Obtain financing to build or optimize a treatment infrastructure

You are convinced with all the benefits of combining Construction & Operation (Design Build Operate model) but:

  • You are reluctant to finance, on your own budget, the capital investment (Capex); this can be for various reasons:
    - You prefer to allocate your financing capabilities to serve projects that are more in your core business
    - You do not want to increase, or need to decrease, your debt levels & ratios…
  • You need to secure an affordable and predictable tariff/fee for the services that the asset is meant to deliver; tariff/fee is meant to cover
    - Fixed component for amortization and financing costs of the asset (new or expansion) + fixed O&M costs (manpower, asset maintenance, …)
    - Variable component for variable O&M costs (energy, chemicals, …).

Total or partial financing

1. Full financing

We structure the financing of 100% of the Capex, usually with a “project finance” scheme, as follows:

  • Special purpose company (SPC) created for the project
  • We provide for SPC’s equity, along with other partner investors
  • Equity shareholders secure a long-term debt, usually from a pool of lenders and on a non-recourse basis

2. Partial financing

We structure the financing for a portion of the Capex (still with “project finance” scheme), the remaining portion being financed by a third party, usually provided by you (typically, an International Financing Institution or a Grant provider)

The main benefits of Design, Build, Finance & Operate solution over Design, Build & Operate solution:

  • Capex financing is no longer on your balance sheet
  • You have a predictable tariff/fee in your budget to pay for the services rendered by the asset

Your main requirements for engaging into a Design, Build, Finance & Operate (DBFO) contract:

  • Capacity building: the DBFO is an elaborated collaboration model which requires that you staff well qualified team
  • Governance stability: DBFO requires long-term (typically, from 20 to 30 years) in order to optimize the tariff, which requires stability in the governance of your authority
  • Stakeholders management: DBFO involves several stakeholders (commercial lenders, international financing institutions or donors, regulatory agencies, non-governmental organizations, …) who need to be managed in good faith and persistently


In a Design, Build, Finance & Operate for a desalination plant, the cost of power to operate the treatment line can represented 50% of the water tariff, which confirms that over the full lifecycle of an asset, Operation & Maintenance costs are frequently the major component.

They trust us

We have dozens of references of water & waste treatment facilities delivered through Design, Build, Finance & Operate contracts (with full or partial financing of the Capex).
