Water Pumping Systems
Water Pumping Systems
The resource of water is critical for life. Time and / or Event based management of the resource is always a critical but routine affair. Monitoring of various parameters to achieve the targets of water supply make it imperative to have a real time water pumping management solution.
Monitoring of various parameters in the system on a “real time” basis and a benchmarked water supply system is what RDS is capable of delivering on time every time.
Sub System I : Level Measurement
In any pumping system the primary parameter to be monitored online is water level at the source i.e. river bed etc.
In raw water pumping systems the level at the pumping system is also required to be communicated to the dam / irrigation authorities for better coordination.
Scope of Automation:
- Measurement of online level of water, decision making as per logic and control action
Sub System II : Supply Conditions Verification
The monitoring of the supply conditions would essentially ensure that the pumping systems are operated only in the specified variation ranges.
Scope of Automation:
- Monitoring of supply conditions, decision making as per logic and control action
Sub System III : Pump Operation
The pumping systems would involve the process of priming / air release as the case may be. On completion of priming the pump/s need to be started.
The pressure at the delivery of the pumps is required to be monitored continuously for preventing any air locking or drop in pressure.
Scope of Automation:
- Priming to be carried out if needed
- Start and Stop of Pump/s
- Monitoring of pressure condition at the delivery of the pump
- Ensuring equal duty cycle of all pumps
- Decision making as per logic and control action
Sub System IV : Valve Operation
a. Valves at the delivery of the pump :
Valves at the delivery of the pump are normally maintained in the closed condition till the pump is able to reach a preset pressure point.
On reaching the same the valve will be opened. The reverse process would be followed during shut down.
b. Valves at the distribution header :
The valves at the distribution header if any are operated as per the feedback of various tanks / treatment plants or on basis of timing or both as the case may be.
Scope of Automation:
- Operation of Valves with electrical actuators with feedback to control system, decision making as per logic and control action
b. Valves at the distribution header :
The valves at the distribution header if any are operated as per the feedback of various tanks / treatment plants or on basis of timing or both as the case may be.
Scope of Automation:
- Operation of Valves with electrical actuators with feedback to control system, decision making as per logic and control action
Sub System V : Booster Pumping System
The system may include Booster Pumping Stations with or without MBRs, in case of very large pumping distances from the source.
In such a case the same sequence as that for the raw water pumping system is followed along with the operation of the raw water pumping station itself
b. Valves at the distribution header :
The valves at the distribution header if any are operated as per the feedback of various tanks / treatment plants or on basis of timing or both as the case may be.
Scope of Automation:
- Operation of Pumps and Valves with feedback to control system, decision making as per logic and control action
Sub System VI : Communication
The above sub systems need to be linked with each other for a fully effective system operation. This is achievable using cabling for those subsystems that are located within the pump house or nearby the pump house.
Those sub systems however where cabling would represent a cost or physical issue a choice has to be made to select a wireless communication option as per the site conditions
Scope of Automation:
- Provision of suitable wired / wireless communication system as per site requirements and conditions, decision making as per logic and control action
Sub System VII : Monitoring & Data Logging
The entire system from source to the delivery point needs to be monitored / controlled from one single location which may be local / remote situated.
Scope of Automation:
- Provision of suitable SCADA (software) with programming as per site requirements and conditions, decision making as per logic and control action
