About National Wastewater Systems Systems
National Wastewater Systems manufactures aerobic treatment units for both residential and commercial applications in Texas. With 8 TCEQ-approved models, they offer a range of capacities for different property sizes. Their systems are installed throughout Harris County and the greater Houston area.
TCEQ-Approved National Wastewater Systems Models
National Wastewater Systems offers TCEQ-approved models from 500 to 1,500 GPD covering residential homes from 2 bedrooms up to larger properties and light commercial installations.
Common National Wastewater Systems Maintenance & Repair Issues
Standard aerobic system maintenance applies — aerator servicing, chlorinator maintenance, spray head inspection, effluent quality checks, and electrical component testing. Our technicians approach National Wastewater Systems units with the same thorough inspection protocol used for all aerobic brands.
Our National Wastewater Systems Maintenance Services
Full TCEQ-compliant maintenance services are available for all National Wastewater Systems models, including the three-times-per-year inspection schedule, county reporting, and 24/7 auto-dialer monitoring through our maintenance contracts.
Harris County Auto-Dialer Requirement
Harris County now requires cellular auto-dialer monitoring devices on all aerobic septic systems, including National Wastewater Systems units. When your system triggers an alarm — high water, pump failure, aerator malfunction, or power loss — the dialer alerts our office immediately, and we are required to respond within 72 hours. Our maintenance contracts include 24/7 auto-dialer monitoring at no additional charge.
If your National Wastewater Systems system does not yet have an auto-dialer installed, we can install an RMSYS RMS-812 cellular monitoring device during a maintenance visit. The installation is $750 (hardware + labor), and the monitoring service is included in your maintenance contract.
National Wastewater Systems Maintenance Contract Pricing
All National Wastewater Systems aerobic systems require TCEQ-mandated maintenance every four months at minimum — Harris County requires inspections every three months (quarterly). Our maintenance contracts cover everything: inspections, county compliance reporting, 24/7 auto-dialer monitoring, and 72-hour alarm response.
