Arundel Lido is run by the Arundel & Downland Community Leisure Trust (ACT), which is a registered charity that does not receive any regular council funding towards running costs. ACT was established to provide leisure facilities for the local Arundel community and visitors to the town and to preserve Lido Heritage in West Sussex. It aims to improve the conditions of life particularly for those who are disadvantaged by reason of their youth, age, disability or social / economic circumstances.
To keep the Lido open for the local community, ACT depends on its volunteer Trustees and donations. Upon hearing a talk by Lido Manager Nikki Richardson at an Arundel & District Rotary Club meeting, Rotarian and water engineer George Rose learned of a leakage issue at the main pool which was costing ACT thousands of pounds in lost water annually. George met with Trustee David May, Operations Director, to discuss how the Rotary Club could help to solve their leakage problem.
The Leak at the Lido
The main pool was constructed in 2002, inside the shell of the original pool. The pipework connecting the pool with the plant room is located in the cavity between the two structures. The leak was known to be coming somewhere from this pipework which unfortunately was not well designed as it is virtually inaccessible from a maintenance perspective. ACT had already spent over £10,000 trying to find the leak – the high cost due to the thick reinforced concrete that had to be broken out to access the cavity and then put back again (not a sustainable course of action).
Cavity Pump System
As a counter measure, David had been using an existing inspection chamber to lower a submersible pump into the cavity and pump it out to recover the leaked water. The benefit of this exercise is that the water can be recovered many times faster than the rate at which it’s being lost. However, it was a painstaking manual task that required an operator to be present, to prevent the pump from running dry or boring itself into the shingle at the bottom (which had happened before, requiring specialist equipment to retrieve the pump).
George designed, specified and commissioned a monitoring and control system to automatically run the pump according to the water level in the cavity. The system consists of a capacitance level probe and local control panel with starter to ensure that the pump can be operated without any risk of damage. The consultation, design and commissioning was provided free of charge, and the cost of the equipment was funded by Arundel & District Rotary Club. The system will save the ACT over £3,000 in annual water costs.
