A wastewater treatment and disposal system includes a pressure system for forcing wastewater effluent from a treatment tank to a subsurface dispersal/reuse area. Filtered effluent is discharged into the dispersal area through a system of drip irrigation-type driplines contained inside separate elongated, generally tubular sleeve-like enclosures running along the length of each dripline. The sleeve-like enclosures are made of flexible geotextile subsurface drainage fabric for spreading out the effluent discharged to the dispersal area from the driplines. At least a portion of the drainage fabric may contain an herbicide for forming a "biobarrier" that inhibits undesired root growth into the fabric. The sleeved geotextile fabric can set up a biologically active zone in the ground around the dripline. Air can be injected into the biologically active zone through the dripline emitters for dewatering and/or for treating an anaerobic condition in the zone, for changing the zone to a more aerobic condition.
