A sanitary sewer overflow (SSO) is an unintentional discharge, spill or release of untreated sewage into the environment or a property. SSOs are also known as sewer backups and the resulting flooding can cause damage to a property and pollute the environment. Raw sewage is dangerous because it contains bacteria and other hazardous microorganisms. Touching or walking through contaminated areas can bring germs into uncontaminated areas of your home. 儿童和宠物尤其容易受到伤害.
SSOs或下水道堵塞的原因
- A blocked or collapsed private sewer lateral
- Improper disposal of grease that creates blockages in sewer lines or internal plumbing
- Obstructions or breaks in the sewer lines or in internal plumbing
- 其他物品处置不当, 比如婴儿湿巾或抹布, 堵塞下水道或内部管道
- Unusually heavy rainfall, which can result in an inflow of stormwater into sewer lines
SSOs的影响 & SSO地图
SSOs can cause significant environmental and public health problems. SSOs that occur in streets can cause sewage to enter the storm drain system and travel to local waterways. 这会污染地表水, 危害水生生物, and interfere with the recreational uses of waterways and beaches. SSOs that occur within buildings can damage the property and its contents, which can result in financial costs for the property owner, and pose a significant health risk to residents of the property, 尤其是儿童和宠物.
State and federal regulations now require BWSC and other sewer agencies to report SSOs in order to meet Clean Water Act requirements and to reduce the occurrence of SSOs across the BWSC system.
BWSC closely monitors sanitary sewer overflows that occur in Boston and maintains a Sanitary Sewer Overflows Map on the Maps page. The map and list identify recent SSO locations.
预防
Keep Drains and Sewers Clear of Fats, Oils and Grease (FOG)
Fats, oils, and grease (FOG) can cause blockages in sewer pipes and lead to SSOs. Grease should never be poured down sink drains or into toilets or garbage disposals. Instead, pour grease and oil into a covered disposable container and put it in the trash. “把它冷却——把它扔进垃圾桶。.食物残渣, 肉的脂肪, 乳制品, and butter and margarine should never be put down the drain or into a garbage disposal.
不要让湿巾沾到管道里
There are many disposable wipes that claim to be “flushable” and “sewer safe.” However, these wipes do not break down as they travel through pipes and into the sewer system. Wipes can create clogs in both household plumbing and the public sewer system and result in SSOs.
Wipes that should be disposed of in the trash, and not flushed down the toilet, include:
- 浴室擦
- 婴儿湿巾
- 消毒湿巾
- 巾
正确安装回水阀
Heavy rainstorms can cause overland flooding and sewage backups into properties in low-lying areas. While overland flooding cannot always be prevented, sewage backups can be avoided if your property is properly equipped with a backwater valve.
A backwater valve is a fixture that is installed on a sewer line or drain in the basement. A properly installed backwater valve prevents the reverse flow of water, 防止污水进入您的物业.
For more information see our Backwater Valve Regulations brochure.
维护和修理下水道支线
下水道侧面, 也被称为建筑物的下水道, is the waste disposal pipe connecting a property to the BWSC sewer main in the street. BWSC is responsible for maintaining its sewer main located in the public way. Property owners are responsible for maintenance and repair of their building’s entire lateral from inside the property’s basement to BWSC’s sewer main in the street. Blocked and collapsed sewer laterals can lead to sewer backups into a property. Have your sewer lateral inspected for blockages, breaks, and leaks. 如果检测到问题, 修复, 替换, or relining your sewer lateral can help prevent sewer backups.
The BWSC 下水道横向财政援助计划 is a financial reimbursement program that is designed to assist property owners with the cost of repair or replacement of their sewer laterals.
For more information see our 下水道横向财政援助计划.

正确安装水泵
Install sump pumps to help keep your home dry by pumping ground water away from your foundation. Sump pumps must drain to your lawn or other yard area. It is illegal to have the sump pump connected to the sewer system. Such connections allow a tremendous amount of water to enter the system which, causes the sanitary sewer to exceed the pipe's capacity during wet weather and sewage can overflow into nearby ditches and streams or back up into downstream homes.
