Nu-Water Aerobic Treatment Plant

Saturday, January 17th, 2015

The video attached is a video of a Nu Water Aerobic Treatment Plant by Enviro-flo.

 

The reason we need to have this level of treatment was for the stream and high ground water in this area.  We need to protect our surface and ground water from contamination.  The neighbors well is pretty close as well, so in order to have a home this close this homeowner agreed to have annual maintenance to this system.

Now annual maintenance does not mean it needs pumped out every year.  It just needs monitoring to ensure that we are not contaminating surface and ground water.

We take DO (Dissolved Oxygen) measurements.  This tells us how much Oxygen is dissolved into the water for the Aerobic Bacteria.  A low DO reading would indicate that something was wrong, and I would need to diagnose what.

We also take a Turbidity measurement as well.  Turbidity is a measurement of how much particulates are in the water being released into the drainfield.  It is measured in NTU or Nephelometric Turbidity Units.  Basically our meter passes light through the sample as is able to tell how much light makes it to the receiver.  If the sample is foggy, it will be a high reading.  In this case, it’s near drinking water.  .77 NTU or less than 1 NTU.

This system here is Level B treatment.  There is no Disinfection unit to clean or take care of, because this site didn’t require Level A Treatment.

Also, this system is functioning perfectly.  And will continue to do so as long as it is maintained.  It is normal to pump out the first two compartments every 2-3 years or so.  As to not have excessive solids build up in the plant.

Also note: this is a wastewater treatment plant.  Not too unlike a commercial plant like your city wastewater treatement plant.  The commercercial plant has operators there 24 hours a day 7 days a week monitoring it’s levels and ensuring the community and the environment that it is releasing pure water into the rivers and streams.

This client’s plant is a “Residential” version of the “Commercial” plant.  It is agreed that once per year should be okay for maintenance.  But make no mistake about it.  This system was very expensive and will not “Self Clean” or “Take Care” of itself.

The repairs to a plant that is neglected can reach 10’s of thousands of dollars.  And 100% of the time, the client won’t know damage is being done, until it’s too late and toilets no longer flush, or sewage is backing up in the yard.

Annual inspections only run $110 dollars in Clark County, Wa.   All of our rates are clearly posted on our website at http://www.firstcallseptic.com/septic-rates/
