RUNYAN SEWER IMPROVEMENT DISTRICT
ABOUT
Runyan Acres Sewer Improvement District 211 (RSID) has served the sewer service needs of the Runyan Acres community in Pulaski County since its formation in 1968.
Established to construct, operate, and maintain a sanitary sewer system for residents in the area, RSID continues to provide essential sewer service to homes and businesses west of Gravel Ridge and near Sherwood, Arkansas.
Today, RSID serves more than 1,500 customers and remains focused on reliable service, responsible stewardship, and continued investment in the infrastructure that supports the community’s health and quality of life.
RSID is currently proceeding with the construction of a new wastewater treatment plant, pursuant to consent order by the Arkansas Department of Environmental Quality (DEQ). This has resulted in an increase in sewer rates for RSID's customers. See the Construction page for more information.
Sewer Service FAQs
Backflow Prevention
### 1. ""What is backflow?""
**Answer**: Backflow can occur into a residence when there is a sewer line obstruction near the site of the residence. A sewer line obstruction can cause wastewater to flow backwards into a residential plumbing fixture connected to the sewer line. Backflow can cause significant damage to a residence.
### 2. ""How can a sewer line become obstructed?""
**Answer**: Sewer lines can become obstructed over time when items placed in sewer lines by customers accumulate, such as paper products that cannot dissolve, plastic products, and cloth.
A sewer line can also become obstructed when natural matter such as roots, soil, and rock breach a sewer line.
### 3. ""How do I prevent backflow in the event a sewer line backs up?""
**Answer**: It is the policy of RSID that each residence or business should have installed on its individual line, a backflow preventer.
A backflow preventer is a plumbing fixture which prevents backflow by a valve which closes when water flows in a backward direction to normal flow. These can be purchased through a hardware or plumbing retailer and installed by a licensed residential plumber.
### 4. ""Am I required to have a backflow preventer on my sewer line?""
**Answer**: When a customer is engaged in new construction or significant renovation, the customer is required to install a backflow preventer.
Any customer whose residence was constructed prior to 2015 is not required to have a backflow preventer currently installed on their sewer line.
However, RSID does not assume liability for damages that occur as a result of backflow when it takes reasonable steps to address the issue. It is the responsibility of the customer to ensure that their residence is protected from a backflow event.
