Coordination with the Lanihau Force Main Replacement Project and the Ironman (if held) will need to occur. E. NORTH KONA SEWER PUMP STATION • This new sewer pump station will be located on the mauka side of Queen Kaʻahumanu 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 force mains. The new sewer pump station is scheduled to be complete in July 2022. • The preliminary engineering report for the new pump station has been finalized. • The Environmental Assessment (EA) process has begun. Consultant was issued a NTP in late December 2019. Draft EA is expected to be complete by August 2020. • The county is waiting for land transfer from West Hawaiʻi Business Park (WHBP) for the SPS site. WHBP needs to subdivide land before transfer to the county. Land transfer is expected to occur by June 2020. Currently WHBP is still waiting for subdivision approval. F. FACILITY REPAIR/EQUIPMENT REPLACEMENT PROJECTS: • Pua Sewage Pump Station (SPS) Upgrade: Design items for additional upgrades needed besides pump replacement at the Pua SPS are being worked into a new contract. It will include a complete renovation, including structural, electrical, and mechanical upgrades to the pump station. Cause for renovation is due to deterioration of the wet well from HS; electrical component damage due to HS 22 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. DEM is now preparing a Preliminary Engineering Report so the project can qualify for a CWSRF loan to support design and construction. • Pua Force Main (dual FM): DEM is applying for a CWSRF loan for the design effort. CWSRF has placed loan application on hold pending submittal of a Preliminary Engineering Report (PER). County will be attempting to prepare a PER with excerpts from the initial 1990 design. • Lanihau SPS Force Main Replacement: Construction bids have been received, and anticipated NTP to construction contractor (JW Glover) is on 06/10/20. Project will replace approximately 800 lineal feet of pipe form the Lanihau SPS and connect to the manhole at the Palani Road and Kuakini Street intersection. Construction team mobilized on 08/17/20 with anticipation that work will be complete by late September 2020. • Repair/Replace Hilo, Kulāʻimano, and Pāpa’ikou WWTP Programmatic Plans: All three WWTPs are nearing the end of their useful life along with being located in corrosive atmospheres, expediting the aging process. Kulāʻimano WWTP is 14
