The complex is presently served by six sewage disposal sytems. Five of the six systems were designee'and/or conditioned by Massachusetts Department of Public Health permits to conform in general with the requirements of Title V: the Massachusetts State Environmental Code for subsurface disposal of sanitary sewage. Specific design information on the sixth system that presently serves two units of the building situated in the northeast portion of the site could not be found. Based upon the configuration of the system shown on a plan dated May 16,1989,from Down Cape Engineering,the theoretical leaching capacity meets the Title V flow requirements of the two rooms served. The following is a description of the systems based on a compilation of record information. \^r 1. The design plans for Systems 1 and 2 were prepared by Everett Hinckley and dated September or 1979. Each system consists of a 2250-gallon septic tank and a leaching field with 1620 square or feet. The leaching facilities were installed to replace a facility constructed in 1970±. The theoretical flow capacity of the twe leaching facilities is 3240 gallons per day. 2. System 3 was reconstructed in 1976 based upon design plans prepared by Down Cape Engineering dated April 19,1976. Based upon the plans and Massachusetts Department of Pone Health conditions,the system consists of a 3000-gallon septic tank and a 32.4-foot by 67- foot leaching facility. The theoretical flow capacity of the System 3 leaching facility is 2170 gallons per day. 3. System 4 was reconstructed as a repair in 1989. Based upon design and as-built plans prepared by Down Cape Engineering dated May 16 and June 15,1989,respectively,the installation utilized the existing 3000-gallon septic tank and a new leaching facility with a bottom area of 1420t square feet. The theoretical flow rapacity of the System 4 leaching facility is 1420 gallons per day. PMibd on reeved pacer 7_'d 002.9SSEBaS 9tJIJ331,1I91J3 ltl1St0D TO:ST P6, in 03Q Mr, Bruce Murphy Page Two December 1, 1994 4. System 5 consists of one 8000-gallon septic tank, a pump chamber, and two leaching facilities with 2700 square feet of bottom area each. The pump chamber and leaching facilities were installed based upon design plans prepared by Charles D. Spohr In May of 1970. The theoretical combined flow capacity of the leaching facilities is 5400 gallons per day. 5. Record design plans for System 6 could not be found. Based upon the system configuration shown on a plan dated March 16, 1969, by Down Cape Engineering, the system consists of a septic tank and 20»foot by 28•foot leaching facility with an estimated capacity of 560 gallons per day. e The Blue Water Resort presently consists of three buildings that include 81 rooms,guest a 138-seat �\`-' �ef restaurant, and a 40-seat lounge. The estimated Title V sewage flow for the present facility is 14,540 gallons per day. The proposed redevelopment of the site includes reducing the number of seats in the restaurant by 30, which would reduce the estimated Title V sewage flow to 13,490 gallons per day. The estimated total capacity of the leaching facilities that presently serve the complex is 12,970 gallons fir day, nr 94.8% of the estimated reduced sanitary flow. Area is available for the future upgrade of the systems in a 25,000-square foot reserve area located on the resort property on the north side of South Shore Drive as designated in 1970 by the Massachusetts Department of Public Health. Additional reserve area will be available on Edge of the Sea Motel land to be conveyed to the resort. A 3ei1 percolation rate of 2 minutes per inch was used in the review of the system plans based upon record soil tests performed on the project site and other properties in the area. Based upon our review of record information, Systems 1, 2, 3 and 5 were designed or conditioned by permit to provide a minimum of four feet separation between the bottom of the leaching facility and groundwater. As-built plans for System 4 indicate a 3.05-foot groundwater separation is provided. Insufficient information was available to determine the groundwater separation for System 6.
