This article considers the latest developments in constant pressure technology. Constant pressure technology allows operators to manage variations in demand and flow which means they achieve the right flow at the right time, and benefit from considerable costs savings, in terms of energy used and the service life of their pumping equipment. Some systems offer energy savings as high as 40% and aim to double the life of the pumping equipment.
Ian Rowles from Geoquip Water Solutions discusses best practice when working in environments that require special execution pumps. Effective pump management requires the efficient collection, extraction, pumping and disposal of water and wastewater. In special applications the importance of continuous pumping can make the pump selection an essential part of the process. Ian considers pump selection in a range of environments including remediation projects where the ground is contaminated and projects where the environment is potentially hazardous, chemically reactive or difficult.
Landslide activity and slope failure at ‘the Undercliff’ has been an ongoing problem for hundreds of years, promoted by marine erosion at the bottom of the sea cliffs, the geology of the area, high rainfall and high ground water levels. A significant landslide during the particularly bad winter of 1994-5 had seriously affected an area up to 400 metres inland from the coast and it was acknowledged that the instability at Castlehaven would have to be addressed to reduce the risk to public safety, property and the local infrastructure...
This article considers the importance of water supply systems in civil engineering schemes. Groundwater wells are common to many civil engineering schemes and their operational performance can play a crucial role in the successful delivery of a project, whether used for construction dewatering, alternative water supplies for facilities or other applications. Whatever the application, well performance needs to be optimised to achieve high levels of operational efficiency and service availability.
Groundwater wells are common to many civil engineering schemes and their operational performance can play a crucial role in the successful delivery of a project, whether used for construction dewatering, alternative water supplies for facilities or any other application. This article considers the impact of mineral contamination in groundwater wells on operational performance and how the implementation of a regular maintenance programme incorporating BoreSaver can make a significant difference.
