Hillview Estates Subdivision is under a watering restriction due to well interference. This restriction effects most of the 112 homes located in this northeast section of the township.
According to Linda Richardson, director of the Department of Public Works for Independence Township, Hillview Estates normally runs on two wells. These wells need to be cleaned about once every three to five years. The preferred way to cleanse the wells is through chemical treatments in which acids are used to rid the water of containments.
Richardson explained that these chemicals are difficult to use since the two wells are in close proximity. One well cannot be cleaned with chemicals because the chemicals would get into the other operating well . Due to this problem, the wells were not thoroughly cleansed. Over time, this caused the wells to loose production.
To solve the problem, a new well was drilled last year as a test production and was not put into use until recently. This well is 180 feet away from the two existing wells.
According to Richardson, the new well’s distance allows it to be used while the others are cleaned. However, this well being online caused other problems.
The new well was the source of a boil water advisory which began on July 1 and was lifted July 5. Coliform bacteria was found in samples taken at that location, which was the reason for the advisory.
Richardson said the problem is not likely to occur again.
‘As soon as we get the other two wells up and running again, we will shut down the new well and take more samples,? Richardson said.
For the time being, the new well is working with a chlorination system.
The older wells should be running within two to three weeks, Richardson said. The DPW has called two crews to begin the cleansing process this week.
The new well, as well as the cleansing of the older ones, is part of the DPW Drinking Water Revolving Fund Water Capital Improvements. Other improvements being made include new plumbing, new valves, a new 4800 gallon pressure tank and a new roof.
‘These new improvements will have little effect on the residences. The water will just be turned off once, in the middle of night. So people will just have to make sure their sprinklers aren’t running, and their water softeners are replenishing,? Richardson said.
Richardson also said she making continuous attempts to notify each resident of what is happening with the wells.
‘We hand delivered notices to everyone in Hillview Estates,? she said.
The DPW will send out another notice in the near future to make sure everyone is kept up to date.
