• This is the first removal of sludge from the lagoons since the initial construction of the plant in 1989. Sludge removal occurs every 10 to 15 years as is typical for an aerated lagoon treatment system. Estimated sludge removal from this project is approximately 3,000 dry tons. • The construction work will occur in phases without interruption to the wastewater treatment process. • The project is funded by CWSRF monies which is being increased from $18 million to $23 million. F. KEALAKEHE WWTP EFFLUENT R-1 UPGRADE: • Working on executing a contract for R-1 design. • Focus group meetings and an interagency workshop took place during the first week of November. The purpose of the meetings was to solicit input from the community on the R-1 plan of approach. An additional public meeting is being considered sometime prior to the draft EIS publication. • The environmental process is ongoing. A draft EIS is anticipated to be published in November 2017 followed by 45-day comment period. • The long range plans for R-1 quality effluent began in 2007 as a phased approach. Phase I, which installs a reuse line between the Kohanaiki area and Kealakehe Parkway, is planned under the State DOT’s Phase II Queen Ka‘ahumanu Highway Project (see item C above). • The 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. G. WASTEWATER EQUIPMENT REPLACEMENT PROJECTS: • Pua Sewage Pump Station (SPS) Upgrade: Design of the upgrade to the Pua SPS is in progress. 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. • Hilo WWTP Administration Building Reroofing: Work on mold remediation is complete. The remaining work is sheetrock installation, painting, and HVAC work. The contractor for this work is waiting on the County permits. • ZOM Dilution and Assimilative Capacity Study: Field work for the Dilution and Assimilative Capacity Study for the Hilo, Pāpa‘ikou, and Kula‘imano WWTPs, in accordance with NPDES permit requirements, is to begin in December 2017. H. ULU WINI WASTEWATER TREATMENT PLANT: • The WWD continues to maintain stability of the treatment plant with the goal of achieving consistent process data and meeting the regulatory as well as 4
