Accurate flow data is essential for making informed decisions regarding the effective management of collection systems, preventing sanitary sewer overflows (SSOs), and maintaining compliance with regulations.

Traditionally, utilities responsible for operating and maintaining pump stations have relied on periodic site visits to inspect and record flow data. However, contemporary monitoring and alarm systems, offered at economical pricing, have substantially reduced the necessity for these physical site visits. These advanced systems are equipped to autonomously capture and transmit flow rates and other pertinent information to operations personnel.

The OmniSite monitoring units empower operators and collection system managers with accurate and reliable flow data. This capability enables them to make well-informed flow management decisions without the need for frequent visits to each pumping station.

OmniSite provides accurate and reliable flow data by one or both of the following methods:

Volumetric Flow Readings

The OmniSite calculates influent flow and pumped flow data using volumetric flow calculations and uploads it to the GuardDog website. Volumetric flow data can be provided without the need for expensive flow meters.

The volumetric flow data is very accurate under most flow conditions; however, they are less accurate in the following situations:

• When the inflow rate exceeds the pumping rate of one pump
• When the inflow rate into the wet well has sudden variations, such as when there is a pump station upstream of the wet well
• For pumps that use variable speed drives (VFD)
• With long ramp-up/down times when using RVSS “soft start” motor starters

Due to these limitations, the OmniSite volumetric flow calculations are very useful for monitoring the condition of the pumps. However, they are not recommended when accurate flow metering is required or for billing purposes.

Flow Meter Readings

The OmniSite records flow data from flow meters and uploads the data to the GuardDog website. Flow data from flow meters is collected and transmitted via cellular technology and viewed on the OmniSite GuardDog website or smartphone. The website organizes the flow data from the flow meters in charts and graphs and allows the operators to review the data to identify any issues at a site. If there is an anomaly, operations personnel are dispatched to inspect the site and equipment.

Save Time and Money

OmniSite cloud-based cellular monitoring systems save time and money utility managers valuable operating data and providing alarm notifications for operations personnel.

OmniSite cloud-based monitoring systems are the most effective way to monitor pumping stations, improve system efficiency, and reduce O&M costs.
