Water companies are almost unique in their ability to choose when they use energy. This can be achieved through the careful interaction between pumping and water storage. Aquadapt software takes full advantage of this characteristic to minimize energy costs by optimizing valve and pump schedules.
Reducing energy costs through smarter scheduling
The Aquadapt software targets energy cost reduction in five ways:
- By moving energy consumption to cheaper tariff bands
- By reducing peak demand charges
- By running pumps more efficiently
- By choosing the shortest path from source to destination
- By choosing the lowest cost source of water (raw and treated).
Moving energy consumption in time
Energy companies typically charge more for energy consumption when demand is high. The Aquadapt system schedules pumps and flows into lower cost energy periods while still satisfying storage and pressure requirements.
Reducing peak demand charges
A peak demand charge is a penalty fee imposed by energy companies for the highest electrical load recorded in a month. Aquadapt software helps companies avoid peak demand charges by choosing the minimum number of pumps required to run concurrently.
Improving pumping efficiency
Pumps are designed to run most efficiently at a particular pressure and flow rate. Aquadapt software is able to resolve multiple complex hydraulic equations and establish the most efficient time to run and combination of pumps needed to meet demand. This enables pumps to run closer to their peak efficiency using less electricity to pump the same volume of water.
Selecting the lowest cost source or path
As water transmission and distribution systems evolve over many years there are often a variety of ways water can get to a customer. Often more than one treatment plant can service the same customer providing back-up for planned and unplanned outages. Aquadapt software can solve the very complex cost calculations in real-time to select the lowest costs source of water, which may vary during the day, and the lowest cost path to get water to a storage tank or customer.
How it works
Live data collection from the SCADA system is used by the Aquadapt system to predict future water consumption. Aquadapt software excels in picking up changes in demand quickly and accurately and can handle noisy or poor quality data, providing maximum reliability. Choosing the lowest cost solution without sacrificing reliability or safety, production of treated water is directed to the cheapest sources of water, while pumping is moved to the lowest cost tariff periods. Where possible, the storage capacity of reservoirs is used to satisfy demand during expensive electricity periods. This enables peak tariff windows to be avoided, where possible, by using the storage capacity of reservoirs to satisfy demand. Aquadapt software also reacts quickly and accurately to sudden changes in demand such as fire fighting draw-off.
Aquadapt software is unique in its ability to predict future operations for the next 48 hours, enabling operators to fix problems before they occur. It allows them to test operational changes and analyse the consequences without affecting the live system.
Our team of engineers and technical specialists with experience in water treatment, hydraulic modelling and optimization techniques has developed this award winning software with flexibility in mind.
- Operates at its best in the real time electricity markets
- Maintenance can be scheduled within Aquadapt software at the most cost effective times
- Each plant and pump can be manually scheduled on or off for any number of half-hour time units, or left in automatic or any combination of the two modes
- Plant production rate limits can be changed at any time, with a new solution generated in minutes
- Each reservoir and pumping plant can be included or excluded from automatic scheduling at any time.
Aquadapt software can be used with gravity systems, pumped systems and well fields, or any combination of these sources.
The Aquadapt system uses a library of customized components to reduce design risk and they have been field proven to control plant and equipment safely and reliably. Using these proven components reduces customization time and increases flexibility. Changes to plant design can be incorporated adding components to the Aquadapt database. Components can be added or reconfigured at any time to adapt to expansions in the system. Aquadapt software can grow as your company grows.
Security is built into all levels of control and communication to reduce risk from the Aquadapt servers' right through to the field. Alarms can be directed through existing alarm systems to alert the operator to any problems or potential problems.
Aquadapt software can detect pipe and reservoir leaks and indicate unusual demand patterns to an operator long before they become evident by any other means. Reservoir maximum and minimum levels are protected, reducing the risk of overflow or insufficient water supply at critical times.
Where demand cannot be met, the Aquadapt system can predict the shortfall and calculate expected reservoir levels. Aquadapt software can be turned on and off at any time, allowing the control system to resume its original control strategy.
Water quality improvements
Aquadapt software's ability to increase water turnover, utilize available storage and to apply measures such as deep cycling notably improves water quality. Aquadapt software can be configured to smooth flows through the system enabling more consistency when treating water and decreasing water aging. The Aquadapt system can meet the most rigorous water quality policies, while still using the lowest cost source of water.
Consistency of operations and water delivery
Having an automated system brings consistency and reliability to operations. Aquadapt software enables operators and engineers to know 48 hours ahead what the system is going to do, with pumping schedules that are constantly being updated with real time data from the field. The Aquadapt system can be relied upon to find the best pumping schedule within operational and programmed constraints creating consistency of water delivery and daily operations.
