The city interviewed four engineering firms and selected The Larkin Goup in a tight evaluation. City and Engineers developed separate wwtp evaluations against Schreiber, SBR, Eimco, and Aeromod. Initial city engineer evaluations suggested Aeromod in 1999. Year 2000 evaluation provided site visits, construction costs, and O&M Costs for all the faciliities above. The evaluation provided AEROMOD and SCHREIBER as the two to evaluate on O&M Costs. Schreiber dual GR basins were more economical to construct and but the existing city plant is an AEROMOD.
O&M Costs proved to be more economical for Schreiber to be a lower electrical cost by $2,000 per month or approx $1 per person connected in 1999 per month. That is more than the city was able to accept, the decision was to build a Schreiber dual GR unit.
After some site evaluations, a 25% larger system was built for only a small construction cost adder for one additional foot of side wall height.
City demands for opertor friendly were intense and engineering creativity was needed. Site constraints were physically tight and rock was shallow. Influent pump station is 30' deep for 30" gravity interceptor connection.
