<br />• Aliʻi Drive Salinity Study: Work on sampling salinity to identify if seawater <br />intrusion is infiltrating faulty sewer pipelines along Aliʻi Drive has begun. Both the <br />Keopu SPS and Lanihau SPS service areas show I/I occurring during high tides. <br />Hale Halawai SPS shows little or no salinity resulting from sea water I/I. CCTV of <br />the affected gravity sewers servicing the Lanihau SPS and Keopu SPS revealed that <br />numerous joints have separated. Approximately $200,000 has been directed to <br />purchase CIPP kits to seal the joints. Also, a new CCTV camera has been <br />purchased to video the laterals in this section. Crews have started to install the <br />CIPP kits from the week of 07/27/20. Approximately 700 LF of sewers were lined <br />with the CIPP kits to date. On 08/17/20, work was suspended for the Lanihau <br />Force Main replacement project. Line crew was moved to help assist contractor <br />for wastewater diversion to Keopu SPS during this construction work. <br /> <br />E. NORTH KONA SEWER PUMP STATION <br />• This new sewer pump station will be located on the mauka side of Queen <br />Kaʻahumanu Highway. It is to receive wastewater from a portion of the area <br />below Ane Keohokalole Highway between Hina Lani Street and Kealakehe <br />Parkway. The wastewater will be pumped to the Kealakehe WWTP via new force <br />mains. The new sewer pump station is scheduled to be complete in July 2022. <br />• The preliminary engineering report for the new pump station has been finalized. <br />• The Environmental Assessment (EA) process has begun. Consultant was issued a <br />NTP in late December 2019. Draft EA is expected to be complete by November <br />2020. <br />• The county is working on land transfer from West Hawaiʻi Business Park (WHBP) <br />for the SPS site. WHBP received Final subdivision approval in August 2020. <br /> <br />F. FACILITY REPAIR/EQUIPMENT REPLACEMENT PROJECTS: <br />• Pua Sewage Pump Station (SPS) Upgrade: Design items for additional upgrades <br />needed besides pump replacement at the Pua SPS are being worked into a new <br />contract. It will include a complete renovation, including structural, electrical, and <br />mechanical upgrades to the pump station. Cause for renovation is due to <br />deterioration of the wet well from HS; electrical component damage due to HS <br />22 <br />corrosion and the overall age of the facility; and mechanical damage due to faulty <br />discharge line valves due to hydraulic surging. Work is to include upgrading the <br />HVAC; replacing/upgrading components of the electrical system; replacing <br />corroded duct work; upgrading the wet well level control system; and improving <br />on safety issues by eliminating fire and electrical hazards to achieve compliance <br />with NFPA 820 and 70E. DEM is now preparing a Preliminary Engineering Report <br />so the project can qualify for a CWSRF loan to support design and construction. <br />• Pua Force Main (dual FM): DEM is applying for a CWSRF loan for the design effort. <br />CWSRF has placed loan application on hold pending submittal of a Preliminary <br />Engineering Report (PER). County will be attempting to prepare a PER with <br />excerpts from the initial 1990 design. CWSRF has initially approved PER and is <br />preparing commitment letter for funding design. <br />14 <br /> <br />
