Septic System Design in the Houston Area
A septic system only works as well as its design. We design custom septic systems for homes and commercial properties across Harris, Montgomery, Waller, Fort Bend and San Jacinto counties, sized to your property and ready for permit approval.
Overview
Septic system design
01Designed for your property, not copied from another
Every property is different. Soil type, how quickly the ground absorbs water, groundwater depth, slope, trees, setbacks from wells and property lines, and how much wastewater you produce all decide what will work. Our team assesses these conditions and recommends a system that matches your needs and your budget.
02What a septic design includes
- Site and soil evaluation to learn what your lot can support
- System selection: conventional, aerobic with drip, or aerobic with spray distribution
- Sizing based on the home or business and its daily wastewater flow
- Layout drawings showing tank, treatment unit and drainfield or dispersal area
- Documents prepared for permit submission to your county or authorized agent
03Residential and commercial septic design
We design systems for single-family homes, small businesses and larger commercial properties. Commercial projects are sized differently from homes, so we plan for the actual use of the building from the start.
Because the same company handles design, permitting and installation, the plan that gets approved is the plan that gets built.
Technical detail
The engineering behind it
- Design basis
- Daily wastewater flow estimated from the home or the commercial use

- Step 1
Site evaluation
- Review the lot, buildings, slope and drainage
- Evaluate soil and groundwater conditions
- Locate wells, water lines and surface water
- Step 2
Design basis
- Estimate daily wastewater flow from use
- Choose the system type for the site
- Size tanks and the dispersal field
- Step 3
Plans
- Site plan with separation distances
- System layout and details
- Specifications for components
- Step 4
Permit
- Prepare and submit the application
- Respond to county review comments
- Receive approval to construct
- Step 5
Installation
- Set tanks, risers and piping to plan
- Install the field and the controls
- Test before backfill
- Step 6
Inspection
- Coordinate the required inspection
- Review the system with the owner
- Explain maintenance requirements
Illustrative layout. Required separation distances are set by state rules and your county, and we confirm them for your property during the site evaluation.
- 1
Wells and water lines
Septic components must stay a required distance from water wells and water supply lines to protect drinking water.
- 2
Property lines and easements
Tanks and fields need minimum clearances from property boundaries, so the layout has to fit inside the buildable area.
- 3
Surface water and drainage
Streams, ponds and drainage paths need a protective buffer, and the field must not sit where water pools.
- 4
Buildings, drives and slope
The layout also works around the house, driveway, trees, slope and where the soil is suitable.
FAQs
Septic system design: common questions
How much does septic system design cost?
Cost depends on the property, the type of system and whether it is residential or commercial. Contact us with your address and a short description and we will give you a free quote.
Why do I need a designed septic system?
In Texas, new on-site sewage facilities generally need an approved design and permit before installation. A design based on your actual site conditions also protects the system and your property for years.
Which type of system will my property need?
It depends on your soil, lot size and local requirements. Conventional systems suit properties with good soil. Aerobic systems with drip or spray distribution are used where soil or space is limited and are common in new construction.
