ensure that the disinfecting solution is present at a concentration within the specifled
range throughout the piping system.
C. Procedure for Disinfecting Water Mains and Appurtenances
1. The pipeline shall be filled at a rate not to exceed 1,135 liters per minute (300 GPM) or a
velocity of 0.3m per second (1 foot per second), whichever is less.
2. Disinfection shall result in a total chlorine concentration of not less than 25-mg/l.
This concentration shall be evenly distributed throughout the system to be disinfected,
using a continuous feed method of chlorination.
3. All valves shall be operated with the disinfection solution present in the pipeline. All
appurtenances such as air-vacuum relief valves, blowoffs, hydrants, backflow prevention
devices, and water service laterals shall be flushed with the treated water a sufficient
length of time to ensure a chlorine concentration within the specifled range in all
components of each appurtenance. (Note the limitations for discharge of chlorinated
water outiined below.)
4. The Engineer will verify the presence of the disinfection solution throughout the system
by sampling and testing for acceptable chlorine concentrations at the various
appurtenances and/or at the test ports provided by the Contractor. Areas of the system
found to be below the specifled chlorine concentration level shall receive additional
flushing as noted above and/or additional disinfection solution as necessary. (Note the
limitations for discharge of chlorinated water outlined below.) Addition of disinfection
solution after the initial charging of the line shall be made by either the liquid chlorine
(gas) method, or the sodium hypochlorite method as directed by the Engineer.
5. The chlorinated water shall be retained in the system for a minimum of 24 hours. The
City Engineer will test the total chlorine residual. The system shall contain a total
chlorine residual of not less than 80% of the initial total chlorine residual before the 24-
hour soaking period began. If the total chlorine residual has decreased more than 20%,
the system shall be soaked for an additional 24-hour period. If the total chlorine residual
has not deceased after this additional 24-hour period, the system shall be flushed in
accordance with the procedure detailed herein. If the total chlorine residual has
decreased, the system shall be flushed in accordance with the procedure detailed
herein, and shall be re-disinfected.
6. Following a successful retention period as determined by the City Engineer, the
chlorinated water shall be flushed from the system at its extremities and at each
appurtenance, using potable water from a source designated by the City Engineer. The
minimum water velocity during flushing shall be 0.9 meters per second (3 feet per
second) or as directed by the Engineer. Flushing shall continue until the replacement
water in the new system is equal in chlorine residual to the potable source of supply as

2. In locations where chlorine neutralization is required, the reducing agent shall be applied
to the water as it exits the piping system. The Developer shall monitor the chlorine
residual during the discharge operations. Total residual chlorine limits in these locations,
and for the discharge of chlorinated water from the testing of pipelines to surface waters
of the San Diego Region are as follows:
Total Residual Chlorine Effluent Limitations
30-Day Average 0.002 mg/1
Average Daily Maximum 0.008 mg/1
Maximum 0.02 mg/1
3. The various methods of dechlorination available can remove residual chlorine to
concentrations below standard analytical methods of detection, 0.02 mg/1, which will
assure compliance with the effluent limit. The Developer will perform all necessary tests,
keeping and providing records to the Engineer to ensure that the total residual chlorine
effluent limitations listed above are met.
4. In locations where no hazard to the environment is evident. based on the joint
examination described above, the chlorinated water may be broadcast for dust control
on the surface of the immediate site. Care shall be exercised in broadcasting the water
to prevent runoff.
E. Bacteriological Testing
The Contractor shall employ a State certified laboratory to perform bacteriological sampling and
testing of all new system installations. The testing methodology employed by the City shall be

PART 3 EXECUTION
A. Steps for Meter Replacement
6elow are the steps an installer is to follow at every subject meter setting:
1. Setting Identification - Upon arrival to a designated meter site, installer shall verify location
by matching address, whenever possible, and the serial number of meter on the Service Order
form to meter in box. If numbers match, the installers can proceed. Should there be a
discrepancy between exchange sen/ice order form serial number and subject meter number,
installer shall verify street location and note discrepancy on exchange sen/ice order form.
Inspection of register shall also be made at time of initial identification to determine any usage
on sen/ice location at that time. Identify existence and condition of meter couplings, if
nonexistent or in bad shape, skip meter and report to District within 24 hours.
2. Cleaning of Meter Box - Installer shall clean dirt and debris out of meter box to ensure enough
space to replace meter without getting dirt and debris inside of meter.
3 Customer Contact - Before water is shut off installer will make contact with customer to
advise them that the water is about to be turned off. In the case of single-family residence
installer shall knock on all customer doors and advise them of the nature of their visit and that
water service will be interrupted for a short period of time. If no one comes to the door and
movement of meter is present, installer shall bypass setting temporarily and return a short time
later. Should no one be home and the meter is not indicating flow, installer shall proceed with
meter exchange. In cases where customer refuses to have meter replaced, skip locations and
make a note on the service order as such and report to District within 24 hours.
4 Isolation at House and Business - After customer notification, installer shall locate customer
house or building shut-off valve and depending on condition of house or building valve, close.
(NOTE: Debris in meter pit should be removed prior to disruption of water service). Care should
be taken when operating customer's valve, extreme force should not be used to open or close
the valve. If valve is not operating, change meter with valve open. All debris from meter pit is
to be removed prior to leaving each job site.
5. Isolation at Curb - Installer shall place safety cones at curb and walkway. Installer shall then
shut off inlet curb valve taking care not to make abrupt movements that may damage valve.
District will conduct training on various shutoff valves. A shut off tool designed specificallv
for turning water service valves must be used at all times.
NOTE: IF THE CURB STOP IS FROZEN OR DIFFICULT TO OPERATE, SKIP AND REPORT
TO DISTRICT: DO NOT USE FORCE. ALSO, IF SHUT OFF VALVE IS IN THE OFF
POSITION PRIOR TO REMOVAL OF METER, VALVE WILL NEED TO BE PUT BACK IN
THE SAME POSITION AFTER INSTALLING THE NEW METER AND THE LINE HAS BEEN
FLUSHED.
6. Removal of Meter - With line isolated, installer shall use appropriate wrenches to loosen
meter couplings. Final reading on old meter is to be written on the side of new meter with
permanent marker.
7. Installation of New Meter - New meter shall be installed in place of removed meter with
new meter gaskets. If there is a 1 1/4" x 1" bushing attached to meter it is to be reused
NOVEMBER 2014 CONTRACT 6608, 5019, 6001 & 6013 WATER METER
GRAND AVENUE IMPROVEMENTS SECTION 15059-2
(It may be necessary to replace the gasket within the bushing). If the bushing cannot be
reused replace it with a new one. Gaskets and bushings to be supplied by the District.
Contractor is responsible for any meters installed backwards. The District will back-
charge the Contractor for consumption of all meters that are installed backwards and
for the time spent for correction.
8. Flushing of Line - Installer shall locate the hose bib nearest to the meter. Hose bib valve shall
be fully opened by installer then curb stop will be partially opened for approximately 10 to 15
seconds to remove any dirt or debris and then taken to a full open position with full discharge
of water at the hose bib. The flushing process shall continue until water clears and any
entrapped air has a chance to evacuate the line. This shall take an additional 10 to 20 seconds,
depending on line size and proximity of hose bib to meter site. Flush the water as to not cause
damage to landscaping. With flushing complete, hose bib can be shut down and once
pressurization occurs, check for any sign of leakage and movement.
9. Customer Notice- Should meter continue to indicate flow after turning water back on Installer
shall try to make contact with customer. If customer cannot be contacted the Installer shall turn
the water off at the customer's valve (or curb valve if customer's valve is not functioning) and
leave a blue door tag on front door explaining why the water is off. Door tag will be provided
by CMWD.
10. Installation of Endpoint - Contractor shall plug the connector coming off of meter register
into the lower receptacle of the Itron 100W endpoint. Security clip shall then be attached.
Endpoint shall then be secured in box by placing it in an upright position on fixed bracket on
the side of the meter register or on pipe supplied by the District.
11. Completion - Contractor shall make every effort to restore site to its original condition. This
shall include clean-up of all debris (in and outside of box), maintenance of foliage/trees with
minimal damage, etc.
Contractor shall be responsible for any meter leakage after new installations for a period
of one full billing cycle (30 days).
6. Workday Completion
At the end of each workday, and no later than the next morning, the Contractor (Project Manager)
shall transmit the completed Sen/ice Order Forms to the Inspector or Project Manager. Meters will
be returned to the District's yard, location to be determined by Project Manager. Care should be
given to all old meters not to damage the register as the reading may need to be verified at a later
date.
The Contractor shall be responsible for turning in all meters; in the event that an old meter is not
turned in, a salvage fee twice the current scrap value will be charged to the Contractor for that
meter. If a new meter is not turned in or installed, the Contractor will be charged for the cost of the
meter.
C. On-Site Support
During the replacement program if any breakage occurs to customer's sen/ice line, the Contractor
is responsible for making the necessary repairs to these lines. Sen/ice line is described as pipe
that runs from the back of the customer handle valve in meter box to the entrance to the customers
dwelling or place of business. Contractor is responsible for any customer service line
breakage for 30 days after meter exchange. Contractor must have appropriate pipe and fittings
in the field to make the repairs in a timely manner. In the case that there is breakage to the District's

GRAND AVENUE IMPROVEMENTS SECTION 15061-9
fittings in the trench shall be closed during any interruption to the work as noted
above.
e. Pipe shall be laid directly on the bedding material. No blocking will be permitted, and
the bedding shall be such that it forms a continuous, solid bearing for the full length
of the pipe. Excavations shall be made as needed to facilitate removal of handling
devices after the pipe is laid. 6ell holes shall be formed at the ends of the pipe to
prevent point loading at the bells or couplings and to permit visual inspection of the
joint. Excavation shall be made as needed outside the normal trench section at field
joints to permit adequate access to the joints for field connection operations and for
application of coatings on field joints.
f Installation Tolerances: Each section of pipe shall be laid in the order and position
shown on the approved layout schedule to the proper lines and grades in
accordance with the following:
• Each section of pipe having a nominal diameter less than 48" shall be laid not to
vary more than 0.2-ft horizontally or 0.1-ft vertically from the alignment and
elevations shown on the Approved Plans.
• Each section of pipe having nominal diameter 48" and larger shall be laid not to
vary more than five percent (5%) of the pipe diameter horizontally or two and one
half percent (2.5%) ofthe pipe diameter vertically.
• In addition to the horizontal and vertical tolerances above, lay the pipe so that no
high or low points occur along the pipeline other than those shown on the
approved layout schedule.
4. Where necessary to raise or lower the pipe due to unforeseen obstructions or other
causes, the Engineer may change the alignment and/or the grades. Such change shall
be made by the deflection of joints, by the use of bevel adapters, or by the use of
additional flttings. However, in no case shall the deflection in the joint exceed seventy
five percent (75%) of the maximum deflection recommended by the pipe manufacturer.
No joint shall be deflected any amount that will be detrimental to the strength and water
tightness of the finished joint. In all cases the joint opening, before finishing with the
protective mortar inside the pipe, shall be the controlling factor.
5. Pipes shall be laid uphill on grades exceeding 10 percent. Pipe that is laid on a downhill
grade shall be blocked and held in place until the following pipe section has been
installed to provide sufficient support to prevent movement.
6. Temporary internal pipe bracing shall be left in place in pipe sizes larger than 24" until
pipe zone compaction has been completed. 6racing in pipe smaller than 24" may be
removed immediately after the pipe has been laid into the trench. The Contractor shall
employ a laboratory to monitor pipe deflection by measuring pipe inside diameter before
bracing is removed and 24 hours after struts are removed. Pipe deflection shall not
exceed 3 percent in 24 hours after the bracing has been removed. After the backfill has
been placed, the struts shall be removed.
7. Cold Weather Protection: No pipe shall be installed upon a foundation onto which frost
has penetrated or at any time that there is a danger of the fonnation of ice or penetration
of frost at the bottom ofthe excavation. No pipe shall be laid unless it can be established
that the trench will be backfilled prior to formation of ice and frost.

placed around the joint and tightened securely to prevent leakage while the mortar is
being poured. The diaper shall be made of moisture resisting paper or heavy duty sail
cloth of sufficiently close weave to prevent cement loss from the mortar. The diapers
shall be hemmed on each edge and shall contain a metal strap within each hem
sufficiently longer than the circumference of the pipe to allow a secure attachment of the
diaper to the pipe. The diaper width will depend upon pipe size and design and shall be
the width recommended by the manufacturer. Following installation of the diapers, the
joints shall be poured and redded from one side only until the mortar comes up to the top
of the diaper on the opposite side. Approximately one hour subsequent to the pouring of
the joint, the joint shall be rechecked and, if any settlement, leakage or shrinkage has
taken place, the joint shall be refilled with mortar.
5. Outside joints may be grouted before or after the placement of bedding and backflll
materials if those materials are to be mechanically compacted. If bedding and backfill
materials are to be hydraulically densified, grout shall be poured and allowed to set
before applying water. In any case, joints shall be grouted before backfill is placed over
the top of the pipe.

Re; EA 13-03 - NORTHWEST QUADRANT STORM DRAIN PROGRAM - GRAND AVENUE
Thank you for submitting an Early Assessment to install and repair/replace the stornn drain pipe and
appurtenances at Grand Avenue, which starts approximately 150 feet east of the intersection with
Madison Street and connects to the twin 48 inch pipes at the State Street alley. Per RBF Consulting, in
their Hydrology and Hydraulics Report, dated March 8, 2013, the piping is undersized which results in
flooding in this area. No new impervious surface is proposed with this project. The increased pipe will
not result in an enlargement or expansion of the stormwater capacity in this area.
The proposed project includes the following pipe and appurtenances:
• Install 850 lineal feet of 48- inch reinforced concrete storm drain pipe
• Install 280 lineal feet of 36- inch reinforced concrete storm drain pipe
• Install 80 lineal feet of 18- inch reinforced concrete storm drain pipe
• Install five (5) curb inlets
• Install six (6) storm drain clean outs
• Resurface trench areas
• Remove and replace 200 square feet of sidewalk
• Relocate potable water system including water main and fire hydrant
• Install bio-retention cells
• Remove and replace approximately nine trees
