The GBA Sewer Master
and GBA Work Master
programs are integrated
in several ways. A work order is created in GBA Work Master
specific sewer item (or group of like items). Pertinent information for the item
is automatically brought into the work order record from the appropriate GBA
inventory module. For a sewer pipe, this information includes
upstream and downstream manhole numbers, length, slope, diameter, liner, and
material. Any updates to the item's inventory information determined to be
necessary from observations/modifications made during completion of the work can
be automatically made directly from the work order record in GBA Work Master
From a click of a toolbar button in GBA Sewer Master you can view work
order histories on any pipe segment or manhole, as well as see work orders that
have been assigned but not completed.
Horizontal coordinate data for each sewer item, used by the GBA GIS Master
program to define the system's mapping, are stored in the inventory modules of
the GBA Sewer Master program. These items, along with their pertinent
inventory information, can then be viewed graphically through GBA GIS Master
at their defined locations. Inspection and analyses results from GBA
Sewer Master can also be viewed graphically through GBA GIS Master.
The integration of GBA Sewer Master with GBA GIS Master enhances
the user's ability to detect trends in system deterioration, locate possible
capacity bottlenecks, or map inspection routes for work crews. The combination
of these two programs provides the foundation of a well-managed system.
System Inventory is the core of the GBA Sewer Master suite of programs.
These modules contain all inventory information commonly found on a set of
construction drawings. The Pumps and Pump Stations module also incorporates
inspection and testing information with inventory data. The Service Lateral
module includes the ability to track permits and costs for sanitary sewer
connections. The modules include:
Pumps & Pump Stations
The System Inspections modules enable you to track the results of Sanitary Sewer
Evaluation Studies (SSES), Infiltration and Inflow (I/I) inspections, or
day-to-day maintenance inspections.
The Television Inspection module stores television inspection data obtained
by viewing and rating televised line segments. The analysis of this data
provides an indication of the structural integrity of the sewer system. The
module analyzes the TV observation data and assigns a flow, structural, and
cleaning priority number for each line segment, allowing for quick
prioritization of system improvements.
The Manhole Inspection module contains a detailed condition rating for each
portion of the manhole. This information provides for identification of I/I
sources and documents the structural conditions of the manhole. It also provides
the foundation for the establishment of a manhole rehabilitation program, thus
expediting manhole rehabilitation improvements.
The Line Lamping module contains information on the physical inventory and
condition of each sewer segment as determined by line lamping during manhole
inspections. This information is valuable for identification of line defects and
provides a basis for recommending cleaning and television inspections. In
addition, rim-to-crown measurements are recorded for each pipe entering or
exiting the manhole.
The Smoke Testing module contains observations of inflow sources identified
by smoke testing. Positive findings indicate the existence of inflow sources.
The Building Inspection module contains current information from
home/business owners regarding previous/current flooding conditions, the status
of sumps and sump pumps, and suspect sources of infiltration and inflow
identified during building inspections.
Dyed-water testing information is stored in both the Smoke Testing and
Building Inspection modules. Stored data consists of the observations,
measurements, and records of information for each dyed-water test completed.
Sources of inflow are also quantified.
The Joint Testing module contains information about the strength and
conditions of the pipe seal joint. As pipe seals are tested, their condition is
rated. If the seal does not pass, repair steps are documented.
The Flow Isolation module allows you to track your activities in pinpointing
areas of heavy infiltration.
GBA Sewer Master's analysis modules go beyond simply tracking
inventory and inspection information to take advantage of all collected data to
help effectively rehabilitate the collection system.
Manhole Rehabilitation Analysis
Designed to help engineers fast-track system improvements, this module takes
comprehensive manhole inspection information and assigns rehabilitation tasks to
the appropriate manholes. When rehabilitation or replacement is scheduled, work
orders can be generated. The results of the completed work then update the
manhole rehabilitation module as well as the manhole inspection module.
Pipe Rehabilitation Analysis
Similar to the Manhole Rehabilitation module, this module focuses on point
repairs, line segment rehabilitation, or line segment replacement based on the
results of television inspection data.
GBA Flow Master
GBA Flow Master is designed exclusively for the analysis of sanitary
sewer systems. This easy-to-use package can locate system bottlenecks or
determine the impact of new development on the system. Planning-level costs to
parallel and/or replace overloaded line segments are calculated. By broadening
the parameters involved, GBA Flow Master takes the analysis of a
sanitary sewer hydraulic system to the limit.
The Field Inspection module provides your field crews with a blank database,
allowing them to record their inspection data as they perform the inspections.
This process eliminates the use of field forms and time-consuming data entry,
and prevents any discrepancies in your data. The data collected in the field is
then transferred to the master database and run through a series of validations
to ensure the data's integrity.
