Perennial aromatic plants are cultivated as cash-crops for fresh or dry herb production, or as a source of essential oils. They require substantial amounts of water in order to satisfy their potential for intensive production. In arid and semiarid regions, where shortage of fresh-water restricts agricultural production, irrigation with marginal water is an unavoidable practice. The largest source of marginal water for agriculture is secondary-treated municipal sewage water. This water differs chemically and physically from the potable water from which they originated, and may therefore affect the irrigated plants. Development of aromatic production systems based on irrigation with treated effluent, will allow development of essential oil production systems in arid and semi-arid zones. In the present study we have screened a range of aromatic crops for their suitability to grow under irrigation with secondary treated effluent, and as a source of essential oil. During a three years project, the growth and morphological development of six aromatic plants, and their yield quantity and quality under irrigation with effluent, was compared to cultivation with potable water. The results which demonstrate that secondary treated municipal effluent are suitable for growth and quality production in all species tested, forms the foundation for effluent-based industrial essential oil production. © 2012 Nova Science Publishers, Inc.
