electrolytic effects on their service pipe
system. A like action, but of far less
extent, is observable within the vicin-
| ity of the Traction Electric Power sta
ton. An improved form of rail bonding
has lately somewhat obviated this diff
Guilty, but deteriorating effects will be
observable as long as the electric sur
rent will find its way toward the water
mains.
! Summarized by sections of the city ter
ritory, all cast iron pipes are good, all
wrought iron and sheet iron pipes in the
northwesterly and northeasterly sec
tons of the city are subject to more or
| less quick deterioration within the adobe
| soil, while in the sections south of Sew
enth street, these pipes have compare
| lively longer term of life, but none in
my opinion to exceed fifteen years of
usefulness.
| All observations in regard to condi-
tions of pipe here quoted relate to eff
fects of soil and climate as observable at
the exterior of the pipes.
The interior of the pipes could be in
vestigated only in a few instances, and
no damaging incrustations nor tubercu-
losis was observed and none is to be an
ticipated, except in the case of the Pinch
ard 3-inch wrought-iron screw pipes
The Investigations made for the pur-
pose of verifying the conditions of the
pipes, are necessarily but indicative of
the general condition of the pipe system
in so much as the haphazard manner of
selecting the points where the pipes
were uncovered, at best could but indi-
% OF u 80
particular spots and their immediate
vicinity.
In all cases, however, where worth
less and badly rueted pipe was found,
the extent of such deterioration was
traced, if possible, to its limit.
BAD CONDITION
Out of the 31S pipes investigated, the
following are in very bad conditions: On
New High street north of Temple, 49,
inch sheet-iron main, badly corroded,

Central, north of Seventh, 4-inch cast
iron pipe corroded by alectrolysis. Cen
trail south Of Eighth, 4-inch cast-iron

trolysis. Central, corner of Wilde. two
4-inch pipes and Pinch pipe deteriorated
by rust and electricity. Fifth, east of
San Pedro, 4-inch cast-iron pipe shows
electrolytic effect on side nearest the
street car track, Northwest corner of
Fifth and San Pedro, 6-inch castiron
pipe, nine years old, almost entirely
ruined by electrolysis; must >be renewed
shortly. Fifth west of Gladys, 4-inch
cast-ron pipe, shows electrolytic effect.
Third, east of Los Angeles, 4,inch cast
iron pipe, lead joints of pipe are de-
!,
Third, Pinch pipes corroded. Hewitt
and Second 4-inch cast-iron pipe and
two Pinch pipes, all show effects of rust.
