CITY ANNOUNCES BEACHWALK EMERGENCY WASTEWATER BYPASS PLAN

               The City has activated an emergency design and construction team to build a temporary bypass line in the Waikiki area to prevent future diversions from the existing wastewater force main.

               Mayor Mufi Hannemann said, "This project is a top priority for the City. The health and safety of our residents and visitors are most important, and we must do everything we can to prevent a sewage bypass such as the one we had in March. As I have said so many times, our infrastructure needs our attention and it needs it now."

               On March 24, 2006, after weeks of intense rain, the 42-year-old existing force main ruptured on Kaiolu Street in Waikiki. The City had already initiated planning for a new permanent force main to begin in 2007 when the rupture occurred, but will now construct a temporary emergency bypass to prevent the need for any further diversions until the permanent line is completed.

               The bypass will generally parallel the existing 42-inch force main.  It will originate at the Beachwalk Wastewater Pump Station in Waikiki, be tunneled below ground along Kaiolu Street across the Ala Wai Canal to the mauka bank, then submerged on the Ala Wai Canal bottom to the Ala Moana Boulevard bridge, and terminate near the Diamond Head entry to Ala Moana Beach Park. The 7,200-foot line is expected to be completed by the end of this year.

               The bypass project will be constructed in two phases. The first phase will be the portion from the mauka bank of the Ala Wai Canal to Ala Moana Park.  Phase One also includes installation of  temporary pumps along both sides of the Ala Wai Canal that are intended to intercept and divert sewage flows from the existing pump station to the new bypass pipe.  This will provide a safety net until the second phase is completed.

               The second phase will construct an underground pipe by launching a state-of-the-art microtunneling machine from a pit on the mauka side of the Ala Wai Canal about 1,000 feet along Kaiolu Street to the Beachwalk wastewater pump station makai of Kuhio Avenue.

               Traffic will be intermittently affected along Kaiolu Street and at the Diamond Head entrance to Ala Moana Beach Park.  Some parking stalls and portions of the sidewalk will be temporarily displaced by the bypass pumps along the makai side of the Ala Wai Canal.

               On the mauka side, in the City's Ala Wai Neighborhood Park, the bike path will be detoured and a portion of the softball field will be closed for a construction staging site.

               Because of the urgency of the situation, the City has asked the State to issue an emergency proclamation for the project and waive the lengthy process to obtain permits for construction.  This will allow the City to proceed immediately.

               Mayor Hannemann asked for the cooperation of the community during several months of construction.  "There will be inconvenience for some people in this area, but we ask for your patience.  We believe the community understands the need for this work and wants it done quickly."

               The estimated cost of the Beachwalk Wastewater Emergency Bypass is $20 million. Of this amount, $2 million has already been spent for the repair work of the March 24 break and $3 million for environmental restoration which includes additional 'akulikuli plants in the Ala Wai Canal.

               "We are encouraging public input into this process, and we're going to extra lengths to keep the public informed about the project," said Hannemann.

               The project work includes a comprehensive community information process.  Information will be available to the public through a website www.beachwalkbypass.com, and a project hotline 808-203-5777.
