Bulk Water Stations

Northwestern Water & Sewer District understands the need for quality potable water in rural areas beyond the reach of existing water lines. To help fill this need, The District has installed a number of bulk water stations throughout the region where customers can buy water in bulk to fill tanks or cisterns. The District’s bulk water stations primarily supply commercial and agricultural users with thousands of gallons of water to be hauled for use in filling pools, cisterns, construction use, and farming. Water haulers can contact The District at (419) 354-9090 Option 2 or email The District to set up an account.

Bulk Water Dispensing Units

Users can access bulk water with a user-friendly pin pad.

To Use the Dispensing Unit:

  1. Enter your user number – press enter
  2. Enter the PIN number – press enter (same number for both entries)
  3. Enter the quantity of water you will be dispensing (50 gallons is the minimum amount)
  4. Enter pump number 1
  5. Turn the switch to the on position – the pump will shut off automatically once your quantity of water is dispensed
  6. Please turn the switch back to the off position

Safe Potable Water

Water from our bulk water stations is safe for personal uses such as filling pools, filling cisterns. It is also available for commercial and agricultural use. The water stations employ modern technology and safe equipment such as backflow prevention devices to protect against contamination during filling and loading.

Safe Off-Road Access for Trucks & Trailers

Each bulk water dispensing site has been chosen to provide safe access for large trucks and trailers. The driveway at each site is designed to handle farm trucks, trailers, and tractor-trailer tankers with plenty of driveway turning radius.

Buy Water in Bulk

  • Water costs $12 per 1,000 gallons purchased. Quantities less than 1,000 gallons will be billed at $12.


Your account is billed monthly, with all bills due by the middle of the following month. Bulk water bills are generally due around the 8th of every month.

Accounts will be billed a late fee if paid past the due date.

A one-time new customer fee of $25.00 is added to the first or second bill.

The District’s fill station has a 3-inch male Camlock fitting. Each hauler is responsible to adapt their equipment to fit the District’s outlet using a 3-inch female cam-lock fitting.

Your vehicle must be plumbed with an air gap with prior inspection by District personnel.  Your equipment air gap needs to be 2 times the diameter of the fill pipe. For example, if the fill pipe is 3-inches, your air gap needs to be 6-inches or more. Also, all water hauling tanks/equipment must be inspected yearly to continue utilizing the fill terminals.

Air Gap Examples

The following photos display tanks with an air gap 2 times the diameter of the pipe:

Bulk Water Station Installation Requirements

Installation Requirements
  1. Any backflow preventer must be installed inside the building unless The District approves an alternate location.
  2. The backflow preventer must be installed immediately downstream of the water meter, if the water meter is in a pit then the backflow preventer must be installed immediately as the service piping enters the building.
  3. The service piping between the meter and the backflow preventer must be void of branches or outlets of any type.
  4. The backflow preventer must be installed a minimum of 6 inches from the wall and 18 to 24 inches from the floor.
  5. The backflow preventer must be installed in a horizontal plane.
  6. All test cocks must face the center of the room unless they are mounted in the top or bottom of the assembly.
  7. The backflow preventer may be no smaller than the water meter size unless a manifold or parallel setting of backflow preventers is installed.
  8. If a manifold or parallel setting is installed, then the combined flow rate of the assemblies must equal or exceed the flow rate of a single assembly setting.
  9. The backflow preventer must be of a type approved by the Ohio EPA and the Northwestern Water and Sewer District.
  10. Water will be spilled during the normal operation of a reduced pressure backflow preventer and during the periodic testing of all backflow preventers; for this reason, it is recommended that a floor drain be installed as close as practical to the assembly.
  11. The relief valve discharge of a reduced pressure backflow preventer may be piped to a floor drain provided an approved air-gap separation is maintained at the point of connection to the relief valve discharge.
Air-Gap Separation

Must be at least 2 times the nominal diameter of the discharge piping but never less than 1 inch.

A physical separation through the free atmosphere is measured from the opening of the discharge piping to the flood level rim of the receiving vessel.

Thermal Expansion Control

The Ohio Basic Building Code, Plumbing; Section 607, “Hot Water Supply System”, Sub-Section 607.3.2, “Backflow Prevention Device or Check Valve” specifies that:

“Where a backflow prevention device, check valve or other device is installed on a water supply system utilizing storage water heating equipment such that thermal expansion causes an increase in pressure, a device for controlling pressure shall be installed.”

Thermal expansion of heated water will occur wherever potable water is heated in a cooling system. Uncontrolled thermal expansion usually results in leaking faucets or burst washing machine supply hoses, but may result in a collapse of the vent pipe on gas-fired water heaters, or violently burst water heaters in extreme cases.

An expansion tank is one method (other methods are available to refer to plumbing code) designed to absorb thermal expansion that will be created by the hot water heater, if the water user’s potable system is closed with a containment principle backflow prevention assembly, a check valve or a pressure reducing valve without an internal bypass.

The expansion tank must be installed in the cold water service piping on the supply side of the hot water heater prior to any control valves. The size of the expansion tank is based on the size of the hot water heater and may be determined by referring to the manufacturer’s recommendations.
