Water Management

Our Water

Grenada’s water comes from rain, and it has to be captured, treated and delivered close to when it arrives. Managing the resource is a daily job, not a seasonal one.

PROTECTING THE CATCHMENTS

Protecting the catchments

Our water starts in the forested interior. The condition of that land decides the quality of the water reaching our intakes: clearing, burning and farming close to a watercourse all put more soil and more contamination into the river, which means harder treatment downstream and more of it.

CUTTING LOSSES

Losing less along the way

Not every gallon we treat reaches a customer. Some is lost through burst mains, ageing pipework and leaks that never surface. Cutting those losses is the cheapest water available to us. It costs less than building new capacity, and it is faster.

Leak detection

Crews survey the network section by section using listening equipment to find leaks underground, before they show up in the road.

Valve regulation

When supply is short, we manage flow across the network by adjusting valves so that water reaches the areas that would otherwise go without. It's why pressure varies through the day in some areas, and why a scheduled interruption in one district keeps another one supplied.

PLANNING FOR THE DRY SEASON

Planning for the dry season

Production tracks rainfall closely. From January onwards river levels fall, and we plan restrictions, trucking and valve schedules around what the catchments are actually producing. Water is trucked to areas affected by drought and to communities with no pipeline.

A changing climate

Rainfall patterns have shifted and evaporation rates have risen. Both mean less water reaching the rivers from the same amount of rain, and both are why storage and new sources are now a permanent part of our planning rather than a response to a bad year.

Building capacity

New sources, new storage and replacement mains are how the supply keeps pace with demand. Current work is listed on our projects page.
