MANTRA Time of Day Pumping (MANTRA TDP) minimizes power costs for pumping
water into distribution networks and reservoirs while maintaining water
level and water discharge pressure constraints.
MANTRA TDP (patent pending) optimizes and schedules pumping activity
to minimize total utility cost while assuring adequate water supply for
demand and safety requirements. Previous studies indicate that off-peak
pumping reduces the power costs for water transmission and distribution
by 25% to 60% over demand based pumping schedules.
Time of Day Pumping takes advantage of water storage capacity to schedule
water supply pumping to time periods with the lowest power cost while
smoothing water movement requirements to reduce peak power demand surcharges.
MANTRA TDP monitors tank levels and usage rates on-line and optimizes
pump schedules every 15-30 minutes. Sudden demand changes, such as a
drawdown due to a fire, are quickly identified and new pumping schedules
implemented to accommodate the new demand minimizing costs, while maintaining
adequate pressures and safety requirements.
What differentiates MANTRA
TDP from other pump schedulers is that MANTRA
TDP is a dynamic optimizer
which is simple to configure and flexible to address varying system configurations.
TDP is a set of function blocks within our established MANTRA
advanced process control system software. The solution is built using
modular function blocks through an easy-to-use graphical configurator.
Maintenance and modifications are easily implemented by the user.
MANTRA is applied as supervisory control over the existing SCADA or
control system using our suite of standard interfaces. The complete library
of control functions and logic are available to allow incorporating other
advanced control solutions, such as chemical injection optimization,
advanced alarming and system diagnostics. Faceplates, also selected from
the built-in library, can be used standalone or embedded in the existing
Human Machine Interface (HMI).
MANTRA TDP Module Capabilities

Reduce the power costs for water transmission and distribution
by 25% to 60%.
Send ControlSoft a typical monthly invoice of power
costs and rate schedule for the water and transmission network.
We will calculate the theoretical maximum savings and estimate
an achievable savings based on using our dynamic optimizer. If
the savings are significant, we can arrange a trial installation
of our software to prove the savings potential.
