All our grey water goes on the garden including the kitchen waste.
Plants thrive on a bit of extra phosphtes from the detergents. That's
the problem with detergents running into watercourses - they produce
algal blooms. Can't use it if there's a hose pipe ban? If that's the
law the law is an ass. We havn't got mains drainage anyway so the
water company can't have it back! Our black water irrigates the land
as well but after its been through a septic tank and a reed bed.
