Gheluvelt Park Splash Pad - Worcester Worcester City Council

Existing Site

The site previously featured a splash pad, a water play area designed for recreation and enjoyment. However, the facility had reached the end of its functional lifespan, necessitating replacement or significant renovation.

Design

The primary objective of the redesign was to modernise and improve the reliability, efficiency, and safety of the splash pad’s water treatment and pumping systems. The existing arrangement, which housed pumps in two underground tanks adjacent to the splash pad, presented ongoing maintenance challenges, particularly during the operating season when pump failures caused significant disruption.

Key Design Achievements:

• Decommissioning of Underground Tanks
  The design included partially breaking into and infilling the two existing underground tanks. One was converted into a prefilter chamber, now functioning as a suction collection chamber.

• New Above-Ground System Configuration
  A variable-speed suction return pump was introduced within a new GRP plant room. This pump dynamically responds to flow demands from the interactive features, maintaining efficient circulation by feeding the dirty side of the new above-ground tank system.

• GRP Plant Room Design
  A new glass-reinforced plastic (GRP) plant room was designed and specified, slightly larger than the previous container to accommodate all key plant components, including:

  • A 1.8m diameter deep bed sand filter with AF glass media (filtration down to 4 microns)

  • Four UV disinfection tubes

  • A stainless-steel manifold for pressurised delivery to features

  • Granudos dosing system with Crystal control unit

  • Multiple above-ground pumps for improved accessibility and safety

• Chemical Dosing Strategy
  The system was designed to eliminate manual handling risks by using granular calcium hypochlorite and sulphuric acid in sealed systems. The Crystal controller samples water from the clean tank, while the Granudos unit doses into the dirty tank for thorough mixing and effective chemical distribution.

• Improved Water Feature Control
  Feature activation is managed by a Dynamic Sequence Controller (DSC), enabling bespoke programming and play sequences tailored with the client.

• Revised Site Layout
  A new layout relocated the plant room and storage container for direct and efficient connections between components, ensuring safe access and future flexibility.

Construction Phase

Following the design phase, we delivered the full construction, installation, and commissioning of the new splash pad plant system, achieving all intended outcomes in safety, serviceability, and operational reliability.

Key Construction Achievements:

• Tank Conversion and Civil Works
  The underground tanks were carefully broken into and partially filled, with one retained as a suction collection chamber. Pipework was realigned and connected to suit the new configuration.

• GRP Plant Room Installation
  The new GRP plant room was installed complete with a plywood internal liner to prevent condensation and protect electrical components. All equipment was fitted, wired, and commissioned as specified.

• Filter and Pump Installation
  The deep bed sand filter and all associated pumps were installed. The system was pressure tested, calibrated, and confirmed fully operational, delivering clean, treated water to the splash pad.

• Pipework Testing and Reconnections
  Existing supply lines were excavated, pressure tested, and retained where suitable. New chambers were constructed to complete connections to the new plant room.

• Chemical Dosing Commissioning
  The Granudos dosing system and Crystal controller were fully set up and calibrated. Safety bunds and containment for sulphuric acid were installed, confirming effective chlorine and pH control with rapid response to varying water conditions.

• Safety Surfacing and Drainage Works
  The old surface was removed, the concrete base prepared, and a new 15mm EPDM wet pour safety surface installed in a natural countryside colour scheme. All drainage runs were inspected, pressure washed, and confirmed clear.

• UV Disinfection and Feature Activation
  UV disinfection units were installed inline ahead of the stainless-steel manifold. The effects pump was commissioned to deliver pressurised, filtered water to the features, maintaining constant pressure for quick activation.

• System Testing and Client Sign-Off
  The DSC controller was programmed and customised on site with the client. The system was tested under operational conditions and handed over successfully.

Project Management & Safety

• A dedicated site compound was established for materials, staff welfare, and secure storage.

• Scheduled deliveries were planned with safety protocols including banksmen to guide vehicles.

• Comprehensive risk assessments ensured public safety, controlled access, PPE compliance, and environmental protection.

• The project team utilised a client portal for real-time updates, images, and communication, ensuring transparency and efficient issue resolution.

By following this methodical approach, the splash pad was successfully delivered as a high-quality, sustainable, and engaging water play area for the local community.

Post-Completion & Safety Inspection

Upon completion, a thorough independent play inspection was carried out to ensure compliance with EN 1176/77 Playground standards and confirm the area was safe for public use.
