MEMORANDUM <br />TO: Chair, Planning Commission <br />FROM: Greg Schroeder, Public Worlcs Director <br />DATE: September 1, 2004 <br />RE: Booster Station Antenna Tower <br />The City of Little Canada 1.5 million gallon water tower is located next to the City Center. The <br />City of Little Canada is obligated ensure the water level in our water tower is maintained at <br />levels that will provide sufficient water for consumption and fre fighting at appropriate <br />pressures. To accomplish this, there are wntrols installed at the water tower that talk to the <br />conh~ols in our booster station that turn pumps on and off when needed. The water tower and <br />booster station currently talk to each other via a special data telephone line that costs <br />approximately $87 per month. Over the last few years we have been experiencing trouble with <br />this telephone line resulting in water levels lower than allowed and unwarranted call outs of staff. <br />Last month, the telephone line failed again, in addition a critical module in our control at the <br />Booster Station also failed and cannot be replaced. We have jury-rigged our system to operate <br />until we determined the best course of action. <br />To resolve this problem we investigated four options: <br />1) Keeping the existing telephone line and installing the controls that are similar <br /> to those located in the water tower in the booster station. <br />2) Obtaining a different telephone line and installing the controls that are similar <br /> to those located in the water tower in the booster station. <br />3) Install sensor controls on the water lines in the booster station that can sense <br /> water levels in the water tower. <br />4) Installing a radio system that will enable these controls in the water tower talk <br /> to the controls in the booster station. <br />When we contacted the Qwest and they indicated that they could not provide a line more reliable <br />than they are now. The existing telephone line is not reliable and is costing the City of Little <br />Canada about 10 callouts per year ($900) plus the month cost of the line ($87 or $1,044 per year) <br />for a total of $1,944 per year. <br />l3:\GregS\Water\6ooster Station Anfcnna'I'owcr.doc <br />
