Service Models
Water treatment without the capital expenditure. Or the headaches.
The Challenge
Why choose BOOT or Water-as-a-Service over owning your water treatment plant?
Capital expenditure on water treatment infrastructure competes with your core business investment. Operations and maintenance demand specialised skills most companies cannot retain. Compliance liability falls on your EHS team rather than a specialist. Navbharat Water's BOOT, Water-as-a-Service, and AMC models transfer the capital, complexity, and compliance risk to us.

How It Works
Two ways to get compliant water without owning the plant.
Navbharat Water offers two flexible service models — BOOT and Water-as-a-Service — suited to different capacity requirements, project types, and client risk appetites.
Build-Own-Operate-Transfer
Navbharat Water designs, finances, builds, and operates the plant on your site at zero CAPEX. You pay a fixed monthly service fee (₹/KL treated). After 10–15 years (as agreed), ownership transfers to you. Navbharat Water bears all maintenance, compliance, and operating cost risk throughout the term.
Water-as-a-Service
A pure operational model with no transfer clause. Navbharat Water owns and operates the plant indefinitely. You receive treated water at an agreed quality and price per kilolitre. SLA guarantees uptime ≥99% and outlet quality at all times. Ideal for clients who never want the operational burden.
Annual Maintenance Contract
For clients who own their plant but want guaranteed uptime and compliance. Navbharat Water's AMC covers scheduled preventive maintenance, emergency corrective response within 24 hours, spare parts, and annual SPCB compliance documentation. Fixed annual cost, no surprise repair bills.
Technical Specifications
Built for precision.
| Parameter | Value / Range |
|---|---|
| BOOT minimum capacity | 50 KLD |
| BOOT contract term | 10 – 20years |
| WaaS SLA uptime guarantee | ≥ 99% |
| AMC response time | < 24hours (emergency) |
| AMC scope | Preventive + corrective + parts + compliance docs |
| BOOT capex by Navbharat Water | 100% (client pays ₹0) |
| Transfer valuation method | Written-down value at transfer date |
BOOT contracts start at 50 KLD and run for 10–20 years. Navbharat Water finances 100% of capital cost; clients pay a per-kilolitre service fee (typically ₹15–25/KL depending on technology and capacity). The WaaS model offers ≥99% uptime SLA with outlet quality guarantees — if quality falls below spec, Navbharat Water supplies water by tanker at no charge until the plant is restored. AMC contracts cover all preventive and corrective maintenance with a 24-hour emergency response commitment.

How does a BOOT contract transfer CPCB compliance liability from your company to Navbharat Water?
Under BOOT and WaaS models, the CPCB/SPCB consent for the treatment plant is applied for and maintained by Navbharat Water. Navbharat Water's name appears as the plant operator on regulatory documentation. This means compliance liability for the treatment system transfers to Navbharat Water — your liability ends at the boundary of the treated water outlet. This is a material risk reduction for your organisation.
Navbharat Water holds CPCB/SPCB operator consent on behalf of client

Force majeure and Act of God provisions for regulatory changes
