Abstract
A filtration and subsurface distribution system having a vaulted splitting device (e.g., dosing vault) in a recirculating pump tank. The recirculating pump tank houses a sand filter pump and the dosing vault houses a dosing pump. The dosing vault and the dosing pump may be housed outside and remote from the recirculating pump tank which ensures that effluent will not be mixed within the dosing vault. The sand filter pump doses a sand filter with the septic effluent via a feed line. The effluent is then filtered by the sand filter and returned to the dosing vault via a filtrate return. When the filtrate reaches a certain predetermined level within the dosing vault, the drip pump is enabled and turned “on”. In this manner, the filtrate is dosed or dripped into a drain absorption field without mixing with the septic effluent.
