Form #: B-52 <br /> ' 7/18/91 <br /> DEPARTMENT OF FINANCE <br /> REQUEST FOR COUNCIL ACTION <br /> DEPARTMENT: Environmental Management DATE: 5/9/19 <br /> STAFF CONTACT: Dora Beck PHONE: ) 961-8513 <br /> A. REQUEST: <br /> An Ordinance authorizing the Mayor to enter into an intergovernmental agreement for a State Pollution <br /> Control Revolving Fund Loan for Wastewater improvement project and authorizing the issuance of <br /> $10,000,000 General Obligation Bonds of the County of Hawai'i for the purpose of financing the following <br /> projects: <br /> Na'alehu Wastewater Treatment and Disposal System and Drainage Modifications $7,000,000 <br /> N5'alehu Wastewater Collection System $2,000,000 <br /> Na'alehu Sewage Pump Station and Force Main $1,000,000 <br /> B. BACKGROUND AND JUSTIFICATION (USE ADDITIONAL SHEETS AS NEEDED): <br /> The Naalehu Community is currently served by a combination of Individual Sewage Disposal Systems and a <br /> County sewer system previously owned and operated by C. Brewer. The County is under a USEPA AOC to <br /> construct a secondary wastewater treatment facility to serve the community, close three large capacity <br /> cesspools (LCC), and replace and expand the existing wastewater collection system by September 30, <br /> 2022. <br /> The current collection system is comprised of substandard gravity lines that convey sewage from <br /> approximately 163 parcels to three large capacity cesspools. The AOC requires servicing all currently <br /> connected properties and a minimum of 30 additional properties. Based on wastewater flow projections, <br /> developed using 2017 City and County of Honolulu wastewater standards, the treatment and disposal facility <br /> would be designed for an average dry weather flow capacity of 225,000 gallons per day. <br /> Attachment A illustrates the parcels that would be serviced, the location of the conceptual new collection and <br /> transmission systems, and the proposed site for the new secondary wastewater treatment and disposal , <br /> facility. <br /> This request will provide funding for planning and design work for these projects and allow us to take <br /> advantage of the lower interest rates provided by the State Revolving Fund Loan Program. A request to <br /> increase the authorized amounts will be submitted when we have better estimates on the construction costs. <br /> The total costs of these projects, including construction,is currently estimated at approximately $70 million. <br /> re2 SIGNED: A1LI DATE: 6 /e52//r <br /> Department Head <br />
