Project Overview

The pond at Birchfield Gardens had suffered from poor water circulation and inadequate aeration for generations. Low dissolved oxygen and stagnant conditions had compromised both the ecological health of the pond and its appearance as a public space.

Waterscapes carried out a technical assessment and developed an integrated approach to address both problems. The solution focused on generating consistent movement across the pond body, combined with active aeration to raise oxygen levels and create conditions that support aquatic life over the long term. 

Technical Details

Water Circulation System

The circulation system was designed to draw water from one end of the pond and return it at two points on the opposite side. This cross-flow configuration creates continuous movement across the full width of the water body, preventing stagnation and improving conditions throughout the pond rather than just at the surface or margins.

Aeration & Floating Fountain

To raise dissolved oxygen levels within the water, a floating fountain manufactured by Kasco was installed alongside the circulation system. The fountain actively entrains oxygen into the water column while creating visible movement above the surface — an added point of interest for park visitors and a clear sign that the water is actively managed.

Site Infrastructure

A new steel secure cabinet was installed adjacent to the pond to house the timer controls for the circulation and fountain equipment. The cabinet also provides dedicated on-site storage for maintenance tools, making routine upkeep of the system straightforward and keeping the pond area tidy.

Environmental Enhancements

As part of the wider improvement programme, the client and main contractor created reed beds at each end of the pond. These natural plantings work alongside the improved circulation and aeration to support water quality further, encourage the return of native wildlife, and strengthen the long-term ecological value of the site. 

Results & Outcomes

The works at Birchfield Gardens have significantly improved conditions within the pond. Water is now in continuous circulation, oxygen levels are actively maintained, and the site has the infrastructure in place to support consistent, long-term management. The combination of the circulation system, Kasco fountain, and reed beds has created a more ecologically healthy and visually engaging public space — one that works better for both the local community and the wildlife that depends on it.
