Why Annual Running Cost Matters More Than Installation Price
Pakistan’s water business sector has seen significant growth. 18.9L refill shops operate across every residential area of Lahore, from Ichhra to Samanabad to Rehmanpura to Muslim Town. The installation cost of the 2000 LPH RO plant is a one-time figure. The operating cost is a recurring reality that determines whether the business is profitable.
A system that costs PKR 400,000 less at installation but has a PKR 150,000 higher annual operating cost is more expensive over 4 years, not cheaper. Aqua Prima includes estimated annual operating cost in every quotation. Most suppliers do not.
Annual Operating Cost — 2000 LPH on Lahore Bore Water
| Cost Category | Annual Cost (PKR) | Notes |
|---|---|---|
| Electricity (7–15 kW pump, 20hr/day) | 230,000 – 500,000 | At LESCO PKR 45–55/kWh, Sept 2026 |
| Sediment prefilters (4–6 sets/year) | 24,000 – 96,000 | High frequency on Lahore bore water |
| Carbon prefilters (2–3 sets/year) | 10,000 – 20,000 | Must replace on schedule |
| RO membrane amortisation (2–4 yr life) | 20,000 – 100,000 | With correct softener pretreatment |
| Softener salt (ongoing) | 25,000 – 60,000 | Depends on hardness and production |
| Antiscalant chemical | 35,000 – 80,000 | Higher rate for very hard Lahore water |
| UV lamp replacement (annual) | 6,000 – 12,000 | Replace regardless of lamp appearance |
| Service visits and inspection | 30,000 – 70,000 | Pump, TDS monitoring, general service |
| TOTAL ANNUAL ESTIMATE | 380,000 – 938,000 | Typical 2000 LPH on Lahore bore water |
Revenue Potential vs Operating Cost
A 2000 LPH system producing approximately 40,000 litres per day at 65% recovery can fill approximately 2,100 x 18.9L bottles per day. At a refill price of PKR 150–180 per bottle, this represents gross daily revenue of PKR 315,000–378,000 — and annual gross revenue of approximately PKR 115,000,000–138,000,000 at full capacity.
Annual operating cost of PKR 380,000–938,000 represents approximately 0.3–0.8% of annual gross revenue potential at full capacity. The operating cost is commercially manageable — provided the system is correctly specified for Lahore bore water and maintained properly.
The Hidden Cost: Premature Membrane Failure
On Lahore bore water without a water softener, a 2000 LPH membrane set fails in 12–18 months instead of 3–4 years. Emergency membrane replacement for a 2000 LPH system costs PKR 80,000–200,000. At 18-month intervals over 5 years, this adds PKR 220,000–600,000 to operating cost — on top of the production downtime during emergency repair.
The correct pretreatment — a water softener (PKR 100,000–180,000 once) — eliminates this cost entirely. It is the single most important investment a water business can make after the RO system itself.
Electricity Cost Deep Dive
Electricity is the largest single operating cost for a water business. A 10 kW high-pressure pump running 20 hours per day consumes 200 kWh per day. At LESCO commercial tariff of PKR 50/kWh (September 2026), this is PKR 10,000 per day — PKR 300,000 per month — or PKR 3,650,000 per year at that pump size.
Wait — that seems high. The pump may not run continuously; auto-shutoff during storage tank fill reduces actual runtime. Actual electricity cost for a well-designed 2000 LPH system with auto-shutoff and adequate storage is closer to PKR 230,000–500,000 per year depending on actual operational hours and pump specification.
Correct pump sizing for your actual source-water TDS (from a water test) avoids running an oversized pump that costs more to operate than necessary.
🔧 Aqua Prima Tip
Aqua Prima includes both capital cost and estimated annual operating cost in every quotation. This allows a fair total-cost-of-ownership comparison between suppliers — not just a purchase-price comparison.
Frequently Asked Questions
How much does it cost to run a 2000 LPH RO plant water business per month in Pakistan?
Approximately PKR 32,000–78,000 per month for a 2000 LPH system on Lahore bore water, including electricity, filter replacement, membrane amortisation, chemicals and servicing. Electricity at LESCO September 2026 rates is the largest single cost.
Is a water shop with a 2000 LPH RO plant profitable in Lahore?
Yes, when the system is correctly specified and maintained. Annual operating cost of PKR 380,000–938,000 versus gross revenue potential of PKR 115,000,000+ at full capacity represents a commercially viable margin. The critical risk is premature membrane failure from inadequate pretreatment, which can add PKR 200,000–600,000 in unplanned costs over 5 years.
How much electricity does a water shop RO plant use per month?
A 2000 LPH system with a 7–15 kW pump at 20 hours/day uses approximately 4,200–9,000 kWh per month. At LESCO commercial rates of PKR 45–55/kWh (September 2026), this is PKR 189,000–495,000 per month in electricity alone.
