Re: Pua Sewage Pump Station — Pump Replacement
The State Department of Health has indicated that funding through the State Water Pollution
Control Revolving Fund Loan Program will be available for the Pua Sewage Pump Station —
Pump Replacement project, which has an estimated cost of $2,300,000. This project is
scheduled to start in the first quarter of FY11 -12 and is included in the proposed FY11 -12
Capital Improvement Program Budget.
Enclosed is a bill for an ordinance authorizing the Mayor to enter into an intergovernmental
agreement for a State Water Pollution Control Revolving Fund Loan (SRF) of $2,300,000 for
this (Pua Sewage Pump Station — Pump Replacement) project; and authorizing the issuance of
general obligation bonds for the purpose of financing this improvement project.
Pursuant to the County Procedures Manual for Participation in the Hawaii State Revolving Fund
Loan Program, prepared by the Wastewater Branch of the Hawai'i Department of Health in April
1994, part of the loan application process requires a "resolution or ordinance passed by the
County Council which authorizes the SRF loan application and identifies the dedicated
source(s) of revenue (i.e., general obligation bonds) which will fund the project and repayment
of the loan with interest." The Council's authorization of the issuance of general obligation
bonds will serve as a pledge of its general obligation authority as security for repayment of the
loan and interest.

A. REQUEST:
An Ordinance authorizing the Mayor to enter into an intergovernmental agreement for a State Water
Pollution Control Revolving Fund Loan for Wastewater improvement projects and authorizing the issuance of
$2,300,000 General Obligation Bonds of the County of Hawai'i for the purpose of financing the following
project:
Pua Sewage Pump Station — Pump Replacement $2,300,000
B. BACKGROUND AND JUSTIFICATION (USE ADDITIONAL SHEETS AS NEEDED):
The State Department of Health has indicated that funding through the State Water Pollution Control Revolving Fund Loan
Program will be available for the Pua Sewage Pump Station — Pump Replacement project. This project is scheduled to start
in the first quarter of FY11 -12 and is included in the proposed FY11 -12 Capital Improvement Program Budget.
This project involves replacement of three (3) existing Flygt pumps with three (3) each 250 HP sewage pumps to maintain
the existing Design Capacity of the facility; installation of one (1) each 25 HP "Jockey Pump" to accommodate average daily
flows to the facility; replacement of the existing Control System including a redundancy and a manual override; and removal
of the existing Variable Frequency Drives which will no longer be utilized under the new control system scheme.
All pumps are projected to be Flgyt N -pumps having a unique impeller design demonstrating a high and sustained efficiency
by preventing the accumulation of fibrous and deleterious material on the impeller by forcing it into the volute. This non -
clogging and self - cleaning feature effectively reduces the energy consumption and resources spent in providing emergency
repairs and maintenance within the associated downtime. The hydraulic design of the Flygt N- impeller technology is
guaranteed to deliver energy savings of at least 25 percent when compared to utilizing a channel or vortex impeller
wastewater pump.
The control system scheme will be such that the 25 HP pump is utilized to accommodate average flows of 2 MGD for
approximately 75% of the time with one (1) 228 HP pump utilized during periods when flows exceed 2 MGD. Two (2) 250
HP pumps are activated under Peak Wet Weather Flow conditions with the third 250 HP pump providing redundancy.
