Thank you so much for your assistance in getting this done in such a timely manner. I also see the contractor list you have included. The contractor I was planning on using is JB North Shore Construction Company out of Boxford. Contact name is John Butt. He assisted in the test holes during the design process last February and I have been planning to use him since. I believe he does work in North Andover. However, I see he is not listed on the contractor list. Would there been any problem in using him? Thank you so much!

One question came up which will need your involvement please: Your plan shows a 90 degree elbow to be built inside the distribution box for dispersement of the pumped water. The contractor built it according to your plan. What we noticed today was that the elbow is below the static water level and thus at the end of the pump cycle the force main created a seal so that the piping was unable to rapidly drain. The contractor and I had concerns about this possibly causing a freezing or siphoning problem and I wanted to review this with you. When I look at Title 5, 310 CMR 15.232(3)(a), it calls for an inlet tee, baffle or splash plate and does not speak to use of an elbow. It was reported that one of your representatives instructed the site contractor that this is the method of construction that is desired, primarily to avoid the possibility of water exfiltrating from the top seam of the distribution box if a tee were to be used that directed water up. While I can appreciate that concern, I need to ask you to please intervene by either: 1. Examining the operation of the system and attesting in a separate letter that the pump system complies with Title 5 and is operating per your specification 2. Reviewing this matter with the site contractor and developing some type of solution for this situation. One that readily comes to mind is to transition the force main from a 2" pipe to a 4" pipe near the distribution box and then place a 4" inlet tee inside the tank-this should, though I am not certain, avoid concerns about water seeping from around the distribution box lid and allow the force main to drain readily between pump cycles. Of course there may be other methods you might wish to consider as well,this is just one idea. If something different is proposed we would appreciate a quick note explaining what that approach might be and then have you depict on the as-built plan. The attached photo of the box while being dosed might assist you visualize matters. Could I ask that you please look into this matter and let me know which way you wish to proceed? If it helps,the excavation contractor can be reached at 978.815.5754 if you wish to review this with him. Thanks in advance, Dan 7/29/2015 Well Water Pumps.Measuring static water level. IMP LE f The � F f ", OUR PUMPS USES PREPAREDNESS WHY SIMPLE PUMP PRICING GET A QUOTE SUPPORT CONTACT HOME HOW TO FIND YOUR WATER. LEVEL Your static water level (often simply celled "the water level") is the Pressure discharge piping distance frorn ground level down to the water in your well. It's the "resting" level of water---i.e,when you are not pumping and haven't WELL To house CAP pumped recently. THE STATIC WATER LEVEL CAN COME FROM: sLatic 1. From your well driller's report lcvv jr If you have one from when the well was initially drilled, waell depth 2.

Measuring it yourself To determine your static water level yourself,you'll need A small steel weight,e,g,a nut P A fishing float P Fishing line or string. Measuring yourself is the last choice because there's a possibility you could get the line caught down the well. HOW TO MEASURE P Attach the weight to the end of the line or string.Attach the bobber one inch above the weight. P Remove the well cap and lower the weighted end with bobber into the well casing. r When the bobber reaches the water level,the line will go limp. — You'll feel a slack in the line. w At the point where you feel the slack,mark the line at the top edge of the casing(you can tie a small knot in the line, use tape or a marker) P Pull the line back up from the casing.

The craftsmanship was generally on target with no major problems identified due to construction There are three items of note, however: 1. He has not yet abandoned the existing septic tank and will do so towards the conclusion of the project. He said you are already aware of this and are planning to inspect when he has done this work. He was reminded of the need to contact your office for inspection of that task. 2. The distribution box needs hydraulic cement around the pipe penetrations. The contractor was going to complete that right after I left and I told him he need not leave that open for observation. 3. The pipe elbow into the distribution box needs some attention per my earlier email to the design engineer. Please let me know if you have any questions.

Additionally we spoke to the contractor, John Butt, regarding the same. We have experienced numerous problems in the past with the use of 2" tees in this specific application as although 310 CMR 15.232 (3) (d)specifies distribution boxes to have water tight covers, 2" pvc tees on force mains often cause enough velocity, turbulence and inflow that effluent by passes the distribution box covers and causes effluent break out in the area surrounding the distribution box, as a solution, we recommended an elbow. We appreciate and respect your concerns with this suggestion, and as an alternative, suggest expanding the final 4 feet of 2" force main to 4" sch 40 PVC force main with a 4" tee installed immediately inside the distribution box. We have also used and specified this alternative in the past and it seems to remedy the problem. Please let us kiiow if this is acceptable and we will advise the Contractor to proceed accordingly and specify this detail in these design circumstances moving forward.
