Dear Ms. Neckas:
SUBJECT: BACKFLOW PREVENTION DEVICE TESTING
The backflow prevention device in your water supply
system is due for annual testing as required by State Code
WAC 248-54-500. Our records show a total of one device in
your system. Please have the testing performed by a person
holding a certificate of competency as a cross connection
specialist, issued by the State Department of Social and
Health Services (telephone - 464-7674).
If a device fails its test, please have the necessary
repairs made. Upon completion of a satisfactory test, have
the certified tester fill out the enclosed Test and Maintenance
Report and return it to this office within thirty days.
Additional information relative to this matter may be
obtained by contacting our Cross Connection Control Specialist
at 771-3202, extension 294.
Sincerely,
ARCHIE BRENA

The capacity of the channel depends on
whether it is designed solely to in-
crease time of concentration, or also
to protect downslope installations.
Channel cross sections should be de-
signed so -that they may be basically
maintained by machinery. Usually this
Runoff Spreader. The function.of a
runoff spreader is to disperse runoff
at nonerosive velocities over undis-
turbed areas stabilized by existing
vegetation. Concentrated runoff is
changed to sheet flow, much of which
will infiltrate in undisturbed areas.
The spreader should be constructed on
undisturbed soil which is neither
poorly drained nor highly erodible. it
