Description: Wastewater manholes are a point feature class in GIS, representing access points to underground sewer systems. Cities use GIS to map locations and manage attributes like depth, material, and condition. Data is collected using NASSCO’s Manhole Assessment Certification Program (MACP) standards to ensure consistent, high-quality inspections. MACP defines how to document defects and structural conditions, enabling reliable data integration into GIS. This supports asset management, maintenance planning, and regulatory compliance. By combining GIS with NASSCO standards, cities can efficiently prioritize repairs, estimate costs, and maintain the long-term performance of their wastewater infrastructure.
