Re: Inflow/Infiltration Reduction Program
S&P Proposal No. G01-0006
Dear Mr. Hicks:
Stevenson & Palmer Engineering, Inc. is pleased to offer this proposal to provide
investigative services for Augusta's inflow and infiltration reduction program.
Stevenson & Palmer understands that AUD desires assistance in identifying
defects that allow the entry of extraneous flow to the sewer system. We also
understand that AUD wishes Stevenson & Palmer to focus on the sanitary sewer
system north of the Gordon Highway, beginning in the Rae's Creek basin.
We believe that the quickest and most cost-effective means of identifying
sources of inflow and infiltration are through a combination of physical
inspections, flow monitoring, and smoke testing of the sanitary sewer system.
Stevenson & Palmer currently has 4 area/velocity flow meters, a logging rain
gauge, and smoke testing equipment to utilize in this effort.
We propose to perform flow monitoring at strategic points in the collection
system, to be identified with the assistance of AUD staff. Flow monitors will be
left in place to monitor system response to one or more significant rain events.
Following analysis of the flow data, the meters will be relocated to isolate sub-
areas that exhibit the most significant wet weather response. Once problem
areas have been sufficiently isolated, defects will be identified through physical
inspections and smoke testing. This proposal does not include CCTV inspections
services, however, Stevenson & Palmer will coordinate with AUD's staff when
these efforts are required.
Project deliverables will include results of flow monitoring in graphical format and
monthly progress memorandums detailing investigative efforts and system
defects identified.
