How often should collection lines be placed in feet?

The correct answer is that collection lines should be placed 10 feet apart. This distance is based on established guidelines to ensure proper sewage flow and to minimize the risk of backflow or blockages. The 10-foot spacing allows for adequate coverage of the area to ensure that effluent is effectively collected, while also considering factors like soil absorption and system performance.

When planning the layout of a sewage system, it's important to create an efficient network that optimizes both functionality and maintenance access. If collection lines were placed too closely together, it could lead to redundancy and inefficiency, while placing them too far apart could cause gaps in coverage, leading to potential system failures. Therefore, a 10-foot spacing strikes the right balance for effective sewage management, ensuring that all areas are sufficiently served without overwhelming the system's capacity.
