising:
a cylindrical portion having a bottom end and a top end opposite the bottom end, the bottom end having an outer diameter sized to fit within the accessway opening of the second tank;
a flange portion connected to the top end of the cylindrical portion of the second connection adapter; and
one or more pipe stubs in fluid communication with the cylindrical portion of the second connection adapter and externally protruding from the cylindrical portion of the second connection adapter, the one or more pipe stubs of the second connection adapter having a distal end that is capped,
wherein the second connection adapter is oriented relative to the second tank so that the one or more pipe stubs of the second connection adapter extends in a second direction that is different than the first direction.
10 . The tank system of claim 9 , further comprising a first riser section connected to the flange portion of the first connection adapter.
11 . The tank system of claim 10 , further comprising a second riser section positioned between the accessway neck of the second tank and the second connection adapter.
12 . The tank system of claim 9 , wherein the first connection adapter includes an open-ended pipe stub in fluid communication with the cylindrical portion of the first connection adapter and externally protruding from the cylindrical portion of the first connection adapter, further comprising piping extending through the open-ended pipe stub into the first tank.
13 . The tank system of claim 12 , further comprising one or more flexible couplers with a first end that receives the open-ended pipe stub and a second end that receives the piping.
14 . A method of installing one or more water reclamation tanks, the method comprising:
positioning a first connection adapter in fluid communication with a first tank, wherein:
the first tank has a top end with an accessway neck extending from the top end and defining an accessway opening, and
the first connection adapter comprises:
a cylindrical portion having a bottom end and a top end opposite the bottom end;
a flange portion connected to the top end of the cylindrical portion; and
one or more pipe stubs in fluid communication with the cylindrical portion and externally protruding from the cylindrical portion, the one or more pipe stubs having a distal end that is capped;
positioning the first connection adapter so that the one or more pipe stubs thereof extends in a first direction;
removing a portion of the distal end of the one or more pipe stubs;
inserting piping into the one or more pipe stubs;
positioning a second connection adapter in fluid communication with a second tank, wherein:
the second tank has a top end with an accessway neck extending from the top end and defining an accessway opening, and
the second connection adapter comprises:
a cylindrical portion having a bottom end and a top end opposite the bottom end;
