2 <br /> SUPPLEMENTAL REPORT ON CARDEN'S MOBILE HOME PARK <br /> WASTE TREATMENT SYSTEMS <br /> In the County Commissioner's meeting on March 5, 1990, during a <br /> report by the OC Health Director concerning Carden's Mobile Home <br /> Park's existing discharging waste treatment system, the <br /> Commissioners directed that a supplemental report be prepared. <br /> The supplemental report was to include information on the status <br /> of all waste treatment facilities serving Carden's, particularly <br /> the existing conventional nondischarge septic tank systems. This <br /> report, along with the attached plan view drawing of the Carden's <br /> Mobile Home Park layout, represents the County Engineer's effort <br /> to clarify the situation regarding the existing, proposed and <br /> potential waste treatment systems at Carden's. <br /> Carden's is presently served by two discharging septic tank/sand <br /> filter systems and five conventional nondischarging septic tank/ <br /> nitrification field systems. The construction plans (see <br /> attached drawing) submitted to DEM for Carden's Mobile Home Park' s <br /> new package waste treatment facility show five existing mobile <br /> home sites presently containing homes (sites 3,4,5, 6 & 8) and two <br /> existing sites not presently containing homes (sites 2 & 7) tied <br /> into a large existing sand filter treatment system which <br /> discharges into a roadside stormwater drainage ditch for Hwy 70. <br /> An, additional mobile home site containing a home (site 1) <br /> presently ties into a smaller individual septic tank\sand filter <br /> system which also discharges to the Hwy 70 roadside ditch adjacent <br /> to the point where the large sand filter system discharges. The <br /> construction plans show that all of these sites will be utilizing <br /> the new treatment system. In addition the construction plans show <br /> that four addition mobile home sites presently containing homes <br /> and an existing frame house (sites 24, 25, 26, 27 & 28) , which are <br /> presently tied into a conventional nondischarging septic tank <br /> system, will also be tied into the new discharging treatment <br /> system. The existing discharge permit, which applies to Carden's <br /> existing discharging system as well as to the new discharging <br /> system, is for 6000 gallons per day. Generally waste treatment . <br /> design, by state and local regulation, uses a quantity of 120 <br /> gallons per day as that waste volume which is generated by one <br /> bedroom in residential use. The 6000 gallon volume which is <br /> presently permitted to Carden's would then accommodate 50 bedrooms <br /> or approximately 17 three bedroom residential facilities. If all <br /> of the proposed mobile homes and homesites listed above are tied <br /> into the new treatment system, somewhere between 26 and 39 <br /> bedrooms of the 50 bedroom total capacity (3120 to 4980 gallons of <br />
