Lowell, Massachusetts landlords hold some of the most thoroughly master-metered housing stock in the country: triple-deckers, two-families, and converted mill buildings, nearly all plumbed with a single meter serving the whole property. Combine that with New England water and sewer rates, which run among the highest anywhere and keep climbing, and every gallon a tenant runs lands on the owner’s bill. Water submetering changes the arithmetic by putting a meter on each unit, so tenants can be billed for the water they actually use. Lowell’s rental base is heavily individual owners leasing to UMass Lowell students and working families, tenants who move often and have no visibility into what water costs. True Submeter handles the metering and the monthly invoicing automatically. Usage falls once it carries a price, the guesswork in splitting a bill disappears, and net operating income improves. Massachusetts sets specific requirements for billing tenants this way, so confirm what applies to your building first.
