Industry brief · Materials, infrastructure & industry
Water & wastewatersupply schemes, STPs, desalination
Bulk water supply, treatment plants, distribution networks, sewage treatment (STPs), water reuse and seawater desalination, delivered via EPC, DBO/DBOT, HAM (India's Namami Gange) and regulated-utility capex. India's Jal Jeevan Mission (INR 3.60 lakh cr, extended as JJM 2.0 to 2028) is the largest rural water programme; the US faces USD 625bn of 20-year drinking-water needs (EPA DWINSA); the EU recast Urban Wastewater Directive drives quaternary treatment. Water is a moderate reference class for cost (mean +20%) but Indian irrigation/water-resource projects show extreme overruns.

Approved 22 Mar 2026 to complete rural tap coverage by 2028; first INR 1,561 cr released 1 Apr 2026 to five states.
- Audit scrutiny of JJM quality2026-2028
CAG (Gujarat, Sep 2026) found 88.64% of water samples in 48 villages unfit, bulk pipeline delays of 3-25 months and INR 54.32 cr excess payments from incorrect price-index calculations.
- US drinking-water needs2023-2043
EPA's 7th DWINSA: USD 625bn over 20 years — distribution/transmission USD 422.9bn, treatment USD 107bn, storage USD 56.1bn, source USD 25.2bn; ~4 million lead service lines.
- Utility capex super-cycle2026-2035
American Water's 2026-2030 capital plan USD 19-20bn and 2026-2035 plan USD 46-48bn.
- Desalination cost decline2025-2035
Global capacity ~99 million m3/day (2023) vs 27 million in 2003; SWRO energy ~3 kWh/m3; new plants reporting ~USD 0.28-0.40/m3.
- UK water balance-sheet crisis2025-2030
Thames Water debts exceeded £20bn (Jan 2026), constraining AMP8 investment and raising regulatory/financing risk across the sector.
Research findings
- Reference class: water
Flyvbjerg et al. (2026): water projects mean real cost overrun 20% (N=265), 13.2% >50%; dams 71-75%.
- MoSPI water resources overrun
PAIMANA Mar 2026: 41 water-resource projects INR 1.18 lakh cr original vs INR 2.22 lakh cr revised (+88%); Polavaram INR 10,151 → 55,549 cr; waste & water (30 projects) only +0.7%.
- MoSPI Q1 FY26 anticipated cost
Water resources: 15 projects INR 15,428 cr original vs INR 61,880 cr anticipated (+301%) — dams/irrigation, not STPs, drive the extreme tail.
- Capibud schedule parse (water)
All 10 parsed water-resource projects were delayed; median delay 42 months on a 54-month median plan.
- JJM baseline
At launch (31 Mar 2019) only 18.33% of rural households (3.27 cr of 17.87 cr) had piped water; outlay INR 3.60 lakh cr, central share INR 2.08 lakh cr.

|---|---|
| United States | USD 625bn drinking-water need (DWINSA 7) plus wastewater needs (CWNS); IIJA SRF supplements and lead service line replacement; PFAS MCL compliance capex; regulated utilities (AWK) growing rate base ~8%/yr (estimate). |
| Europe | Recast UWWTD (2024) mandates quaternary treatment with producer responsibility for micropollutant removal and energy neutrality by 2045 (estimate); UK AMP8 record investment amid Thames Water crisis. |
| Middle East | World's largest desal market (Saudi, UAE, Israel); IWP concessions (ACWA Power); 2026 war raises security risk to coastal plants and energy supply. |

How Capibud uses this pack
A pack is a starting position, not a forecast. When a water & wastewater decision opens in Capibud, pack v1.0.0 is copied in and pinned to that decision. The 13 parameters, 11 swing factors and templates the committee saw stay attached to the decision record, even after the pack is next refreshed.
Parameter ranges and WBS durations seed the P50, P80 and P90 for capex, schedule and value. Your own estimates, vendor quotes and actuals replace pack defaults line by line, and the record shows which numbers are still defaults.
Each swing factor is wired to shared factors; here the heaviest are policy, labour, steel and electrical equipment. A move in one factor hits every exposed project in the same scenario, which is how the capital committee sees concentration across a book rather than project by project.
The 12 price feeds and 22 listed tickers feed the brain, which watches for drivers moving outside their pack range and drafts the change for a person to review.
