treatment for irrigation, such requirement will be complied with. The effluent irrigation system
must be physically separated from any distribution systems carrying potable water. A detailed
plan will be provided showing the location of the effluent irrigation system in relation to the
potable water distribution system and buildings. Provision will be made either for locking the
sprinkler irrigation control valves or removing the valve handles so that only authorized
personnel can operate the system. In addition, readily identifiable "nonpotable" or
"contaminated" notices, markings or codings for wastewater conveyance facilities and
appurtenances will be provided. Another possibility for reuse of treated effluent is for industrial
operations where substantial volumes of water for washing or cooling purposes are required.
For any re use situation, great care must be exercised to avoid direct cross connections
between the reclaimed water system and the potable water system.
c. Review of effluent irrigation projects. Concept plans for proposed irrigation projects
using wastewater treatment plant effluent will be reviewed by the engineer and surgeon at
Installation Command level and the Air Force Major Command, as appropriate. EM
1110-1-501 will serve as the basic criteria for such projects, as amended by requirements
herein. This publication is available through HQ USACE publications channels. Such projects
will only be authorized after approval by HQDA (DAEN-ECE-G), WASH DC 20314 and HQDA
(DASG-PSP-E), WASH DC 20310 for Army projects and by HQUSAF (HQ USAF/LEEEU),
WASH DC 20332 and The Surgeon General, (HQ AFMSC/SGPA), Brooks AFB, TX 78235 for
