Gray water from laundry is probably best oriented toward an area with various salt tolerant species of trees, shrubs, and groundcover. There are books on Greywater design by Art Ludwig and Brad Lancaster that show detailed diagrams for building such a system.(pipe dumps into a mulch filled ditch next to woodlands)

Installing a perforated pipe close to street trees can be fitted with a dripper for deeper penetration but also allow for aeration, fertilization, and simplify flood watering with a hose. Generally most important in clay soils.
In sandy soils subsurface irrigation should be fine.
Also utilizing pavers instead of concrete within range of the pro…[Read more]
I prefer the subsurface irrigation(Netafim) that Doug referred to. It’s expensive to install per square foot but you can’t beat the water efficiency. These systems need a pressure regulator(35-50psi) and filter post cylenoid. Netafim stands out in subsurface irrigation because the emitters are self-flushing and clog resistant. I like to put bet…[Read more]
Just a thought from Soil Science perspective on reducing the water requirements for any plant. Use lots of organic material and or peat moss around the plant,(not too much) and surround other areas with sand. Make sure the drip is going on the water holding material. Sand has the lowest affinity for water while clay has the highest and organic…[Read more]
