Water supplies in the Solomon Islands capital, Honiara, are being increasingly affected by logging upstream from the catchment.
Rapacious logging has seen the country's forests cleared by both legal and illegal loggers with little environmental oversight.
Last week, two logging sites upstream from the Kongalai catchment - where 40 percent of Honiara's water comes from - were blamed for the intake's shut down.
Solomons Water chief executive Ian Gooden says he's working with the government to close the logging sites.
"Even once these operations are shut down the damage is done, so we will continue to have sediment coming into the water system for months to come. Unless we can go in and revegetate or put silt traps or sediment fences in, that sediment's going to continue coming for a long time."
