Subject: Electrical service outage to Prosser areas on Saturday,
June 7 , 1986
Following is a description of an electrical outage that affected Prosser
Heights, Prosser Lakeview Estates, Pannonia Ranchos and the area around
Coachland Mobile Park.
1. Truckee _Substation feeder 5 relayed to lock-out at approximately 12:00
noon.
I
2. On-call Lineman-Denny Devine and Apprentice Lineman Mike McGovern.fWound
the recloser open at the substation with indication of a three.phase fault
on the circuit.
3. The crew patrolled those accessible portions of feeder 5 out to Alder
Drive and fused disconnect 206 (F-206). These fuses were intact indicating
the problem was between there and the substation.
4. The crew then began a cross country patrol back towards the substation
and found two fuses blown at fused disconnect 210 (F-210) feeding the
Coachland area. This section was disconnected from the circuit.
i
5. The crew then closed the feeder 5 recloser successfully, picking up
feeder 5 except for that portion beyond F-210.
6. The crew then patrolled the circuit past F-210 and found no problem.
7. Returning to disconnect pole F-210, the crew found a broken down guy.
i
8. The crew then refused F-210 successfully. At this point all service
was assumed to be restored.
i
9. Denny returned home and contacted the answering service to inform them
1
r
I
I
i
that power was restored and found some customers in Pannonia Ranchos still i
had no power.
10. Denny then returned to F-216 on Alder Drive and , upon buzzing the
line, found one phase dead.
11. He began a patrol back towards I-80 and found an aluminum jumper had
burnt in the clear at a hot tap just north of I-80.
i
I
12. Lineman Manny Lopez was called out to assist and , after a brief
one-minute outage to the entire circuit , the hot tap was repaired.
13. All service was restored at approximately 4:00 P.M.
I
Conclusion
The initial cause of this interruption appears to have been a loader or
other equipment contacting and breaking the down guy at disconnect F-210.
The additional problem of the burnt jumper was caused by the resulting
short circuit-current-and a high resistance connection between the aluminum

MEMORANDUM
Date: June 20, 1986
To: Peter Holzmeister, General Manager
From: Keith Sauers, Consulting Engineer
SUBJECT: WATER SUPPLY TO PROSSER LAKEVIEW ESTATES
Several times last summer and twice during the past month District
customers have experienced loss of water in portions of this system.
By installing a recording pressure sensor last year and interpreting
the resulting chart of system pressure we were able to determine that
the immediate cause was a sudden large demand at some location, lasting
about 20 minutes. With this information your staff watched for and
�.. apprehended the next contractor filling a water wagon from this system
without permission from the District.
On the Monday after Memorial Day this year and again last week
contractors were caught in the act of filling water wagons from the
hydrant near-Sanders Well, without permission. A water user in the
upper zone of Prosser Lakeview Estates told me he was without water
for over two hours during the Memorial Day incident.
I have discussed with you the computer model I have been preparing of
this particular water system. The model at this point is not complete,
but preliminary indications are that (1) the source of supply is not
adequate to serve peak demands at the present level of development
(estimated to be 50%) and (2) the pipelines are not adequate to trans-
port peak hour flows. Additionally, I suspect the storage is inadequate,
but have not yet confirmed this. A 1976 Water System Analysis Report,
prepared by Cook Associates, offers the following:
Prosser Lakeview Estates - Units 4 and 5: The Developer
was required to install a 200,000 gallon tank along with
a booster pump and pressure regulators. The District
later exempted the Developer from these requirements. The
District members now have the obligation to provide these
facilities along with the installation of a pipeline to,
and a pump at the Prosser Well.
When contractors request water for water wagons the Water Department
Foreman individually approves each location, in order to avoid any
adverse impact in the water system.
Memorandum
Peter Holzmeister
June 20, 1986
PAGE TWO
The fact that the prompt loss of only 3,000± gallons from the Prosser
Heights - Prosser Lakeview Estates system causes water outages suggests
(1) the system will probably not provide fire protection on a summer
weekend at present levels of development and (2) the system inadequacy
should be analyzed and budgeted for correction.
I would request at this time authorization to proceed with engineering
necessary to identify the problem and determine corrective action. I
estimate the cost of engineering services to be less than $2,000.

Each week the water Department samples various points within the
distribution system. The water samples are taken to Cranmer Engineering
for analysis. On a monthly basis, a Bacteriological Summary Report is
�— provida&,• ttr-the4Sta�rtment of Health. The report indicates the
p _whi ch.have-_positi-ve__coliform. count. A small
pew wiliq es is allowed.

the Aanks: # ted areas. Samples taken°:during the second

Of twelve points sampled during the third and fourth weeks of June, eight
located imjaho�-_ Donner, Donner Trails and Gateway had positive counts.

ment represm #eve, Jess Morehouse. Chlorination of all tanks serving the
affected areas as continued, although the injection chlorinator located
at the Northside Well failed for a one week period.
There are several contributing factors to the presence of coliform within
the system at this time:
1 . Failure of the chlorinator at the Northside Well ;
2. Disturbance of sediment within the tanks and distribution
system as a result of increased useage and the startup
of larger pumps installed as a part of the 1986 Pump
0'1 Station Expansion project;

3. Disturbance of algae within the tanks as a result
of increased useage; Algae formation occurs as a
result of warmer air temperature.
Recent analyses indicate that the chlorination has been effective in
destroying the coliform within the system. The monthly report is used
as an indicator for meeting drinking water standards. Public notification
is required when the allowable percentages are exceeded. Although none
of our sources indicate the presence of coliform, the District must send
notice to our customers of the failure to meet drinking water standards
for the month of June. The notice is for information purposes only, and
is not considered an emergency notification.
I
The areas we must notify include the following subdivisions:
Tahoe Donner Gateway Armstrong
Sierra Meadows Martiswoods Estates Martis Valley Estates
Ponderosa Palisades Meadow Park Ponderosa Fairway Estates
River Streets Donner Trails Ponderosa Ranchos
Olympic Heights Deerfield Downtown 7Vr-:kee
The Health Department is concerned over the repeated failures during the
summer months. Since the increased production during-summerinonths is
inevitable,-as is the warm weather, _c6lorinat-i-on-on a--regular bast-.appears--
to be our only recourse. A .letter ring .the.publ iz-notification and a
request for the installatioapof pe�dilorinatiow-�lacii=sties--swill be
