§ 24-39. Policy on water main extensions and replacements.
(a)
It is the policy of the city that all water main extensions and replacements, including water mains to be extended or replaced by the city, be constructed and sized to provide the appropriate quantity and pressure for consumption and fire protection.
(b)
It is the present policy of the city that the minimum size of a water main extension is eight (8) inch[es] and that a water main is replaced with the same size except that eight (8) inch[es] is the minimum size.
(c)
It is the present policy of the city that water main extensions larger than eight (8) inch[es] or replacements that are larger than the size being replaced except for eight (8) inch[es], may be eligible for an oversize agreement in which the city pays the difference in materials for the larger water main.
(d)
City staff has investigated and determined that to better protect the public safety, health and welfare and to provide the appropriate levels of fire protection services, larger water mains will need to be required.
(e)
Developers should be responsible for providing water mains to adequately serve the area to be developed or the development of areas to a higher use without subsidization from water customers outside the area being developed.
(f)
The minimum size for water mains within low to moderate density residential areas, as shown on the City of Effingham Future Land Use Map, as amended from time to time, shall be eight (8) inch in size. The minimum size for water mains in high density residential, commercial, industrial or business areas, as shown on the City of Effingham Future Land Use Map, as amended from time to time, shall be ten (10) inch in size. If a water main extension to serve a low to moderate density residential development passes through an area shown as high density residential, commercial, industrial or business, on the City of Effingham Future Land Use Map, as amended from time to time, the minimum size for water mains shall be ten (10) inch[es], with the portion in the low to moderate density residential area to be subject to an oversize agreement This policy shall also apply to water mains extended or replaced by the city.
(g)
All water main plans shall be submitted to the fire chief for review and written approval with respect to the appropriate location and spacing of fire hydrants. Generally, the spacing for the fire hydrants shall by every three hundred (300) feet in high density residential, commercial industrial or business areas and every five hundred (500) feet in residential areas.
(h)
All water main plans shall be submitted to the director of the department of public works for review and written approval with respect to alignment, layout, fitting schematics and protection from sanitary and storm sewers.
(i)
All water main plans shall be submitted to the director of the department of public works for review and written approval.
(j)
The city engineer shall review the plans for conformance to IEPA rules and regulations and confirm the approval by the fire chief and the director of public works prior to submission to the IEPA. The city engineer shall also confirm that the necessary right-of-way easements, IDOT or other highway authority permits have been acquired. The city engineer shall submit the plans and construction permit application to the IEPA.
(k)
A signature block for the approval of the fire chief, director of the department of public works and the city engineer shall be provided on the cover sheet of the plans.
(l)
The following statement shall be provided on the cover sheet of the plans:
"These water main plans are not for construction until all the necessary City Officials have approved the plans by affixing their signatures to the plans, the IEPA Permit Number is included below and the NPDES Stormwater Discharge Permit Number (if applicable) is included below."
(m)
In the event a water main project requires a permit, approval or sign-off of the Illinois Department of Natural Resources, Illinois Historical Preservation Agency or other governmental agency, a copy of the permit, approval or sign-off shall be filed with the city engineer.
(n)
Upon receipt of the IEPA Construction Permit, IEPA NPDES Stormwater Discharge Permit (if required) and any other required local, state or federal permits or approvals, construction may commence. No deviations to the plans will be allowed unless a change is approved in writing by the appropriate city official with respect to the nature of the change. Any deviation shall also be submitted to the IEPA to determine if a construction permit modification is needed and if so, it is acquired before the specific work commences.
