Columbia Water GIS Relocates to Washington Square Columbia Water’s Geographic Information Systems (GIS) team led by Stewart Hall recently relocated from the Clean Water 2020 (CW2020) program office to the City of Columbia’s offices at Washington Square. Staff was originally a GIS Technician and a GIS Manager under the Sewer Mapping Plan (SMP), the City’s effort to establish the current wastewater collection and transmission system (WCTS) asset data and electronic systems to be used with other programs required in the Consent Decree (CD). However, Columbia Water proactively expanded GIS staffing to one Manager and six Technicians. For 9 years the GIS team was embedded in CW2020 to work directly with program leads on CD goals. The CD requires improvement to the City’s WCTS GIS data sets, mapping standards, and integration with other systems such as Cityworks. Since implementation of the CD began, the GIS team has also expanded duties to improve water and stormwater GIS standards. The team recently completed their required goals of accurately mapping the WCTS system and continue to improve water and stormwater GIS accuracy through survey, inspection, and integration with other information systems.
Mapping Technician Manager Stewart Hall has been with the City of Columbia for 11 years. Previously with the City’s IT GIS Department, Hall transitioned to his current role managing the Columbia Water GIS team in 2019. Through meticulous recruitment, Hall has brought together a team of mapping technicians from various backgrounds to support the City’s GIS needs. Mapping Technician Lead Matt Naglak has a BS
from the University of Arkansas, a PhD in Digital Archaeology from the University of Michigan, and over 10 years’ experience in archaeological and digital mapping projects. Senior Mapping Technician Martin Rivas has extensive experience with wastewater assessment in both the private and public sectors. The most recent additions are Mapping Technician Senior Felix Mitchell and Mapping Technicians Michael Wagner and Hannah Harp. All three are graduates from the University of South Carolina (USC). Mitchell’s time at USC was spent developing skills through several GIS-related positions. Harp graduated with leadership distinction with a degree in Marine Science. Wagner brings along a year of field experience with Water Maintenance along with a BA in Environmental Studies. The GIS team maintains a database for the City of Columbia that includes digital mapping layers for the WCTS (e.g., gravity mains and manholes), Water Distribution, (e.g., water mains and laterals, and fire hydrants), and Stormwater Collection (e.g., stormwater pipes, channels, catch basins) as well as mapping layers and tables used for detailed analysis on areas such as capacity planning, sanitary sewer overflows, capital improvement projects, asset risk, and water service line inventory. The database is used citywide to provide accurate data to citizens, staff, maintenance crews, leadership, and decision makers. Columbia Water crews and contractors may link to the data while working in the field to access info on prior repairs or locate system assets.
Demystifying Compost You might wonder, “What is compost?” or ask, “Why should I consider composting?” Let us help explain what it is and the benefits of composting. Composting is a process that converts organic materials (i.e., wasted food scraps and yard debris) into a nutrient-rich soil amendment or mulch through natural decomposition. Macro organisms like worms and insects and microorganisms like bacteria and fungi feed on our waste materials and do all the hard work to create a dark, crumbly, earthy-smelling material known as compost. Composting is nature’s way of recycling. By composting, you sustainably reduce the amount of trash you send to the landfill or incinerators. In turn, you prevent additional greenhouse gases being sent into the atmosphere. Not only does it build healthier soil, prevent erosion, and help you conserve water, but it also improves plant growth in your garden and yard. And the big bonus you don’t want to miss is it can save you money by reducing your use of fertilizer and pesticides and decreases the chance of excess chemicals getting into our water. In a few easy steps you can use a bin, bucket, or even a pile to start. Combine two parts browns to every one part green,

keep things moist, and occasionally turn the materials to add air. Browns and greens are easily identified by their name. Browns include things like dry leaves and yard trimmings (brown in color) and greens are things like food scraps and grass clippings (greener in color). Something to always remember is to never add meat, dairy, or greasy foods to your pile. These will attract unwanted pests. As waste decomposes, you reap the benefits. Add finished compost to your soil to improve the health of your soil, help the soil retain moisture and nutrients, attract beneficial organisms to the soil, and reduce the need for pesticides and fertilizers.
