Interceptor Drains
EZflow
can be used to intercept groundwater movement toward an area where
water table control is essential. Elevation must be lower than
protected area. Aggregate should extend upward to intercept all
moving water.
In areas of high ground water, seepage
from slopes created during development may cause erosion of slopes.
EZflow
interceptor drains can prevent this erosion by diverting high ground
water to a safe outlet. Subsurface drainage such as
EZflow
interceptor drains need to be installed with an even downward slope
toward an outlet. Minimum slope should be about 1" per 10'.
This may require the use of a builder's level and level rod. A
barrier over, or no more than three-quarters around, the
EZflow
units may be required to prevent sand-like soils from entering the
EPS aggregate. The type of barrier can be untreated building paper,
filter fabric, newspaper, or straw and should be selected based on
site conditions. Local practices in similar applications and soils
may be a guide as to the type of barrier that should be used. Check
your local codes before proceeding.
