Protection of collection system

Why

Implementation and Adherence to your

S ewer Use Ordinance (S UO)

Determining whether an industry needs

permitting, spill plan, inactivation step for Biological S afety Levels (BS L) etc.

Determining the appropriate

Pretreatment devices for each individual proj ect

Prevent concessions by adhering to the

S UO and its requirements

Prevent costly corrections or retro-fits

after construction has finished

Why

Why we require Pretreatment devices ? S ampling equipment and flow monitoring at industries to help identify wastes streams and loading rates of pollutants to Treatment Plants. Reduce the amount of Fats, Oils & Grease (FOG) Oil/ water separators at car wash and automotive facilities, hydraulically operated elevators.

Why do we monitor for FOG?

38

 Our goal is to have a

free-flowing collection system, unobstructed by debris.

 Fats, Oils, and Greases

clog sewer pipes, which prohibits the free flow

f wastewater in the

collection system.

 To reduce the risk, we

encourage source control with pretreatment limits.

Is FOG a Local Problem?

The good habits of Cook County citizens coupled with the ginormous size of our tunnels help keep our waste moving.

Closed Landfill Exemption

49

In 2015, the S ewage and Waste Control Ordinance was updated with the following language:

Effluent leachat e discharges from landfill facilit ies t hat are closed for t he accept ance of wast es shall be exempt from t his limit at ion for Fat s, oils and greases (FOG) (t ot al), provided t hat approved Best Management Pract ices (BMPs) are implement ed and maint ained. Failure t o adhere t o BMPs may result in enforcement act ion.

What is the Solution?

Good housekeeping

Cleaning connection between facility and

sewer

May result in a decrease of user charges
Extends the life of flow measurement

equipment Alternate uses

Resource Recovery
Conversion to feedstock

FOG Control: Going Beyond Just Enforcement

Going Beyond Just Enforcement

FOG Program History

Began in 1997
Over 750 stop ups in sewer mains
Causing S

anitary S ewer Overflows

No controls on maj ority of restaurants
Residential areas had maj or issues from FOG

Beginning the process

Contacted the business license office
Obtained a list of all restaurants in

Columbus

Began systematically inspecting all

facilities

Used EP

A and WEF guidelines for inspection

Began with larger restaurants having

them install or fix old in-ground traps

57 58

SLIDE 30

12/12/2019 30

The process continues

Next were the

secondary or smaller restaurants (Mom and Pop S tores)

Less of a

contributary load, but had multiple locations

Began educating

and trap installation

Stages of Enforcement

59 60

SLIDE 31

12/12/2019 31

Began permitting haulers and manifesting loads to treatment facility

CWW permits and inspects all

haulers that utilize CWW for disposal

Manifested each load to the

facility

Maj ority of all hauled waste goes

to head of the plant

Later CWW built a FOG receiving

station

But it was so much grease for the treament plant

2017 2018 Grease 1,581,409 Grease 1,607,440 FT Benn 360,485 FT Benn 257,700 Industrial 371,300 Industrial 353,100 Total 2,313,194 Total 2,218,240

12/12/2019 34

CWW began a new process

Thermophillic digestion

with plug flow reactors

Added grease

to digesters and boosted methane production

Methane then used

for co-gen of electricity

Cut plants power usage

by 2/ 3

FOG Partnerships

S

maller restaurants needed a way to dispose of the grease from their secondary traps

Apartment Complexes were dealing

with private property sewer clogs due to grease

CWW still had issues in smaller mains in

residential areas

What was the solution?

Grease Recycling Program

CWW currently has over 90 small

restaurants participating

Over 80 apartment complexes
11 residential FOG drop off

sites and currently planning 5 more

Columbus Water Works received NAQWA's National Environmental Award for its FOG Program
