Retrofits and Remodels

Here’s why we usually only support new construction –

This is what greywater plumbing looks like coming out of the house before everything gets backfilled. An existing building's plumbing has none of that.

Greywater and sewer pipes about to be buried in new construction

#1. Greywater pipes can only be cost-effectively arranged during new construction.

  • Greywater sources are almost impossible to separate
  • Pipes in slab floors can’t be tapped without cutting the slab
  • Upstairs greywater is mixed with sewage before it descends
  • Laundry is far from showers, making it costly to use both
Most existing homes already have an irrigation system in their landscape. Whether sprinklers, rotors, micro spray, or drip, it's not underground drip approved for untreated greywater.

Unfortunately, sprinklers waste 25% – 60% of the water you purchased

#2. Most existing homes already have viable irrigation.

  • It’s not practical, easy, or legal to retrofit greywater into an existing irrigation system
  • Most people don’t want to buy another irrigation system if their existing irrigation already works
  • Established landscapes have to be torn up to install the underground drip irrigation required by law for greywater

#3. Retrofitting a greywater irrigation system requires numerous professionals.

  • You’ll need a plumber to retrofit the indoor plumbing
  • You’ll need a landscape contractor for the irrigation
  • You’ll need a licensed electrician to wire it safely
