Hemoglobin is the iron-bearing and oxygen-carrying component of red blood cells. The normal value for hemoglobin varies by age and gender. Anemia is generally considered when hemoglobin concentrations fall below 11 g/dL for pregnant women, 12 g/dL for non-pregnant women, and 13 g/dL for men.emoglobin is the iron-bearing and oxygen-carrying component of red blood cells.

A soil pipe is a PVC or cast iron pipe used in plumbing installations to remove soiled or contaminated water from toilets. Soil pipes differ from normal waste water removal pipes in that they are generally of a larger diameter and are designed specifically to remove solid waste from toilets.
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. 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.
