Appomattox River Water Authority 
 
Brief History 
The Appomattox River Water Authority was created by the General Assembly in 1962 under the Water & Sewer Authorities Act to provide an adequate water supply to its members.  Membership is made up of the City of Petersburg, the City or Colonial Heights, Chesterfield County, Dinwiddie County and Prince George County.   
 
$8.5 million of revenue bonds were sold in October, 1964 to build a Treatment Plant, water lines, dam and reservoir.  Construction started in 1966 and was completed in 1968 for the 22 MGD facilities.  In October 1983 the Authority issued $12.5 million of Revenue Bonds to expand the Plant to 46 MGD and the work was completed in late 1985. $2.2 million of Revenue Bonds were issued i 
n 1991 to fund two sludge lagoons.  In 1997 the Authority built a $2.5 million chloramine addition to the plant with its own funds.  Only a portion of the 1983 Bonds remain outstanding. 
 
Facilities 
1.  Land - Approximately 6,000 acres were purchased.  3,100 acres was flooded for Lake 
Chesdin, 2,700 acres is a flooding area surrounding the lake and approximately 200 acres makes up the treatment plant complex and immediate area. 
 
2.  Dam & Reservoir - The Brasfield Dam impounds the Appomattox River to form Lake 
Chesdin.  The lake stores approximately 12 billion gallons of water.  The dam is 55 feet at the highest point, 1250 feet long and has an 800 foot long spillway. 
 
3.  Filter plant - The filter plant complex houses the Authority's Administrative, Laboratory, 
Operational and Maintenance departments.  The plant itself is capable of 46 MGD of treatment capacity, has 6.5 million gallons of storage capacity and can pump up to 46 MGD to its members. 
 
4.  Pipe lines - The Authority owns an 
d maintains approximately thirteen miles of 42", 30", 24" and 16" transmission lines. 
 
5.  Meters - The Authority has 12 water meters to register consumption by the localities.  
Invoices for water used are sent out at the end of each quarter. 
 
6.  People - The Authority is controlled by a Board of Directors made up of one person from each member jurisdiction appointed by the local governing body.  There are 19 full time employees to cover 24 hour per day, every day operation (two administrative, three laboratory, four maintenance and ten operational).  An organizational chart is attached.

V. FIVE YEAR ACCIDENT HISTORY 
 
1980 to 1998 - None 
 
June 22, 1998 - Two employees, one from maintenance and an asstistant operator, were changing chlorine cylinders. They purged the pig tails and cut off the manifold valves. The two changing the cylinders were called away for a problem.  The Assistant then cut the two stand-by cylinders into service by opening the manifold and cylinder valves and they left.  A short time later the assistant and the operator returned to complete the cylinder change out. The assistant cracked the pig tail nut at the cylinder and heard a leak.  He quickly tightened the nut.  The operator tried it with the same result.  The operator decided to purge the line again.  He opened the mainfold vavle for the cylinder and assumed the other cylinders were not open.  Since they were open, he had charged the pig tail with chlorine in stead of purging the line.  When he cracked the pig tail nut 
again the pig tail "blew off" and a chlorine leak occured.  The leak amounted to 740 pounds of chlorine and an evacuation of the plant. 
 
July 23, 1998 to June 1, 1999 - None 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
ARWA - Emergency Response Program 
 
The Authority's personnel are trained to respond to small leaks of chlorine, ammonia or propane. Severe leaks will be handled by the Chesterfield Emergency Response Team by calling 911. 
 
Employees are trained annually on eleven safety programs and records are kept of the tarining.  Approximately one safety area is reviewed monthly.   The annual chlorine safety, respirator training, emergency action plans, personal protective equipment and risk management plans all effect the Authority's ability to handle emergencies.   
 
ARWA - Planned Changes to Safety 
 
The Authority's safety plans are reviewed annually and appropriate revisions are made then.  The eleven safety programs are rewiewed annually with Authority personnel in safety training sessions.   
 
The Au 
thority has met with Chesterfield County Emergency Response Team to cooridinate their response to an emergency at the Authority.  Such a response could be caused by one of the hazardous chemicals on site or other reasons.  The county conducts routeen inspections of the facilities to continue familarization with the facilities.  The Authority provides the state and county with annual copies to tne Sara title III reports of all chemicals on site.
