Department of Public Works Sewer and Drain Maintenance division, showing an employee oiling the bearing on the station ventilation motor, ca.1927

Photograph of an interior view of the Department of Public Works Sewer and Drain Maintenance division, showing an employee oiling the bearing on the station ventilation motor, ca.1927 The room is rounded with lightly-colored walls stained with dark drips. Two large, cylindrical machines stand on the right while a man in a hat operates a lever on the left. A thick pipe bends into the ground on the far left while a picture hangs from the wall on the right. Additional information: The photo shows the interior of a sewage pump station, motor room level. It clearly shows the two electric pump motors located to the right of the employee. The employee is oiling the bearing on the station ventilation motor. The photograph also features the pump station work bench next to the electrical boxes with the "Stop Mistakes in Painting" advertisement which can be seen in the background, at left. The work bench was a standard feature for this type of City of Los Angeles sewage pump station and is specified in the pump station plans, along with a bulletin board (not shown in photo). The pump station has two levels, with this being the top floor. The level below houses the pumps and wet well. The staff gauge is visible on the wall behind the employee that measures the water level in the wet well. Other details shown in the photo include the glass oilers at the base of each pump motor and the tool board (with pipe wrench and pliers) to the right of the pump motors. Based on the circular brick construction of the station, the double hung windows and general layout, the photograph could be of the Mar Vista sewage pump station that was built circa 1927.这张摄于约1927年的照片，展现了公共工程局（Department of Public Works）下水道与排水维护部门的内部场景：一名工作人员正在为泵站通风电机的轴承加注润滑油。该房间为圆形结构，浅色墙面带有深色污渍流淌痕迹。右侧摆放两台大型圆柱形设备，左侧一名戴帽男子正在操作操纵杆。最左侧有一根粗管道弯折伸入地下，右侧墙面悬挂一幅装饰画。 补充说明：该照片拍摄于一座污水泵站（sewage pump station）的电机机房层，清晰展现了工作人员右侧的两台电动水泵电机，以及工作人员为泵站通风电机轴承加注润滑油的场景。照片左侧背景处的配电箱旁设有泵站工作台，台面上可见"Stop Mistakes in Painting"的宣传广告。此类工作台是洛杉矶市（City of Los Angeles）同类型污水泵站的标准配置，泵站设计图纸中还规定需配备公告栏（bulletin board），但该照片中未呈现此设施。该污水泵站共两层，本次拍摄的为顶层，下层设置水泵与集水井（wet well）。工作人员身后的墙面上设有水位标尺（staff gauge），用于测量集水井内的水位。照片中其他细节还包括：每台水泵电机底部的玻璃注油器，以及水泵电机右侧的工具板——其上配有管钳与钳子。结合泵站的圆形砖砌结构、双悬窗（double hung windows）与整体布局推测，该照片拍摄的应为建于约1927年的马维斯塔污水泵站（Mar Vista sewage pump station）。
