A water timer system includes a base assembly and an input and display module. The a base assembly includes (i) a conduit structure defining an inlet, an outlet, and a passage extending between the inlet and the outlet, (ii) a first housing defining a first chamber, (iii) a motor located within the first chamber and having an output member, (iv) a gear set located within the first chamber, wherein movement of the output member causes movement of the gear set, (v) a valve member movable between a first valve position in which the valve member is positioned to prevent water flow through the passage and a second valve position in which the valve member is positioned to enable water flow through the passage, wherein movement of the gear set causes the valve member to move between the first valve position and the second valve position, (vi) receptacle structure defining a first aperture and a second aperture. The input and display module includes (i) a second housing defining a second chamber and a third chamber, (ii) timer circuitry located within the second chamber, (iii) an input and display device configured to provide input signals to the timer circuitry in response to user actuation and to display indicia relating to an operating state of the water timer system, (iv) electrical terminals located in the third chamber and electrically connected to the timer circuitry, (v) a first projection extending from the second housing and configured to be received within the first aperture of the receptacle structure, and (vi) a second projection extending from the second housing and configured to be received within the second aperture of the receptacle structure. The third chamber is at least partially positioned between the first projection and the second projection.
