When installing a ground water pump station in conjunction with a cavity membrane system it is important that the ground water inflow, and in turn the frequency of pump operation, are monitored.
An increase in pump operation reduces the life expectancy of the pump equipment and leaves the basement at risk.
The ground water inflow will vary subject to weather conditions and construction type therefore it is important that the frequency of pump operation is monitored throughout the construction works and thereafter. This can be achieved via the use of a monitoring device such as the Edincare PowerSafe which has the facility to record the number of pump/s activations and hours run, providing useful information to better understand the pump equipment usage.
As well as monitoring the operation frequency the PowerSafe system offers various functions that may be essential in running and maintaining a pumping station. As well as local high level and pump tripped alarms, the PowerSafe also contains connections to transmit these fault signals to a BMS or similar. Telemetric alerts are available via GSM for complete peace of mind. The duty pump can also be alternated with each activation of the system, further extending the life span of the pumps. Furthermore the PowerSafe comes standard with battery backup in case of a mains power failure, this is available with 1, 2, 3 or 4 hours life span.
In some cases there is an accepted higher than usual inflow of ground water to a pump system, for instance in high water table areas. When such a factor is known at design stage it is important to consider increasing the capacity of the holding chamber as this will reduce the frequency of pump operation. It may also be required to install pumps with a higher output flow rate to match the increased inflow.
With a high frequency of pump operation it is advised that the servicing intervals be increased ensuring that the system stay fully operational at all times and any early signs of wear are reported and appropriate works are undertaken. After installation the frequency of operation should be monitored and any increases advised to your servicing partner who can then recommend more regular servicing where appropriate.
