Ecovie Rainwater Collection Systems

How Can I Use Rainwater?

Indoor Non-Drinkable

Next to outdoor uses, toilet flushing and laundering represent about 20-40% of water usage totaling 50,000 gallons annually for a family of four. In larger, multi-unit facilities such as university dorms, the savings is far more.  This water needs to meet certain water quality standards as outlined by the State of Georgia plumbing code. The recently updated standards require fine filtration and disinfection with UV light or chlorine for uses inside buildings.

The best time to install rainwater plumbing specifically for toilet flushing and laundry is when during construction or majorly remodeled since separate water lines are required. However, in some cases this may be able to be done in existing buildings as a retrofit.

Estimating the Costs and Benefits

ECOVIE can estimate the costs and benefits of using rainwater indoors. Typically, we will consider indoor applications after looking at outdoor water demands. NOTE: This type of project can be attractive financially since usage is year around and indoor usage does not fall under any type of usage restriction.

Combining rainwater harvesting with low flow fixtures

At Ecovie, we totally endorse and support the use of dual flush, low flow toilets and other fixtures inside the house.  in fact, the combination of using rainwater harvesting with low flow fixtures maximizes the amount of reduction in municipal water use and reduces the cost of a rainwater collection system.  As low flow toilets go, we recommend Caroma toilets because they use less water than the standard 1.6 gpf low flow toilets and have much better flushing ability, something we all know is important!

Using Graywater for Further Water Usage Reduction

Another alternative to consider when looking for ways to conserve your water usage is the capture and reuse of water from HVAC condensate, showers, and laundry (gray water) for outdoor irrigation and indoor non-potable uses (toilets flushing). The Georgia Plumbing Code now allows this practice and gives standards for its use.

ECOVIE will be delighted to install a graywater system to further increase your water self-sufficiency and cost savings.

OK, so rainwater and graywater make sense for indoor no-potable uses. Check out the next section to find out how rainwater harvesting can be better than city water for indoor potable uses!
