WaterWorks

The WaterWorks package encompasses the station and pump motor control of any clean or waste water pumping application, including lift stations, storm stations, booster stations, reservoirs and others. A supplementary piece of the StaRTU Configuration software, it allows those with zero programming skills to quickly and easily configure a site, and to replicate that configuration (with slight to drastic modifications) for every other site in a water system.

 

Station / Site Configuration

  • Station type
  • Number of pumps
  • Level source
  • Pump sequencing / alternation
  • Timing parameters
  • Station setpoint for pump control
  • Define output control

 

Pump Configuration

  • Run indication
  • Auto / Not in Auto indication
  • Fault(s) indication
  • Support for check valve
  • Supports VFD
  • Speed
  • Maximum runtime for motor protection
  • Pump cool-down time

Not only does the WaterWorks package allow the user to quickly configure and commission a pump site, it also includes an abundance of common and some not-so-common, rungs of logic to accomplish monitoring and control functionality typical to lift stations, and other pumping applications.

 

Benefits & Features

Pump Control – The WaterWorks package includes basic to advanced pump control, and it provides pump alternation patterns easily selected by the operator. Various pump alternation scenarios include:

  • Runtime equalization
  • Starts equalization
  • Fixed percentage
  • Emergency modes
  • Power efficiency equalization

Start/Stop HOA monitoring and control of all pumps (supports up to 4 at one site)

Pump Statistics include multi-period starts/runtime counters (minutes, hours, daily, weekly, monthly, and annually)

Programmed support for Modbus slave devices – full support of almost any 3rd party devices (power analyzer, pump protection devices, VFDs, etc.). This can include but is not limited to monitoring of pump motor amperage, voltage, temperature and any other relevant information that may be provided by a 3rd party device.

 

Typical data provided for pump motor protection:

Protection (these can be configured to shut off pump)

  • Thermal overload
  • Phase imbalance and phase failure
  • Thermal motor protection via PTC probes
  • Phase reversal
  • Ground fault detection
  • Long starting times and motor stalling
  • Automatic load shedding and restarting
  • Load fluctuations (current, voltage, power)
  • Variations of Cos ϕ (power factor)

Metering:

  • Current on the 3 phases
  • Voltage on the 3 phases (shedding)
  • Motor temperature
  • Ground fault sensing
  • Average current
  • Frequency
  • Power factor, power, power consumption

 

Additional Highlights:

Monitoring and control of the storage tank, wet well, and other level requirements

Level Rate of Change – daily peak time highs with time stamp

Monitoring and control of output and input pressures and flows

Pressure Management System – flexible customized software for Motorola RTUs, enabling RTUs to communicate real-time system pressure data among each other, and manage it via site-specific set points and commands.

Pumping / Flow Averaging and Sampling – Calculate an average of the flow from the main pump station that pumps into the plant in order to help smooth out the high and low peaks.

Monthly Flow Totals from RTUs – Compute Monthly flow totals in the RTUs

Master / Satellite Control – This involves peer-to-peer communication (ability for Master station to slow/stop inflow from satellites stations directly – NOT via the SCADA)

Programmed support for local HMIs
