Optional Fields

A brief description of the institution's water-related behavior change initiatives:

Efficient and rational use of water: we have three sources of water supply: municipal aqueduct, rainwater and surface water. For the latter, the PUEYRA (Program for the efficient and rational use of water) was developed through which consumption goals are established for the five-year period 2020-2024, the year up to which it is expected to achieve savings of 20%. This saving is established from the baseline established by the environmental authority, which is 0.64 L/s.

A brief description of the institution's water recovery and reuse initiatives:

At the university, rainwater is recovered for discharge from sanitary systems

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

The university has systems that save water consumption
