Agawam Green Residential Development - Wareham MA

041128 - Cran Crt - WWA - ReportWastewater Alternatives was asked by the project applicant to prepare an alternative analysis for a residential development that was proposed in a nearby community. The project consisted of 48 dwelling units with a wastewater design flow of 9,900 gallon per day.  The project proponents had a desire to include environmentally sustainable programs into their development plan including an alternative wastewater management approach.

4Once the applicant decided on the conventional wastewater management approach Wastewater Alternatives developed plans and specification for the local permitting process and construction of the project. The project included a septic tank effluent gravity (STEG) sewer system with pressure distribution of this effluent to subsurface dispersal trenches. The wastewater management plan was approved by the Wareham Zoning Board of Appeals and the Wareham Board of Health and is anticipated to be constructed in 2008.

White Farm Residential Development - Norton, MA

Wastewater Alternatives prepared final plans and specifications that were prepared for Norton Board of Health approval and system construction. The plans 6included an innovative aerobic treatment technology in the form of a Modified Trickling Filter called BioClere.  Inclusion of this system was a requirement of the Norton Planning Board which mandated a total effluent nitrogen concentration limit of 16 mg/L to comply with their site specific nitrogen loading requirements. The BioClere system was selected because of its documented use in Massachusetts at projects similar to the White Farm project and meeting the 16 mg/L total effluent nitrogen limit.

It is important, and became a requirement of permitting this system for the project, that plans and specifications be clear, thorough and concise so that contractors can install a system that will work as intended.  Wastewater Alternatives prepared a very thorough and detailed plan and specification package for the project to ensure proper installation of the system, that will meet the effluent quality limits assigned to the project and will minimize construction and operation and maintenance cost overruns. The project received final regulatory approval in February 2007 and is slated for construction in the spring-2008.

Cranberry Village Residential Development - Middleborough MA

8Sometimes the best wastewater management strategy for certain projects is connection to a municipal wastewater treatment plant through a state sewer extension permit. This was the case for a proposed residential development slated for constructed in the Town of Middleborough. The development is expected to generate more than 50,000 gpd of design wastewater flow at build-out and includes 120 two and three bedroom dwellings units and 96 two bedroom apartments offering affordable living spaces to the region which includes the South Shore, South Coast and the Cape Cod areas. 
Disposing this volume of wastewater onsite would have been challenging considering local protected water resources and site limitations which included shallow depth to groundwater. Faced with this the applicant looked to Wastewater Alternatives, L.C. to develop plans and specifications to permit and construct a sewer extension for the project.

The design included a 2,400-foot gravity sewer, a pump station and a 5,000-foot force main that transports wastewater from the project to the Middleborough municipal wastewater treatment plant through a municipal gravity sewer. The project received approval of the Sewer Extension Permit Application from the Massachusetts Department of Environmental Protection in April 2007 and is anticipated to be constructed in 2008.

Cambridge School of Weston Science Art Center - Weston, MA

050331 - WWA - Report

Part of the school’s Master Plan included the construction of a facility that would consolidate all science instruction into one building and present an opportunity to integrate their art programs with the sciences. This became the basis from which the Science and Art Center project has evolved.   The school has committed themselves to providing ecologically sustainable15 methods for all new construction on the campus including the Science and Art Center and that became the primary theme of the wastewater management plan.

To guide the school community through the wastewater treatment and disposal system selection process Wastewater Alternatives developed a detailed alternatives analysis. This report included a thorough evaluation of various wastewater treatment options including aerobic treatment units and composting toilets.

18Our report included conceptual layouts, process flow diagrams and a complete cost analysis that included operations and maintenance costs for each alternative. Although not the least expensive option, the school was very attached to the ecologically sustainable feel of composting toilets and therefore decided to move forward with that option. Wastewater Alternatives has recently completed final plans and specifications for this project and was constructed in the summer of 2007 and is now fully operational.

Dighton Rehoboth Regional High School - Dighton, MA

After completing the Wastewater Management Study for the High School project, the Dighton Rehoboth Regional School Committee selected Wastewater Alternatives to provide design, permitting and construction services required to implement the recommended wastewater management plan. Wastewater Alternatives developed a design manual along with plans and specifications to ensure proper installation and implementation of the recommended plan with contract bids scheduled for spring-2008 and construction of both the wastewater treatment and dispersal upgrade and non-sanitary waste system schedule to be complete during the summer of 2008.23

This is a large project that requires significant funding.  Most school districts don’t have the funds required for a project like this included in annual budgets and this was the case for this 20project.  With that in mind Wastewater Alternatives worked with the District’s Business Manager to obtain alternative funding for the project.

The approach was two fold; first we looked to fund the project under the State Revolving Fund, a low interest loan program administered by the Massachusetts Department of Environmental Protection; as well, the business manager applied for grant funding from the Massachusetts School Building Authority.

Both funding approaches proved successful; the project has been placed on the 2008 Clean Water State Revolving Fund Project Priority List which ensures full project funding and, while a grant amount has not been determined by the time of this writing, the District will be awarded a grant from the Massachusetts School Building Authority.
