A typical septic drain field (see Figure 1), also known as a leach field, is a series of perforated pipes that are set in trenches and buried with aggregates (Â½- to 2Â½-inch gravel or Â½- to 4-inch rubber chips) and soil.These drain lines are at a minimum depth of 6 inches and are typically 18 to 36 inches wide.The individual drain lines will usually be 8Â½ to 10 feet apart (see Figure 2). It is important to note here that each drain field system will vary from the next.hese drain lines are at a minimum depth of 6 inches and are typically 18 to 36 inches wide.

Frisco is the fastest-growing city in America. No, not THAT Frisco with the incessant fog and Golden Gate Bridge (not to mention, locals will scoff if you call it Frisco). Weâre talking Frisco, Texas. The Dallas suburb scored No. 1 on WalletHubâs list of fastest-growing cities in America due to its rapid job and population growth. The city is home to the National Videogame Museum, Dr Pepper Arena (home of the Frisco RoughRiders), and the Dallas Cowboys headquarters.
The city has topped our list of Fastest-Growing Cities for five of the past six years (last year it slipped to second place). But Utahâs fastest-growing cities are exhibiting impressive acceleration: Salt Lake City jumped seven spots on our list and Ogden returns to it after falling off in 2015.
