South Englewood Sanitation District No. 1 (SESD) has a number of programs to operate and maintain its sanitary sewer system and keep it in good working condition.

Scheduled Maintenance

Outside Englewood City Limits
SESD’s maintenance contractor, DES Pipeline Maintenance (DES), jet cleans and televises a portion of SESD’s sanitary sewer system every year. All pipes are jet cleaned and televised every 2-years. SESD’s Engineer, Kennedy Jenks, reviews the video taken by DES and assesses each pipe for any maintenance or structural issues.


Inside Englewood City Limits
The District contracts with the city of Englewood to maintain the sewer lines within the Englewood city limits. All SESD pipes are jetted every year.

Unscheduled Maintenance

Unscheduled maintenance can be performed as a result of seeing a maintenance issue in scheduled video, or as a result of a call from a customer or other entity. This work may include removing roots or blockages in the sanitary sewer system.

Note, SESD’s maintenance contractor or City of Englewood maintenance staff are only able to remove roots and blockages from SESD’s sanitary sewer main line. We recommend all homeowners maintain their sanitary sewer line to prevent root or debris accumulation.

Capital Improvement Projects (CIP)

Every year, SESD rehabilitates a portion of the sanitary sewer system that is observed to have structural issues, such as cracks or breaks. It is SESD’s preference to rehabilitate using trenchless, “no-dig,” technology, such as installing cured-in-place-pipe (CIPP), that only require manhole entry. In some extreme cases trenchless rehabilitation is not possible and excavation is necessary. In all cases, SESD’s selected contractor will need to set up temporary bypass piping to convey sanitary sewer flows during CIPP installation or excavation. The contractor will make all attempts to minimize disruption to the public and will notify residents or businesses that may be directly affected by this work.

Industrial Pretreatment Program

SESD's pretreatment program is implemented by the city of Englewood on behalf of the District.

The industrial pretreatment program helps to prevent excessive amounts of fats, oil, grease (FOG) or petroleum oil, grease, and sand (POGS) from entering the sanitary sewer system. When these materials enter the system they increase the risk of clogging and may result in a backup. SESD works with the South Platte Water Renewal Wastewater Treatment Plant in enforcing its Industrial Pretreatment Program. This program involves periodic inspections by the city of Englewood of businesses that generate either FOG (such as a restaurant) or POGS (such as a car wash), and educational outreach regarding Best Management Practices (BMPs).
