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.
But it exists even more demonstrably in the northern suburbs. According to 2013 Census population estimates, two of the nationâs 15 fastest-growing cities of 50,000 or more are the northern Dallas suburbs of Frisco and McKinney. Other examples to the north include Plano, Denton, Garland, Carrollton, Richardson, and Allen, all of which have grown by at least 20,000 people since 2000, and many of them by far more.
