Water Ecology Map1. Current State: Contradictory Data Requiring a Cautious Approach
Kazakhstan's open sources present two different datasets on water losses, and this in itself is part of the problem.
- Bureau of National Statistics data (official statistics): water losses in networks in 2025 amounted to 6.8% (180.7 million m³ out of 2.66 billion m³ supplied to the network). By this indicator, Kazakhstan appears to be in good shape.
- Industry and academic sources: network wear in certain regions reaches 60–70%, while water losses in the system average 20% nationwide. An academic study supported by the Ministry of Water Resources indicates that transmission losses in water supply systems average about 50% of supplied water, with total water network length at approximately 99,960 km, of which 18.6% is in worn condition.
2. Scale of the Problem in Monetary Terms
- Network wear: up to 81.69% nationwide (Committee for Regulation of Natural Monopolies data), with 60–70% in certain regions.
- Water losses: 20% (conservative). With 2.66 billion m³ supplied to the network, losses amount to ~532 million m³/year.
- Cost of lost water: the exact nationwide tariff is not disclosed, but even at a conservative estimate of $0.10–0.15/m³, direct economic losses amount to $53–80 million/year. Including emergency repair costs, network relaying, and secondary water contamination — total damage exceeds $100 million/year.
3. Administrative Division and Number of Plants
Kazakhstan has 17 regions and 3 cities of republican significance (Astana, Almaty, Shymkent). Total: 20 administrative units.
Proposal: 20 compact modular plants, one per region.
| Parameter | Value |
|---|---|
| Number of plants | 20 |
| Capacity per plant | 100 km/year (DN1000 equivalent) |
| Total capacity | 2,000 km/year |
| Composite price DN1000 (unified model) | $149/m |
| Cast iron analogue price (lower bound) | ~$400/m |
| Saving per meter (material) | $251/m |
4. Annual Economic Effect (20 plants × 100 km = 2,000 km/year)
| Saving item | Calculation | Annual saving |
|---|---|---|
| Pipe material | 2,000,000 m × $251 | $502.0 million |
| Logistics | (730,000 t cast iron − 120,000 t composite) × $250/t | $152.5 million |
| Installation | 2,000,000 m × $50/m | $100.0 million |
| Water conservation | 2,000 km × $68,800/10 km | $137.6 million |
| TOTAL | — | ~$892.1 million/year |
Even if halved (removing disputable assumptions on water losses and installation) — ~$446 million in net benefit annually.
5. Key Conclusions for Kazakhstan
Problem: Official statistics (6.8% losses) mask the real state of networks, whose wear reaches 60–70% in certain regions, while academic data indicates losses of up to 50%. The gap between reporting and reality is exactly the space where budget funds are lost and water does not reach consumers.
Solution: 20 modular plants by region. At a unified composite price ($149/m) and a confirmed difference from the cast iron analogue ($400/m), the annual economic effect amounts to ~$892 million, of which $502 million is direct savings on pipe material.
