Boosted Cold Water Systems
Where mains water pressure is insufficient to serve multi-storey or high-demand buildings, MPM Mechanical Services designs and installs boosted cold water systems that deliver reliable, regulated water supply to every floor and outlet.
We work across the full range of building types — from high-rise residential towers and mixed-use developments to commercial office fit-outs and healthcare facilities — specifying and installing the right solution for each project’s pressure requirements, occupancy profile, and building regulations.
Our scope typically includes:
- Cold water booster pump set supply and installation (duty/standby configurations)
- Break tank installation and cold water storage vessels
- Distribution pipework from plant room to risers and final connections
- Pressurisation unit installation and commissioning
- BMS integration and remote monitoring capability
- System commissioning, flushing, and disinfection
- WRAS-compliant installations and RPZ valve incorporation where required
- Compliance with Water Supply (Water Fittings) Regulations and L8 Legionella guidance
Why it matters:
In tall residential and commercial buildings, an undersized or poorly designed cold water strategy leads to pressure drop complaints, flow imbalance, and legionella risk. MPM’s installations are designed from the outset to meet peak demand conditions, with duty/standby pump arrangements ensuring continuity of supply and BMS connectivity enabling proactive fault detection.
Our experience across landmark London schemes — including high-rise residential developments and large-scale commercial fit-outs — means we understand the coordination demands of cold water installations alongside other M&E services, delivering to programme without compromise on quality.
Frequently Ask Question
Mechanical building services refers to the systems that keep a building comfortable, functional, and safe — including heating, cooling, plumbing, drainage, ventilation, and water services. MPM manages the full mechanical scope on construction projects: from below-ground drainage and cold water mains through to plant room installations, pipework distribution, and final fix connections to all mechanical equipment.
MPM works across a wide range of project scales — from single-building commercial fit-outs to large, multi-phase development programmes. Our portfolio includes high-profile schemes such as Apple EU HQ at Battersea Power Station, The Chancery Rosewood Hotel, and AstraZeneca Pharmaceutical, as well as smaller commercial and residential contracts. Whatever the scale, we bring the same level of precision and professionalism to every project.
Effective trade coordination is central to how MPM operates. We work from coordinated MEP drawings and attend regular design and progress meetings to ensure our mechanical installation integrates seamlessly with structural, electrical, and ventilation works. Our engineers are experienced working within multidisciplinary teams and take a proactive approach to resolving clashes and maintaining programme.
