In the 1960s Biwater began working in the Americas, initially securing a number of equipment supply contracts. The company’s first regional turnkey project was the ‘Northern Range Valleys Water Supply Scheme’ in Trinidad and Tobago. At some of the highest altitudes in the Northern Range, three water treatment plants were constructed to provide drinking water to remote hillside communities. Storage reservoirs and supply pipelines were included in the contract scope to ensure that 24/7 supply could be maintained across the three population centres of Aripo, Acono and Luango.

  • 4 Regional offices
  • 45+ Years experience
  • 85+ Biwater employees
  • 7.3% Of group revenue*

Subsequently, Biwater have delivered projects across the Americas – South, Central and North America, as well as the Caribbean. The Group established its Desalination and Membrane Treatment Centre of Excellence (Biwater Inc.) in the United States following the acquisition of Advanced Environmental Water Treatment in 2005. Biwater Inc. now have more 1,703 million litres per day (MLD) of installed membrane treatment capacity globally.

Notably, Biwater’s ongoing work in Managua, Nicaragua provided the capital with its first large-scale wastewater treatment plant. Following commissioning in 2009, the plant is still operated and maintained by a dedicated Biwater team. In the 2010 Global Water Awards the team were presented with the Environmental Contribution of the Year Award (Distinction), for showing that “effective sludge management is affordable to all”.

Nicaragua

Operation

The delivery of the first wastewater treatment plant to serve the capital city supported Nicaragua’s efforts to clean-up Lake Managua. Biwater’s design and construction methodology aimed to minimise the plant footprint, overcome earthquake hazards, minimise power consumption and produce a viable sludge product for resale. Funds for the plant’s construction were provided by the German Development Bank (KfW). Biwater has gone on to receive extensions and addendums to its original operation and maintenance contract following construction. As a result, Biwater continues to run the day-to-day operations of the plant and has expanded its scope of works to operate pumping stations across the city’s collector network and two additional nearby existing wastewater treatment plants. At the time of completion, the plant was recognised for having the largest and most effective solar sludge drying facility in the Americas. In the 2010 Global Water Awards, the local Biwater team were presented with the Environmental Contribution of the Year Award (Distinction).
