On-Site wastewater systems are normally associated with the treatment of liquid waste and their proper disposal. Originating from sources such as municipal sewage treatment plants, residential septic tanks and commercial and residential small package plants, large volumes of wastewater are generated treated and recycled daily. But, did you know that this type of waste is also generated and treated along the interstate highway? The rest areas we all must visit at one time or another have small wastewater treatment plants or large septic tanks and leach fields. This type of wastewater is treated with an on-site plant and is normally recycled within the roadside rest area. Literally hundreds of thousands of septic tanks and treatment plants are installed everyday across the United States. Residential waste treatment in the United States is a big business and is becoming more efficient every day with new products. Web sites that provide additional information on small flows have been linked to this page for your information and convenience. One such site is the National Small Flows Clearinghouse. National Small Flows Clearinghouse Headquartered at the University of West Virginia, and active in processes involving small flows is an excellent source of information for anyone interested in this vital field. Another informative site http://www.wateronline.com is active in all water related industries, with small or large flows. We often visit these sites to determine the collective direction of the wastewater industry at large. This helps us design and manufacture new products to meet future demands.

Septic tanks and small package plants have traditionally been serviced by leaching lines in trenches or leach-beds. These septic tank and drain field combinations are a primary industry for PTI Corr-A Flex ^TM LC Perforated pipe. PTI manufactures a complete line of pipe and fittings to meet the needs of this industry. Since our beginning in 1969 we recognized the need to replace clay tiles with a recyclable product long before it became popular. The material HDPE and the company PTI are a perfect combination for this industry. We did not stop with the production of conventional leaching line products. In fact, we have improved on the age old technology surrounding septic lines by inventing a totally new leaching system that does not need or use mineral aggregate. This system is patented and has proven itself in some of the most demanding site-specific situations. The new system is more porous, has more volume and distributes up to thirteen times better in the same soils and situations as a conventional rock filled system. Now we can save the rock for more important and appropriate uses such as the mountains and mines they came from.
