Si, por razones de viabilidad económica y financiera, el tratamiento terciario ha de realizarse en una fase posterior, la infraestructura que reciba ayuda del ISPA deberá concebirse de manera que se eviten unos costes adicionales excesivos cuando se lleve a cabo el tratamiento, previendo de antemano el terreno, las conexiones hidráulicas con la futura ampliación de la planta, etc.
