<br />Orangs County - Living Machine Proposal <br />innovative Design <br />Design Proposal for a Living Machine at grange <br />County's Northern Human Services Center <br />Northern Human Services Center <br />The site for the project is the Northam Human Services Center, boated off Si6~Mnoaef~~Cedar Grove, <br />Orange County. Previously an elementary school, the building is now used as government offices by Orange <br />County. Sited on the southwest comer of the bt EB a softball field, shared with the community. <br />Orange County wishes to renovate the facility in a manner that h~hlights various sustainable features. and sets an <br />example fw the region. Several sustalnabis features are currently being evaluated by the County, inducting <br />daylighttng and energy-eficisnt building shell strategies, energy-efifdent mechanical and electrical systems, <br />green building produdsR sustainable site design and water conservation and management systems. <br />As part of the renovation and extension of the facility, the existing wastewater treatment system. that presently <br />processes 2,700 galbns per day (gpd), is to be expanded to a fatal treatment capacity of 6,000 gpd. To <br />accomplish this treatment in an environmentaNy sound manner, Orange County is now desiring tD implement an <br />innovative, natural and biologically diverse wastewater treatment system equal th or equivalent to a Wing <br />Machine approach. This innovative, natural wastewater and reclamation system uses plants in water gardens to <br />naturally perform water purification procxsses. <br />Project Scope <br />Innovative Design's team will design. assist in biddlttg, and provide construction administration services to Orange <br />County in implementlng a Living Machine type system capable of treating up to 6,000 gpd of wasth. The water <br />will be biologically treated through a system of ponds. The tent is to have the treated water disposed of onsite. <br />The most 8kely approach to be incorporated for this project is a tidal vertical flow ('iVF). The TVF constructed <br />wastewater treatrnent wetlands operate by cydic flooding and draining through a media bed wrth cycle periods of <br />a day or less. The cycle period of a day or less distinguishes these technobgies from other flood and drain <br />systems. The tertiary LTeated effluent would be discharged into either a (1) sut>surfaoe nitrification fiekd, (2) <br />subsurface drip irrigatbn system or (3) surface drip irrigation system. The choice of these three options will <br />depend upon the first phase of tMa project; a detailed assessment of the existing. site and the establishment of <br />priorities of County. <br />Orange Coungra t.lvirg FMdr~ n~ur.. ear wowwe wwr <br />Z 'd 89£t'~N N91S34 3AIldA0NN1 YVdd9~! £OOd '9 '^~N <br />
