Township Council through consultation with the Rideau Valley Conservation Authority and the Planning Advisory Committee had previously adopted an annual lake-by-lake schedule to guide the Septic Reinspection Program in the years 2007-2015 through a voluntary approach. This schedule was intended to ensure that all lakes were inspected in the Township while ensuring that the inspections were accomplished in an efficient and cost-effective manner. Lakes inspected include: Bass, Bellamy, Lower Beverley, Upper Beverley, Clear/ Indian/ Benson/ Mosquito, Crosby, Little Crosby, Mill, Newboro/ Loon, Opinicon, Otter, Pike, Big Rideau, Sand, Troy, Whitefish and Wolfe.
Since 2015, Township Council has implemented a hybrid approach to the septic program which includes 100 mandatory inspections and up to 50 voluntary inspections annually. The mandatory program is completed by the Mississippi Rideau Septic System Office and the voluntary program is completed by the Development Services Department at the Township. The lakes chosen to participate through this program are chosen by Council Resolution annually.
- 2018: Upper Rideau Lake and Lower Rideau Lake
