The Wasteflow dripline irrigation system from Geoflow is placed directly into the soil, at the plant’s root zone, where effluent is released slowly and uniformly to be digested and absorbed safely. It can be used on difficult sites, including shallow soil profiles, steep slopes, limited setbacks or in areas with poor soils. Rootguard molded into each emitter protects against root intrusion, while the Geoshield component protects against biological buildup. 800/828-3388; www.geoflow.com.
