Abstract—H. M. The King's initiative Laem Phak Bia environmental research and development (LERD) project has been selected Laem Phak Bia sub-district, Ban Laem district, Petchaburi province which is about 18.5 km away from points sources at Petchaburi municipal. Transferring community wastewater was really needed to take HPDE pipe because of high pressure requirement for 50-cm head between Klongyang pumping station to the project site and also unpleasant smell in case of using open channel sewer system. The original point sources are far away about 5 km to 8 km to in-town collection pond which is localized at fresh-food markets, households, shopping center, dessert factories, Thai rice noodle factories, and government offices in which they produce wastewater approximately 7,000 m3/d. The pumping capacity was estimated 3,000 to 3,600 m3/d through 18.5-km HPDE pipe to the LERD's project site without any interruption. The research results found that the Royal LERD wastewater treatment system to decrease the high content of BOD down to under standard value after overflowing weir crest of the last pond (pond5). In addition, the anaerobic organic digestion processing distance was determined by graphical method with free hand curving that pointing out on 2,000 meters that moving from the start-up point at Klongyang collection pond through the 18.5- km HPDE pipe tail. Only the values of BOD and anaerobes had evidently shown in variable patterns, but the others found more or less changeable patterns, i.e. COD, NH4, NO2, alkalinity, hardness, SS. TDS, EC, orthophosphate, total phosphate, temperature, aerobes, facultative bacteria, total coliform, fecal bacteria, and DO (0.000 to 0.003 mg/L).

Index Terms—Anaerobic organic digestion, wastewater treatment, nature-by-nature.
