The following water restrictions will be in effect for the 2010 irrigation season. Beginning April 15, 2010, and running through October 15, 2010, outside watering between 10.00 am. And 4.00 pm will not be permitted on any day. The even, odd watering days stay in place, as they do year round. This means if the last number of your street address ends in an even number you may water on even numbered calendar days. If the last number of your address ends in an odd number you may water on odd numbered calendar days. On the 31st day of the month outside watering is prohibited.
I would also like to take this opportunity to talk about routine bacteria sampling that occurs within the water distribution system. We are required, based on population to take seven bacteria samples per month. The samples are taken at sites predetermined by a sampling plan. The plan contains twenty one routine sampling sites with seven alternate sites. If for some reason the routine site is not accessible then an alternate site is used. The sampling each month is spread through out the system rather than being concentrated in a certain area. Each site by years end will have been tested four different times.
The water distribution system contains many miles of piping to get the treated water to its customers. Chlorine residual is maintained throughout the distribution system to assure a level of water quality. Chlorine levels are tested every time a water sample is collected. They are also tested at every treatment point daily and at the surface water plant continuously. A predetermined site within the distribution system is also tested daily.
Another important aspect to distribution water quality is a good flushing program. This part of system maintenance is often mistaken by the public as a waste of water. Flushing rids the system of accumulated sediment and discolored water. Flushing also gets rid of old water, water that’s been in the system for periods longer than normal. This can occur in areas with lower usage or dead end lines. Getting old water out of your system reduces the potential for the formation of disinfection by products. The whole treatment process and delivery is a balancing act, where each process may have an effect on the other.
One of our major projects scheduled for this year is the Reservoir roof replacement, which is currently under construction. The built up roofing material has been removed and a new single ply roofing system will be installed.
Removal of the old roof was completed last week and as anticipated some concrete patch work will be required before the new roof is installed. Eight areas along the outside perimeter of the tank have been targeted for repair. These areas are small in scope considering the tank is 210feet long and 157 feet wide. One exterior support beam will also receive minor repair work.
A new access hatch and one additional vent will also be installed as part of the project. The new hatch will require a larger opening. The larger access size will accommodate easier material handling, when the interior upgrade to address leakage, begins this fall.
