CLEARSTREAM TANK INSTALLATION

1. Prepare an excavation having minimum dimensions of at least one (1) foot larger than

the dimensions of the tank. Make sure the depth of the excavation is deep enough to allow

gravity flow to the inlet of the system and that the excavation bottom is level. Never install

the Clearstream tank deeper than a depth that will require more than a maximum of 18

inches of riser depth.

installation. In applications where more than the maximum 18 inches of riser is required,

install a lift pump upstream of the Clearstream tank to pump the pretreatment tank effluent

to the Clearstream tank at normal grade. In these special applications where a lift pump is

required, contact Clearstream for more details as to pump size, maximum dosages and

maximum flow rates.

2. Set the Clearstream tank in a prepared excavation that has a solid, level bottom that will

eliminate tank settling.

present.

3. When lowering the concrete tank into the prepared excavation use a spreader bar. Only

spreader bars and other lifting devices, that have been designed and tested for lifting

Clearstream concrete tanks, should be used. Never lift concrete Clearstream tanks unless

they are empty of all liquids.

4. Make sure the inlet 4" PVC pipe is aligned properly to incoming sewage line.

5. For the Clearstream Unit to function properly, the tank must be level. To properly level

the tank, lay a three (3) foot level across the tank in several directions. Shift the tank in the

hole, as necessary, to make the tank level in all directions. The tank may be slightly out of

level, but it should not be out of level enough to cause tank malfunctions.

6. Fill the tank with fresh water, checking periodically to make sure the tank remains level.

7. Connect the 4" PVC Clearstream inlet pipe to the incoming sewage line. Make sure the

incoming sewage pipe is level with or higher than the inlet pipe to the Clearstream Unit.

The Clearstream Unit should only be connected to a plumbing system from a

wastewater source which has been properly trapped and vented in compliance with State

and Local plumbing codes.

8. Back-fill the excavation in layers with back-fill material that will settle properly around the

tank. Tamp the back-fill material as each layer is placed around the tank. If necessary, use

water to help settle the soil around the tank. Special care should be taken to either tamp

soil under where inlet and outlet pipes are bridging the excavation or use some other method

of supporting pipes across the excavation. Do not back-fill with heavy chunks of clay or large rocks.

9. Before completing the back-fill, be sure the electrical conduit from the tank to the Control Panel and

the air line from the aerator to Clearstream Unit has been laid underground.

The access cover shall always be above final grade after tank

The excavation bottom should have no rocks or sharp objects
