BCWA: Capital plan has measures for addressing THM

BCWA

The Bristol County Water Authority office on Child Street in Warren.

The Bristol County Water Authority has already started work toward reducing trihalomethane levels in local water through several initiatives spelled out in a recently adopted capital plan.

BCWA Executive Director Pamela Marchand said a number of the plan’s elements could be up and running by the end of next fiscal year provided a rate increase is approved for the coming budget cycle. Ms. Marchand said the plan is designed to optimize the distribution system, and these capital measures will also have an impact of THM levels.

One of these upgrades is the installation of a new instrumentation system – SCADA. The system allows for enhanced pacing and analysis of chlorine levels. THMs form based on interaction between chlorine and natural organics in water.

Additionally, the plan calls for the implementation of a new bacteria analysis system. It will help determine the exact levels of chlorine needed to keep water clean.

Ms. Marchand said the plan also includes a new mixing system for the water storage tank to fluctuate water in and out quickly and establishing unidirectional flushing which, while more labor intensive, will help move sediments out of water mains.

A long-term solution centers on a 20-year main cleaning and lining project. The BCWA recently wrapped up a pipe-lining project on Franklin Street, in Bristol, and is expected to perform similar work on 50 miles of pipe over the next two decades.

Ms. Marchand said the work is beneficial because it lines pipes with a layer of cement that prevents water from coming into direct contact with iron piping.

    Wish they would test the 2400 low pressure ratepayer area’s for contaminates, especially those who have water pumps. The RI health department has stated and are formulating rules for people who have pressure less than 20 coming in their house as they are at higher risk of contaminates into their drinking water.

    Not to mention the helper pumps in the house actually sucking the water from the street pipes create an even higher risk of that since they disturb the sediments in the pipes that lays there do to low pressure, pulling that in to the house as well. This is proven by in house filter systems that last only 1/3 the time they do in a normal pressure ratepayer also with pump failures and appliances such as dishwashers that fail in 1/2 the time of their life span or sooner.

    One wonder where the concern for this is? The average ratepayer obviously matter much less that franklin street apartment complex. Yet we face greater danger to our health then they did. We also pay anywhere from 2 to 3 times for our water than regular ratepayers due to the pumps and filter systems we must have that the BCWA will not fix going on over 25 years now that I have been a customer.

    Funny how they say it is about money, but not about money on flanklin and popaquash, RWU area etc. These low pressure area’s exist in all three towns and the BCWA and politicians could not give a damn. Not to mention 50% of fire hydrants under required pressure. Disgusting and criminal in my book.

    Hello I am replying to your email below regarding federal funds for BCWA. Federal funds are available for water projects such as the one you have mentioned below. In most circumstances the money is given directly to the state to distribute. I’m not sure whether BCWA has sought assistance from the state, but I will try to find out.

    Thanks
