• HomeGuide's published national pump-out range is $300 to $700, based on $0.30 to $0.70 per gallon of tank size.
• HomeGuide lists an inspection at $150 to $450, which buyers in flood-prone parts of the county often order before closing.
• State fee: Texas Health and Safety Code Chapter 367 adds a $10 TCEQ fee to each OSSF permit, collected by the local permitting authority.
• Method: HomeGuide's per-gallon range scaled to your tank size, plus county and state permit fees for repairs. Aerobic units add contract costs, and disposal or haul distance from the river bottoms raises the local price.

• Step 1, permit first: Brazoria County says an OSSF permit is required before installation and before a building permit, and an existing system without a permit can't be permitted after the fact.
• Step 2, design: the application package needs a site evaluation by a professional engineer or licensed site evaluator and a design by a registered sanitarian or engineer under 30 TAC §285.5.
• Step 3, review and fee: the county says at least two Designated Representatives review each application, and fees are due only after approval, when the Authorization to Construct is issued. Texas statute adds a $10 TCEQ fee per permit.
• Step 4, maintenance: where 30 TAC Chapter 285 requires one, a maintenance contract goes in with the application, and installers and maintenance providers must register with the county.
• Step 5, large tracts: the county says it exempts a single-family home on one tract of 10 acres or more if every part of the system is at least 100 feet inside the property lines.

• Coastal clay: heavy clay soils along the Brazos and San Bernard river bottoms and across the coastal prairie south of Alvin absorb effluent slowly, which is why aerobic spray systems are common.
• USDA NRCS soil survey data rate 75.2% of Brazoria County (TX039) as very limited for septic tank absorption fields.
• Flooding: OpenFEMA lists 7 flood and 6 hurricane declarations among the county's 24 major disasters, and floodwater can fill tanks and drainfields near the rivers.
• High water table: the flat terrain near the coast and along Chocolate Bayou keeps the water table close to the surface in wet months.
• Census ACS counts about 150,321 housing units with a median year built of 1996.
