wherein said second end of said first outlet pipe connector section is attached to said first end of said second outlet pipe connector section by a first living hinge to allow said first outlet pipe connector section to fold back toward said second outlet pipe connector section.

9 . The catch basin trap as claimed in claim 8 , wherein said collapsible outlet pipe connector further comprises a third outlet pipe connector section having a first end and a second end;

wherein said first end of said third outlet pipe connector section is attached to said second end of said second outlet pipe connector section by a second living hinge, to allow said folded first and second outlet pipe connector sections to fold back toward said third outlet pipe connector section.

10 . The catch basin trap as claimed in claim 9 , wherein said collapsible outlet pipe connector comprises one or more additional outlet pipe connector sections attached to said second end of said third outlet pipe connector section in series by one or more additional living hinges to allow said folded outlet pipe connector sections to continue folding back toward said next additional outlet pipe connector section in said series.

11 . The catch basin trap as claimed in claim 1 , wherein said continuous upstanding flange is sized and shaped to form a substantially watertight seal between said body of said catch basin trap and said opening in said side wall of said catch basin.

12 . The catch basin trap as claimed in claim 1 , further comprising at least one outlet pipe stop member attached to said inlet opening.

13 . The catch basin trap as claimed in claim 1 wherein:

the catch basin trap is held in said opening in said side wall; and

said collapsible outlet pipe connector is in said collapsed configuration.

14 . A concrete catch basin, comprising:

a sidewall having an opening therein;

a catch basin trap attachable to the opening in the side wall of the catch basin, said catch basin trap including:

a body being monolithically formed and having a front side wall for facing outwardly to outside of said catch basin, and a back side wall for facing inwardly to inside of said catch basin, said body defining a chamber located between said front side wall and said back side wall;

an inlet opening in said back side wall of said body for receiving drainage water from said inside of said catch basin;

an outlet opening in said front side wall of said body;

a collapsible outlet pipe connector attached to said outlet opening, said collapsible outlet pipe connector being configured to be manipulated from a collapsed configuration to an extended configuration defining a discharge end adapted for coupling to an outlet pipe positioned outside said catch basin;

a water flow path for said drainage water from said inlet opening to said collapsible outlet pipe connector, via said chamber, and said outlet opening; and

an upstanding flange attaching said catch basin trap to said opening in said side wall of said catch basin, said upstanding flange embedded in said side wall of said catch basin; wherein said collapsed configuration stows said collapsible outlet pipe connector within said body, and said extended configuration permits watertight coupling of said discharge end of said collapsible outlet pipe connector to said outlet pipe.

15 . A catch basin trap for attachment to an opening in a side wall of a catch basin, said catch basin trap comprising:

a body having a front side wall for facing outwardly to outside of said catch basin, and a back side wall for facing inwardly to inside of said catch basin, said body being monolithically formed and defining a chamber located between said front side wall and said back side wall;

an inlet opening in said back side wall of said body for receiving drainage water from said inside of said catch basin;

an outlet opening in said front side wall of said body;

a collapsible outlet pipe connector attached to said outlet opening, said collapsible outlet pipe connector being configured to be manipulated from a collapsed configuration to an extended configuration defining a discharge end adapted for coupling to an outlet pipe positioned outside said catch basin;

a water flow path for said drainage water from said inlet opening to said collapsible outlet pipe connector, via said chamber, and said outlet opening; and

an upstanding flange for attaching said catch basin trap to said opening in said side wall of said catch basin, said upstanding flange extending outwardly from said body continuously around a periphery of said body, between said front side wall and said back side wall, said upstanding flange being configured to have sufficient strength and resiliency to:

support the body and maintain the position of the body during concrete casting of said catch basin in a mold such that the upstanding flange is embedded in the cast concrete and said body is held in said opening after said cast concrete catch basin has cured; and

provide a substantially watertight seal between the body and the side wall of the catch basin when embedded in the side wall;

wherein said collapsed configuration stows said collapsible outlet pipe connector within said body, and said extended configuration permits watertight coupling of said discharge end of said collapsible outlet pipe connector to said outlet pipe.

16 . The catch basin trap as claimed in claim 15 , wherein the body is monolithically formed.

17 . The catch basin trap as claimed in claim 16 , wherein said back side wall of said body comprises an access opening to allow for cleaning of said chamber, said catch basin trap further comprising a cover releasably attached to said access opening for covering said access opening when said catch basin trap is in use.
