Operations & Maintenance

Most plants run worse than they were designed to. Not because anything is broken, but because the daily care — instrument calibration, dose-rate verification, log-reading, the occasional CIP — gets squeezed by other production priorities. Outsourced O&M takes that pressure off you and turns plant performance back into a metric you can rely on.

What this engagement covers

Four pieces of work, run together.

Daily operations
Either resident operators (for larger plants) or scheduled visits (3x/week for smaller ones). Log-reading, dosing pump verification, sample pulls, instrument cross-checks. The unglamorous work that keeps plants from drifting.
Chemistry supply and dosing
Continuous supply of programmed chemistry — antiscalant, biocides, corrosion inhibitor, coagulant. Dosing rates verified weekly against consumption logs. Surprise spikes investigated.
Preventive maintenance
Calendar-based maintenance — pump seals, instrument calibration, valve service, cartridge filter swaps, multimedia backwash optimisation, RO cleaning (CIP) at scheduled intervals or against pressure-drop triggers.
Reporting and analytics
Monthly performance report — KPI deltas vs. target, chemistry consumption, maintenance log, recommendations. Quarterly review with plant management. Year-end optimisation review where we recalibrate the programme to actual operating data.
Engage us when

The signals that point at this service.

  • Plant is critical to production but you don't have specialised water-treatment staff in-house
  • Existing in-house ops team is small and getting overwhelmed during peaks
  • Multiple plants across multiple sites and you want consistent monitoring and reporting
  • ISO 14001 / 50001 audit pressure to formalise plant operations
  • Recurring performance issues that in-house team can't quite resolve
Process

How a typical engagement runs.

01

Baseline audit

Two-week audit to establish the current state. Lab data, instrument check, log review, KPI baseline. Output is a contract scope and pricing.

02

Mobilisation

Operator training (or hiring), procurement of consumables, instrument check-and-calibration, opening of monthly reporting cycle.

03

Steady-state operations

Continuous. Site visits per agreed cadence, monthly reporting, quarterly review.

04

Annual optimisation

Programme recalibration. As feedwater shifts, equipment ages, or operating envelope changes, the programme should adjust. We do this every 12 months minimum.

Pricing

What this typically costs.

Monthly retainer based on plant size, complexity, and visit cadence. Typical small-plant retainer: PKR 180,000 – PKR 350,000/month for visits-based. Resident-operator engagements run PKR 650,000 – PKR 1,200,000/month. Chemistry consumables are billed at-cost-plus-margin, separately from the operations retainer.

Common questions

What buyers ask before signing.

Can I outsource just the chemistry programme without full O&M?

Yes — programme management with monthly site visits and chemistry supply runs about 40-50% of full-O&M cost and is the right entry-level engagement for plants where the operations team is already in place.

What's covered in the monthly retainer vs. extra?

Retainer covers: scheduled site visits, instrument calibration, monthly reporting, on-call phone support during business hours. Extra: emergency call-outs (after hours), chemistry consumables (passed through), major maintenance (CIP chemicals, membrane replacement), training engagements beyond the initial mobilisation.

Do I have to commit to a long contract?

Standard contract is 12 months with 90-day notice. Both sides need 90 days to ramp up or down responsibly — the chemistry supply chain alone has 60-day reorder cycles. We don't lock people in beyond 12 months at a time.

How does AA Solutions O&M compare to a Big Four (Veolia, Suez, Nalco) contract?

Big Four engagements come with extensive global SOPs and multinational liability cover but cost 2-3× our pricing for plants in our scale range, and the engineers on the ground are often local subcontractors anyway. We compete on the engineer talent and the price; we don't compete on the brand power. For some clients (multinational pharma, public-listed industrials) the Big Four name is worth the premium. For most Pakistani industrial clients, ours is the right choice.

What happens if a plant fails on your watch?

Contractually defined SLAs — typically uptime, product-water quality, and recovery — with credit clauses if we miss them. Practically, we have a 2-hour response window and a 4-hour on-site window for critical plants in Karachi (longer elsewhere). Genuine plant failures usually have root causes that pre-date our engagement; we work them through with the client and document.
