<br />H-lO <br /> <br />e <br /> <br /> <br />SEEPAGE PIT <br />(DRY WEL ) <br /> <br />~ <br /> <br />~~'''' <br /> <br />Figure H-8 <br /> <br />e <br /> <br />waste household sewage or liquid waste is discharged and from which <br />liquid seeps into the surrounding soil through bottom openings in side <br />of the pit. A system that meets these definitions is automatically <br />detemlined to be a nonconforming system, because this type of system <br />does not maintain the-level of treatment required to discharge effluent <br />into the surrounding groundwater. <br /> <br />Seepage Pit= <br />Nonconforming <br /> <br />Thes~ systems should be upgraded when loc~lted. The solutions for <br />these systems may be varied, but in some cases, offsite collector <br />solutions may be necessary. <br /> <br />Direct Discharge to Lake Surface or Tile <br /> <br />Step 3 <br /> <br />Any system that directly discharges effluent to the surface or drainage <br />tile is considered nonconforming. These systems maintain no <br />treatment and must be upgraded. They cause the most severe damage <br />to lakes or other surface waters, not only in the transfer of nutrients <br />but in the possible spread of disease as well. These systems would <br />probably be the first recognized by infrared air photography. <br /> <br />Water Table Less Than 3 Feet from the Bottom of the Existing <br />Treatment System <br /> <br />Step 4 <br /> <br />e <br /> <br />For this decision to be completed, the water table must be first <br />determined. In most shoreland situations, the high water mark of the <br />lake and the water table are essentially the same. In some cases, <br />however, the water table may follow the topography of the land and <br />will be indicated by soil modeling. (See Figure H-9.) <br />
