Total Water Solutions For Phased Expansion

Developers of Leeward Estates faced obstacles finding a supplier that could provide a phased, overall water supply solution to support staged expansion.  Plans called for a new resort, residences and mega-yacht marina at the exclusive 415-acre development, located on Providenciales in the Turks and Caicos Islands.


With new residences and Nikki Beach Resort nearing completion, the developers turned to Seven Seas Water to take charge of the entire water cycle. Seven Seas Water produced an increased, dependable supply of potable water to keep up with various stages of expansion. To complete the water cycle, a new wastewater treatment plant and central collection system provided environmentally friendly, low-cost irrigation water.

Seven Seas Water furnished a solution that required no up-front investment in equipment from the developers and transferred all responsibility for managing and operating the water utilities to Seven Seas Water. Under a build-own-operate arrangement, Seven Seas Water upgraded and increased the potable water capacity of a small, existing reverse osmosis plant on site.

Seven Seas Water constructed and installed a second, high-efficiency seawater reverse osmosis (SWRO) system with a capacity of 125,000 GPD. Sufficient infrastructure was installed to allow for doubling the plant capacity to keep up with future growth.  For added efficiency, both systems can be monitored remotely.

Seven Seas also designed a new central collection and modular, expandable Membrane Bioreactor (MBR) wastewater treatment system, and provided the treatment process and the reuse water distribution network. The state-of-the-art treatment for wastewater systems, MBR produces high-quality treated water for irrigation with no residual color or odor.  The MBR system is easily expandable with a small footprint – about half the size of a traditional wastewater treatment plant.  Modular designs of the MBR and SWRO systems ensure that future demands will be met easily. Reducing the energy demands of the original SWRO yielded increased energy efficiency and lower water costs.
