Rain First. Then the Sea.

Port Elysium OpCo 21

Port Elysium is its own water company. The estate captures the rain that falls on its roofs, roads and open ground, purifies it and puts it to work for drinking and irrigation; desalinated seawater makes up the rest and covers a dry year. Every drop of wastewater is treated on site and reused, and no untreated sewage is ever discharged near the lagoons or reefs.

The vision

Port Elysium Is Its Own Water Company

Long Island has no dependable fresh groundwater and existing homes rely on tankers. Port Elysium supplies its own drinking water and runs a full wastewater service from the first home, with the public utility only as backup.

Rain, landscape, lakes and stormwater are managed as one water system, and every metered connection is an income stream.

How it works

Four Simple Steps

  1. Capture. Rain from roofs, roads and open ground fills four lined reservoirs and is purified.
  2. Make. Desalination trains make the balance from seawater, mainly in daylight hours.
  3. Store & supply. Two days of storage feeds the drinking-water network 24 hours a day.
  4. Treat & reuse. Wastewater is treated on site and returns through the purple network; sludge goes to composting.
The most sustainable choice, layer by layer

The Technology

Rainwater capture

Swales and sumps feed lined reservoirs, and the water is purified for drinking and irrigation.

Desalination

Containerised plants with the latest energy-saving membranes make the balance, mainly in daylight on solar power.

Two days of storage

Enough stored supply, plus a spare plant, that a peak day or a breakdown never interrupts water.

Wastewater treatment

Compact plants on site produce reuse-quality water in one step.

Purple-pipe reuse

Treated water runs in its own separate network to landscape, toilets, farms and lakes.

Leak-listening meters

Every connection's meter listens to the pipe around the clock and flags leaks.

Capital Follows Sales

A few works are built once; everything else is added block by block as homes are completed: factory-built desalination trains, tanks and wastewater plants, each ordered when the roads or forecast demand cross a trigger, with pipes laid zone by zone by our own crew in the trenches cut with each road. The shortlisted desalination and wastewater suppliers have delivered and commissioned plants on Bahamian islands since 2024.

Delivery

Built and Run by Port Elysium

Equipment is bought from whichever country gives the best overall deal, and that country's export credit agency can fund up to 85% of eligible equipment, on terms of up to 22 years for water projects.
