Water Reuse Advantages
We face a global challenge to responsibly use and protect our supply of fresh water, yet all too often we overlook ways to guard and extend this precious resource… and that’s one of the reasons Envirocycle and Netafim were invented.
Today the new goal is to take that same treated water and return it through piping networks to homes and businesses where it can be used in outdoor applications that do not require pure drinking water, such as for irrigation. By doing so we reduce the strain on our potable water by using clean, but not potable water, for uses where pure drinking water is not needed.
On-site wastewater treatment systems support approximately 25% of all the homes in North America today, (about 50% of all suburban homes in the USA) they process about 3½ billion gallons of wastewater per day, and their numbers are on the rise as communities grapple with the infrastructure strain that new housing and commercial development puts on existing municipal treatment systems. Most commonly known as “septic tank” system, these units provide basic treatment to the waste stream and deliver the effluent to a drainfield.
These basic systems are not very sophisticated and are prone to failure rates as high as 25% as reported by the US EPA. They have been notorious for causing pollution of lakes, rivers and streams, not to mention surfacing issues that can occur in the drainfield. As they fail, many agencies are requiring that more effective treatment systems be installed in their place such as Envirocycle advanced wastewater treatment systems.
The good news is that today these sophisticated advanced treatment systems are available and do a far better job of treating the waste stream. Along with them, products like Netafim Bioline further support the treatment process by precisely delivering the effluent into the soil.
Soil is one of nature’s most sophisticated purification tools. Whether clay, loam or sand, soil is an extremely effective treatment tool. When we deliver just the right amount of waste water to it, at just right time, the soil effectively provides additional treatment before it reaches surface water or ground water supplies.
The key to success is delivering just the right amount of wastewater at just the right time to just the right spot. This is where other techniques fail and Netafim Bioline succeeds.
Septic tanks are nothing more than large chambers that allow wastewater to settle and separate. When the resulting liquid portion, or “effluent” leaves the tank, it moves to a drainfield. The field was typically built by digging out the soil and replacing it with stone and perforated pipes. This method is becoming less popular today because it does not provide the precision needed to evenly disperse the wastewater into the soil. Instead, it simply “disposes” of it, and often in an unhealthy way.
On the other hand, Envirocycle treatment systems when combined with Netafim Bioline dripperline delivers extremely clean effluent into the soil with great precision, ensuring that the effluent does not flood an area or become exposed to people or animals. By distributing the effluent into the ‘biologically active soil horizon’, we not only allow the soil to further clean the effluent, we also allow plants, trees, bushes and grass to use it, along with its nitrogen and phosphorus content-two of the three ingredients in fertilizer. This ecologically sound process helps protect against the contamination of lakes, rivers, streams and drink water sources, it prevents objectionable odors, and it provides an important benefit – the “wastewater” is no longer “wastewater”. It is reusable, renewable and beneficial water that becomes a supplement to or replacement for an irrigation system. What does not get used by the plants is effectively treated by the soil so that when it does reach groundwater or other bodies of water, you can be assured that it will not cause harm to our ecosystem.
- Envirocycle® + Netafim Bioline® Advantages
- Allows for development and building in locations previously unsuitable
- Ideal for difficult site conditions such as clay, shallow soils, steep slopes, or high water tables
- Ideal for small lots
- Ideal for sites near bodies of water and other environmentally-challenging areas
- Can be an important part of any ‘green’ construction project
- Provides the best technology available for recycling water, allowing the landscape to use available nutrients such as nitrogen and phosphorus potentially reducing the dependence on fertilization
- Eliminates the risks associated with disposal methods such as gravel drainfields
- Requires a minimum of soil depth below the dripperline
- Achieves a balanced water distribution by applying the effluent to the soil’s biologically active zone
- Scheduled does and rest cycles throughout the day take full advantage of the treatment capability of the soil – cleaner water ultimately enters our waterways and groundwater supplies
- Minimum landscape disruption during installation
- Pressure compensating, continuous self-flushing emitters ensure a precise, slow distribution of wastewater into the soil and provide for long system life
