The applicant shall be responsible for providing an approved wastewater system, consistent with the preliminary plan, this chapter and the rules and regulations of the entity providing or to provide wastewater service to the development, throughout the development, such that all lots, parcels, or tracts of land will be capable of connecting to the wastewater system except as otherwise provided herein.
(1) 
Where an approved public wastewater collection main is within reasonable distance of the subdivision as determined by the Director of Engineering or his/her designee and connection to the system is both possible and permissible, the developer shall be required to bear the cost of connecting his development to such existing wastewater system and the acquisition of all necessary easements. In some instances, the city may request that the main wastewater connection be oversized or rerouted to suit future wastewater system improvements in that area. In some cases, the city will reimburse the applicant the costs of oversizing or rerouting such connections.
(2) 
The applicant shall, consistent with all existing ordinances, make a pro-rata contribution to funding of needed lift station facilities, treatment facilities, and specific collection lines as determined necessary by the city. Under extraordinary circumstances, these provisions may be varied with the approval of the council and the Planning and Zoning Commission.
(Ordinance CO42-07-07-12-3I adopted 7/12/07)
(a) 
The design and construction of wastewater collection systems, lift stations, inverted siphons and septic systems shall comply with regulations covering extension of public wastewater systems, and other applicable regulations, adopted by the state commission on environmental quality and the state department of health. Under extraordinary circumstances, these provisions may be varied with the approval of the council and the Planning and Zoning Commission.
(b) 
All new public wastewater systems shall be designed and constructed to operate on a gravity flow basis by taking advantage of natural topographic conditions and thereby reducing the need for lift stations and force mains.
(c) 
Flow determinations should include generally accepted criteria for average daily flow, inflow and infiltration, peaking factors, minimum slopes and minimum flow velocities.
(d) 
The minimum size of any public wastewater line will be six (6) inches in diameter.
(e) 
Public wastewater lines shall be located where maintenance can be accomplished with the least interference with traffic, structures and other utilities. Minimum separation distance from water utilities shall be in accordance with the rules adopted by the state commission on environmental quality.
(f) 
Manholes shall be located so as to facilitate inspection and maintenance, including intersections, horizontal alignment changes, vertical grade changes, change in pipe size or material, and force main discharge points.
(g) 
All wastewater appurtenances shall be designed and constructed in accordance with city standard details and specifications.
(h) 
All wastewater systems shall be designed and constructed to comply with all applicable rules, regulations and policies of the entity that will provide wastewater service to the development.
(i) 
The wastewater system shall be constructed across the entire frontage of the tract or to the edge of the tract so as to allow future extensions of the wastewater system by adjacent tracts. A waiver to this requirement shall be in writing from the Director of Engineering or his/her designee.
