Ocmis carried out the detailed M&E design, supply, and Installation of the Water Feature and Landscape Irrigation at Harbour Central in the Isle of Dogs London.
This cascade water feature has been installed in the garden square at the new Galliard Homes Harbour Central development in London’s Docklands, and perfectly sets the mood for tranquillity and reflection. The sound of the falling water in the background is relaxing for residents while they enjoy the garden space.
The feature is a cascade of water, which overspills over the castellated weir edge on two sides from the top pool to a lower pool. In the basement plantroom, the water is recirculated from the lower pool and is passed through a sand filter to filter out any dirt, and an automatic disinfection dosing system to remove any microorganisms that may develop into algae. The treated water is then returned to the upper pool in a way that leaves the surface calm and in contrast to the lower pool.
To ensure that the garden planting receives sufficient water to thrive, three separate methods of irrigation is used. Pop-up sprinklers automatically controlled by solenoid valves are used for the turf areas, spraying 4mm per square metre, per night. Drip irrigation has been laid in the beds at 330mm spacings for the shrubs, emitting 4mm of water per square metre, per night. Drip necklaces are used around the trees. The Rain Bird ESP-LXD controller, in conjunction with soil moisture sensors, efficiently schedules the required water for all the plants, trees and turf growth depending on the rate of rainfall etc.
