Newport Bloors – Temporary Pond Isolation for Outfall Installation

Newport Bloors – Temporary Pond Isolation for Outfall Installation

Project Overview

Installing a new outfall pipe, headwall and debris screen within an existing pond required temporary water control to provide suitable conditions for construction. The works were confined to one corner of the pond, making full dewatering unnecessary.

A localised isolation arrangement was required to establish a dry working area around the proposed installation zone, allowing construction to proceed without extending the temporary works across the entire water body.

High Water Solution

High Water supplied and installed a three-sided arrangement of Geodesign Temporary Works Barriers to isolate the required section of the pond.

The modular barrier system was configured around the corner of the pond, creating a defined area of isolation to provide access for the installation works. The three-sided arrangement offered a targeted approach to water control, using a configuration suited to the existing pond layout and the extent of the construction area.

By isolating only the section required for the works, the arrangement avoided the need to dewater the entire pond, providing a practical solution for carrying out drainage infrastructure installations within an existing water body.

The three-sided Geodesign Barrier arrangement provided a localised working area for the installation of the new outfall pipe, headwall and debris screen.

The solution demonstrates how modular temporary dam systems can be adapted to suit contained water bodies as well as traditional river and canal environments. By configuring the barriers around the specific requirements of a project, targeted isolation can provide access for construction and maintenance works without unnecessarily disturbing the wider water body.
