A ReWater® system creates numerous benefits for the owner including:

Lower Water Costs

By reusing the good water from inside a residence, money is saved every time someone takes a shower, bathes, or does laundry. That water is then used at least 30% and up to 60% more efficiently in ReWater’s drip network. The percentage of efficiency increase depends on your ambient wind velocity, humidity, and temperature, but these savings are significant. For example, in Las Vegas and other such areas that are hot, dry, and windy, your efficiency increase is about 60%. As water rates rise, you save even more money every year with a ReWater® system!

For detailed information on the efficiency 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.

Lower Wastewater Costs

Waste water reduction comes from the fact that you’ve reused half the water from inside your residence, or perhaps more from some commercial types of buildings, thereby keeping out the same volume of water from the sewage treatment plant, reducing that plant’s cost of operations, mainly by reducing energy demands, and decreasing chemical discharges into the environment. If your home is on a septic system, you reduce impacts to your precious leach fields by up to 50%! This is accomplished by not only removing the sheer volume of water and placing it at the root zones for plant usage, but also by introducing greywater’s inherent solids, which are almost exclusively organic, into the upper layer of the soil, which has a high degree of microbial activity. There, indigenous microbes in the soil ingest those solids, producing mainly fulvic and humic acids, which are literally plant food.

Some sewer districts have formal rate reduction schedules for our systems, especially in their commercial rate schedules. All that is usually required for receiving the reduction is a greywater meter and documenting the use for them. Most 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 use is, the lower your year-round sewer bill automatically becomes. In California, state law requires that the rate they charge must consider the actual amount and type of wastewater they have to treat.

Lower Maintenance Costs

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 tripped over. Playful or bored children have no access to it.

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 is what causes stucco to disintegrate, windows to spot, and mortar between bricks to leach away. Drip eliminates the expense of remedying those complications.

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 too. 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(s) that day, at midnight the ReWater system automatically supplements any balance of that day’s irrigation program(s) 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.

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!

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 Damage

By placing water directly in or on 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!

Healthier Plants

By using sprinklers on the surface, where it is hot and 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, 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 rainstorm!

Fewer Weeds

By placing water in the soil only where you want to irrigate, not in the air, most weed seeds blown in on the breeze find dry topsoil and most will not germinate.

Below the surface, where the water is, it’s a different story. It’s moist down there and that is where the roots of the landscaping plants are!
