Low impact development (LID) rainwater management programs are designed to manage stormwater close to its source by mimicking a site's pre-development hydrology through the use of design techniques that infiltrate, filter, store, evaporate, and detain runoff close to its source. Treatment and potential reuse of rainfall on-site is a key result of such programs, aiming to reduce runoff volume and improve water quality.
References: The LEED v4.1 O+M reference materials discuss the integration of green infrastructure and low-impact development strategies with the Rainwater Management Credit, which includes on-site treatment and reuse of rainwater1234.

The Sustainable Sites Credit, Site Management in LEED AP Operations + Maintenance (LEED AP O+M) V4.1 includes the requirement of instituting a policy to prevent erosion and sedimentation and restore any eroding soils. This is part of the broader strategy to manage the site in a sustainable and environmentally friendly manner.

To achieve the Water Metering Credit, the project must track all water meters on a weekly basis and share this data with the USGBC for a duration of five years starting from the date the project receives LEED certification.
References: The LEED v4.1 O+M guide specifies that for the Water Metering Credit, meter readings must be documented weekly and submitted to USGBC for a five-year period post-certification12.
To achieve the Water Metering Credit, it's necessary for all water meters to be monitored on a weekly basis, with the data being shared with the USGBC for a duration of five years starting from when the project officially accepts its LEED certification. This rigorous monitoring ensures that the project maintains a high level of water efficiency and accountability post-certification, contributing to sustainable water management practices.
References:This requirement is outlined in the LEED AP Operations + Maintenance reference materials, specifically within the section detailing the Water Metering Credit. These documents emphasize the importance of consistent and transparent water usage monitoring as part of sustainable building operations.
