C2f:u€.. td'T:I tri and O e.rat4F'4'; R 'ITFOMi ti— the primary and secondary wastewater dispersal systems were constructed in winter 3004, during a particularly rainy period of time. According to Chocoholics management, the Infiltrator chambers were reportedly installed in standing water and mud. Due to a miscommunication on valve operation, the manual distribution valve was initially set to direct all wastewater to the secondary dispersal system. After the first year of operation, the manual distribution valve was switched to send wastewater to the primary dispersal system. Within three days wastewater was reportedly surfacing at the southwest corner of the dispersal area. After a subsequent resting of the prhnary dispersal system, Chocoholics management ran the effluent pumps continuously to pump a known volume of effluent (1,400 gallons) into the primas dispersal system and then monitored the resulting wastewater levels. Based on the observed water levels, infiltration was much slower than the design criteria. The effluent storage capacity within the Infiluator chambers was also less than expected. The secondary wastewater dispersal system has been accepting the entire flow from the septic tanks. After about a year of operation, odors that had been detected on occasion were identified as coming from the gravity-distribution box at the beginning of the secondan system. Wastewater backing up into the secondary distribution boli was found to be the source of the odors. The box was subsequently bypassed using pressure piping to eliminate the odor. The cause of the wastewater backup in the secondary system was not determined. - 3 . SITE INSPECTION An initial site visit and inspection was performed on )uly 6, 3006. The scum thickness and character risible through the septic tank access ports was about as would be expected. The biombes had not been plugging noticeably between cleaning events (approximately every two months). It should be noted that the biotubes cannot be completely removed for recommended maictenance because of the piping installation. Only thQ very-ends of two Infiltrators were visible through access ports. The soil surface in the soutlivest Infiltrator appeared to be relatively-close to the Infiltrator ceiling. This corresponded with the obsenirion by Factor-management that the sides of some Infiltrators had subsided into the soil, leaving reduced chamber volumes. The surface of the primary dispersal Field seas grass. The surface had some subtle elevation Isclabilin_-,which could have been due to differential settling of the InhlLumirs. Elevation differential between laterals could also be contributing to translOeadun of effluent fmrn higher laterals to lower herals. once in[rltratur charubers begin filling. mill 2 �rrd bu,Afl n-� ,ro"_i _
