During the past year, the Division has treated 767.3<br />

million gallons <strong>of</strong> wastewater at a treatment efficiency<br />

<strong>of</strong> 90%. The <strong>Town</strong> is required to maintain a<br />

treatment efficiency <strong>of</strong> 85% under the current discharge<br />

permit issued by the Connecticut<br />

Department <strong>of</strong> Environmental Protection. In treating<br />

the wastewater, 1,381,631 pounds <strong>of</strong> wastewater<br />

solids were removed and transported to the<br />

Hartford Metropolitan District Facility (MDC) for final<br />

processing in accordance with the <strong>Town</strong>’s participation<br />

in a cooperative regional sludge management<br />

program. Wastewater service is provided to more<br />

than 7384 residential homes and to more than 328<br />

industrial and commercial businesses in <strong>South</strong><br />

<strong>Windsor</strong>, East <strong>Windsor</strong>, Vernon, and Manchester.<br />

Service is provided to out <strong>of</strong> town properties in<br />

accordance with the provisions <strong>of</strong> intertown sewer<br />

agreements; through such agreements communities<br />

are benefited by limiting the number <strong>of</strong> expensive<br />

pump stations which would have had to be<br />

constructed and operated.<br />

The Division completed the installation <strong>of</strong> a new<br />

Treatment Plant wastewater disinfection system. An<br />

ultraviolet (UV) disinfection system was put into<br />

operation and replaced the pre-existing chlorine gas<br />

disinfection system. The new system has provided<br />

a more cost effective means <strong>of</strong> disinfection while<br />

meeting State Department <strong>of</strong> Environmental<br />

Protection requirements. The new system will also<br />

improve worker and public safety. Project costs<br />

were about $1.1 million and were funded through a<br />

state grant (20%) and a 20 year low interest loan<br />

(2% annually).<br />

Other Division initiatives during the past year included<br />

the completion <strong>of</strong> construction <strong>of</strong> odor control<br />

systems at the Treatment Plant. The odor control<br />

technology selected is an innovative technology –<br />

"oxygen agglomeration", and <strong>South</strong> <strong>Windsor</strong> was<br />

one <strong>of</strong> the first in the country to place into operation<br />

such a technology. It is based on the light absorptive<br />

theory developed by Albert Einstein and Paul<br />

Habicht. It was found that it is possible to reproduce<br />

electricity found in the air in a room by using<br />

an ion generator. When this ion generator is placed<br />

in HVAC ductwork and air is passed over the generator,<br />

millions <strong>of</strong> ions quickly fill the ventilated room<br />

space. These ions form oxygen rich clusters that<br />

interact with the foul air and neutralize the odors.<br />

During this past year, the Division has initiated a<br />

Facilities Plan, which will evaluate the entire sanitary<br />

system throughout <strong>Town</strong> to identify areas requiring<br />

improvement in order to meet future <strong>Town</strong> growth<br />

needs and state and federal regulatory requirements.<br />

This project is expected to be funded (55%)<br />

by a State <strong>of</strong> Connecticut Department <strong>of</strong><br />

Environmental Protection Grant.<br />

During Public Works Week in May <strong>of</strong> this year,<br />

Public Works Divisions demonstrated the equipment<br />

and services provided to the community in a program<br />

held for the children at Pleasant Valley School.<br />

Refuse / Recycling Collection and Disposal – The<br />

<strong>Town</strong> is a member <strong>of</strong> the Mid – Connecticut Project<br />

which is a regional cooperative organization <strong>of</strong><br />

Hartford area communities for the purposes <strong>of</strong><br />

refuse disposal and recycling. Refuse from member<br />

communities is processed at a Hartford energy<br />

recovery facility operated by the Connecticut<br />

Resources Recovery Authority (CRRA) where it is<br />

converted to electricity for use in the Hartford area.<br />

The <strong>Town</strong> adopted a recycling ordinance in<br />

September 1990 and implemented a residential<br />

curbside recycling program the following month.<br />

The program has subsequently been expanded to<br />

include cycling <strong>of</strong> the following items: newspaper,<br />

corrugated cardboard, glass and metal food containers,<br />

plastics, storage and rechargeable batteries,<br />

scrap metal, magazines, junk mail, clothes, aseptic<br />

packaging, leaves, and Christmas trees. The <strong>Town</strong><br />

also collects and recycles antifreeze, and used oil filters<br />

at the Public Works Garage on Burgess Road.<br />

During the year, 378 residential homes disposed <strong>of</strong><br />

a variety <strong>of</strong> household products (2.8 tons) containing<br />

substances hazardous to family health and to<br />

the environment. Through the recycling programs,<br />

the <strong>Town</strong> has been able to reduce the quantity <strong>of</strong><br />

solid waste that would otherwise be disposed <strong>of</strong> at<br />

a landfill: this cost avoidance represented cost<br />

savings to the <strong>Town</strong> during the past year <strong>of</strong><br />

$389,989.<br />
