Your sewer bill is due on the 20th of the month. After the 20th, a late fee will be added of 10% of the current balance only. The bill is for the prior month as we bill in arrears and is based on a 30-day billing cycle.

Residential billing rates for customers with private wells pay a flat rate of $33.51. Residential customers with water service pay a base charge of $13.45 per residential unit and a use charge of $2.86 per 1,000 gallons based on their annual balanced consumption usage. Commercial customers with private wells as their water source pay a flat rate based on the property use. Commercial customers with water service provided by Citizens Water or Carmel Utilities pay a base charge applicable to the size of the meter(s) at the service location and a use charge of $2.86 per 1,000 gallons of water consumed. Please refer to Sewer User Rate Ordinance 05-10-2021-R for a complete listing of charges.

Residential balanced billing is a consistent monthly sewer bill based on the residential customer's average water usage in the winter months. The winter water usage is used to calculate the monthly average since these are typically the low usage months with no irrigation. A customer's average usage is established in August and used for the sewer billing for the next 12 months. Residential balanced billing provides a consistent monthly bill amount.

* Residential balanced billing will provide a consistent bill amount over 12 months.
* Each customer receives a balanced bill based on their winter metered water usage.
* Balanced billing eliminates the monthly fluctuation that often occurs from using estimated water meter readings.
* Summer lawn watering and other outdoor usage is excluded without the necessity of an irrigation meter since the balanced bill consumption is based only on winter meter readings.

The balanced billing rate for each account is set in August and is used for the next 12-months. Any change in consumption amount affects only future bills. There are no extra charges or credits at the end of the 12-month period.

The Utility does not read meters since these are provided by the water utilities. TriCo receives your meter reading from the water utilities. If you have questions regarding your meter readings, you should contact your water provider, either Citizens Water at 631-1431 or Carmel Utilities at 571-2442.

The water company bills in 100 cubic units or 750 gallon units. TriCo bills in 1,000 gallon units rounded to the nearest tenth. From the example above you would need to do the following:
8 X 750 gallons (CF Unit) = 6,000
6,000 ÷ 1000 gallons (TriCo unit) = 6.0

TriCo does provide E-billed statements. See below for links and additional details.

TriCo may make an adjustment if the water utility adjustment affects the sewer bill. For a residential customer with balanced billing, if the adjustment affects some or all of the months that are used to calculate the average winter consumption, then the average and the affected bills may be adjusted. For a commercial customer, the bill may be adjusted in accordance with the water utility adjustment. Please advise our Customer Service department if you have received an adjustment from your water company.

Check your exterior cleanout. Cleanouts are normally installed on your service lateral within three (3) feet of your foundation. It should have a white threaded cap on it and is probably close to level with the surrounding grade. Cleanouts often have landscaping around them, so check your foundation planting beds. With water running in your home or business, take off the cap and use a flashlight to see if any wastewater is flowing past the cleanout. If it is not flowing, it's likely a problem with your house plumbing that a plumbing contractor will need to fix. If there is no obvious flow or the cleanout is full of standing water, it may mean a problem with your service lateral between your cleanout and the tie-in point with our main. Or it could be caused by a blockage or failure in the main sewer line. In either case, our staff will want to investigate to determine a possible cause. Contact our office at 317-844-9200. and describe the problem. Our staff will respond by phone or onsite. Once the problem has been identified, responsibility for any repairs can be determined. TriCo is responsible only for the main line. If the problem is in this area, TriCo will make sure it's resolved in a timely manner. If the problem is found to be in the service lateral or in the internal plumbing, it would be the homeowner's responsibility.

This is usually caused by the presence of a dry trap in a sink or floor drain that has not been used in a while. Pour water into the drain to fill the trap. This acts as a block between the normal organic odors in your sanitary plumbing and the living areas of your property. Another potential cause is a blocked roof vent. Each bathroom should be vented beyond the roof line to allow the plumbing system to operate properly and dissipate normal sewer gases to the atmosphere. Birds may find your vents an attractive nesting site and that can be a prime cause of vent blockage. Keep those vents clear and you will eliminate one potential source of sewer odors.

An overflowing sewer or manhole constitutes an emergency for TriCo so please call our office immediately at (317) 844-9200 so that we can promptly investigate. Try as we might to prevent them, situations do arise that cause sewer blockages that result in overflows. Cooking grease, garbage disposal debris or other foreign objects can accumulate in sewer lines and create restrictions. Please be sure to keep children and pets away from a suspected sanitary sewer overflow as contact with untreated wastewater can be hazardous to your health. If there is contact with untreated wastewater, wash immediately and thoroughly with anti-bacterial soap.

Common symptoms of illness associated with contact with wastewater may include diarrhea or nausea. If you have been in contact with wastewater and feel that you need help, please contact appropriate medical and health care professionals.

You can expect to see someone in a TriCo vehicle and wearing clothing with our logo. If you have doubts that someone is a TriCo employee, please ask them for their picture identification as well. Report any problems to the Utility Director at the main office.
