A biofiltering system for treating wastewater effluent (e.g. from a septic tank) through a bed of peat 16 overlying an effluent absorption area 12 and into the earth beneath 14. The bed of peat has a predetermined biofiltering capacity. A fluid flow regulator 18 upstream from the peat is adapted to allow the effluent to flow at a rate greater than the peat bed biofiltering capacity. However, a distribution system arranged over the peat is configured such that wastewater received from the fluid flow regulator flows through the peat bed at a rate no greater than the peat bed biofiltering capacity. The distribution system 20 includes a plurality of spaced-apart, elongated distribution conduits 72 having discharge orifices 74 spaced longitudinally therealong. The biofiltering system allows large quantities of wastewater to be efficiently treated irrespective of the flow rate thereof.
