Septic Services in Dickinson, TX
Dickinson homeowners pay $235-$350 for standard septic pumping, with most 1,000-gallon tanks costing around $275. Post-hurricane emergency service runs $400-$700.
Dickinson sits in Galveston County between Houston and the Gulf Coast, with a population of about 22,000 residents. The city's location brings unique challenges for septic systems: high water tables, coastal clay soils, Dickinson Bayou running through the heart of town, and hurricane exposure that can stress or damage systems for miles inland.
If you own a home on septic in Dickinson, you're dealing with environmental conditions that require specialized system design and maintenance. The EPA estimates that over 2 million U.S. septic systems fail annually, and coastal areas like Dickinson face higher risk due to water table and soil challenges. The good news is that local providers understand these conditions and know how to keep systems functioning reliably in coastal terrain.
What Septic Services Are Available in Dickinson?
Dickinson providers offer pumping ($235-$350), installation ($6,300-$12,000), repair ($400-$4,000), and inspections ($300-$500), all adapted for coastal conditions.
Dickinson's coastal location shapes every aspect of septic service, from system design to maintenance schedules.
Septic Pumping
Most Dickinson households should pump every 3-5 years, though the high water table and flood exposure in many areas may warrant more frequent service. If your property floods during heavy rain or storm surge, schedule a post-event inspection and pumping to remove any infiltrated water and verify system integrity. Regular pumping is especially critical here because saturated soils already stress drain field performance.
New System Installation
New septic installations in Dickinson must account for high water tables that can limit conventional system viability. A conventional system runs $6,300-$7,500 when soil conditions allow, but many properties require aerobic systems at $7,800-$9,800 or drip systems at $9,800-$12,000. Galveston County Health District reviews all designs and requires site-specific engineering for properties near Dickinson Bayou or in flood-prone areas.
Septic Repair
Coastal conditions accelerate wear on septic components. Saltwater intrusion, storm debris, and saturated soils all contribute to system stress. Common repairs include pump replacements, tank lid repairs, and drain field issues caused by water table fluctuations. Repair costs range from $400 to $4,000 depending on the problem, with drain field work at the higher end.
Septic Inspection
Buying or selling in Dickinson? Inspections run $300-$500 for thorough assessment, with combined pumping-and-inspection packages at $450-$650. Given the coastal environment, inspectors pay close attention to flood damage history, water table conditions, and system elevation relative to seasonal high water levels.
Aerobic System Maintenance
Aerobic systems are common in Dickinson because many properties have soil conditions that don't support conventional drain fields. TCEQ requires inspections every four months for aerobic systems. Galveston County Health District recently increased maintenance agreement fees to $125 (effective January 2026). Budget $500-$700 every two years for maintenance contracts.
What Makes Dickinson Different for Septic Systems?
Coastal Clay Soils and High Water Tables
The soils underlying Dickinson are a mix of fine sands and clay, with seasonal water tables ranging from 11 to 32 inches below the surface. That's not much buffer between your drain field and groundwater, especially during wet months.
Galveston series soils drain moderately well in the upper sandy layers, but underlying clay restricts deeper percolation. During wet seasons, the water table rises close to the surface, reducing the treatment zone available for your wastewater. When the soil is saturated, wastewater can't percolate downward properly, leading to system backups or surfacing.
Many Dickinson properties require alternative systems designed for these conditions. Aerobic treatment units produce higher-quality treated water that requires less soil treatment. Mound systems build up treatment material above natural ground level. Low-pressure dosing systems distribute treated wastewater more evenly across the available absorption area.
Dickinson Bayou Watershed
Dickinson Bayou runs through the heart of the community, eventually joining Dickinson Bay and Galveston Bay. The watershed encompasses about 100 square miles, and an estimated 5,000 septic systems operate within it. According to the Dickinson Bayou Watershed Partnership (a Texas A&M AgriLife Extension project), roughly 3,700 of these systems experience some degree of failure at certain times of year due to the challenging soil and water table conditions.
The bayou has been listed as impaired for bacteria since 1996 per TCEQ water quality assessments. Failing septic systems are identified as a primary contributor to this contamination, along with stormwater runoff. As Nathan Glavy, a TWRI Extension program specialist at Texas A&M AgriLife Extension Service, notes, "Inspecting and maintaining septic systems can help prevent negative impacts on local water quality and public health." This water quality concern drives regulatory emphasis on proper septic design, installation, and maintenance throughout the Dickinson area.
If your property is near Dickinson Bayou or its tributaries, expect careful scrutiny of your septic system during any permitting process. The health district takes compliance seriously to protect water quality.
Hurricane and Flood Zone Considerations
Dickinson's location on the Gulf Coast means hurricane exposure is a reality. Hurricane Harvey in August 2017 brought catastrophic flooding that damaged thousands of homes and stressed septic systems throughout the area.
Flooding creates specific problems for septic systems:
- Saturated drain fields can't absorb wastewater, causing backups
- Improperly secured tanks can shift, float, or crack
- Power outages disable pumps in aerobic and pressure-dosed systems
- Floodwater can infiltrate tanks, overwhelming capacity
- Storm surge can contaminate systems with saltwater
Before hurricane season each year, consider having your tank pumped if it's been more than two years. A tank at capacity has no room to absorb floodwater infiltration. After any significant flooding, have your system inspected before resuming normal use.
About 6.8 percent of Dickinson properties currently have measurable flood risk, with that percentage projected to increase. If your property is in a flood zone, work with a provider who understands how to design, maintain, and recover systems for coastal flood conditions.
Galveston County Health District Permitting
Galveston County Health District administers all septic permits through its Environmental and Consumer Health Division. As of January 2026, residential permit fees are $310 (including the $10 state charge). Re-inspection fees are $150 if initial inspections find problems requiring correction.
The permit process requires:
- Completed application and site evaluation form
- Site evaluation by a licensed evaluator
- System design appropriate for your soil and water table conditions
- Inspections at construction milestones
- License to operate upon final approval
For alternative systems, you'll need variance approval at $150 and a two-year maintenance contract before the system can operate. Homeowners who complete approved 8-hour maintenance training courses may maintain their own aerobic systems after the initial two-year contract period.
Properties in the Bolivar or Galveston areas near particularly high groundwater conditions face a $100 groundwater review fee.

Frequently Asked Questions About Septic Services in Dickinson
How much does septic pumping cost in Dickinson?
Standard septic pumping in Dickinson costs $235-$350 for a 1,000-gallon tank, with most homeowners paying around $275. Larger 1,500-gallon tanks run $350-$500. Emergency and after-hours calls, especially after flooding events, can run $400-$700. These prices align with Houston-area averages, though post-storm emergency services may be higher due to demand.
How does the high water table affect my septic system?
Dickinson's seasonal water table ranges from 11 to 32 inches below the surface, which limits the soil depth available for wastewater treatment. When groundwater rises during wet periods, your drain field has less room to work. Wastewater can't percolate downward properly, leading to backups or surfacing in your yard. Many Dickinson properties need aerobic or other alternative systems designed for these conditions.
What should I do if my septic system floods?
Stop using water immediately and call a licensed provider for inspection before resuming use. Floodwater can infiltrate your tank, damage components, and contaminate your drain field. Don't pump a flooded tank while the ground is still saturated, as the empty tank might float or shift. Wait until floodwaters recede and the ground stabilizes, then have a professional assess the situation. Document any damage for insurance purposes.
Who handles septic permits in Galveston County?
Galveston County Health District Environmental and Consumer Health Division handles all septic permits. Residential permits cost $310 as of January 2026. You'll need a site evaluation, system design, and inspections before receiving a license to operate. The district coordinates with other agencies for properties near sensitive coastal resources. Properties requiring alternative systems need variance approval at $150 and mandatory maintenance contracts.
Do I need an aerobic system in Dickinson?
Many Dickinson properties require aerobic systems because seasonal water tables (11-32 inches deep) limit conventional drain field performance. Your site evaluation determines whether conventional systems will work on your property. If the soil can't provide enough treatment depth above the water table, Galveston County Health District will require an aerobic or alternative system. Aerobic systems cost $7,800-$12,000 to install and need inspections every four months per TCEQ rules.
