Grey wa­ter don’ts

Home (South Africa) - - GARDENS WATERWISE -

• Grey wa­ter tends to clog pop-up or mi­cro­jet sprin­klers – when wa­ter­ing with grey wa­ter, rather use a gar­den hose. Al­ter­na­tively, in­stall a fil­ter in your ex­ist­ing au­to­matic ir­ri­ga­tion sys­tem.

• Don’t pour grey wa­ter into the toi­let tank for flush­ing as there’s a slim chance that it could be back-si­phoned into your fresh wa­ter sup­ply. Pour the grey wa­ter into the toi­let bowl in­stead.

• Wa­ter­ing your herbs and veg­eta­bles with grey wa­ter is not rec­om­mended.

• Laun­dry wa­ter in which nap­pies or other items that pos­si­bly con­tain urine or fae­ces have been washed should not be reused.

• Grey wa­ter should not pool on top of soil; it will pro­vide a breed­ing ground for mos­qui­toes.

• Chil­dren and pets should not drink or play in grey wa­ter. >>
