Causes of imbalance in older people. Balance in walking and standing is dependent on many factors. Good balance requires reliable sensory input from the individualâs vision, vestibular system (the balance system of the inner ear), and proprioceptors (sensors of position and movement in the feet and legs).
Reclaimed water, also known as recycled water, is water recovered from domestic, municipal, and industrial wastewater treatment plants that has been treated to standards that allow safe reuse. Properly reclaimed water is typically safe for most uses except human consumption. Wastewater is not reclaimed water.
Graveled Systems. The older-style graveled systems contain a layer of gravel in the drain field. While some treatment of waste occurs in the septic tanks, most of the treatment occurs as wastewater discharged from the tank enters the drain field and is filtered through the gravel and the soil below. Over time, bacteria and other organisms in the soil consume any organic material in the wastewater.
