Said secondary tube has a series of second holes leading from the interior of said secondary tube to the exterior. A flexible, filamentary line, ridge or groove is positioned within said secondary tube and forms a restricted path for water flowing from a first hole to a second hole. Optionally, at least one tertiary tube of flexible, water-impermeable material is joined to said secondary tube at a second common wall, with said second holes through said second common wall. Said tertiary tube has a series of third holes leading from the interior of said tertiary tube to the exterior and a flexible, filamentary line, ridge or groove is positioned within said tertiary tube.
