Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
153 words
A computer implemented method for managing a public utility wastewater collection system, the steps of which comprise: (a) establishing a computer-accessible database, the database including wastewater collection system parameters, the collection system parameters including pipe system parameters comprised of the location, with respect to a coordinate system, of sewer pipe and manholes, the elevation of the pipe and manholes, and pipe and manhole diameter; and the collection system parameters including predicted customer wastewater input into the system along the pipe; (b) selecting an area of the wastewater collection system for analysis; (c) selectively reviewing portions of the database information related to the selected area; (d) selectively modifying database parameters; (e) determining at least one wastewater flow for a portion of the pipe system under analysis; (f) determining at least one surface hydraulic grade for a portion of the pipe system under analysis; and (g) comparing the surface hydraulic grade against a predetermined criteria.
Claim 2
Dependent Claim
153 words
A computer implemented method for managing a public utility wastewater collection system, the steps of which comprise: (a) establishing a computer-accessible database, the database including wastewater collection system parameters, the collection system parameters including pipe system parameters comprised of the location, with respect to a coordinate system, of sewer pipe and manholes, the elevation of the pipe and manholes, and pipe and manhole diameter; and the collection system parameters including predicted customer wastewater input into the system along the pipe; (b) selecting an area of the wastewater collection system for analysis; (c) selectively reviewing portions of the database information related to the selected area; (d) selectively modifying database parameters; (e) determining at least one wastewater flow for a portion of the pipe system under analysis; (f) determining at least one surface hydraulic grade for a portion of the pipe system under analysis; and (g) comparing the surface hydraulic grade against a predetermined criteria.
Claim 3
Dependent Claim
50 words
The method of claim 1, wherein the pipe system parameters include the location of waste treatment facilities along the pipe system and the back pressure on the pipe from the facility and the location of pumping stations along the pipe, and the head pressure on the pipe from the station.
Claim 4
Dependent Claim
59 words
The method of claim 2, wherein the collection area is subdivided into service areas by waste treatment facility and wherein the service areas are divided into subservice areas, the boundary of the service area and subservice area being defined by the pipe system and the wastewater customers of the pipe and being part of the wastewater collection system database.
Claim 5
Dependent Claim
26 words
The method of claim 3, wherein the user limits analysis to a portion of the collection area by limiting analysis to service areas or subservice areas.
Claim 6
Dependent Claim
21 words
The method of claim 4, wherein the pipe system parameters include the infiltration input and inflow input along the pipe system.
Claim 7
Dependent Claim
22 words
The method of claim 5, wherein the pipe system parameters include the material of the pipe and the roughness of the pipe.
Claim 8
Dependent Claim
103 words
The method of claim 6, wherein the wastewater collection system database includes the location of arbitrarily defined area polygons wherein the polygon area data includes the number and types of wastewater system customers in the tract; wherein the database further includes the estimated input into the pipe system for each wastewater customer type; and wherein the customer wastewater input into the system along the pipe is predicted from the census data and the data of estimated input per type; and wherein the predicted customer wastewater input into the system along the pipe is allocated to the subservice areas that overlap the census tract.
Claim 9
Dependent Claim
13 words
The method of claim 7, wherein the arbitrarily defined polygons include census tracts.
Claim 10
Dependent Claim
15 words
The method of claim 8, wherein the allocation is pro rata based upon relative area.
Claim 11
Dependent Claim
13 words
The method of claim 9, wherein the census data includes forecasted census data.
Claim 12
Dependent Claim
15 words
The method of claim 10, wherein the census tracts are comprised of municipal zoning areas.
Claim 13
Dependent Claim
24 words
The method of claim 11, wherein the pipe system parameters include the location of major easements and rights-of-way in the wastewater collection system area.
Claim 14
Dependent Claim
22 words
The method of claim 12, wherein the pipe system parameters include the location of major thoroughfares in the wastewater collection system area.
Claim 15
Dependent Claim
46 words
The method of claim 13, wherein the user reviews portions of the database by means of a map graphic display that includes locating, by coded color and symbol, service area boundaries and subservice area boundaries, pipe, manholes, water treatment facilities, pumping stations, and census tract boundaries.
Claim 16
Dependent Claim
22 words
The method of claim 14, wherein the map graphic display includes locating by coded color and symbol major thoroughfares, easements, and rights-of-way.
Claim 17
Dependent Claim
28 words
The method of claim 15, wherein each pipe segment, manhole, waste treatment facility, pumping station, service area, subservice area, and census tract is uniquely identified by a symbol-name.
Claim 18
Dependent Claim
21 words
The method of claim 16, wherein the user reviews portions of the database by reviewing the data associated with a symbol-name.
Claim 19
Dependent Claim
31 words
The method of claim 17, wherein the user modification of portions of the database includes removing or adding pipe and manholes and altering the boundaries of service areas and subservice areas.
Claim 20
Dependent Claim
34 words
The method of claim 18, wherein the user modification of portions of the database includes adding, deleting, or changing wastewater collection system data, including census data and estimated wastewater customer input per customer type.
Claim 21
Dependent Claim
27 words
The method of claim 19, wherein the computing of at least one wastewater flow figure includes computing a wastewater flow figure for each subservice area under analysis.
Claim 22
Dependent Claim
17 words
The method of claim 20, wherein the database includes previously calculated wastewater flow figures for subservice areas.
Claim 23
Dependent Claim
29 words
The method of claim 21, wherein the customer wastewater input to the system along the pipe for a subservice area is assigned to one manhole within the subservice area.
Claim 24
Dependent Claim
26 words
