Project Manager - Data Center Water Treatment

Chem Treat is seeking a Project Manager to manage its water treatment scope for the PHX
13 data center project. Working with district leadership, technical specialists, field personnel, and the construction team, this position coordinates the work from preconstruction planning and procurement through field execution, commissioning support, and final turnover.

The work includes mechanical system flushing, chemical cleaning, passivation, deionized (DI) water production and filling, temporary pumping and filtration, water quality monitoring, and glycol filling for designated systems. The successful candidate combines practical mechanical knowledge with strong scheduling, cost control, documentation, and contractor coordination skills, including the ability to coordinate multiple work areas concurrently. Execution follows approved technical procedures, defined contractual responsibilities, and required project acceptance approvals.

Key Responsibilities Project planning and contractor coordination
· Develop and maintain execution plans, milestone schedules, short-term look-ahead schedules, resource plans, and readiness checklists for mobilization, treatment, testing, final fill, and turnover.
· Review contracts, mechanical drawings, piping and instrumentation diagrams (P&IDs), specifications, equipment submittals, and approved procedures to identify system boundaries, scope gaps, dependencies, and required approvals.
· Coordinate with the mechanical contractor, general contractor, owner and commissioning representatives, Chem Treat personnel, and equipment providers. Lead job walks and coordination meetings; track action items, decisions, access needs, and trade conflicts.
· Coordinate concurrent work across data halls or system segments while maintaining separate scope, cost, equipment, and acceptance records for distinct contracts and for water and glycol systems.

Technical execution and system readiness
· Coordinate approved flushing, chemical cleaning, passivation, neutralization, rinsing, DI filling, and startup activities. Coordinate glycol receipt, handling, quality checks, and final fill for systems that require glycol.
· Work with technical specialists and equipment providers to review required flow, pump duty, system head loss, filtration capacity, component pressure ratings, and temporary hose and piping arrangements against approved project requirements.
· Confirm readiness of system isolation, temporary connections, sampling points, utilities, and equipment interfaces before each work phase. Coordinate protection of sensitive equipment and compliance with manufacturer requirements.
· Review field flow, pressure, filter differential pressure, and water quality records to identify deviations, operating constraints, or equipment service needs; coordinate corrective action with the responsible technical and field personnel.
· Track approved chemical requirements, equipment compatibility, treatment durations, and release points. Escalate specification conflicts and obtain required technical approval before changes to treatment methods, equipment, or acceptance criteria.

Procurement, equipment, and site logistics
· Coordinate vendor quotations, scope comparisons, technical submittals, purchase requisitions, and delivery commitments. Support requests for proposal (RFPs), estimating, and proposal development for assigned work or project changes.
· Plan delivery, offloading, placement, rental periods, servicing, and demobilization of temporary pumps, filters, DI equipment, storage tanks, hoses, instrumentation, chemicals, and other assigned equipment.
· Match DI water supply, storage, chemical deliveries, filtration support, and vendor service availability to the execution schedule. Track long-lead…
