A plastic well (10) includes a plastic well casing (12) with a hole (16) that is disposed transversely to a casing axis (14). A plastic adapter plug assembly (38) is disposed inside the casing (12) and is forced toward the transversely-disposed hole (16) in the casing (12) by a plastic locking cam (58) that is a part of the adapter plug assembly (38). The adapter plug assembly (38) is supported by a plastic support plate (26) that engages the top (28) of the casing (12), and by a plastic support tube (32) that is bonded to both the support plate (26) and the adapter plug assembly (38). A plastic saddle (18) is disposed outside the casing (12) and is bonded over the hole (16) in the casing (12).
