Sanitary Sewer Planning and Modeling

• Master planning for sewer extensions

• Evaluation of monitoring data for dry weather flow and inflow/infiltration

• Modeling sewer hydraulics with EPA-SWMM or similar programs

• Analysis of population data to estimate sewer loadings

• Projecting future needs and designing phased-in projects to meet those needs

City of Ada - Sanitary Sewer Inflow/Infiltration and Rehabilitation Studies

• Planned and conducted a long-term monitoring study at several locations in system 
• Used monitoring results to determine average and peak dry weather flows 
• Used monitoring results to determine amount of infiltration and areas most prone to infiltration 
• Correlated with rainfall data to evaluate impact of various amounts of rainfall on system

City of Stillwater Sanitary Sewer Model

• Build a computer model of the Stillwater System for use by city employees to evaluate impact of proposed development
• Researched capabilities/costs of various public domain and vendor-provided models
• Selected SWMM-EXTRAN (XP software version) due to presence of backwater effects, pressure flow, and possible looping
• Researched plans filed with city
• Supplemented data and reconciled discrepancies using GPS and conventional surveying
• Estimated system loadings based on census block data - only monitored flow data available was at wastewater treatment plan
• Adjusted model so that overall system flows agreed with measured flows
• Model is still being used to assess requests from developers to tie into sanitary sewers
