(Ord. No. 1824-68.
Passed September 3O 1968.
Effective October 1, 1968.)
Depth
1. Cover over all 8" and 12"
pipe should normally be at least
6'‑0" from established
centerline grade and from the
top of ground over the water
main to the top of the pipe. All
16" pipe should have 5' of
cover. A variance of 1"‑0" above
and 2’ below is only permissible
while crossing over or under
obstructions. In certain cases,
where no connections are
involved and only when approved
by the Commissioner of Water CWD
Engineer minimum cover may be
less than 5’. deeper than 8’-0”
requires the use of bends.
Location
1. Water mains must be located a
minimum of 9'‑0" from the
property line or 10’-0” from the
easement line in the street or
easement in which it is to be
installed. Under this provision,
service stop boxes(curb boxes)
or meter vault manhole ring and
covers will not fall within
proposed sidewalk areas.
(“9'‑Rule) In no case should any
portion of the water main or
hydrants fall less than 5’ from
an easement or right-of-way
line.
2. In all allotment layouts,
water mains in proposed streets
must be extended to the further
most limit of the allotments .
(frontage rule)
3. Intersection pipe for future
streets must be installed to the
abutting property line, and a
line valve and box or flush pipe
installed at the property line,
as directed by CWD Engineer
Dead-Ends/Looping
1. All dead-end pipes, must have
a plug and complete 2" flushing
pipe assembly with box or
hydrant installed. (Tee hydrants
may be installed with a plug on
the hydrant tee)
Utility/Obstruction Clearances
1. Sewers-Sanitary
Water mains
shall be laid at
least 10 feet
horizontally
from any
existing or
proposed
sanitary sewer.
The distance
shall be
measured from
the outside of
the water main
to the outside
of the sewer.
One full length
of water pipe
shall be located
so both joints
will be as far
from the sewer
as possible with
a minimum of
1'-6" clearance
from outside to
outside of pipes
or structures in
a vertical
plane.
2.
Vertical/Lateral Clearance
*See detail
clearance.
3. Depths Over 7 Feet
To clear
obstructions
which result in
main being 8
feet or greater,
bends to be
used. Divisional
valves are to be
installed at
both ends to be
used in the
event of a water
main break. When
determined by
CWD Engineer,
usually large
streams, rivers,
large culverts,
freeways.
4. River Crossings
*See river
crossing detail.
Valves
General Location
1. Line valves should be
provided between 1,000 feet and
1,500 feet along run of pipe
between intersecting streets.
(If run between 2 streets is
1800’ then put a valve at 900’)
2. Valves installed between
intersections shall be located
one length of pipe from hydrant
tee on the run of the pipe.
3. For new mains, there must be
a minimum of two (2) valves at
tee intersecting streets and a
minimum of three (3) valves
installed at cross intersecting
streets. When looping is an
issue you can install 3 valves
at tee intersections and 4
valves at cross intersection.
Tapping Sleeves & Valves
1. An existing tee at an
intersection of proposed project
shall not be used. Normally the
existing tee is removed and a
new cut-in-anchor tee and valve
are installed. A tapping sleeve
and valve shall be installed so
that service to users will be
maintained whenever possible.
Boxes for tapping sleeves and
valves are to be supplied by the
Contractor.
2. Where a branch sleeve and
valve with valvebox is installed
on an existing main, if said
main is over 8 lineal feet from
the abutting property line, then
a line valve and box must be
installed at said property line.
3. Where a tapping sleeve, valve
and box are installed, the
connecting run of pipe must be
installed at right angles from
the distribution main to the
line valve located at the
property line. A bend will then
be installed, if necessary, to
align the run of pipe in the
proposed street or easement.
Service Divides
Where a change of service occurs
in an existing street or
allotment in which a water main
is to be installed, the
Hydraulic Division will
determine the location of the
point of service change and a
standard gate valve and box will
be required at that point in the
run of pipe. This valve will
then be kept closed during
normal service. In regulated
zones a pressure regulator may
be required.
Pipe Fittings
1. Vertical Bends: the maximum
vertical bend shall be 22 1/2
(1/16). Offsets may be used in
place of bends where possible.
90 bends should not be used.
2. Horizontal Bends: Where right
angle turns occur in run of
pipe, if main may be extended in
the future, a tee should be
installed and the unused branch
plugged and clamped instead of
using a 90 bend. 90 bends are
rarely used.
Thrust Restraints
Thrust Blocks
1. Thrust blocks (concrete
piers) are required behind all
tees, horizontal bends, and
hydrant elbows, the contractor
shall also install a concrete
thrust block behind all tapping
sleeves in which the nominal tap
is one half or greater than the
nominal diameter of the pipe to
be tapped. The concrete pier
behind the tapping sleeve, as
herein stated, is required on
all connecting mains and service
connections.
2. Thrust Blocks normally
installed where access for
concrete trucks is available.
Hydrants
Spacing
1. Hydrant spacing is 300' on
average (325’ maximum) in
accordance with ordinance
Section 535.36 in residential
areas. Commercial and industrial
streets an average spacing of
250' to 280'.
535.36 Size of Fire
Hydrants.
Fire hydrants shall be placed on
all new distribution water main
improvements or replacements of
existing distribution water
mains and shall be of six-inch
size having a six-inch nominal
diameter of the main valve
opening. Each hydrant shall be
connected to the water main with
a six-inch branch with gate
valve installed on each hydrant
branch approximately three feet
from the water main, and of the
same size as hydrant. Fire
hydrants shall be placed at
street intersections wherever
spacing will permit. Fire
hydrants in residential streets
are to be installed at the
center of sublots and spaced on
an average of 300 feet apart. In
commercial and industrial areas,
hydrants shall have an average
spacing of 250 feet apart, with
a maximum distance of 280 feet
apart. (Ord. No.
1824-68. Passed September 30,
1968. Effective October 1,
1968.)
Location & Setting
1. All hydrants must be
contained within the dedicated
right-of-way or easement lateral
limits, no closer than 5’ from
an easement or right-of-way
line.
2.
*See standard hydrant
details.
Abandonment
1. Where existing hydrants are
to be abandoned, they must be
plugged at the distribution
main. They cannot be plugged at
the hydrant valves.
Connections
NEW SERVICE CONNECTIONS REQUIRE
SEPARATE APPROVAL. NEW
CONNECTIONS SHALL BE SHOWN ON
WATER MAIN INSTALLATION PLANS AS
REFERENCE ONLY. CONTACT PERMITS
& SALES OFFICE REGARDING
APPROVAL FOR NEW WATER SERVICE
CONNECTIONS.
Abandonment
1. All inactive service
connections on allotment
frontage on abutting streets
must be plugged at main, unless
they fall within frontage of
subdivision and will be used.
Property lines must be shown to
determine use. The appropriate
call outs are to be added to
plan and profile sheets.
2. Where unused connections are
to be abandoned, they must be
plugged at the distribution
main. They cannot be plugged at
the water service stops.
New
1. No tees for water service
connections are to be installed
on new water main run. Taps for
connections will be made by the
Division of Water after the main
has been tested and chlorinated.
2. If an abandoned intersection
of pipe is to be converted to a
service connection feed in the
future, then a valve and box
must be installed on this line
at a point where the curb valve
would normally fall, as
determined by CWD Engineer. The
use of this pipe for such
purpose must be approved by the
Commissioner of Water. If
refused, then a separate tap
must be made for the connection
and unused intersection pipe
plugged at the main.
Location
1. Where a hydrant is located at
the end of a run of pipe, as in
cul-desacs, connections must be
taken off ahead of the reducer
on the hydrant branch. No
connection can be taken off of
the hydrant branch on feed
hydrants.
2. All connection vaults must be
contained within the dedicated
right-of-way or water main
easement lateral limits. In
situations approved by Division
of Water meter vaults can be
placed adjacent to the
right-of-way or easement in a
meter vault easement obtained
from the Permits & Sales Unit.
“Other Approvals”
1. Engineer for the local
municipality or water district
must sign off on at least four
copies of the plans prior to
final stamping by CWD.
2. OEPA must review and approve
plans for “substantial changes
to the water distribution
system. We receive a letter from
OEPA when they have approved the
plans. Construction is, by law,
not permitted to start until
approval by OEPA is granted.
