• Abstract:
  In November of 1996 an interstate rest area was opened on I-49, approximately 20 miles north of Opelousas, Louisiana. Wastewater generated in the main building as well as that from an RV dump station is treated using subsurface flow, rock plant filters preceded by two septic tanks in series. Treated effluent is disinfected and discharged to Lake Dubuisson. Discharge permit limits are 45 mg/liter biochemical oxygen demand (BOD) and 45 mg/liter total suspended solids (TSS). The purposes of this study were to (1) compare the hydraulic regime in "long narrow" filters with that in "short wide" filters, (2) compare the treatment effectiveness of this process so far as meeting existing and expected permit limitations with other waste treatment processes in use at Louisiana rest areas, and (3) assess the nature and amount of operation and maintenance required at this facility compared to that required at package mechanical plants. Results to date indicate that the system is insensitive to variations in flow and will meet or exceed its permit requirements approximately 90% of the time. The system requires no proactive operation and minimal maintenance. Skill levels required are within the capabilities of current DOTD personnel. It is recommended that processes for the removal or conversion of ammonia be investigated in anticipation of future discharge limitations.
