Overview

Mission

The mwm owns and operates the waterworks museum (the "museum"), including a community meeting room. The museum is a single condominium unit of the museum building condominium, one of separate condominium building regimes on the site. The four buildings share certain operating responsibilities through an administrative trust (the waterworks at chestnut hill trust), and the complex is commonly known as the waterworks at chestnut hill. The site was previously the chestnut hill waterworks, owned by the commonwealth of Massachusetts, and disposed of in accordance with the lda. Three of the four buildings and the adjacent chestnut hill reservoir are listed on the national register of historic places and the entire site is a designated city of boston landmark. The museum houses three historic steam pumping engines installed between 1894 and 1921: the allis, the worthington, and the leavitt. As required under the lda, mwm provides public access to the museum at no fee, and to the community roo

What it reported doing in 2025

The museum houses three historic steam pumping engines installed between 1894 and 1921: the allis, the worthington, and the leavitt. The mwm provides public access to the museum at no fee, and to the community room at a marginal cost recovery charge, both in perpetuity. Its mission as an educational non-profit is to promote learning at the waterworks museum, as well as preserving the magnificent industrial archaeology of the building and engines.

Operating model

Revenue model
Donor-supported. 97% of the money available for current operations came from contributions and gifts.
Distribution model
Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.

The verdict

STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. Expenses are high relative to revenue and assets have declined or grown slowly.
