Attachment I • Section 11-62-03 Definitions "Individual wastewater system means a facility which is designed to receive and dispose of no more than 1000 gallons per day of domestic wastewater" • Section 11'-62-31.1(D) "I'he total wastewater flow into one individual wastewater system shall not exceed one thousand gallons and one individual wastewater system shall not serve more than five bedrooms, whether they are in one dwelling unit or two. • Section 11-62-34 (2)( A) "The minimum area for any absorption bed shall be based upon a flow of 200 gallons per bedroom per day and in accordance with Table III dated Apri] 15, 19971ocated at the end of this chapter." Attachment A-1 The Hualalai Elderly Housing Phase III development will be constructed on a 3.698 acre parcel of land subdivided out of an existing parcel identified by Tax Map Key (3) 7-5- 10:84. The parcel is located on the makai side of Hualalai Road in Kailua-Kona located on the west side of Hawaii Island. This proposed project includes 30 one bedroom dwelling units split equally between six buildings configured into two `wings". A separate Common Room houses laundry facilities (absent in the individual dwelling units), an administrative office and a separate restroom. It is proposed to provide two separate Individual Wastewater Systems (fWS) for each 15 dwelling unit wing and a separate system for the Common Room for a total of 5 IWS. Flows from each dwelling unit wing will be split with wastewater from 7 dwelling units directed to one IWS and 8 dwelling units being directed to another IWS. In that laundry facilities are not installed in the individual dwelling units and are instead located within the Common Room, daily wastewater volumes for each dwelling unit are considered to be 170 gallons per day. The wastewater volume for the Common Room is an aggregate of discharge from laundry activities, 30 dwelling units x 30 gallons per unit (900 gallons per day), two office workers (30 gallons per day) and Common Room bathroom use (150 gallons per day). Wastewater flow volumes are summarized in the following Table 1: 7 Unit IWS 1,190 Gallons er Da Each 8 Unit IWS 1,360 Gallons er Da Each Common Room 1,080 Gallons Per Da Total Pro~ect Flow 6,180 Gallons er Da Table 1
