C3.3. CRITERIA
C3.3.1. General Requirements. DoD water systems, regardless of whether they produce
or purchase water, will:
C3.3.1.1. Maintain a map/drawing of the complete potable water system. When the
installation produces drinking water, potable water distribution system maps shall be updated
every year (or sooner, if there are changes).
C3.3.1.2. Update the potable water system master plan at least every 5 years.
C3.3.1.3. Protect all water supply aquifers (groundwater) and surface water sources
from contamination by suitable placement and construction of wells, by suitable placing of the
new intake (heading) to all water treatment facilities, by siting and maintaining septic systems
and onsite treatment units, and by appropriate land use management on DoD installations
through the adoption of the following zoning criteria:
C3.3.1.3.1. Zone of Absolute Conservation: The area immediately surrounding
wellheads and associated piping. Zones of absolute conservation shall be adequately protected,
have a radius of at least 10 meters (33 feet) from the withdrawal points and be used only to host
the pumphouse and related utilities. The wellhead should be placed in a pumphouse with access
limited to authorized personnel. The pumphouse shall have the size and dimensions to facilitate
inspections. The pumphouse should be equipped and constructed to avoid water stagnation on
the floor or infiltration from walls or roof. The wellhead closing shall be equipped with a
sampling port with a threaded plug in order to facilitate groundwater level measurements and
direct sampling.
C3.3.1.3.2. Zone of Respect: The area surrounding the zone of absolute
conservation. Lacking the definition by the Region of the extension of the zone of respect, the
zone itself is assumed to have a 200-meter (656-feet) radius from the withdrawal point. The
following activities are prohibited in the zone of respect:
C3.3.1.3.2.1. Discharge of waste, sludge, or sewage, even if purified
C3.3.1.3.2.2. Storage of organic or chemical fertilizers or pesticides
