Residential & Commercial Cistern & Reservoir Services
From 100 Gallon water cisterns in a garage or basement, all the way to 2.5 Million Gallon reservoirs (and everything in between!) Alpine Water Works is equipped to handle all of your water storage facility cleaning, sanitizing and repair needs.
Our Cistern cleaning and sanitizing service consists of:
Assess the topography around the cistern, ensuring that there is no surface water infiltration, ensure the cistern lid meets code and is intact
Turn off the well and cistern pumps.
Remove the lid and vacuum out the remaining water
Using the required Confined Space procedures, enter the tank and inspect the interior for cracks or flaws. (Our team is trained in the required safety procedures and will test the air quality to ensure that it is safe to enter the tank)
If applicable, any necessary repairs would be completed
Remaining water, sludge and debris is vacuumed out, using our truck-mounted vacuum system
The interior is power washed at 3,000 psi, all wash water is vacuumed out
The tank’s interior is coated with a chlorine solution for disinfection. The interior is then power washed and vacuumed again
If applicable, the well pump is activated and allowed to fill the cistern. The cistern pump will not be turned on as not to leave it running dry while the cistern is refilling.
Depending upon the flow rate of the well and the volume of the cistern, it is advised that a water hauling company be contacted to fill the cistern, so undue stress is not placed on the well.
The 2 most common sources of contamination in your cistern are from a) surface water and b) ground water.
Alpine Water Works trained staff can repair all types of cisterns and water tanks, including concrete, fiberglass, plastic and metal.
