Septic Systems

How does a septic system work?

How do I know when my septic tank is full and it needs to be pumped out?

A properly functioning tank is always full. A typical septic tank has a capacity of 1000 gallons and, if working properly, will always be full. The idea behind the septic tank is that as one gallon enters the tank from the house, one gallon leaves the tank and goes to a drain field. The 1000 gallon tank allows fats, oils and grease to float and solids to settle. A good time to pump your tank is when either of those levels exceeds 6-8 inches. The average household will accumulate these levels in 2-3 years.

How do I know if my septic system is not functioning properly?

Pools of wastewater around your septic tank, sewage smells around your system or house, and water flow backups when you flush the toilet or do laundry are all signs your septic system is in need of help.

How can I keep my system healthy?

We recommend pumping your system every 2-3 years. Avoid putting non-biodegradables, (i.e. diapers, feminine products, etc.) in your toilet. Be watchful of water usage. In the kitchen be sure to drain the grease from your frying pan into a jar before washing the pan. Fats, oils, and grease can cause a clog in the septic line.

How close can I plant a tree to my septic system?

Grass and small plants are fine, but we recommend not planting trees within 10 feet of your septic tank or drainage field.

Does the person pumping my septic tank have to be licensed?

Yes, per DNREC, your technician must hold a Class F Liquid Waste Hauler’s license.

How often should I get my septic tank pumped?

Every two-three years.

My septic system has an alarm and it is going off. Why?

You have what we call “an engineered system.” That means there is a pump in a separate tank that doses water to the drain field. The alarm means the water in that dosing tank is above the proper operating level. Most likely, the pump is not operating for some reason which may be electrical (so check your breaker and/or connections at the alarm).  If not, please call our office and we will send someone to assist you in locating the problem.


Septic Inspection

I’m buying a house with a septic system. Should I have it inspected?

We feel that it is very important to have your potential system inspected. If you live within the Inland Bays Watershed, septic inspections are required. Our inspection will give you a snap-shot of the current system’s operation and can save you from unexpected problems in the future.

What happens if my septic inspection comes back and parts of the system are failing?

At Clean Delaware our technicians on staff are licensed to repair all of your septic problems. Our service trucks carry the necessary parts to fix most small septic problems. Should you require a new system, we can assist you in each step of the process.


Septic Repair & Installation

We had our septic pumped and your technician mentioned risers and a filter. What are they?

Risers are lids at or above ground level that allow easier access to your septic tank without the damage of digging in your yard. An effluent filter traps solids leaving the tank and prevents them from entering your drain field. Keeping solids out of your drain field will extend its life.

My septic system is failing. What do I do now?

The first step to replacing a septic system is to get a site evaluation of the property. The site evaluation will tell you the location, the size, and the type of system that can be placed or replaced on your property. An approved site evaluation is used to design a new system that turns into a septic permit. Once the system is permitted, Clean Delaware is licensed to install your new or replacement system. We would be happy to walk you through this process.  Contact Atlantic Resource Management for information regarding a site evaluation.


Commercial Pumping

Do you offer grease trap maintenance contracts for my restaurant?

Absolutely! Restaurants are required to enter into a grease trap contract with a licensed waste hauler stating frequency of pumping and method of disposal. We can assist you with the contract process, including providing a maintenance log for your files. We also offer line jetting service as well as 24 hour emergency service.
