Inflow & Infiltration Program

The Clay Township Regional Waste District is dedicated to providing the best sanitary services to its customers. The implementation of an Inflow/Infiltration (I/I) reduction program provides for inspection of and certification of compliance for all properties connected to the District's sewer system. The program is a step towards a more efficient sewer system by reducing the amount of clear water that enters our system.
Currently during rain events flows can increase 500%. It is possible for the inflow and infiltration of clean water to exceed the capacity of the pumping stations and cause a sewer overflow. Implementation of this program will ultimately mean less flow and reduce the possibility of sewer overflows. The District will be contacting customers to conduct inspections in neighborhoods where high levels of inflow and infiltration have been observed. The inspection will verify that:
  • Downspouts are not connected to the sanitary sewer
  • The sump pump is not connected to the sanitary sewer
  • Cleanout caps are in place and watertight
  • No yard drains are connected to the sanitary sewer
  • There are no sinkholes or other indications that the sewer lateral is leaking
If no deficiencies are found, the District will issue a certificate of compliance. If deficiencies are found, the property owner will be notified and must make corrections immediately. The property owner will need to schedule a follow up inspection. Although there is no fee for the initial inspection, there is a $100 re-inspection fee. The program also requires that at the time of the sale of a property that the property is in compliance with the District's I/I standards. If the property for sale does not already have a certificate of compliance on file with the District, the owner must notify the District and schedule an inspection. 
 
A sewer surcharge of $20 per month will be assessed and added to the sewer bill under the following circumstances:
  • If a certificate of compliance is not issued within 30 days of the change of ownership.
  • If an inspection is not scheduled within 30 days following a notice of scheduled neighborhood inspection.
  • For a non-compliance issue, a failed inspection or failure to make repairs.
Such sewer surcharge shall be in addition to any and all other fees levied under Sewer Use Ordinance 11-14-11.  The complete policy can be downloaded here. A copy can also be picked up at the District's office at 10701 North College Avenue, Suite A, Indianapolis, 46280 (location info). The policy was developed to help both property owners as well as experienced plumbers understand this program. This program is new to our service area but is based on similar programs being successfully operated in other sewer utilities.
 
The District welcomes your comments on this program. The policy will be reviewed and revised as needed to reach our goal of reducing I/I. If there are any questions concerning this policy, please do not hesitate to call the office at 844-9200.
