Hello and thank you for considering us to provide you with a bid for your Onsite Sewage System.

We have been installing septic systems in this area for 18 years and have become the industry leader in workmanship, innovation, and guarantees. You will find that we are typically not the cheapest price, but beyond a doubt, the best value around. The bitterness of a poor job remains long after the sweetness of a “good deal”. We have listed below just some of the areas that we put in the extra effort to provide you with a system that will provide you with a lifetime of service.

Zabel A100 effluent filter and conditioners
These units are installed on the outlet pipe of your septic tank and replace the standard baffle or screened baffle. Tests have shown that these units provide effluent filtering and conditioning capabilities that far exceeds standard requirements. The A100 is a top of the line filter at eighteen inches in diameter with an easily removable and reusable cartridge. The cartridge consists of 27 screening and growth plates for exceptional filtering.

Aquaworx digital timed dose controllers
Standard controllers have limited dose controlling capabilities, no data recording capabilities, use a host of mercury filled float switches that are moisture sensitive, wiring procedures that can lead to pump amperage problems due to length of wire runs, noisy contractor start switches, and are difficult to wire. The Aquaworx digital controller uses water transducer technology to eliminate all mercury control switches, has data recording capabilities for 4000 events, dual pump timers with veto settings allowing for less frequent dosing during normal usage, simple wiring, and a noiseless solid state relay for “ramped” pump starts, extending pump life.

Schedule 40 pipe
Strong and flexible schedule 40 piping is used in the supply and distribution networks for your drainfield and sandfilters. Schedule 40 pipe far exceeds standard class 200 piping for strength and resistance to cracking and freeze damage.

1.5″ Crushed washed gravel
We worked with Meridian Aggregates to bring this innovative product to market and gain industry acceptance. The angular aspect of this material allows for a greater void space and reduces gravel masking of your absorption area, essentially increasing your absorption area. Not to mention the product is consistently free of sediment and fine particulates which can clog the soils micro channels in the drainfield.

5 year installation guarantee
We are leading the industry with our standard 5-year installation guarantees and professional service. Our every intention is to provide you with a system that will provide you with a lifetime of trouble free usage. It is with extensive training that our qualified technicians will install, service and maintain your Onsite Sewage System. If we find your system to have a defect due to improper installation, we will correct the defect promptly. This guarantee does not extend or cover system components, which have their own warranty, or cover malfunctions due to improper usage or maintenance.

Continuing employee education
Our employees participate in yearly ongoing continuing education programs. The Washington Onsite Sewage Association provides training at their Puyallup training center with a complete range of courses, The University of Washington hosts a biannual 3-day Onsite Wastewater short course, and we hold bi weekly in house educational programs. We are committed to providing the Onsite Sewage community with educated, honest, and safe technicians who are fully aware of the broad range of issues confronting them.

Hydrostatic and pressure testing
All concrete chambers are tested for a minimum of twenty-four hours to determine water tightness. In addition to protecting against sewage leaching out into the groundwater, this is done to prevent the possibility of groundwater leaking in to the system. Pressure testing is performed on the systems distribution and piping network to check for leaks and equal flows to the absorption area.

Gravelless chamber upgrades
We offer gravelless chamber upgrades to replace the gravel in your absorption area. Given the 60% masking that occurs from the gravel sitting on the soil, the chamber technology eliminates the gravel, effectively doubling your absorption area. We offer 24″ and 36″ widths to accommodate almost all drainfield configurations. Being a relatively new innovation, not all Health Districts have implemented the code changes to make this upgrade possible. Please call for more information regarding your site.

Employee ownership
Since our inception, we strive to provide our employees with a fair and enjoyable place to work. To that extent, the benefits that we offer to our employees include, 4 day work weeks, paid vacations, paid holidays, medical, dental, vision, and alternative care insurance benefits, assorted employee bonuses, a retirement program with matching funds and employee ownership. This is a career that includes a healthy share of hard work and we believe that if a person is doing a job that they enjoy, this is reflected in their workmanship. We have a combined experience of over eighty years with some of our first employees still here working now as partners. We are dedicated to raising the standard of workmanship and sincerely hope we can be of service to you.

Since its inception in 1987, Earthwise Excavation has built a reputation for service, innovation, and workmanship. We also strive to follow the path of an evolutionary corporation with sustainable business practices, employee ownership, community and philanthropic involvement. Customarily business and corporate ideologies have viewed environmentalism as a threat to the bottom line. We regard the sustainability imperative as an opportunity to gain competitive advantage, reduce costs, increase employee and customer loyalty, and stimulate greater innovation while improving the health of both the planet and people.

Some of our programs include using Biodiesel, a domestically produced fuel from vegetable oils, Green power, 100% of our electricity comes from the Stateline wind farm, Nimh power, Nimh batteries are rechargeable and are designed for effective recycling and provide longer charge/ recharge cycles. They do not contain mercury, cadmium, lead, sulfuric acid or arsenic, all highly toxic materials. FSC certified lumber We use Forest Stewardship Certified wood which comes from sustainably harvested forests in construction of our sandfilter liners. Nine percent of net to conservation, A minimum of nine percent of our net profit is directed towards Northwest area conservation programs.

Permaculture land design, Workplace recycle programs, Oil water separators, Oil spill kits, Stop work oil leak programs, Repair and rebuild preferences, Materials sourcing programs, lessening toxins and increasing recycled materials, are some of our other programs.

Conservation and the wisdom of erring on the side of caution serve as a backbone for our philanthropic direction

At Earthwise Excavation we are committed to doing business in a different way. We have provided superior excavation services to the Puget Sound region while at the same time promoted social and environmental causes. We feel strongly that businesses must take the lead by “inventing a future” that gives our children a chance to enjoy a healthy environment. Our activism around this philosophy has taken many forms including campaigns to reduce global warming, promote conservation and support organic farming. All these efforts have been bolstered by our own commitments to reduce energy use, waste and emissions. We have discovered what may have been known – that it feels good to do good, and that doing good work enhances our company’s success.

It may seem odd the combination, excavation and sustainability, but this is the front line of development. It is rewarding to know how many places we have been able to save simply due to the fact that we offer an alternative to the standard “clear and haul” mindset. We are hoping to raise the awareness of sustainable business practices so we ask that whether you use our services or not, please ask others about their programs and procedures

We offer a full range of excavation services and complete septic system servicing. We appreciate your time and the opportunity to assist you in your project, from the ground down. With that said thank you for your time and we look forward to a mutually beneficial relationship.

Best regards,

The Earthwise Crew
