Don't forget to participate in the District of Sparwood's Toilet Rebate Program. All you have to do is replace an existing 13L or greater toilet with an eligable low-flow model.
Not sure what low-flow toilet to buy? Use the Veritec and Koeller report on the Maximum Performance (MaP) of over 1,000 different toilet models. In the spreadsheet, the models with a MaP value of 1000 are considered the best.
More information and an application form are available here.
