E. KEALAKEHE WWTP EFFLUENT R-1 UPGRADE: • The environmental process for the R-1 system is ongoing. A draft EIS was published 02/23/19, to be followed by a 45-day comment period. • A Public Information Meeting and Open House has been scheduled to take place on 03/25/19. • 90% plans are to be submitted to the WWD by 04/19/19. • The long-range plans for R-1 quality effluent began in 2007 as a phased approach. Phase I work installed a reuse line between the Kohanaiki area and Kealakehe Parkway. • DOH has earmarked SRF monies in the amount of $54 million to fund both design and construction of the R-1 upgrade at the Kealakehe WWTP. F. NORTH KONA SEWER PUMP STATION • This new sewer pump station will be located on the mauka side of Queen Kaʻahamanu Highway. It is to receive wastewater from a portion of the area below Ane Keohokalole Highway between Hina Lani Street and Kealakehe Parkway. The wastewater will be pumped to the Kealakehe WWTP via new forcemains. The new sewer pump station is scheduled to be complete July 2022. • The pre-design phase, including the archaeological and permitting assessments, has begun. The Preliminary Engineering Report (PER) is in process and will be submitted to WWD by 3/22/19. Once the design concept is determined, a follow-up meeting will be scheduled with Hawaiian cultural groups and archaeologists to discuss impacts to the Māmalahoa Trail. G. WASTEWATER EQUIPMENT REPLACEMENT PROJECTS: • Pua Sewage Pump Station (SPS) Upgrade: Design items for additional upgrades needed besides pump replacement at the Pua SPS is being worked into the contract. It includes a complete renovation to include the structural, electrical, and mechanical upgrades to the pump station. Cause for renovation is due to deterioration of the wet well from H2S; electrical component damage due to H2S corrosion and the overall age of the facility; and mechanical damage due to faulty discharge line valves due to hydraulic surging. Work is to include upgrading the HVAC; replacing/upgrading components of the electrical system; replacing corroded duct work; upgrading the wet well level control system; and improving on safety issues by eliminating fire and electrical hazards to achieve compliance with NFPA 820 and 70E. The project is funded by CWSRF monies. • ZOM Dilution and Assimilative Capacity Study: The Hilo final study has been completed in preparation for submittal with the NPDES permit renewal due on 03/20/19 for the Hilo WWTP.
