Abstract: A system for flushing a conduit having an inlet, an outlet, and at least one flow restricted outlet between said inlet and said outlet. There is a pump operative to periodically be turned on and off for pumping a liquid from a liquid source to the inlet, a pressure pulse being generated when the pump is turned on. A hydraulically actuated indexing valve has an inlet connected to the second outlet end of the conduit, the indexing valve including a valve element assembly indexable between a plurality of indexed positions in response to a plurality of pressure pulses, wherein in at least one of the indexed positions, return flow from the second outlet end of the conduit flows through the outlet of the valve to increase flow rate through the conduit.

Abstract: A mobile wastewater treatment system wherein a mobile carrier has mounted thereon a wastewater treatment plant. The wastewater treatment plant has a flow equalization tank, an aeration tank, a clarifying tank, a disinfection stage, and a pumping tank. The mobile carrier can be a trailer, a skid, a shipping container, or the like.

Abstract: An aerobic treatment/clarifying system for use in an aerobic wastewater treatment system. The system comprises a structure which defines at least one compartment, at least one aerobic treatment chamber and at least two clarifying chambers being formed in the compartment.

Abstract: A sparse data system determines regulatory compliance of a plurality of small environmental systems that utilize a respective plurality of pumps. Each environmental system utilizes a universally programmed dialer configured to receive, store, and transmit pump operation data. A server is configured to utilize the time of operation of the pumps and separately provided installer information such as installer determined pump flow rates and permitted thresholds of operation of the environmental systems to provide a regulatory body with processed data indicative of whether the environmental systems are in compliance with their permitted thresholds. The dialers limit the number of connections with the server to periodically connecting to the server only after a predetermined time period or predetermined events.

Abstract: A mobile wastewater treatment system wherein a mobile carrier has mounted thereon a wastewater treatment plant and a pump tank. There is a pump disposed in the pump tank, the output in the pump being selectively directed to a human use facility. Discharge from the human use facility is transferred by gravity to a lift station, accumulated wastewater at the lift station being transferred to the input of the wastewater treatment plant.

Abstract: A riser section having a generally tapered, e.g., frustoconical wall, the riser section having a first connector assembly at one end of the riser section and a second connector assembly at the other end of the riser section.

Abstract: Embodiments of the invention are directed to apparatus, methods, and computer program products for using a preferred rewards program. In some embodiments, the apparatus is configured to receive information associated with a user's financial institution account on the last day of a current month, wherein the information comprises a monthly asset balance; determine an average asset balance based on generating an average monthly asset balance for at least two months prior to the current month; categorize the user, based on the average asset balance, to determine which of a plurality of status levels is applicable to the user, wherein the plurality of status levels is based on an asset balance range; identify an existing payment card associated with the user; and apply a benefit associated with the categorized status level to the user's existing payment card.

Abstract: An apparatus for use in a septic system such as an aerobic wastewater treatment plant connected to a drip irrigation system for dispensing wastewater from the septic system. The apparatus includes a pump having a pump outlet for a pumping treated wastewater from the septic system, a filter connected to the pump outlet, the filter having a first output for directing filtered water to the drip irrigation system and a second outlet for disposal of backwash water used to clean the filter. There is an accumulator or canister having a predetermined volume for receiving water from at least one of the drip irrigation systems and the second output of the filter. The accumulator has an outlet connected to a pressure actuated normally open flush valve, which closes in response to pressure from water in the accumulator and which moves to the normally open position when the pump is deactivated.

Abstract: A system for disinfecting contaminated water having, in one embodiment, a vessel for contaminated water having an inlet and an outlet. An elongate housing is disposed generally vertically in the vessel, the housing having a housing inlet and a housing outlet, the housing outlet being in open communication with the interior of the vessel. An elongate UV light assembly is disposed in the housing and divides at least a portion of the housing into first and second flow pathways, the second flow pathway being in open communication with the housing outlet. There is a flow inducer aiding flow of at least some of the contaminated water from the vessel, through the housing and out the housing outlet.

Abstract: A sparse data system is provided for verifying operational compliance of a plurality of environmental systems. To reduce operational costs to a minimum, the quantity of data transmitted is minimized and the data is only transmitted at certain times. If systems are compliant, then information is preferably not sent. If systems are non-compliant, then notices are sent to parties of interest at effectively the same time as the noncompliance occurs. Subsequent alarm detection level may also be sent after detection of an operational threshold to provide notice for continued ongoing or severe noncompliance.
