Re: Back yard never dries out..where to start?
If the septic leach field is in the area that is saturated, you may want to install an "interceptor drain" on the uphill side of the leach field.
Basically, you dig a trench, place perforated pipe in the bottom of the trench, and fill it with gravel. You can cover it with landscaping fabric then a layer of soil.
Groundwater will flow into this pipe, which them must be routed around the leach field through solid pipe to an appropriate location downhill of the leach field.
Septic leach fields depend on evaporation. Whatever wastewater in the leach field that doesn't percolate downward into the water table must evaporate out, which is most of it. If the soil has become compacted, it may not be able to evaporate sufficiently so it will stay soggy.
Likewise, if you have a lot of natural runoff (groundwater) from elsewhere flowing into your leach field, evaporation will be inhibited. A properly installed interceptor drain will prevent this runoff from entering the leach field.
