Photo below is after we got the new driveway built, you can see the now cleared area with a small log deck and brush pile still to be moved/burned.
INTRODUCIING THE Newest construction worker TO JOIN foster septic AND EXCAVAtION Enoch Harland Linhard Foster Joined our team on Dec 30th 2015.
Already we have seen great growth in his skills and accomplishments and are confident that his abilities will continue to improve and expand with time. Although at this time his main job is keeping daddy (Richard Foster) working for diapers, this newest little excavator operator in training should be grown up and on the job in about 18 years.  Breaking out the old tank.   Photo above of Line to new tank. Photo below of transport line to the drain field.   Installing pressure lines and infiltrator chambers for the new drain field.   This pressure drainfield is 120 ft. A 30 ft, 40 ft, and 50 ft lateral. It was a tight spot to get that much drainfield into due to the fact the property line was close and it has to be a minimum of 5 ft off the property line.
 Finished Drainfield The design called for shallow trenches in order to maintain vertical separation. So in order to get enough cover over the infiltrator chambers some extra soil had to be brought in.
  Running the transport line from tank up to the new drainfield location.  The new tank backfilled. 
The old drainfield had failed and sewage was surfacing due to being buried too deep. In order for a drainfield to function properly it has to get oxygen in order to promote aerobic bacteria and avoid anaerobic bacteria. If the drainfield can't get oxygen due to being too deep or being covered with too dense of soil then the anaerobic bacteria can take over and secrete a black impermeable layer referred to as biomat. Once biomat is built the effluent can't drain into the soils and instead comes to the surface. In order to solve this problem the new drainfield is buried shallow (trench depth is 8 inches) and topped with a thin layer of topsoil (6 inches) to allow for plenty of oxygen to get through so that the new drainfield will have a long, healthy life.  |
who are we?Hi we are Richard
and Virlinda Foster. We live on a beautiful five acre piace of land on San Juan Island and love it! And we can't leave out the dog in our life, at not quite a year old Bella is a bundle of energy, all licks and wiggles who lives for car rides and people coming to see her. When Richard is not digging up something for you or working with your septic systems he enjoys hiking, camping, taking care of our property, growing fruit trees, mowing grass and of course playing with Bella.
