GRAYWORKS GRAYWATER REUSE SYSTEMS

Graywater Reuse Systems:
Sustainable Water Solutions for Your Business

As the global demand for water continues to rise, businesses are looking for innovative ways to conserve resources and reduce costs. One of the most effective methods is graywater reuse—an eco-friendly solution that recycles gently used wastewater from sources like sinks, showers, and laundry machines. Rainwater Management Solutions (RMS) specializes in providing tailored graywater reuse systems that help businesses and institutions cut water usage, lower costs, and reduce their environmental impact.

Modular and Scalable Graywater Reuse

Rainwater Management Solutions specializes in helping businesses reuse graywater in the safest, most efficient and economical way possible. Once properly treated, graywater can be used for things like flushing toilets and irrigation purposes, reducing the strain on local water treatment plants, conserving freshwater, and helping you to save money in the process.

 

RMS prides itself on offering quality graywater reuse systems to each and every client through the innovative GRAYWORKS product line.

What is Graywater?

Graywater refers to wastewater that comes from sources such as bathroom sinks, showers, bathtubs, and laundry machines. Unlike blackwater, which contains sewage and requires more intensive treatment, graywater can be reused after undergoing specific filtration, disinfection, and biological treatment. This makes it an ideal candidate for non-potable uses like irrigation, toilet flushing, and cooling systems. With the right graywater system, businesses can reduce their reliance on municipal water, creating a more sustainable water management approach.

 

By repurposing graywater, companies not only reduce their environmental impact but also lower utility costs. With water scarcity on the rise, it's more important than ever to explore ways to reuse this valuable resource.

How Does a Graywater System Work?

A graywater system collects gently used wastewater from select sources within a building. Here’s how the process works:

 

  • Collection: Water draining from sinks, showers, and laundry facilities is captured through a separate plumbing system that directs it to a graywater treatment unit.
  • Screening: Lint and hair are removed directly through a self-cleaning screen and then flushed to the sewer. The screen can be mounted directly to the system or with a remote pump station depending on site requirements.
  • Biological Treatment: Pollutants are biologically degraded by microorganisms living on the patented surface-active treatment media creating a robust treatment that responds to variations in influent flow and quality.
  • Filtration & UV: Filtration removes suspended solids and Ultra Violet light disinfection eliminates any pathogens. The filtration system is self-cleaning and backflushes debris to the sewer. All equipment is secured within the cabinet.
  • Chlorine + Dye: Optional dye and chlorine systems can be included depending on project requirements. Dosing pumps, chemical storage, and spill containment are provided in the integral chemical cabinet.

 

The process is designed to be simple yet effective, allowing businesses to seamlessly integrate graywater reuse into their daily operations.

GRAYWORKS

Developed alongside Critical Flow, the GRAYWORKS product line has been instrumental in establishing the viability of decentralized graywater treatment/reuse and rainwater harvesting by integrating industry-leading biological treatment with a modular scalable design. The GRAYWORKS treatment and reuse product line was developed for all kinds of commercial establishments, including resorts, university dorms, corporate campuses, offices, multi-unit residences, and mixed-use developments. For our clients, the GRAYWORKS system reduces water use, saves money, and doesn’t break their budget or stress their facilities staff.

 

RMS is also capable of providing customary Graywater Reuse systems for commercial and industrial applications. The basic treatment train is utilized but can be tailored to fulfill specific requirements. The modular housing can be included or not, depending upon space allowance.

 

In addition, RMS offers a "Value Package" Graywater Reuse System for subsurface irrigation. Due to no human contact, a less intensive treatment is required and thus saves money.

Benefits of Graywater Reuse Systems

Graywater reuse systems provide a wide range of benefits, both environmental and economic. Here are some of the key advantages:

 

  1. Water Conservation: By reusing water that would otherwise go to waste, businesses can significantly reduce their water consumption.

  2. Cost Savings: Lower water consumption means reduced water bills. For businesses with high water usage—such as hotels, universities, and manufacturing facilities—graywater systems can lead to substantial financial savings over time.

  3. Environmental Impact: Reducing reliance on freshwater sources helps to alleviate pressure on local water supplies and ecosystems. It also reduces the energy required for water treatment and distribution, contributing to a lower carbon footprint.

  4. Sustainability Goals: Many businesses are adopting green practices as part of their corporate social responsibility. Implementing a graywater reuse system can help organizations achieve sustainability targets and enhance their reputation with environmentally conscious consumers and stakeholders.

 

BIOLOGICAL

All municipal and commercial wastewater reuse systems rely on biological treatment to remove dissolved pollutants but many graywater systems still utilize unreliable chemical treatment processes. GRAYWORKS incorporates a proven biological reactor design that efficiently removes dissolved organic materials and naturally responds to changes in flow and concentration.

MODULAR

The GRAYWORKS system is the first modular graywater system to incorporate all aspects of graywater treatment into a single unit that includes biological treatment, filtration, disinfection, project-specific polishing, and online instrumentation in a secure enclosure. The modular design significantly reduces installation costs.

SCALABLE

The GRAYWORKS product line is scalable to provide cost effective reuse across a wide range of sizes and applications. System design can incorporate project specific.

Graywater Reuse in Different Sectors

Graywater reuse is not a one-size-fits-all solution. Different industries have unique water needs, and RMS provides customizable systems for various sectors:

 

Hospitality: Hotels and resorts can benefit greatly from graywater systems by reusing water for laundry, irrigation, and toilet flushing. This reduces operational costs while maintaining guest comfort.

 

Educational Institutions: College campuses are ideal for graywater systems due to the high water usage in dormitories, dining halls, and athletic facilities. Graywater can be repurposed for landscaping and non-potable applications, helping schools achieve sustainability goals.

 

Agriculture: In regions facing water scarcity, graywater systems allow farmers to use treated water for drip irrigation, ensuring consistent crop production even during droughts. This helps conserve potable water for essential uses while maintaining healthy yields.

Frequently Asked Questions (FAQ) About Graywater Reuse Systems

What is graywater, and how is it different from blackwater?

Graywater is the gently used wastewater from sinks, showers, and laundry machines, while blackwater comes from toilets and kitchen sinks. Unlike blackwater, graywater can be treated and reused for non-potable purposes such as irrigation and toilet flushing.

Is graywater safe to reuse?

Yes, once treated, graywater is safe for non-potable uses like irrigation and toilet flushing. Treatment processes such as biological treatment, filtration, and UV disinfection help to remove harmful pathogens.

What are the benefits of installing a graywater reuse system?

Graywater reuse systems conserve water, lower utility bills, and reduce strain on local water treatment facilities.

Can graywater be used for irrigation?

Yes, graywater is commonly reused for landscape irrigation, as long as it has been properly treated to remove harmful contaminants. This helps reduce the demand for freshwater in landscaping. While general landscape irrigation using graywater can be either spray or drip, agricultural crops irrigated with graywater must use drip irrigation.

Are graywater systems suitable for all businesses?

Most businesses that generate graywater from sources like showers, sinks, and laundry can benefit from a graywater reuse system. Industries such as hospitality, agriculture, and commercial offices are particularly well-suited for these systems.
