By having the ability to deliver over 40 times the detection capability of portable-type flow

3 INFLOW & INFILTRATION MICRO DETECTION In case after case, extensive studies have proven that 80% of I&I originates in just 20% of the collection system. By having the ability to deliver over 40 times the detection capability of portable-type flow meters, patented itracking technology provides the means to locate and pinpoint inflow and infiltration to within a single pair of adjacent manholes. 3

4 INFLOW & INFILTRATION MICRO DETECTION Advanced TECHNOLOGY Currently available methods for locating I&I, such as portable flow meters, are expensive, time-consuming to install, difficult to maintain, and technologically inefficient due to their 2-4 mile upstream piping requirement for accurately ascertaining flow. Alternative methods, such as Nighttime Flow Isolation, require expensive and time-consuming confined space entries while only providing a snapshot of true system performance. Considering the above, it was time for a more technologically advanced and cost-efficient solution capable of pinpointing the sources of I&I down to micro-basins comprised of just a few manholes. itracker Wi-Fi Enabled Sensors itracking is the patented integration of three advanced technologies; low-cost sensors, wireless connectivity and high-speed automated software. State-of-the-art itracker sensors operating on preset time schedules continuously track collection system performance by measuring and recording volumetric changes in wastewater levels between dry day and wet weather events. Upon downloading of logged data to a laptop or PC running itracking automated software, uniquely developed algorithms convert each volumetric change to its corresponding value in gallons per minute. 250 Feet Non-Contact Sensor Weight: 1.9 lbs Dual Lithium Batteries Wi-Fi or Cellular Enabled Integrated Data Logger 4

5 Advanced PERFORMANCE itracker Sensors were engineered with only one thing in mind; to provide inexpensive, quick and safe access to collection system performance data. Cost is 1/3 that of conventional flow meters; Installation is 15 minutes ; Maintenance is Zero ; Data retrieval is Safe ; Software is Free. $ Minimal Projects Costs When comparing historical purchase and installed costs of conventional doppler-type portable flow meters to itracker Sensors, savings of anywhere from 60% to 80% can be immediately realized. Non-confined Space Installation The true cost of any sewer study lies in the ongoing expense of confined-space entry, repetitive maintenance and time-consuming data retrieval. Non-confined space itracker installation is accomplished in 15 minutes. Zero Maintenance With above-the-flow itracker technology, the sensor never comes into direct contact with the media being measured. Repetitive maintenance due to fouled sensors, along with loss of critical data is no longer an issue. Remote Data Retrieval Conventional flow meters require physical retrieval of data, which at times, needs to be performed under non-accomodating conditions. Wi-Fi enabled itrackers allow for remote data retrieval with any Wi-Fi enabled device. Cellular capability is available as an option. 5

6 INFLOW & INFILTRATION MICRO DETECTION MICRO I&I DETECTION Zeroing in on the problem Since 80% of I&I is contributed by 20% of the system, then pinpointing its cause to within adjacently located manholes is the key to a successful Sanitary Sewer Evaluation Study. When compared to portable flow meters, itracking technology decreases previously required 2 to 4 mile basin investigation lengths down to a single pair of adjoining manholes. Through a simple 3-step process, itracker Micro Detection Sensors can deliver from 40 to 80 times the I&I detection capability of conventional flow metering systems. 6

17 Pinpointing I&I down to Adjacent Manholes I&I Micro Detection 17

18 I&I Micro Detection itracking Micro Detection is based on a simple premise: What municipalities and utilities are ultimately interested in accomplishing is NOT to measure each gallon of I&I but to quickly and cost-efficiently PINPOINT those areas within the collection network responsible for contributing the greatest influx of rain and groundwater. This is exactly what Eastech s itracking Micro Detection technology is designed to achieve; locate inflow and infiltration down to adjacent manholes simply, safely, quickly and affordably. Hundreds of independent flow studies have confirmed that 80% of I&I resides in just 20% of the collection network. It is in this 20% of the system that I&I needs to be discovered. Conventional Doppler-type flow meters, while able to measure flows in larger basins (2-4 miles) where wastewater levels remain at heights satisfactory for covering their "bottom-sitting sensors, have proven themselves incapable of providing the necessary high resolution monitoring required for micro detecting I&I in the smaller diameter pipes (8"-12") that make up 85% of almost every collection system. This shortcoming presented Eastech with an opportunity for developing a solution not currently possible with conventional flow metering devices. The key to itracking Micro Detection is the seamless integration of low-cost sensors, wireless connectivity and automated analytical software, delivering results where portable flow meters fall short. itracker Wi-Fi and cellular-enabled sensors simply and safely record wastewater levels from 0 100% pipe ID during dry day periods and wet weather events and then convert those changes in level to volumetric differences in flow through the use of uniquely developed algorithms embedded within the itracking software program. With the simple click of a button, bar charts, line graphs and operating performance reports are clearly presented detailing the contribution of I&I for each mini and micro-basin within the area under investigation. In many instances, the problem is pinpointed down to adjacent manholes without the requirement for expensive monitoring equipment, confined-space entry, repetitive maintenance or "in the road" data retrieval. The success or failure of attempts to determine the actual location of I&I does not depend on the length of the sewer evaluation study period but rather on the investigative ability of the detection method employed. With itracking Micro Detection technology, the time period to pinpoint faulty infrastructure could be as short as one rain event. This single storm approach is the biggest factor in delivering a successful and cost saving I&I detection study. 18

19 itracking Micro Detection has the ability to reveal the location of I&I after a single storm event Low-cost itracker sensors provide the high-resolution data points required for pinpointing the 20% of faulty infrastructure contributing the majority of I&I. By strategically placing itracker sensors upstream of regional flow meters, changes in wastewater volume as small as 1/10 can be observed in both mini and micro-basins. How itracking Works itracker Wi-Fi or cellular-enabled sensors simply and safely record wastewater levels from 0 100% pipe ID during dry day periods and wet weather events and then convert those changes in level to volumetric differences in flow through the use of uniquely developed algorithms embedded within the itracking software program. itrackers monitor and record levels within the manhole Maintenance-free itracker sensors are capable of accurately measuring collection system performance on streets with minimal amounts of homes or commercial facilities. itracker sensors are installed from the street level without the need for confined-space entry. Sensor calibration is accomplished in 5 minutes using any Wi-Fi enabled mobile device.
