| Design Calcs. For Alternative Design: Falcutative Lagoons | ||||||||
| Client: Village of Sipaulovi, AZ | ||||||||
| Design Criteria: | ||||||||
| ∙ Minimum 2 lagoons in series, w/ 2-parlallel systems recommended | ||||||||
| → #lagoons = | 2 | |||||||
| ∙ Detention time (min.) = | 20 | days | ||||||
| ∙ Lagoon depth (min.) = | 3 | ft | ||||||
| ∙ Design flow = | 0.097 | mgd = | 97000 | gals | ||||
| SOLN: | ||||||||
| Vol. = detention time X Qflow = | 259,358 | ft³ | Reqd. Vol. of Pit | |||||
| Areareqd Depth = | 3 | ft = | 86,453 | ft² | Area Req'd | |||
| Area Req'd for each lagoon = | 43226.4 | = | 43,227 | ft² = | 0.99 | acre | ||
| Total Area Req'd for 2-Lagoons = | 2.0 | acres | ||||||
| Note: 1 lagoon is off-line. | ||||||||
