4Problem Identification
- Puddles on the University Mall make travel
inconvenient for pedestrians and are
aesthetically unappealing - Improper grading of the Mall
- Lack of drainage to move surface water away from
Mall - Discharge into Stillwater River does not meet DEP
standards and regulations - Increase in impervious areas on campus
- Editorial published in Maine Campus on October
27, 2005 We Need to Clean Up Our Ugly Mall

8Phase I
Drainage Improvements on The UMaine Mall
- Perform hydraulic analysis of the Mall
- Install French Drains along pedestrian walkways
for storm water runoff collection - Tie French Drains into the current storm water
collection system that exists in Drainage Region
5 - Regrade the Mall to facilitate drainage of
surface water towards the French Drains
9Hydraulic Analysis of The Mall
- Land area 4 acres
- Obtained data from USDA TR-55 Method (Developed)
- 2-Year Event gt 4.2 ft³/s
- 10-Year Event gt 7.4 ft³/s
- 25-Year Event gt 9.2 ft³/s
- Discharge to be used in French Drain Design based
on 25-year event gt 9.2 ft³/s
10Install French Drain and Regrade the Mall
- French Drain Dimensions
- 18 wide x 24 deep
- 1800 linear feet of 6 perforated pipe
- 2 slope from center of Mall towards French
Drains
11Tie French Drain System into Existing Drainage
Structure
- Use two Type F catch basins to tie French Drain
system into existing
12Phase I Cost Analysis

15Hydraulic Analysis of UMaine Storm Water Drainage
Region 5
- Land area 20 acres
- Obtained data from USDA TR-55 Method (Developed)
- 2-Year Event gt 21 ft³/s
- 10-Year Event gt 37 ft³/s
- 25-Year Event gt 46 ft³/s
- Discharge to be used in retention and treatment
design based on a 25-year event gt 46 ft³/s
16Water Treatment Facility
- Used 25-year storm event storage volume to design
a Vortechs water treatment facility - Vortechs Model 1000
- 9 long x 6 wide x 7 deep
- Removes sediment, trash, free oil grease
17Water Retention Facility
- Used 25-year storm event storage volume to design
retention facility with Rainstore³ Estimator - 13,557 units
- Chamber size gt 95 x 128 x 4 deep
- Capacity of 45,000 ft³ of water (336,000 gallons)
- Obtained design details and technical
specifications from Rainstore³ site - Place Rip Rap around opening of outlet pipe to
prevent erosion
1894 Void space provides 25 gallons of water
storage per unit
