Lower your water costs
By reusing the good water from inside a residence, you save money every time someone takes a shower, bathes, or does laundry. That water is then used 30% – 60% more efficiently in ReWater’s drip network. That percentage of increase depends on wind velocity, humidity, and temperature. For example, in the Inland Empire and other hot, dry, windy areas, your increase is about 60%. As water rates rise, you save even more money every year with a ReWater® system!
For detailed information on the effciency of underground drip irrigation, see the 1998 report prepared by the US Department of Agriculture, C.R. Camp, which compiled all the available literature on underground drop irrigation and analyzed it.Return to Top
Lower your wastewater costs
Wastewater reduction comes from reusing half the water from inside your residence or commercial buildings. This keeps the same volume of water out of the sewage treatment plant. In turn, that reduces the energy and chemicals needed to treat it. This also reduces discharges into the environment.
Some sewer districts have rate reduction schedules for our systems. All have reductions in their commercial rate schedules. All that’s usually required to receive the reduction on your bill is a greywater meter documenting usage for the district.
Some residential sewer rate schedules are based on your fresh water usage in the supposedly “non-irrigated” winter months. With that type of rate schedule, the lower your winter water usage is, the lower your year-round sewer bill automatically becomes.Return to Top
Save your septic system
If your home is on a septic system, you can reduce impacts to your leach fields or pits by up to 50%. This is accomplished two ways. First, greywater irrigation removes a huge volume of water from your system that allows your disposal system to dry out faster. Second, that process delivers greywater’s almost exclusively organic solids into the upper layer of soil. Indigenous aerobic microbes in topsoil ingest those solids, producing mainly fulvic and humic acids. Those acids are literally plant fertilizer. Roots then absorb the water and its nutrients.
ReWater’s underground drip system stays in place all the time. In the ground, the tubing carrying the water is not susceptible to being yanked away by garden tools, chewed by dogs or wild animals, or tripped over. Playful or bored children have no access to it.Return to Top
Lower maintenance costs
Contrast this process with a leach field, which disposes of those solids deep in the soil where only anaerobic microbes live. In those conditions, the unbroken-down solids are left to line the interior walls of the leach field and eventually clog it, causing expensive repairs years later.
Drip systems prevent irrigation run-off and its consequential erosion. Erosion is what causes those unsightly gullies on slopes. With drip, there is no run-off, thus no erosion. Sprinkler over-spray causes stucco to disintegrate, windows to spot, and mortar between bricks to leach away. Drip eliminates the expense of remedying those complications.Return to Top
Quick return on investment
The ReWater System is the only irrigation system that pays for itself because it is the only system that provides its own water. That water has value as irrigation water, and our system uses it extremely efficiently. That water also has additional value from being removed from the wastewater treatment stream. In areas where your wastewater rates are tied to your fresh water usage, the wastewater value from a ReWater system is as much or more than the fresh water value.
If no reusable water is produced on any given day, or not enough water is produced for the irrigation program that day, the ReWater system automatically supplements any balance of that day’s irrigation program with city water. This supplemental city water is then used 30% – 60% more efficiently in ReWater’s underground drip irrigation network.
Once the system pays for itself, it returns a profit. By using our cost/benefit analyses spreadsheet, you can determine how fast a system will pay for itself. Simply input a small number of years into the “system life” cell of the spreadsheet. Start with “10”, then look at the bottom cell on the lower right side. If that cell is still a positive number, then input a smaller number into the “system life” cell until the bottom cell reaches “0” or near zero. “0” in that bottom cell indicates the system has paid for itself. From that point, adding additional years to the system’s life expectancy increases the amount of money you earn from the system.Return to Top
Qualification for federal funding
Because a ReWater system reuses water, increases irrigation efficiency, reduces wastewater, eliminates irrigation run-off pollution, and reduces urban run-off pollution, our systems pay for themselves extremely fast when all these financial savings are combined, as they are for other municipal water projects. Our systems even remove the majority of surfactants (surface acting agents) found in residential greywater and put them in soil, which is the only known method for mitigating them (municipal sewage plants do not mitigate surfactants, which are known to mimic female hormones if unmitigated). Our systems qualify for the US EPA’s low-interest State Revolving Fund loan program. Don’t let anyone tell you otherwise.
Our systems also qualify for the same federal and state grant and loan programs that other water recycling, new water source, and water conservation methods qualify for. (If you didn’t realize those are three separate funding categories, welcome to the world of water.) State funds are often used as matching funds for federal grants and loans. At half the cost of desalinization and almost all municipal water reclamation programs, the ReWater system is by far the most cost-effective of all methods!Return to Top
No evaporation, overspray or runoff
With ReWater’s underground drip irrigation system, there is no evaporation, which causes between 30% and 60% of all water in a sprinkler system to simply vanish into thin air.
In a hot, windy area, you can expect 60% losses from sprinklers. On the coast, at least in wind-protected areas, losses are closer to 30%. Both are huge loss factors over time that will cost you more and more money as water rates rise.
Sprinkler over-spray can lose another 20% of the water. The larger the perimeter of the yard to be sprinkled, the greater the over-spray loses will be. Ornate designs have even greater over-spray losses.
With underground drip, there are never broken sprinkler heads to replace. Broken sprinkler heads create instant run-off and are a leading cause of commercial water losses.
Run-off carries silt, animal feces, pesticides, and fertilizers onto adjoining property and into waterways. Regional Water Quality Control Boards are cracking down on this well-documented problem. With underground drip systems in place, the surface becomes a catch basin for run-off, instead of a source of run-off. This fact can help you cost-effectively satisfy the new run-off regulations!No window spotting, fence or stucco damageReturn to Top
No window spotting, fence or stucco damage
By placing water directly in the soil instead of in the air, water will not end up on your windows, fence, or stucco.
Take a look at homes that have used spray irrigation for a while. Sprinkler damage is one of the largest sources of repair costs at a residence. In fact, sprinkler damage is the most common payout for builders.
You can stop this damage before it happens by installing a ReWater system!Return to Top
When using sprinklers on the surface, where it is hot, dry and highly evaporative, roots come to the surface and become highly dependent on continued irrigation there. It’s a never-ending cycle of waste when you irrigate with sprinklers.
By irrigating underground as is required for a legal greywater irrigation system, roots grow deeper and become better able to find water already in the soil from natural sources and from residual irrigation. And with their roots deeper underground, trees won’t come ripping out of the ground in a windy rain storm!Return to Top
Below the surface, where the water is, is a different story. It’s moist down there and that is where the roots of the landscaping plants are!
By placing water in the soil only where you want to irrigate, weed seeds blown in on the breeze fnd dry topsoil and most will not germinate.Return to Top
