A Major Technological and
Economic Breakthrough in Detecting
and Locating Inflow & Infiltration

During the past 5 years, the average National
wastewater treatment rate to U.S. taxpayers
has risen 28.6%.*
There are approximately 18,500 municipalities in the United States producing
40 billion gallons of wastewater per day at a taxpayer cost of $150,000,000 or
$55 billion dollars annually. A study by the Association of Metropolitan Sewage
Agencies claims that 25% of this 40 billion gallons per day, or $14 billion
annually, is due to inflow and infiltration (I&I) of ground and storm water, the
cause of which is directly linked to our aging and faulty sewer infrastructure.

iTracker Ushers in a New Age of
Wastewater Infrastructure Analysis
iTracker Inflow and Infiltration (I&I) Detection Systems from Eastech Flow
Controls introduce a breakthrough technology that now makes it economically
feasible for every municipality in the country to cost-effectively reduce their
wastewater treatment charges. iTracker’s advanced technology is based upon
a unique algorithm designated as “Delta Q”. Delta Q (patent pending) provides
for the ability to compute volumetric differences in wastewater flows between
dry and wet days, except without the requirement for ascertaining pipe slopes
and coefficients of roughness.
This single proprietary feature allows for the elimination of confined
space entry, installation in 20 minutes, zero maintenance and immediate
cost savings of up to 80%.

Inflow & Infiltration
Detection Systems
iTracker paves the way for municipalities to begin the process of realizing
substantial decreases in their wastewater treatment charges at a
fraction of the cost of conventional methods. The major economic
advantage of iTracker lies in its ability to detect and locate at a minimal
cost millions of additional gallons of ground and storm water that enter
the collection system due to inflow and infiltration. This unique ability for
locating I&I creates the potential for reducing a municipality’s treatment
costs by hundred of thousands of dollars.
The Establishment of an Advanced Concept
There are approximately 18,500 municipalities in the United States
producing 40 billion gallons of wastewater per day at a taxpayer cost of
$150,000,000 or $55 billion dollars annually. 40 billion gallons per day, or
$14 billion annually, is due to inflow and infiltration (I&I) of ground and
storm water, the cause of which is directly linked to our aging and faulty
sewer infrastructure*. Obviously, if a clever combination of software and
hardware were to be developed that was capable of quickly and inexpensively
recognizing and locating the source of these extraneous flows,
billions of dollars could be saved by communities throughout the world.
The discovery by Eastech’s engineering group of a unique algorithm
designated as “Delta Q” provided the cornerstone for just such a solution.
Once Eastech’s engineers realized that they now had the ability to compute
volumetric differences in wastewater flows between periods of dry and wet
weather and that those differences were exactly identical to the ones
calculated by the globally accepted Manning’s Equation (except without
the requirement for confined space entry in order to ascertain pipe slopes
and coefficients of roughness), an entirely new methodology for reducing
wastewater treatment costs began to evolve.

iTracker ® I&I Detection Monitors are strategically placed within designated
manholes of each Sub-System (major basin) comprising the overall collection
system. An onboard data logger records the differences in wastewater
levels between specified periods of dry and combined dry and wet
weather. An internal flash card within each iTracker stores the pertinent
information for easy transfer to a PC running CostView’s analysis software.
The CostView software program initiates both a volumetric and cost
analysis report of the effects of any extraneous flows that have entered the
Sub-System during the designated monitoring period. Once the Sub-
Systems contributing the highest rate of inflow and infiltration are revealed,
the iTrackers are removed and repositioned (again without the need for
confined space entry) in order to detect and locate those segments within
each Sub-System contributing to the majority of unwanted ground and
storm water.

Performance Mapping the Wastewater Collection Grid
Since both the EPA and the American Water Works Association suggest a “Systems Approach”
for locating major sources of inflow and infiltration (I&I), Eastech’s Engineering Group decided to
follow this identical approach. Wastewater collection systems selected for investigation are
initially divided into separate Sub-Systems (major basins) and then again into Mini-Systems in
order to cost-effectively ascertain the most prevalent areas of unwanted ingress.
I&I Location, Volume and Cost Analysis
Extensive international studies of inflow and infiltration have proven in case after case that the
80/20 Principle usually applies (approximately 20% of the wastewater infrastructure network
contributes 80% of the I&I). These extensive studies only confirm the economic value of
implementing a structured Performance Mapping approach.
Initially, a portable iTracker I&I Detection Monitor is placed at the base of each major Sub-System
within the overall collection grid. iTracker level monitoring is conducted for a minimum period of
five consecutive dry days in order to establish a “dry weather” baseline for calculating a pattern
of diurnal flows completely absent of I&I. The identical procedure is then repeated for a period of
three consecutive months of combined dry and wet weather. Once the collected data is gathered
and transferred through flash card technology to CostView’s Analysis Program, Delta Q algorithms
categorize by volume and cost the extent of I&I effecting each major Sub-System.
Municipal managers are now capable of initiating the process of pinpointing the probable
20% of the collection grid contributing the major portions of inflow and infiltration.

REPORT 2
If only 50% of the I&I discovered in
Sub-Systems 1 and 7 is eliminated, a
municipality will realize annual savings
of $83,000, or $830,000 over a ten year
period. By eliminating the same percentage
of I&I generated by all 8 Sub-
Systems, taxpayers will see a decrease in
their wastewater treatment charges of
$1,545,000 over the same ten year period.

REPORT 4
Further isolation of I&I on a 10 Mini-
System basis is now separately
conducted for each of the major Sub-
Systems (1&7) having contributed the
highest percentages of extraneous flow
as identified by Reports 1 & 2. Repeating
the identical procedure as previously
employed within each major Sub-System,
iTrackers continuously monitor both dry
and dry/wet day wastewater levels within
each 10 manhole Mini-System. Since the
goal has been set to initially eliminate only
50% of the total I&I within Sub-System 1
(50% of $74,000), then according to
Report 4, the volume in question is
located somewhere between manhole 30
and 50 (Mini-Systems D&E). Prior to
instituting camera surveillance equipment,
the investigation can now be narrowed
down even further by repeating the above
process for Mini-Systems D&E.

Using survey data from local records and the EPA, USGS and the AWWA, one can quickly ascertain the number of
homes being serviced by each Sub-System, the average number of individuals per household within that Sub-System,
the daily water usage per average household (the EPA, USGS and AWWA have all confirmed that average daily water
usage by an individual in the United States is 70 Gal/Day) and the municipality’s wastewater treatment rate per 1000
gallons. Once these figures are imported into the CostView software program, reports are generated describing each
Sub-System by actual increases in volume and cost due to inflow and infiltration.
