Horizontally draining artificial turf system
First Claim
1. An apparatus to drain turf, the apparatus comprising:
- a sloped blanket beneath a horizontal permeable turf layer with vertical openings to direct water vertically;
a permeable base beneath the blanket to allow the water to flow vertically;
a pipe inside the base to collect the water to direct the water to a main drainage system.

Abstract
A horizontally draining artificial turf system comprises an impervious base at proper slope, an impermeable layer or drainage blanket over the base at a corresponding slope for guiding water horizontally, an artificial turf at top of the impermeable layer, and a perforated pipe near the lower edge of the base for receiving water for evacuation. Rainwater over the artificial turf first drains vertically onto the impermeable layer and then flows along the impermeable layer to reach the perforated pipe, without infiltrating into the base. Alternatively, a partially pervious drainage blanket is provided in lieu of the impermeable layer where the base is partially pervious. Backup rainwater runs off the drainage blanket horizontally after it saturates the soils of the base.

6. An apparatus to drain turf, the apparatus comprising:
-
a sloped blanket beneath a horizontal permeable turf layer with vertical openings to direct water vertically;
a permeable stone and rock base beneath the blanket to allow the water to flow vertically;
a pipe inside the base to collect the water to direct the water to a main drainage system. a plurality of horizontal openings in a middle portion of the blanket, wherein the plurality of vertical openings direct water flowing from the vertical openings into the plurality of horizontal opening which directs the water to the main drainage system, wherein the plurality of vertical openings reach the bottom of the blanket, thereby allowing the water to travel into the plurality of horizontal openings and the plurality of vertical openings.
