Most of the customer care information that you will find online with regard to septic systems is geared toward residential consumers.

Commercial septic system users have a completely unique set of guidelines, care tips and maintenance schedules that they need to adhere to in order to keep their systems in healthy running order. There are many commercial businesses that use septic systems including restaurants, schools, hospitals, beauty shops and laundry facilities.

Wastewater and Water Usage

One of the biggest concerns for both residential and commercial clients is water usage and the amount of wastewater it adds to the system. Commercial systems that discharge less than 10,000 gallons of sanitary wastewater each day fall under the Massachusetts Title 5 regulation and all of the associated requirements. This includes Title 5 Inspections and rules regarding cleaning, usage and pumping, as well as repairs or upgrades of failed systems.

However, commercial systems that discharge industrial wastewater or anything other than sanitary wastewater must first store the non-sanitary wastewater in an industrial wastewater holding tank. These businesses must apply for a permit to use the industrial wastewater holding tank. Any sanitary wastewater from these same commercial businesses can continue to be discharged into an on-site system. The point is just to separate the non-sanitary wastewater from the on-site system for proper processing.

Industry-Specific Issues

Certain types of commercial businesses must address specific issues that are related to their unique industry. For example, according to Massachusetts State Law, printers, photo processors and dry cleaners must be certified under the Environmental Results Program (ERP), which is a program for streamlined permitting and compliance, due to the types of chemicals and industrial waste produced by their facilities. Other types of businesses will have other types of requirements under the law.

Beauty Shops

Under Massachusetts law, these facilities are able to utilize a septic system for toilet waste and regular shampoo water as long as they are using less than the 10,000 gallons per day limit. Wastewater that comes from chemical treatments, such as hair color, perms, straighteners, etc., must be store in an industrial wastewater holding tank with a permit from MassDEP. To faciliate this, beauty shop owners can choose to direct all sinks to the holding tank or use a special sink that has been separately plumbed for use with chemical treatments to ensure that the wastewater goes to the holding tank.

Hospitals

As long as it remains under the 10,000 gallon per day threshold, hospitals can send all sanitary wastewater from sinks, showers, toilets and laundry to a septic system. In most cases, however, hospitals will use much more than 10,000 gallons per day. Lab waste is considered to be industrial wastewater and must be stored in a MassDEP permitted holding tank.

Laundry Facilities

Again, as long as sink and toilet waste are sanitary and under the 10,000 gallons per day maximum, this type of business can send their wastewater to an on-site septic system. However, any wastewater from the laundry itself must be stored in a permitted MassDEP industrial wastewater holding tank. Businesses that offer both laundry and drycleaning services must fall under the regulation of a Dry Cleaner and are required to be certified under the ERP.

Office Buildings

As long as no chemicals or otherwise considered industrial wastewater is being produced, most office buildings are eligible to use an on-site septic system for sanitary wastewater that results from toilet waste, sinks and showers as long as it is under the 10,000 gallons per day limit. In this case, no other permitting or certification would be required.

Restaurants

Sanitary wastewater under 10,000 gallons per day can be discharged into a septic system if it comes from sink or toilet waste. Due to the food preparation and cooking that goes on in this type of business, all restaurants are required by Massachusetts State Law to install grease traps that can handle the wastewater that comes from the food preparation stations in the kitchen. All restaurant grease traps should be inspected on a monthly basis and must be cleaned once the grease level hits 25% of capacity or every three months.

Grocery Stores

As long as they use less than 10,000 gallons of water per day, grocery stores can discharge the wastewater from sinks and toilets to a septic system. Food preparation areas must have grease traps installed and, as with restaurants, should be inspected monthly and cleaned every three months or when the grease level reaches 25% of capacity.
