We are a licensed engineering firm in Texas that provides design and consulting services for graywater reuse systems on residential and commercial projects. Graywater reuse systems have specific regulations dictated by your local municipality or county.
Due to the fact that graywater systems are part of the plumbing system for a house or building, it is imperative that these systems be designed properly and inline with current code. Not only that but these systems can become a maintenance nightmare if not designed properly. We have the expertise and experience to provide full design and installation capabilities.
Who uses this service?
- Homeowners who don’t know where to start so you would like a documented system plan for either your use or to provide to other contractors to solicit bids (great option if you are not located in central Texas where IWS can design AND build your system for you).
- Homeowners who are building a new house and want to ensure the proper system integration into your house/property.
- Architects and Engineers who have been asked to incorporate a graywater recovery system into your project.
- Homebuilders or Contractors who have clients that want to install a graywater reuse system but there aren’t any construction plans or the existing plans leave a lot of questions.
Benefits of using a licensed design professional
1. Design Liability (who is responsible for system design failures if you use a non-licensed design professional?)
2. Knowledgeable resource of local regulations related to graywater system implementation
3. Opportunity to determine any obstacles prior to construction
4. System optimization according to the desired water conservation goals
5. Creation of realistic budget for the designed system (why put time and effort into designing a system just to have it value engineered out of the project because a realistic system budget wasn’t created?)
Graywater Reuse Systems for Residential Projects
Graywater reuse systems can provide auxiliary water on residential projects.
- To supplement or replace municipal water use in the irrigation system
- To distribute graywater around your house foundation in areas of high clay soils and a seasonal rainfall pattern
- To supplement or replace the use of municipal water for indoor, non-potable uses such as toilet flushing (in Texas)
One of the key obstacles to the implementation of a graywater reuse system in a residential project is the adaptation of the house plumbing to allow for the collection of graywater separately.
These design packages are intended to streamline the system design process and provide you with plans that fit your situation. With these plans, you can now have design documents that you can use to implement the system or you can provide to your contractor or home builder for them to install the system so that everyone to be on the same page.
For the custom design package, you must provide a pdf or cad version of your home plan and/or property plat.

Graywater Reuse Systems for Commercial Projects
Graywater reuse systems can provide auxiliary water for many different opportunities on commercial projects.
- To supplement or replace municipal water use in the irrigation system
- To supplement or replace the use of municipal water for toilet and urinal flushing
- To supply auxiliary water for internal building processes that do not require a municipally treated water source
The difficulty is in integrating the graywater reuse system into your commercial project so that it can efficiently provide the desired result. Many times there are many sources of graywater inside a commercial building and this may pose a problem in terms of quantity of graywater both in the treatment process and in using this water.
These design packages are intended to streamline the system design process and provide you with plans that fit your situation. With these plans, you can now have design documents that you can use to implement the system or you can provide to your contractor or home builder for them to install the system so that everyone to be on the same page.
These prices apply to most projects but depending on the complexity of the system, we reserve the right to provide an individual proposal for your system design.
