A drain system for transporting waste from a vehicle to a discharge location located spaced from the vehicle may include first, second and third modular components. The first modular component may be adapted to coupling to the vehicle and may define a first male connection. The second modular component may include a waste transfer portion extending between a first end and a second end. The first end may define a first female connection and the second end may define a second male connection. The third modular component may include an angled central portion, a first end and a second end. The first end may define a second female connection. The second end may define a waste discharge end. The drain system may further include a fourth modular component defining a first end having an opening for receiving the waste discharge end of the third modular component and a second end for interfacing with a tubular intake of the discharge location.
