The Laterals
Categories:
DRAINAGE
Small lines of tile are used to bring the water to the
main when the wet land extends beyond the influence of the main. The
distance between these laterals depends upon their depth and the nature
of the land. A tight clay soil will not let water pass laterally more
than a rod or 20 feet, compelling the placing of the drains not over 40
feet apart, while an open soil may permit a distance of 60 or more feet
between laterals.
