Calculation Methodology & Assumptions
This calculator provides estimates for planning purposes only. Actual costs vary based on project-specific factors including site access, local labor rates, equipment requirements, and regional pricing.
Traditional 2D Weep Hole Assumptions
- Installation time: 4-6 hours per opening (includes forming, pipe placement, aggregate, and finishing)
- Maintenance time: 2-4 hours per opening per visit (clearing, flushing, inspection)
- Material cost: ~$50 per opening (pipe, aggregate, geotextile)
- No filtration: Subject to frequent clogging from sediment and debris
JET Filter™ Assumptions
- Installation time: 30 seconds per unit (press-fit into existing opening)
- Maintenance time: 5 minutes per unit (visual inspection, cartridge check)
- Maintenance interval: 3-5 years (3″), 4-7 years (4″), 6-10 years (6″) based on soil conditions
- Cartridge replacement: Estimated 1 replacement per unit over 10-year period
- Product pricing: Ranges shown reflect typical market pricing; contact us for project-specific quotes
Data Sources
Flow rates and performance data from TRI Environmental Report MAPP-LSH 2020-003. Maintenance intervals based on field performance across 15+ state DOT installations. Installation times based on contractor feedback and case study documentation.
*Soil condition affects maintenance frequency. Silty sand environments require more frequent inspection due to higher sediment loading. Clean water applications may exceed stated maintenance intervals. Results do not include traffic control, lane closure costs, or emergency repair scenarios which may significantly increase traditional 2D weep hole lifecycle costs.
