Efforts to address these challenges are compounded by policy discontinuities that result from a change in the majority of the municipal administration every three years. The region’s transport network is characterised by congested highways and poorly maintained urban roads. As to water and wastewater management, in spite of the high coverage of water and sanitation in the Puebla-Tlaxcala metropolitan zone (reported at 87% and 96%, respectively [SEDESOL, 2012]), the frequency of water provision and quality of infrastructure remain inadequate.
