Legislation allowing sub-metering
In December 2004, Chapter 417 of the Acts of 2004, An Act Authorizing Water Sub-Metering in Residential Tenancies, was signed into law and became effective March 16, 2005. The new law allows landlords to install sub-meters for residential tenants and to bill tenants for water and sewer use. MassDEP supports sub-metering as a means to promote water conservation.
While the new law does not directly affect public water suppliers, systems should be aware of it and may receive calls regarding meter installation and bill payment. Landlords should be reminded that they are still responsible for payment of the water and sewer bills. The master water meter at any building remains under the jurisdiction of the public water supplier. Water suppliers should also work closely with local plumbing inspectors to insure installations meet all legal requirements. - Testing Requirements for Public Water Systems - Summary
