Vuecrest Dr. Union, WA 98592 June 22,2023 Mason County Department of Health Services 415 N 6th St Shelton,WA 98584 RE: Virginia Devries Property(Parcel#42204-50-00092) Evaluation of Failure and Septic Upgrade from 2- bedrooms to 3-bedrooms Dear Inspector: Attached is a replacement/upgrade septic design for a property located at 521 N Mount Jupiter Dr, Hoodsport,WA 98548 in the Lake Cushman community. There is an existing 2-bedroom septic system that the records show was installed in 1983. The existing system has a 1,000-gallon septic tank and existing gravity trench drainfield 85' x 3' for a total of 255 s.f.. The septic was recently serviced for a home sale on 6-5-23 and the pumper noted a lot of back-flow from the drainfield even though the house has had limited occupancy. Upon further investigation,the drainfield was found to be plugged with roots. The manufactured home that was installed is 3-bedrooms, even though the assessor and septic records show it as a 2-bedroom. The buyer wanted to make sure the number of bedrooms in the home and the septic were equal. The old tank is to be removed and the old drainfield is to be abandoned. In order to increase the septic size from a 2-bedroom to a 3-bedroom, we are proposing a new 1,200 gallon 2-compartment septic tank with an effluent filter followed by a new 1,000 gallon pump chamber and(2) 10'x22.5' shallow pressure beds totaling 450 s.f..This is a compliant upgrade with 24"+of vertical separation. There are no surface water or well setback issues and we have designated a full reserve drainfield area.
