Is the reclamation of the water supplied by a municipality? If so, not much is needed except for the "violet colors " on the valves, heads, valve boxes, and pipe (the national do not drink color). But, that may differ depending on your county and city requirements. If, however, it is not reclaimed by a municipality of some sort, make sure you use a self cleaning valve. Such valves as the Rain-Bird PESB series or the Hunter Sentry (if memory serves me correctly). These will automatically clean the metering port on the diaphragm on every start and shut down. Most reclaimed water suppliers filter the water from all debris and treat for bacteria, so most of this will be unnecessary (with the exception of the purple color pvc pipe, and valve boxes).
