1 Providing solutions forall On-Site Septic designand installation Septic Systems2On- site Septic SystemsIn the today, most peopleenjoy the comforts and peace ofmind that come from living in ahouse served by a publicsanitary sewer , it is estimated that25% of the population livewithout access to a publicsanitary sewer system . Theydepend upon On-Site septicsystems for the treatment anddisposal of householdsewage. Many of thesesystems consist of aseptic tank and a soilabsorption area wherethe effluent is leachedinto the commoncomponent of allsoil absorptionlines and/or fieldsis a type ofconduit thatdistributes theeffluentthroughout thesoil. The soil hasthe function of absorbing andtreating effluent. If the soilabsorption system is designedproperly, there is adequatesoil absorption area for the flowof effluent created by thehousehold, then the leach fieldwill function indefinitely with D 5829 Standard Practice for Surface SiteCharacterization for On-Site Septic D 5921 Standard Practice for Subsurface SiteCharacterization of Test Pits for On-Site Septic F 481 Standard Practice for Installation ofThermoplastic Pipe and Corrugated Pipe in Septic TankLeach referred-to specifications indesigning Septic Leach Fields: Septic TANKSOILABSORPTIONSYSTEMDISTRIBUTIONBOXP ERIMETERDRAIN ADS is the largest manufacturer ofpolyethylene pipe in the world.

2 Since1967, ADS has supplied contractors with4" high-density polyethylene septicproducts which are inert and corrosionresistant to normal household offers several different types ofconduits that can be used in soilabsorption areas. 3 Gravel-less Systems includeSB2 pipe, Multi-pipe Systems ,GEO-flow pipe and HDPE leaching chambers. These arethe most commonly usedconduits in gravel-less the the EPA, thegravel in a conventional pipeand gravel system performsthree basic functions: 1) itsvoid spaces provide storagecapacity for the effluent; 2) itprotects the infiltrative surfacearea of the soil; 3) it supportsthe excavation. The graveldoes not digest, treat oreliminate the inherent in the use of gravel in a soilabsorption system include compaction of the infiltrativesurface during installation; fines, which reduce theeffectiveness of the infiltrative surface, and masking ,where the effluent cannot enter the soil at points wherethe rock is in contact with "Soil8" or 10"SB2 PipeThe second basic type of soilabsorption system is thegravel-less system .

Two professionalsanitarians in Texas, John Scroffand John Barnes, developed theSB2 gravel-less pipe to addressthis keys to the excellentperformance of SB2 pipe are thesize of the pipe and the location of the drain holes.

4 The outsidediameters of the 8" and 10" SB2pipe provide the equivalent of 2and 3 square feet, respectively, of soilabsorption area per linear foot. Thelocation of the drain holes, 60 off thebottom center line, providesadditional sludge storage capacity,which increases retention holes 60 off bottom center line creates additional sludge storage Guard Protective WrapDrain Guard is a spun-bonded nylon wrap that is overlapped and sonically welded. It provides anexcellent soil interface for passage of effluent into thesoil. The valleys of the corrugations function asadditional storage capacity, since the fabric bridgesthe corrugations and allows for the free movement ofthe effluent out and around the " or 10"18" " SoilBackfillDrain Guard protective wrap(soil interface)Sludge retained inpipe to reduce soilinterface cloggingTrench bottomDrain holes,located 60 off bottomcenter line,provideoutlet foreffluentBedding 0" to 2"Recommended trench width for the SB2 gravel-less drainfield is 18"-24".

Thepatented Multi-Pipe unitsfunction as a trickle filter,dispersing effluent into the voidsin and around the specially-banded ADS pipe. This pipe isengineered with holes and slots,allowing it to collect anddisperse the effluent as itpasses over the corrugations inthe pipe.

10 This is achievedby combining the traditional,open bottom with a series oflouvers along the sides. Thelouvers are designed to alloweffluent to pass into the backfillwhile preventing the backfillfrom migrating into thechamber.
