Flexible Structures to Meet Customer Needs

With close to 50 years of project experience, IDE has built hundreds of desalination plants for customers under all types of contract frameworks, creating a track record unmatched by any other company.

Working with government agencies, municipal utilities, resorts, power utilities, refineries, mines, nuclear power stations and many other industries, IDE has developed the ability to truly understand the operational and financial needs of its clients. As a result, IDE is equally comfortable functioning as an equipment supplier, turnkey project integrator, sub-contractor or other requirements for all types of desalination and industrial water treatment projects.

In fact, IDE prides itself on its track record of successful co-operation with developers, contractors, operators and joint venture partners. IDE views these smooth-functioning partnerships as the key to its consistent record of delivering complex projects on-time, within-budget and to spec.

We Deliver in Different Ways to Meet Customer Needs


In Engineering/Procurement/Construction and Turnkey contracts, IDE assumes responsibility for all project phases until the plant is up and running, including engineering, manufacturing, delivery of equipment to site, supervision of erection, civil and marine works, commissioning and start-up. IDE has deployed hundreds of water treatment plants on a full or partial EPC/Turnkey basis, representing a total production capacity of approximately 3 million m3/day.


In Engineering/Procurement/Support Services contracts, IDE assumes responsibility for the design and procurement phases of the project including support services, as demonstrated in the Cape Preston plant in Australia, and the Carlsbad plant in CA, USA.

Water Sales (BOT/PPP/BOD)

IDE’s partnership models are designed to help customers manage risk and reduce water cost. Through PPP (Public Private Partnership) structures, the customer, who may have limited experience in the construction, operation, maintenance and finance of massive desalination and industrial water treatment projects, transfers risk to experts with the skills required to plan, manage, execute and operate these complex undertakings.

Possible models include joint ventures, strategic partnerships, Build-Operate-Transfer (BOT), Build-Operate-Own (BOO), Private Finance Initiative (PFI) and others. Within these frameworks, IDE accepts responsibility for building the project (including securing required financing), and then operating the facility under a long-term concession (ranging from 10-30 years) after which the plant is transferred to the customer.

Contracts usually include the sale of the water produced by the plant to governmental and municipal customers for a fixed price established in the contract. Over the past 15 years, IDE has taken on BOT projects of increasing size and complexity, each breaking previous records for desalination capacity and desalinated water prices.
