The Company
Our client is an award-winning specialist in proprietary water and wastewater treatment technologies, delivering cost-efficient, environmentally-driven solutions across industrial and municipal markets. With best-in-class systems deployed at over 100 sites globally and strong year-on-year growth, this is a business with real momentum — and a pipeline to match.
The Role
We're looking for an experienced Mechanical Site Manager to take ownership of mechanical installation and commissioning activities on water and wastewater treatment projects across the Birmingham area.
With a genuine hybrid arrangement in place (3 days on site, 2 from home), this suits a self-motivated site professional who can manage their workload effectively both on and off site. You'll be the central point of contact between site teams, subcontractors, and the wider project management function — keeping works on programme, on budget, and to the quality standards this client's reputation demands.
What We're Looking For
Proven experience as a Mechanical Site Manager on water sector, process, or industrial projects
Strong working knowledge of mechanical pipework, pumping systems, and associated plant — ideally within a treatment works environment
SMSTS, CSCS (Black or Gold Card), and First Aid certification
Familiarity with NEC contracts or similar
Strong communicator, comfortable managing multiple stakeholders and representing the business professionally on site
What You'll Be Doing
Managing day-to-day mechanical installation activities on water and wastewater treatment schemes
Coordinating subcontractors, suppliers, and direct labour to maintain programme and quality
Ensuring full compliance with CDM regulations, site H&S requirements, and environmental obligations
Liaising with the client, design team, and commissioning engineers throughout the construction phase
Producing and maintaining RAMS, site diaries, progress reports, and O&M documentation
Supporting the commissioning phase alongside process and commissioning engineers to bring plant into operation
Managing RFIs, technical queries, and variation events as they arise
What's on Offer
Competitive salary (dependent on experience)
Hybrid working — 3 days site, 2 from home
Technically varied, high-impact water infrastructure projects
A growing business with a strong forward pipeline and a genuine reputation for sector innovation
