How much does an ETP cost?

It depends on flow, inlet strength and the outlet required. A simple physico-chemical plant for low-strength effluent costs a fraction of a high-COD pharma ETP with anaerobic, aerobic and ZLD stages. Send your inlet analysis and flow — we give a budget range within one working day.

How much space does an ETP need?

Roughly 1–2.5 m² per KLD for a conventional plant, less for MBR or packaged units. Anaerobic and ZLD stages add area. We give a footprint with every preliminary scheme.

What are the discharge norms for industrial effluent in India?

General standards under the Environment (Protection) Rules: pH 5.5–9, BOD ≤ 30 mg/L, COD ≤ 250 mg/L, TSS ≤ 100 mg/L, oil & grease ≤ 10 mg/L, with industry-specific limits for parameters such as colour, phenol, ammonia, chromium and TDS. Your consent to operate from the State Pollution Control Board states the exact limits that apply.

Can treated effluent be reused in the plant?

Yes — after tertiary filtration and, where needed, UF and RO, treated effluent is commonly reused for cooling towers, floor washing, gardening and, in many plants, process make-up. Reuse reduces fresh-water cost and is mandatory in ZLD areas.

How long does it take to build an ETP?

A packaged skid for small capacity: 8–12 weeks. A site-built turnkey plant of a few hundred KLD: 5–8 months including civil work, followed by 4–8 weeks of biological seeding and stabilisation.

Operation & Maintenance Contracts

A treatment plant is only as good as the shift that runs it. We operate plants to their design outlet — with the people, chemicals, testing and paperwork that compliance needs. Also offered as an annual maintenance contract (AMC) for STPs and ETPs anywhere in India.

What an O&M contract from KEE covers

Most treatment plants in India underperform not because of design but because of operation: an untrained operator, chemicals dosed by guesswork, sludge never removed, a blower running with a torn diaphragm for six months. Our O&M contracts put an engineer behind the plant — trained operators on shift, a process engineer reviewing data weekly, chemicals supplied and optimised, and every result documented for the Pollution Control Board.

We operate plants we built and plants we did not. A takeover begins with a condition audit and a stabilisation period, after which we commit to outlet performance.

Scope options

Comprehensive O&M: Manpower (operators, supervisor, chemist as required), all chemicals, consumables, routine and preventive maintenance, lab testing, compliance reporting and performance guarantee. One monthly invoice, one accountable party.
Operation only: Trained manpower and process supervision; client procures chemicals and spares to our specification.
Annual maintenance contract (AMC): Scheduled preventive maintenance visits, breakdown response, spares management for RO, DM, dosing and mechanical equipment.
Remote monitoring and supervision: Online instruments with cloud dashboard; our engineer reviews trends and directs the client's operators — for small plants and remote sites.
Troubleshooting and revival: Short engagements to bring a failing plant back to norm: audit, corrective plan, execution, handover.
Manpower supply: Certified operators, supervisors and chemists deployed to client-run plants.

What happens every month

Daily operationShift log, dosing, sludge wasting, backwash, equipment checks, housekeeping.
TestingInlet and outlet parameters per the consent — daily on-site (pH, TSS, DO, MLSS, residual chlorine) and periodic NABL lab analysis.
Preventive maintenancePumps, blowers, diffusers, membranes, dosing pumps, instruments — on schedule, logged.
Process reviewWeekly data review by a process engineer; dose and MLSS adjustments; early warning on trends.
Compliance reportingMonthly report with all results, consumption, downtime and corrective actions; PCB returns and audit support.
Continuous improvementChemical and power optimisation, reuse improvements, upgrade recommendations.

Plants we operate

ETP

Industrial effluent plants — physico-chemical, biological, ZLD.

ZLD

Evaporators, crystallisers and high-recovery RO trains.

Leachate / FSTP

Municipal and remediation plants.

Cooling towers

Chemical programmes with monitoring.

Why clients move their O&M to KEE

Because an engineer, not a labour contractor, is accountable for the outlet. Because chemical and power consumption are measured and reported, not guessed. Because the documentation survives an audit. And because when something breaks at 2 a.m., the person who answers the phone has read your P&ID.

Frequently asked questions

Do you take over plants built by other companies?

Yes. A takeover starts with a condition audit and a 4–8 week stabilisation period, after which we commit to outlet performance in the contract.

What does a comprehensive O&M contract cost?

It depends on plant size, technology, shifts and whether chemicals are included. We quote a fixed monthly fee after a site visit — most clients find it lower than their current manpower plus chemicals plus breakdowns.

Do you provide the compliance reports for the Pollution Control Board?

Yes — monthly reports with all test results, consumption and corrective actions, plus support for consent renewals and inspections.

Is there a performance guarantee?

In comprehensive contracts, yes — outlet parameters are guaranteed for a defined inlet envelope, with penalties and remedies written into the agreement.

Plant not meeting norms, or too costly to run?

Send the plant type, capacity and current issues — we reply with an O&M scope and monthly fee range within one working day.
