Location of Spray Irrigation Disposal Systems.
1.
All components of the spray irrigation disposal system shall be located a minimum of:
a.
Five (5) feet from any dwelling or permanent structure.
b.
Ten (10) feet from any property line.
2.
The Advanced Treatment System and pump/dosing chamber shall be located a minimum
of fifty (50) feet from any public, private or individual potable water source.
3.
Potable water lines and wastewater lines shall not be laid in the same trench. The potable
water lines and wastewater lines shall maintain a minimum horizontal separation of 10
feet. Where a potable water line must cross a wastewater line, the potable water line
within ten (10) feet of the point of crossing shall be at least twelve (12) inches above the
wastewater line.
4.
Spray Irrigation systems shall not be located in depressed areas where surface water will
accumulate. Provisions shall be made to minimize the flow of surface water over the
effluent disposal field.
5.
There shall be maintained, from the outer edge of the spray pattern, the following
distances:
a.
One hundred (100) feet from any public, private or individual potable water
source, located at a lower elevation.
b.
Fifty (50) feet from recreational waters, shellfish waters or other sensitive areas
for spray fields located on slopes of less than eight (8) percent or if the soil texture
is sandy loam or lighter or sandy clay or heavier.
c.
Seventy five (75) feet from recreational waters, shellfish waters or other sensitive
areas for spray fields located on slopes of greater than eight (8) percent or if the
soil texture is sandy loam or lighter or sandy clay or heavier.
d.
Twenty five (25) feet from dwellings, swimming pools, businesses or other
inhabited structures.
e.
Twenty five (25) feet from lot lines, porches, patios and decks.
f.
Fifteen (15) feet from outbuildings.
g.
Ten (10) feet from walkways, private roads, driveways and parking areas.
h.
Effluent should not be sprayed upon any vessel containing wastewater.
6.
Where all or part of the Spray Irrigation system is proposed to be installed on property
other than the owner’s, an easement in perpetuity shall be legally recorded in the proper
county and a copy furnished to the local county Health Department prior to listing Spray
Irrigation as an option. The easement shall be of sufficient area to permit access,
construction and maintenance of the system.
7.
It is the intent of these regulations that a minimum separation of fifty (50) feet between
independent spray disposal fields be maintained. Overlapping of the required setback
from property lines cannot be negated by the granting of easements.
8.
In soils that contain a restrictive horizon (fragipan, chalk, bedrock, clay or silty clay)
within two (2) feet of the surface, there shall be maintained a minimum of six (6) inches
of unsaturated soil between the Seasonal High Water Table.
9.
In soils that do not contain a restrictive horizon (fragipan, chalk, bedrock, clay or silty
clay) within two (2) feet of the surface, there shall be maintained a minimum of twelve
(12) inches of unsaturated soil between the Seasonal High Water Table.
