Scaffold only — counsel review pending

Section headings and structure are in place for the DASS launch. Operative legal text will be inserted after Indian commercial-tech counsel sign-off (business#1 W1). Do not treat this page as binding until published without this notice.

This page substantiates range-based savings estimates shown on nivoryx.com and in the Nivoryx app. Nivoryx is pre-revenue — we do not publish customer case studies in v1. Figures are engineering estimates from secondary research, not guarantees.

No forward-looking guarantees

We do not claim “you save more than you pay” or guaranteed payback. Actual savings depend on your water supply pattern, tariff slab, tanker use, and pump efficiency.

Data sources (Delhi NCR v1)

Delhi Jal Board published domestic tariff (slabs w.e.f. 01-02-2018; 20 kL/month metered subsidy continued per Delhi Budget 2026-27) and supply timing patterns
MCG Gurugram FY2026 slab schedule and MCF Faridabad volumetric rate; Noida / Greater Noida / Ghaziabad flat-charge schedules
BSES Rajdhani / Tata Power Delhi, DHBVN and UPPCL electricity tariff schedules (published slabs)
Tanker market rate surveys (Delhi NCR range, 2025–2026 secondary sources)
Published household water consumption studies (transposed to typical 3–4 person homes)

Estimate methodology

Model baseline tanker spend and pump electricity from supply intermittency assumptions.
Apply automation benefit ranges from scheduled fill + dry-run protection (conservative / mid / optimistic).
Express results as ranges with footnotes on the savings calculator and Why DASS pages.
Replace ranges with measured Delhi pilot data as installs accumulate (target: 25 homes by month 3).

Savings calculator scope

The interactive savings calculator shows physical resource impact only— water litres, pump electricity (kWh), and CO₂ — from the user's overflow inputs. It deliberately makes no monetary savings or payback estimates: rupee outcomes depend on tariff structures that are ₹0-marginal for many Delhi NCR homes (DJB's free 20 kL/month metered allowance; flat charges in Noida, Greater Noida and Ghaziabad), so money claims are not substantiated and are not made. Model constants: overflow spill rate ≈30 L/min per HP of pump; pump draw HP × 746 W ÷ 65% motor efficiency; grid emission factor 0.82 kg CO₂/kWh (India average) plus 0.0003 kg CO₂/L for water treatment and distribution; equivalents use 3 L/person/day drinking water, a 75 W ceiling fan, and 21 kg CO₂/tree/year.

Limitations

Not a bill-back guarantee or revenue-share commitment.
Does not account for unreported manual pumping or non-standard plumbing.
Tariff revisions and tanker price spikes are not forecast.

Retention

Raw calculation inputs and version history retained ≥ 3 years per CCPA Misleading Advertisements Guidelines 2022 practice note (counsel to confirm).
