City officials sought to ease community members’ concerns over plans to truck raw sewage sludge from urban Honolulu to outlying communities.

The public meeting Monday night was held by the city as it continues planning for test runs later this month of trucking raw sewage sludge from Sand Island to Honouliuli Wastewater Treatment Plant to ease congestion on the Honolulu facility.

The city ultimately plans to haul the sludge to plants in Kailua and Waianae — in addition to Honouliuli — as it deals with delays in the expansion of facilities at Sand Island.

Hauling sewage sludge to the other plants is seen as a temporary means of relieving the over-capacity "digester" at Sand Island while the administration and City Council work out plans for the safest, most cost-effective way to expand the facility.
