The Intelligent Alternative

There is a much better way to approach septic system design. It is time to start taking a more professional, sustainable and creative approach to onsite wastewater systems. We have developed a program that works! We’ll take your septic repair, septic upgrade or new septic project from beginning to end. From comprehensive site evaluation, soil testing and design on through permitting and installation. Whether you have a challenging site that needs expert attention or just want the best service and a system that is sure to last … Call BioSphere Consulting!

Andrew Brownstone & Dave Quinn (Co-Owners / Principals)

Andrew and Dave together bring over 30 years of combined diverse work experience in the field of geology and engineering.

Andrew has worked as a local consulting engineering geologist and wastewater system designer for over 15 years. His experience and knowledge of the principles of earth science provides a critical advantage in the design of onsite systems which ultimately rely on a site’s specific soil conditions to provide sufficient functionality.

Dave brings extensive experience in system engineering. He has been working as an engineer designing, implementing and troubleshooting systems with pumps, floats, valves, filters and complex controls since graduating UCSD in 1994.

Throughout their careers, they have together successfully executed a vast array of challenging projects including residential septic system upgrades and repair designs and engineered onsite wastewater treatment system designs for commercial, institutional & mixed-use facilities. Their experience includes the design and permitting of hundreds of wastewater treatment and dispersal systems for single-family homes that incorporate “alternative” technology (enhanced / supplemental treatment) and sophisticated soil dispersal and irrigation systems.

As good friends since high school, Dave and Andrew are able to seamlessly co-manage projects and tag-team to navigate the often challenging regulatory process.

How Alternative Systems Work

Engineered onsite wastewater treatment systems offer a solution to problematic septic systems because they treat the septic effluent to advanced secondary levels (clear and odorless filtrate) that can be dispersed in near-surface soils using subsurface drip tubing or shallow (10”-deep) pressurized trenches.  By treating the effluent first, the slimy biomat that builds-up along the floor and sidewalls of the leaching trench, is prevented. It is this slimy biomat caused by organic loading that plugs up the soil and promotes progressive failure of a conventional leach field.

By discharging to the upper 6” to 16” of the soil column, evaporation and plant up-take assist in process and we are able to recycle the wastewater for use as landscape irrigation.  99% of the microbial populations of beneficial bacteria that live in the soil are known to inhabit the upper 16” where there is abundant oxygen and increased hydraulic conductivity.

By carefully micro-dosing discharge to the near-surface soils, we attenuate the flows over time and space by spreading the treated filtrate over a large area (landscape) thus greatly reducing the soil application rate and allowing the naturally occurring soil microbes to COMPLETE THE TREATMENT PROCESS …. ultimately removing the impact we have on the natural water cycle.  Compared with advanced alternative systems, conventional septic systems are problematic and unsustainable in the long-run.

    Hello Andrew, it has been a while since I worked with you. I had a very good experience then, my Client was happy and your work comprehensive. Now, it seems we may have another opportunity, and I am looking forward working together on this project. I have been hired to complete the permit for Jerry Erdmann and Juko Martina Holiday up in Ben Lomond. Your name came up when I was reviewing the file at the Health Services Dept. Pls. give me a call at 831 334 2383 at your earliest convenience. Thank you Andrew, Patrizia
