SDG: 6

This solution caters to local governments that have the mandate to manage stormwater in a city. It addresses the management of rainfall and runoff from public open spaces and transport infrastructure. The management of runoff from residential, commercial and institutional buildings are covered in a separate Solution as a different approach is required for areas under private ownership.

This Solution is tailored to Local Governments who have ownership and/or regulatory authority over the municipal water supply system. In this Solution, the Local Government takes a comprehensive approach to increase its energy-efficiency throughout the different phases of the system`s project and useful life, from policy setting, planning, project design, and project evaluation to operation, maintenance and monitoring.

Water is a vital, limited and variable resource which is under increasing demand. Integrated Water Resources Management (IWRM) (glossary) is a process which seeks to secure access to clean water, to satisfy current and future needs, in an economically efficient, equitable, and environmentally sustainable way. It includes: good governance principles and taking advantage of scientific knowledge to support policy and decision-making; coordination of the different LG departments and engagement of a wide range of stakeholders; integration of different water uses within the watershed, upstream and downstream (including with wastewater management); the integration of future needs into current planning processes; and as a next generation of integration the water – energy nexus. This Solution focuses on the processes which the Local Governments (LGs) can implement to contribute to IWRM, within their territory and beyond.

Over 80% of Local Governments (LGs) worldwide are responsible for residential solid waste collection within their territory [1]. However, solid waste management is a great challenge from an organizational, technical, and financial perspective, and municipalities are often overburdened by the task. This solution focuses on the processes which the LGs can undertake to promote sustainable waste management in their communities through a long-term approach.

The Local Government implements a set of integrated measures to deploy solar hot water in private buildings and facilities in the community within its jurisdiction. The local government uses its regulatory power as the main leverage to approve or amend a municipal building code that requires (new) buildings to use solar hot water (SHW) systems – Solar Ordinance.

Solar water heaters use solar energy to heat water. In this Solution, the Local Government takes leadership. It acts as a role model for the community by implementing measures to deliver solar hot water (SHW) systems in government buildings and facilities it owns and/or operates.

This solution is tailored to local governments that have a mandate to approve and enforce municipal building regulations or bylaws that require and/or incentivize the use of SUDS and rain water harvest in private buildings and facilities in the city. It is applicable to new settlements as well as existing residential, commercial and institutional buildings and facilities.
