Drinking Water Systems Regulation
O.Reg. 170/03
(Regulation made under the Safe
Drinking Water Act, 2002)
The Drinking Water Systems Regulation (O. Reg. 170/03) regulates municipal
and private water systems that provide water to year-round residential
developments and designated facilities that serve vulnerable populations
such as children and the elderly. Designated facilities include children’s
camps, child and youth care facilities, health care and social care facilities,
a school or private school, a social care facility, a university, college
or institution with authority to grant degrees.
Amendments to O. Reg. 170/03 came into effect on June 5, 2006. The amendments
are risk-based and are designed to safeguard the quality of Ontario’s
drinking water, while making the regulation more workable and affordable
for residential drinking water systems and systems serving designated
facilities. They add clarity and flexibility to the testing and operational
regimes set out in Reg. 170 and in some cases, could reduce the cost of
regulatory compliance.
O. Reg. 170/03 does not apply to non-residential and private seasonal
residential drinking water systems unless they serve designated facilities.
These systems are regulated by the new regulation for non-residential
and private seasonal residential systems that do not serve designated
facilities (O. Reg. 252/05) (http://www.ene.gov.on.ca/envision/water/sdwa/reg252.htm)
