Septic tank pumping and service around Cabot

Cabot's sewer has been built out one main at a time, each paid for by an improvement district, a developer or the owner whose land it reaches. That leaves a patchwork: a street of houses on city sewer, then a road of older homes and acreage tracts toward Ward, Austin or the county line where each house still has a tank and a field in the back yard. If you are in the second group, this page is the Lonoke County part of the story: how to tell which group you are in, what the ground around Cabot does to a drain field, where the permit records sit, and what to expect when a pump truck comes out. The general material on intervals and pricing is on septic tank pumping.

Sewer, septic, or a grinder pump?

Cabot WaterWorks runs the city's wastewater collection, treatment and disposal system as well as its water (Cabot WaterWorks operating policy, section 2.14). Its bill lists water and sewer as separate charges, so the quickest test is the bill itself: a sewer line item means your drains go to the city, and a bill with water and no sewer means the wastewater stays on your lot (Cabot WaterWorks 2026 rate sheet). Plenty of houses near Cabot buy water from a different system altogether; the utility's own list of neighbors includes Austin Water, Ward Water, Mid-Arkansas Water and Grand Prairie Bayou Two Water (Cabot WaterWorks FAQ). Who sells you water says nothing about where the toilet drains.

There is a third case that confuses new owners. Cabot WaterWorks serves some subdivisions through a pressure sewer, which needs a grinder pump at each house; the homeowner buys the pump from an approved vendor and pays a $300 connection fee per pump (operating policy, section 2.13). The utility's spec is a pump in a 30-by-74-inch buried plastic basin with an alarm panel (section 3.12). So a buried tank with an alarm in a Cabot subdivision is not automatically a septic system. If the bill carries a sewer charge, that basin is part of the city sewer. If it does not, and the alarm box sits next to an air pump, you probably have an aerobic septic system, which has its own monitoring rules.

When the sewer main reaches your road

Cabot WaterWorks does not run sewer to unserved property at its own cost. Its policy names three ways a main gets extended: an improvement district that assesses the properties it serves, a developer who builds the lines into a new subdivision, or an owner who pays by the foot. A main paid for that way has to run to the far edge of the property so the next owner down the road can extend it, and a house's service line may not cross a neighbor's lot to reach it (section 2.12). Every new connection is inspected by the utility before the trench is backfilled.

The state rule runs alongside the city's. Under ADH rule 4.1 a building has to connect when a sewer lies within 300 feet of where its sewer line leaves the house and the connection doesn't cross someone else's property (ADH onsite wastewater rules). Those two "no crossing" conditions line up, which is why one house on a road ties in and its neighbor keeps pumping a tank. Before paying to rebuild a failed drain field near town, it is worth finding out where the nearest main is.

What the ground around Cabot does to a drain field

Lonoke County shares a USDA soil survey with Prairie County (NRCS survey area AR680, the data behind the free Web Soil Survey). We queried how its major soils rate for septic tank absorption fields. Of roughly 784,000 rated acres, about 755,000, some 96 percent, come out very limited, and only about 29,000 somewhat limited. Two reasons dominate: slow water movement through the subsoil, on about 781,000 acres, and a saturated zone close to the surface, on about 755,000. Flooding adds about 154,000 more. The survey's biggest soils, Immanuel, Perry, Calhoun, DeWitt and Calloway, are the flat prairie and bottomland soils of the rice country south and east toward Lonoke and England.

Cabot itself sits on different ground. The map units NRCS draws in and around the city are mostly Leadvale, Sacul, Sawyer and Taft silt and sandy loams on the gentler slopes, the Linker, Enders and Mountainburg complex on steeper ground, and Amy and Oaklimeter soils in the flood-prone creek bottoms. Almost all of them rate very limited too, for two different reasons:

• Wet in winter and spring. Leadvale, Sacul, Sawyer and Taft are flagged for a saturated zone near the surface plus slow water movement. A field in that ground can work through the summer and back up in a wet February.
• Rock and slope. Linker and Mountainburg are flagged for shallow bedrock and slope, and Enders for very slow water movement. Little soil depth means little room under the lines.
• The exception. Smithdale sandy loam, on 5 to 8 percent slopes, is the one soil in the area rated only somewhat limited.

A rating is not a verdict on your lot; Arkansas has a Designated Representative dig soil pits for that. It does explain why so many Cabot-area systems are larger, pressure-dosed or aerobic, and why a tank that is allowed to overfill hurts a field here quickly. More on how soil decides the design is in central Arkansas soil and septic.

Wells and setbacks

Cabot's tap water comes from six wells pumping from the alluvial aquifer to a treatment plant in town, plus water bought from Central Arkansas Water (Cabot WaterWorks 2025 water quality report). The utility keeps a protection zone around each well, set up under a 2002 city ordinance, and septic tanks, privies and subsurface disposal fields are not allowed inside it (operating policy, section 1.15). On a private lot the state rule is the one to know: ADH keeps a septic system at least 100 feet from a private well, stream or lake and 50 feet from your own pond (rule 6.2). A rural Lonoke County place with a well, a stock pond and a field on the same couple of acres has to fit all three.

Permits and records: two health units

Lonoke County has two local health units, one in Cabot, (501) 843-7561, and one in Lonoke, (501) 676-2268, both in the ADH local health unit directory. Ask for the Onsite Environmental Specialist and bring the year the house was built and the subdivision and lot, which ADH says helps them find an old permit (ADH onsite wastewater FAQs). The drawing in that file shows where the tank and field were laid out, which is half of finding a buried septic tank. A repair that goes beyond swapping a part needs a permit first; the steps are in septic permits by county.

Booking a pump-out in Cabot, Ward or Austin

• Licensed truck, licensed receipt. Arkansas septic tank cleaners must be licensed, the truck has to show the company name, license number and tank capacity, and the license number goes on your receipt (ADH septic tank cleaner rules).
• How often. EPA's guidance is about every three to five years for a typical household, sooner with a small tank or a big family (EPA septic care guide).
• Slow drains in a wet spring. On the wet-season soils above, a slow field in March is common. If the tank was pumped and the drains are still slow, the field is the suspect; septic repair covers what comes next.
• Buying in Cabot? Find out first whether the house is on sewer, a grinder pump or a tank, then get the tank opened; see septic tank inspection.

One call

Call the number on this page, tell us the town and what the system is doing, and the request goes to an independent licensed septic contractor who works Lonoke County. We don't pump tanks ourselves; the contractor quotes the job before starting.

Questions people ask

How do I know if my Cabot house is on sewer or septic?

Check the Cabot WaterWorks bill. It lists sewer as its own charge, so a sewer line item means you are on the city system and water with no sewer charge means the house has its own tank. A water bill from Austin, Ward or another water system does not tell you either way.

Is a grinder pump the same as a septic tank?

No. Cabot WaterWorks serves some subdivisions with a pressure sewer that needs a grinder pump at each house, in a buried basin with an alarm panel. It sends wastewater to the city sewer; a septic tank keeps it on your lot.

Where do I get septic records for a house near Cabot?

From the Lonoke County health units in Cabot, (501) 843-7561, or Lonoke, (501) 676-2268. Ask for the Onsite Environmental Specialist and have the year built and the subdivision and lot number ready.
