Porter Township Area Utility Authority Sewer Connection Procedure

Residents will be notified 90 days before it is time to hook up to the sewer. At that time permits will be available at the Township Administration building. The cost for the permit is $50.00 and this includes the cost of a final inspection. The permit forms must be filled out including the installation drawing for the final inspection.The permit applications are to be signed by the contractor or the homeowner. After the permit is issued, the connection to the sewer can be installed. The entire length of the connection cannot be backfilled until after the inspection.

Pipe Materials and Construction Methods

Pipe materials shall be Schedule 40 PVC or equivalent with glued or premium joints. Primer shall be purple dye tinted so that it is visible during inspection. All materials and installation shall be in accordance with applicable plumbing codes. Pipe must be laid from the house to the line with a fall of 1/8-inch per foot for 4-inch pipe. Minimum depth of bury is 18- inches.

Connection to the Sewer Tap

The connection to the 6-inch public sewer tap shall be made with flexible rubber connectors with stainless steel bands. Fernco or equal (watertight) if 6-inch pipe is used it shall be a 6" by 6" connector and if 4-inch pipes are used it shall be a 6" by 4" connector.

Cleanouts

One cleanout shall be installed at the connection of the private sewer to the public sewer. This cleanout shall be terminated 2-inches below the grade with a watertight plug. Additional cleanouts shall be installed, one at the house connection and then one for every 100-feet of service length and at every change of direction. All cleanouts shall be permanently marked by a 1/2 x 18-inch rebar taped to the cleanout and set 2-inches below the grade.

Sewage Ejector Pumps

An electrical permit is required for a sewage ejector. The cost of the permit is $50.00. It is contingent on wether there will be a 110V or 220V circuit and wether or not there is an alarm installed. If an additional inspection fee is required it will be $45.00 for each inspector visit. The ejector pumps must be sized for the needed flow and head conditions. The maximum dose per cycle of the pump shall be 100 gallons, minimum of 50 gallons. The sewage ejector shall be installed in a tank designed for intended use. The tank must provide a maximum of 100-gallons per dose. The forcemain from the sewage ejector shall be a minimum of 2-inch diameter unless an approved grinder pump is used. The forcemain shall be terminated into the side of the cleanout at the public sewer no less than 6-inches above the invert with a watertight fitting. Access at the grade to the ejector or grinder pump is recommended.

Septic Tanks

All septic tanks must be pumped by a licensed waste hauler and filled. The plumbing inspector must see that they are disabled and filled, so do not cover until they have been inspected.

This is a sanitary sewer only. No eaves or sump pumps shall be hooked to the system.

Billing for Service

Once there has been a final inspection, the billing for the use of the sewer will begin the following month or at the end of 90 days whatever comes first. The monthly usage fee is $40.00
