Alternative Septic Systems by Sonomex LLC - Your Authorized Arizona Norweco Dealer
Recent Testimonial:

The Norweco alternative septic system certainly meets our needs and exceeded our
expectations.  The septic system itself is simple, straight forward and easy to install, requiring
a manageable amount of excavation even in a very rocky soil.  It was easily configured to meet
the requirements of our site.  The most impressive part of the experience, however, was the
customer service from the Tucson Norweco representative.  The representative made himself
easily accessible for questions throughout the installation process and responded quickly
with clear information, facilitating the installation immeasurably.  He visited the site and helped
with installation when necessary.  He also worked closely with the ADEQ inspectors to ensure
that we had a rule compliant system that maintained the functionality of the septic system and
met state environmental quality rules and requirements.  As a result inspections went smoothly
and importantly we are confident that our system is both compliant and functional. His friendly,
helpful and knowledgeable support of our project was very much valued.

It was a pleasure from start to finish to work with Sonomex LLC on our Norweco septic system.

Do you own Arizona property that does not perc?
A percolation test (perc or sometimes perk), along with soil analysis, is the deciding factor an
engineer uses when designing a septic system.  Much of the property in Arizona does not
perc due to steep slopes, extremely rocky conditions, caliche, high clay content, and other
limiting conditions.  Poor perc means you'll need an alternative septic system.  Other areas of
Arizona perc too fast and require pre-treatment of effluent.  Nitrogen reduction may also be
required in certain environmentally sensitive areas.

Have you been told your residential alternative septic system will cost over
$20,000 (or $30,000 or $40,000)?  It doesn't have to.

Go Green!  You may hear that a lot these days.  Norweco alternative septic
systems are truly "green" systems.  The aerobic and anaerobic bacteria
process wastewater naturally.  After processing, your household wastewater
can be reused to water the landscape around your home.  If you are building a
"green" home that requires a septic system (or replacing an old system), tell
your builder you want a Norweco alternative septic system.
The Norweco Singulair Alternative Septic System is extremely simple in design, with
only one moving part, yet produces high quality effluent.  The efficient aerator motor
draws only 3.5 amps.
