Alternative Septic Systems by Sonomex LLC - Your Authorized Arizona Norweco Dealer
Pima County 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 Tucson area property that does not perc?
Much of the property in the Tucson area and surrounding Pima County does not perc due to
extremely rocky conditions, caliche, steep grades, and other property limitations.  Poor perc
means you'll need an alternative septic system.  
Alternative septic design options are
numerous and can vary greatly in cost and installation difficulty (further increasing cost).  
If
you need a referral to a qualified engineer for perc testing or
septic system design, please
contact us.

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

quality effluent.  The efficient aerator motor
draws only 3.5 amps.
