New sewage tank unlocks opportunity for more housing units

SAND ISLAND, OAHU (HAWAIINEWSNOW) - After three years of construction, a new sewage tank was unveiled Thursday that city leaders are calling "the egg."

It's the second digester and sludge storage unit at the Sand Island Wastewater Treatment Plant.

It has the capacity to handle waste from the entire metro area from Kuliouou to Red Hill.

This increased capacity means the city can now approve new housing units in the dense urban core.

"From Kuliouou to Red Hill, as soon as you turn on your water, flush your toilet, you know take a shower -- all that water comes right through here. Right through Sand Island. All your projects stemming from everything from ADUs to new construction projects, new developments. It all hinges on this one project," said city councilmember Joey Manahan.

The project goes back to the disastrous Ala Wai sewage overflow in 2006.

The federal government ordered the city to improve its sewage system, resulting in $5 billion in new infrastructure.
