After a floor plan has been proposed and approved, the profile of the control building can be designed. A standard eight foot high building will work for most applications, but there are some components housed within the control building that can change this. For instance, an odor control system can have a chemical feed tank that is 1100 gallons and 8-1/2 feet tall. Most likely this tank is set in the corner and will barely fit, if at all, under the roofing. The building profile also includes all the doors and ventilation. A roll-up door may be necessary for the building, and placement must be considered in conjunction with the component layout. Ventilation is also a key factor in designing a control building. A generator creates exhaust and this has to be properly expelled from the building to ensure the safety of any people working inside. Noise is another determining factor for the control building. Generators can be very loud and this is a problem if the lift station is located within close proximity to houses. Noise reduction steps must be taken to minimize the impact on the area. Finally, aesthetics could be vital in the design of the control building. If the building sits right in the middle of a California, ocean-side, upscale community, it better not draw attention. In this situation, it is crucial to design and build a visually appealing control building that blends in.
