Graywater system cost and available rebates

The amount really depends on site-specific conditions, but in general, a laundry-to-landscape system installed by a contractor will cost between $1,500-$3,000 (the material cost is typically covered by the rebate amount). All other graywater systems increase in complexity, cost, and regulatory hurdles: a whole-house graywater system may cost upwards of $15,000 excluding permitting costs and backflow-protection requirements.
