Drain Fields

After the wastewater is treated in the treatment tank, it passes through the chlorinator, and into either the chlorination tank or the pump tank.

Chlorination tank – the tank is designed to hold the chlorination effluent for a certain length of time and then gravity flow out onto the top of the ground. During this time, the chlorine kills any remaining bacteria, pathogens, etc. and then breaks down for safe release onto the ground. Please note that there is a special wastewater grade chlorine used for this purpose. Pool chlorine is not designed for use in a wastewater chlorination tank and will not break down in the same amount of time. This will cause a dead zone at our discharge point.

Pump tank – this tank is designed to hold the chlorinated effluent for a certain amount of time and then pump it out to the discharged onto the ground via a single pipe or a spray field. The spray field will have multiple discharge points using spray heads to spray the chlorinated effluent over a large area on top of the ground. As described earlier, if you use the wrong kind of chlorine in your chlorinator, it could cause a large dead zone around these spray heads.

Drip system – a drip system is used to discharge the effluent underground instead of on top of the ground. These systems are generally used on small lots. They are expensive and require on-time maintenance. For this reason, they are considered a last resort system and not used very often. If you think that you would like to used this type system, you first need to consider the $8,000 to $15,000 price tag.
